NEW QUESTION # 17
In the case of IP Clos data center five-stage fabric design, what are two rotes of the super spines? (Choose two.)
- A. Super spines connect to all spine devices within the five-stage architecture.
- B. Super spines are used to interconnect two different data center pods.
- C. Super spines are used to connect leaf nodes within a data center pod.
- D. Super spines are always connected to an external data center gateway.
Answer: A,B
Explanation:
In the case of IP Clos data center five-stage fabric design, the super spines are the devices that provide the highest level of aggregation in the network. They have two main roles:
* Super spines are used to interconnect two different data center pods. A pod is a cluster of leaf and spine devices that form a 3-stage Clos topology. A 5-stage Clos topology consists of multiple pods that are connected by the super spines. This allows for scaling the network to support more devices and bandwidth.
* Super spines connect to all spine devices within the five-stage architecture. The spine devices are the devices that provide the second level of aggregation in the network. They connect to the leaf devices, which are the devices that provide access to the end hosts. The super spines connect to all the spine devices in the network, regardless of which pod they belong to. This provides any-to-any connectivity between the pods and enables optimal routing and load balancing.
The following two statements are incorrect in this scenario:
* Super spines are used to connect leaf nodes within a data center pod. This is not true, because the leaf nodes are connected to the spine nodes within the samepod. The super spines do not connect to the leaf nodes directly, but only through the spine nodes.
* Super spines are always connected to an external data center gateway. This is not true, because the super spines are not necessarily involved in the external connectivity of the data center. The external data center gateway is a device that provides the connection to the outside network, such as the Internet or another data center. The external data center gateway can be connected to the super spines, the spine nodes, or the leaf nodes, depending on the design and the requirements of the network.

NEW QUESTION # 18
Which two statements are correct about repairing a Juniper Apstra cabling map before deploying your blueprint? (Choose two.)
- A. Apstra can use LLDP data from the leaf devices to update the leaf-to-generic connections in the cabling map.
- B. Apstra can use LLDP data from the spine-to-lea! fabric devices to update the connections in the cabling map.
- C. You must manually change the cabling map to update leaf-to-generic links.
- D. You must manually change the cabling map to update spine-to-leaf fabric links.
Answer: A,B
Explanation:
The cabling map is a graphical representation of the physical connections between the devices in the data center fabric. It shows the status of the cables, interfaces, and BGP sessions for each device. You can use the cabling map to verify and repair the cabling before deploying your blueprint. Based on the web search results, we can infer the following statements:
* Apstra can use LLDP data from the spine-to-leaf fabric devices to update the connections in the cabling map. This is true because Apstra can collect LLDP data from the devices using the Generic Graph Collector processor and use it to update the cabling map automatically. LLDP is a protocol that allows devices to exchange information about their identity, capabilities, and neighbors12.
* Apstra can use LLDP data from the leaf devices to update the leaf-to-generic connections in the cabling map. This is true because Apstra can also collect LLDP data from the leaf devices and use it to update the connections to the generic devices, such as routers, firewalls, or servers. Generic devices are devices that are not managed by Apstra but are part of the data center fabric23.
* You must manually change the cabling map to update spine-to-leaf fabric links. This is false because Apstra can use LLDP data to update the spine-to-leaf fabric links automatically, as explained above. However, you can also manually change the cabling map to override the Apstra-generated cabling, if needed24.
* You must manually change the cabling map to update leaf-to-generic links. This is false because Apstra can use LLDP data to update the leaf-to-generic links automatically, as explained above. However, you can also manually change the cabling map to override the Apstra-generated cabling, if needed24. References:

NEW QUESTION # 19
You want to apply a configlet to a specific device using Juniper Apstra. Which two parameters would be used to accomplish this task? (Choose two.)
- A. form factor
- B. hostname
- C. port group
- D. tags
Answer: B,D
Explanation:
To apply a configlet to a specific device using Juniper Apstra, you need to specify the device's hostname and tags. The hostname is the unique identifier of the device in the Apstra system, and the tags are the labels that you can assign to the device to group it with other devices that share the same characteristics. You can use the hostname and tags to filter the devices that you want to apply the configlet to in the blueprint catalog12.

NEW QUESTION # 20
Exhibit.
Referring to the exhibit, which role does Device A serve in an IP fabric?
- A. spine
- B. super spine
- C. server
- D. leaf
Answer: A
Explanation:
Device A serves as a spine in an IP fabric. An IP fabric is a network architecture that uses a spine-leaf topology to provide high performance, scalability, and reliability for data center networks. A spine-leaf topology consists of two layers of devices: spine devices and leaf devices. Spine devices are the core devices that interconnect all the leaf devices using equal-cost multipath (ECMP) routing. Leaf devices are the edge devices that connect to the servers, storage, or other network devices. In the exhibit, Device A is connected to four leaf devices using multiple links, which indicates that it is a spine device. The other options are incorrect because:
* A. leaf is wrong because a leaf device is an edge device that connects to the servers, storage, or other network devices. In the exhibit, Device A is not connected to any servers, storage, or other network devices, but only to four leaf devices, which indicates that it is not a leaf device.
* C. super spine is wrong because a super spine device is a higher-level device that interconnects multiple spine devices in a large-scale IP fabric. A super spine device is typically used when the number of leaf devices exceeds the port density of a single spine device. In the exhibit, Device A is not connected to any other spine devices, but only to four leaf devices, which indicates that it is not a super spine device.
* D. server is wrong because a server device is a compute or storage device that connects to a leaf device in an IP fabric. A server device is typically the end host that provides or consumes data in the network.
In the exhibit, Device A is not connected to any leaf devices, but only to four leaf devices, which indicates that it is not a server device. References:

NEW QUESTION # 21
You are using Juniper Apstra to design a data center fabric.
In this scenario, which object type associates a specific vendor model to a logical device?
- A. templates
- B. agent profiles
- C. interface map
- D. device profiles
Answer: D
Explanation:
Device profiles are objects that associate a specific vendor model to a logical device in Juniper Apstra. Device profiles contain extensive hardware model details, such as form factor, ASIC, CPU, RAM, ECMP limit, and supported features. Device profiles also define how configuration is generated, how telemetry commands are rendered, and how configuration is deployed on a device. Device profiles enable the Apstra system to render and deploy the configuration according to the Apstra Reference Design12. References:
* Device Profiles
* Juniper Device Profiles
NEW QUESTION # 22
You have a virtual network that needs controlled access to other virtual networks in the same routing zone.
Using the Juniper Apstra Ul. which feature would be used to accomplish this task?
- A. anti-affinity policy
- B. routing policy
- C. security policy
- D. interface policy
Answer: C
Explanation:
A security policy is the feature that would be used to accomplish the task of controlling access to other virtual networks in the same routing zone using the Juniper Apstra UI. A security policy allows you to define rules that specify which traffic is allowed or denied between different virtual networks, IP endpoints, or routing zones. A security policy can be applied to one or more virtual networks in the same routing zone, and it can use various criteria to match the traffic, such as source and destination IP addresses, protocols, ports, or tags. A security policy can also support DHCP relay, which enables the forwarding of DHCP requests from one virtual network to another. The other options are incorrect because:
* A. interface policy is wrong because an interface policy is a feature that allows you to configure the interface parameters for the devices in a blueprint, such as interface names, speeds, types, or descriptions. An interface policy does not affect the access control between different virtual networks in the same routing zone.
* B. anti-affinity policy is wrong because an anti-affinity policy is a feature that allows you to prevent certain devices or logical devices from being placed in thesame rack or leaf pair in a blueprint. An anti-affinity policy is used to enhance the availability and redundancy of the network, not to control the access between different virtual networks in the same routing zone.
* C. routing policy is wrong because a routing policy is a feature that allows you to configure the routing parameters for the devices in a blueprint, such as routing protocols, autonomous system numbers, route filters, or route maps. A routing policy does not affect the access control between different virtual networks in the same routing zone, unless the routing policy is used to filter or modify the routes exchanged between different routing zones.

NEW QUESTION # 23
In the Juniper Apstra Ul. which three resources are assigned under the Resources menu? (Choose three.)
- A. ASN pools
- B. logical device pools
- C. IP address pools
- D. VNI pools
- E. VTEP pools
Answer: A,C,D
Explanation:
In the Juniper Apstra UI, the Resources menu allows you to create and manage global and local resources that are used for various elements of the network design and configuration. The Resources menu includes the following three types of resources that can be assigned to the network devices and virtual networks:
* ASN pools: These are pools of autonomous system numbers (ASNs) that are used for the underlay routing protocol (EBGP) between the leaf and spine devices. You can create ASN pools with either
2-byte or 4-byte ASNs, and assign them to the logical devices in the blueprint.
* VNI pools: These are pools of virtual network identifiers (VNIs) that are used for the overlay network (VXLAN) between the end hosts. You can create VNI pools with a range of VNIs, and assign them to the virtual networks in the blueprint.
* IP address pools: These are pools of IPv4 or IPv6 addresses that are used for various purposes in the network, such as the loopback addresses for the devices, the IP prefixes for the virtual networks, the host
* IP addresses for the end hosts, and the gateway IP addresses for the IRB interfaces. You can create IP address pools with a range of IP addresses, and assign them to the logical devices and virtual networks in the blueprint.
The following two types of resources are not assigned under the Resources menu:
* VTEP pools: These are not resources that can be created or assigned by the user. VTEPs are VXLAN tunnel endpoints that are automatically generated by the Apstra server based on the loopback IP addresses of the devices. VTEPs are used as the source and destination IP addresses for the VXLAN tunnels in the overlay network.
* Logical device pools: These are not resources that can be created or assigned by the user. Logical device pools are groups of logical devices that share the same role, interface map, and resource assignments in the blueprint. Logical device pools are used to simplify the network design and configuration by applying the same settings to multiple devices.

NEW QUESTION # 24
In the Juniper Apstra Ul. you are creating a VNI pool for virtual networks.
In this scenario, which VNI range is acceptable?
- A. The valid VNI range is 2 through 4096.
- B. The valid VNI range is 4096 through 16777214.
- C. The valid VNI range is 1 through 10000.
- D. Any range is acceptable for the VNI pool.
Answer: B
Explanation:
In the Juniper Apstra UI, you can create VNI pools for virtual networks that use VXLAN encapsulation in the overlay network. A VNI pool is a resource pool that contains a range of VNIs that can be assigned to the virtual networks. The valid VNI range for a VNI pool is 4096 through 16777214, according to the VXLAN standard1. Therefore, the statement B is correct in this scenario.
The following three statements are incorrect in this scenario:
* Any range is acceptable for the VNI pool. This is not true, because the VNI range has a lower and upper limit defined by the VXLAN standard1. The lower limit is 4096, and the upper limit is 16777214. Any VNI outside this range is invalid and cannot be used for VXLAN encapsulation.
* The valid VNI range is 2 through 4096. This is not true, because the VNI range does not start from 2, but from 4096. The VNIs from 2 to 4095 are reserved and cannot be used for VXLAN encapsulation1.
* The valid VNI range is 1 through 10000. This is not true, because the VNI range does not include 1, which is also reserved and cannot be used for VXLAN encapsulation1. The VNI range also does not end at 10000, but at 16777214, which is the maximum possible value for a 24-bit VNI field1.

NEW QUESTION # 25
Exhibit.
Referring to the exhibit, how many tack types ate used in the staged blueprint?
- A. three
- B. six
- C. two
- D. seven
Answer: C
Explanation:
Referring to the exhibit, the image shows the Racks table under the Staged menu in the Juniper Apstra UI. The Racks table displays the details of the racks that are used in the blueprint, such as the name, rack type, and date. The rack type is a resource that defines the type and number of leaf devices, access switches, and/or generic systems that are used in rack builds1. The image shows seven racks in the table, but only two rack types: BorderLeaf and ServerRack. Therefore, the statement D is correct in this scenario.
The following three statements are incorrect in this scenario:
* A. six. This is not true, because there are not six rack types in the table, but only two. The number six corresponds to the number of racks that have the same rack type: ServerRack.
* B. three. This is not true, because there are not three rack types in the table, but only two. The number
* three does not correspond to any relevant information in the table or the image.
* C. seven. This is not true, because there are not seven rack types in the table, but only two. The number seven corresponds to the total number of racks in the table, not the rack types.

NEW QUESTION # 26
Exhibit.
Which two statements ate correct about the information shown in the exhibit? (Choose two.)
- A. The system is fully managed by Juniper Apstra.
- B. The device shown is a generic system.
- C. Four physical interfaces exist in a LAG facing the leaf pair.
- D. The physical ports are not part of the LAG.
Answer: B,C
Explanation:
According to the Juniper documentation1, a generic system is a device that is not managed by Juniper Apstra and does not have a specific role or type assigned to it. A generic system can be used to represent a server, a firewall, a load balancer, or any other device that is not part of the fabric. In the exhibit, the device shown is a generic system, as indicated by its role, system type, and management level. Therefore, the correct answer is B: The device shown is a generic system.
According to the Juniper documentation2, a LAG is a link aggregation group that bundles multiple physical interfaces into a single logical interface. A LAG can provide increased bandwidth, redundancy, and load balancing for the network traffic. In the exhibit, the device shown has four physical interfaces that are part of a LAG, as indicated by their description and li_type. The LAG is facing the leaf pair, which are the two switches that connect to the device. Therefore, the correct answer is C. Four physical interfaces exist in a LAG facing the leaf pair.

NEW QUESTION # 27
Which two statements are correct about Time Voyager? {Choose two.)
- A. Time Voyager retains the five most recent blueprint commits.
- B. Time Voyager retains the last ten blueprint commits.
- C. Time Voyager retains up to twenty-five saved revisions.
- D. Time Voyager retains all of the blueprint revisions from the last Juniper Apstra backup.
Answer: A,C
Explanation:
Time Voyager is a feature of Juniper Apstra that allows you to restore previous revisions of a blueprint, which is a logical representation of your network design and configuration. Time Voyager automatically saves the five most recent blueprint commits, which are the changes that you apply to the network. You can also manually save up to twenty-five revisions by keeping them, which prevents them from being overwritten by new commits. Therefore, the correct answer is B and D. Time Voyager retains the five most recent blueprint commits and Time Voyager retains up to twenty-five saved revisions.

NEW QUESTION # 28
Which two statements about VXLAN VNIs are correct? (Choose two.)
- A. VNIs are alphanumeric values.
- B. VNIs identify a broadcast domain
- C. VNIs can have over 16 million unique values.
- D. VNIs identify a collision domain.
Answer: B,C
Explanation:
VXLAN VNIs are virtual network identifiers that are used to identify and isolate Layer 2 segments in the overlay network. VXLAN VNIs have the following characteristics:
* VNIs can have over 16 million unique values. This is because VXLAN VNIs are 24-bit fields that can range from 4096 to 16777214, according to the VXLAN standard1. This allows VXLAN to support a large number of Layer 2 segments and tenants in the network.
* VNIs identify a broadcast domain. This is because VXLAN VNIs are used to group the end hosts that belong to the same Layer 2 segment and can communicate with each other using VXLAN tunnels. The VXLAN tunnels are established using the VTEP information that is distributed by EVPN. The VTEPs are VXLAN tunnel endpoints that perform the VXLAN encapsulation and decapsulation. The VXLAN tunnels preserve the Layer 2 semantics and support the broadcast, unknown unicast, and multicast traffic within the same VNI2.
The following two statements are incorrect in this scenario:
* VNIs identify a collision domain. This is not true, because VXLAN VNIs do not identify a collision domain, which is a network segment where data packets can collide with each other. VXLAN VNIs identify a broadcast domain, which is a network segment where broadcast traffic can reach all the devices. Collision domains are not relevant in VXLAN networks, because VXLAN uses MAC-in-UDP encapsulation and IP routing to transport the Layer 2 frames over the Layer 3 network1.
* VNIs are alphanumeric values. This is not true, because VXLAN VNIs are numeric values, not alphanumeric values. VXLAN VNIs are 24-bit fields that can range from 4096 to 16777214, according to the VXLAN standard1. Alphanumeric values are values that contain both letters and numbers, such as ABC123 or 1A2B3C.

NEW QUESTION # 29
You must configure a static route for traffic to exit a configured routing zone. In the Juniper Apstra Ul. where would you accomplish this task?
- A. under Staged -> Connectivity Templates
- B. under Active -> Virtual -> Routing Zones
- C. under Staged -> Virtual -> Routing Zones
- D. under Active -> Connectivity Templates
Answer: A
Explanation:
To configure a static route for traffic to exit a configured routing zone, you need to use the Connectivity Templates feature in the Juniper Apstra UI. A Connectivity Template is a set of configuration parameters that can be applied to a device or a group of devices in a blueprint. You can use Connectivity Templates to configure static routes, BGP, OSPF, and other network services. To create a Connectivity Template, you need to go to the Staged tab and select Connectivity Templates from the left menu. Then, you can click on the + icon to create a new template. You can specify the name, description, andscope of the template. The scope determines which devices or device groups the template will be applied to. You can also specify the order of the template, which determines the priority of the template when multiple templates are applied to the same device. After creating the template, you can add configuration items to the template. To add a static route, you need to select Static Route from the drop-down menu and enter the destination network, subnet mask, and next-hop IP address. You can also specify the administrative distance and the track object for the static route.
After adding the configuration items, you need to save the template and commit the changes to the blueprint.
The other options are incorrect because:
* A. under Active -> Virtual -> Routing Zones is wrong because this option allows you to view and modify the existing routing zones, but not to configure static routes for them.
* B. under Staged -> Virtual -> Routing Zones is wrong because this option allows you to create and delete routing zones, but not to configure static routes for them.
* C. under Active -> Connectivity Templates is wrong because this option allows you to view the existing connectivity templates, but not to create or modify them. References:

NEW QUESTION # 30
What is the purpose of a Juniper Apstra rack?
- A. It stores IP address and ASN pool information.
- B. It stores device port data rates and vendor information.
- C. It stores information on how leaf nodes connect to generic devices
- D. It stores information on how pods connect to super spines.
Answer: C
Explanation:
A Juniper Apstra rack is a physical entity that contains one or more network devices, such as leaf nodes, access switches, or generic systems. A rack is used to organize and manage the network devices in the Apstra software application. A rack has the following characteristics:
* It stores information on how leaf nodes connect to generic devices. This is because a rack can include generic systems, which are devices that are not managed by Juniper Apstra, but are connected to the network. A generic system can be a server, a firewall, a load balancer, or any other device that has a networkinterface. A rack stores the information on how the leaf nodes, which are the devices that provide access to the end hosts, connect to the generic devices, such as the port number, the link speed, the LAG mode, and the roles1.
* It has a rack type, which defines the type and number of leaf devices, access switches, and/or generic systems that are used in the rack. A rack type is a resource that is created in the data center design phase, and it does not specify the vendor or the model of the devices. A rack type can be predefined or custom-made, and it can be used to create multiple racks with the same structure and configuration2.
* It has a rack build, which assigns the specific vendor and model of the devices to the rack. A rack build is created in the staged phase, and it uses the rack type as a template. A rack build can also assign the resources, such as the IP addresses, the ASNs, and the VNIs, to the devices in the rack3.
* It has a rack deployment, which applies the network configuration and services to the devices in the rack. A rack deployment is performed in the active phase, and it uses the rack build as a reference. A rack deployment can also monitor the network performance and compliance of the devices in the rack4.
The following three statements are incorrect in this scenario:
* It stores information on how pods connect to super spines. This is not true, because a rack does not store any information on the pod or the super spine level of the network. A pod is a cluster of leaf and spine devices that form a 3-stage Clos topology, and a super spine is a device that connects multiple pods in a
5-stage Clos topology. A rack only stores information on the leaf and the access level of the network1.
* It stores IP address and ASN pool information. This is not true, because a rack does not store any information on the IP address and ASN pools. IP address and ASN pools are resources that are created in the data center design phase, and they contain a range of IP addresses and ASNs that can be assigned to the devices and the virtual networks. A rack only uses the IP address and ASN pools to assign the resources to the devices in the rack build2.
* It stores device port data rates and vendor information. This is not true, because a rack does not store any information on the device port data rates and vendor information. The device port data rates and vendor information are specified in the rack build, which assigns the specific vendor and model of the devices to the rack. A rack only uses the rack build to apply the network configuration and services to the devices in the rack deployment3.

NEW QUESTION # 31
Which protocol is used to advertise EVPN routes?
- A. BGP
- B. OSPF
- C. IS-IS
- D. RIP
Answer: A
Explanation:
BGP is the protocol used to advertise EVPN routes. EVPN routes are a new type of BGP network layer reachability information (NLRI) that carry MAC address and IP prefix information for Ethernet VPNs. EVPN routes are exchanged between PEs using BGP multiprotocol extensions (MP-BGP) over MPLS, VXLAN, SR, or SRv6 tunnels. EVPN routes enable PEs to learn the reachability of MAC addresses and IP prefixes of different sites within the same EVPN instance. EVPN routes also support various features such as fast convergence, redundancy, aliasing, and inter-subnet routing. The other options are incorrect because:
* A. OSPF is wrong because OSPF is an interior gateway protocol (IGP) that is used to advertise IP routes within an autonomous system. OSPF is not used to advertise EVPN routes, which are a type of BGP NLRI that carry MAC address and IP prefix information for Ethernet VPNs.
* C. IS-IS is wrong because IS-IS is an interior gateway protocol (IGP) that is used to advertise IP routes and MPLS labels within an autonomous system. IS-IS is not used to advertise EVPN routes, which are a type of BGP NLRI that carry MAC address and IP prefix information for Ethernet VPNs.
* D. RIP is wrong because RIP is an interior gateway protocol (IGP) that is used to advertise IP routes within an autonomous system. RIP is not used to advertise EVPN routes, which are a type of BGP NLRI that carry MAC address and IP prefix information for Ethernet VPNs. References:

NEW QUESTION # 32
When editing a device configuration to install some manual changes, which procedure should be followed?
- A. Add a persistent change to a device configuration with a configlet.
- B. Delete the device from the Juniper Apstra system, change the configuration, then re-import the device.
- C. Edit the configuration on the device directly by the CLI; the changes will automatically be adjusted in the Juniper Apstra configuration
- D. Edit the pristine configuration of the device.
Answer: A
Explanation:
A configlet is a small piece of configuration that can be applied to a device or a group of devices to make persistent changes that are not overwritten by Apstra. Configlets can be used to install manual changes that are not part of the Apstra rendered configuration, such as custom commands, scripts, or features. Configlets can be created, edited, and deleted from the Apstra GUI or CLI12. References:

NEW QUESTION # 33
You have designed your fabric in Juniper Apstra prior to deploying the network devices.
Which Apstra element in the Staged tab would be used to assist the team that is installing and cabling the devices?
- A. Virtual Networks table
- B. Links table
- C. Connectivity Templates
- D. Managed Devices list
Answer: B
Explanation:
The Links table in the Staged tab shows the physical connections between the devices in the fabric. It provides information such as the source and destination device names, hostnames, serial numbers, roles, interfaces, and link status. The Links table can be used to assist the team that is installing and cabling the devices by verifying that the devices are connected correctly and that the links are operational. The Links table can also be used to troubleshoot any connectivity issues that may arise during the installation process. For more information, see Links (Staged). References:

NEW QUESTION # 34
Juniper Apstra has indicated an anomaly with respect to cabling.
What are two ways to remediate the issue? (Choose two.)
- A. Set the invalid ports to a disabled state.
- B. Have Apstra autoremediate the cabling map using LLDP.
- C. Manually edit the cabling map.
- D. Redeploy the errant device.
Answer: B,C
Explanation:
A cabling anomaly is an issue that occurs when the physical connections between the devices in the data center fabric do not match the expected connections based on the Apstra Reference Design. A cabling anomaly can cause problems such as incorrect routing, suboptimal traffic flow, or device isolation. To remediate the issue, you can use one or both of the following methods:
* Manually edit the cabling map. This allows you to override the Apstra-generated cabling and specify the correct connections between the devices. You can use the Apstra UI or the Apstra CLI to edit the cabling map and apply the changes to the fabric12.
* Have Apstra autoremediate the cabling map using LLDP. This allows Apstra to collect LLDP data from the devices and use it to update the cabling map automatically. LLDP is a protocol that allows devices to exchange information about their identity, capabilities, and neighbors. Apstra can use the LLDP data to detect and correct any cabling errors in the fabric34. References:

NEW QUESTION # 35
What is the function of the Revert button in the Juniper Apstra Ul?
- A. The Revert button deletes any uncommitted changes within Apstra.
- B. The Revert button will rollback to the previous configuration of a specified device.
- C. The Revert button performs a rollback 0 on Juniper devices in the fabric.
- D. The Revert button will undo the last change made to the configuration.
Answer: A
Explanation:
According to the Juniper documentation1, the Revert button is located on the Uncommitted tab of the blueprint page. The Uncommitted tab shows the changes that have been staged but not yet committed to the network. The Revert button allows you to discard any uncommitted changes and revert to the last committed state of the blueprint.

NEW QUESTION # 36
You want to make a widget appear on the main dashboard in Juniper Apstra. In this scenario, which statement is correct?
- A. On the blueprint dashboard, click on the Add Widget option.
- B. Set the Default toggle switch to On for the desired widget.
- C. When creating the widget, select the Add to Blueprint Dashboard option.
- D. Widgets automatically appear on the blueprint dashboard.
Answer: B
Explanation:
In Juniper Apstra, a widget is a graphical element that displays data from an intent-based analytics (IBA) probe. A widget can be used to monitor different aspects of the network and raise alerts to any anomalies. A widget can be viewed by itself or added to an analytics dashboard. A dashboard is a collection of widgets that can be customized and organized according to the user's preference1.
The main dashboard in Juniper Apstra is the blueprint dashboard, which is the default view that shows the network information and configuration for the active blueprint. A blueprint is a logical representation of the network design and intent. The blueprint dashboard can display the system-generated dashboards, the user-generated dashboards, and the individual widgets that are relevant to the network2.
To make a widget appear on the main dashboard in Juniper Apstra, the user needs to set the Default toggle switch to On for the desired widget. This will add the widget to the blueprint dashboard, where it can be viewed along with other network information. The user can also remove the widget from the blueprint dashboard by setting the Default toggle switch to Off for the widget3. Therefore, the statement D is correct in this scenario.
The following three statements are incorrect in this scenario:
* When creating the widget, select the Add to Blueprint Dashboard option. This is not true, because there is no such option when creating a widget in Juniper Apstra. The user can only select the widget type, the probe, and the display mode when creating a widget4. To add the widget to the blueprint dashboard, the user needs to set the Default toggle switch to On for the widget after creating it3.
* On the blueprint dashboard, click on the Add Widget option. This is not true, because there is no such option on the blueprint dashboard in Juniper Apstra. The user can only view, edit, or delete the existing widgets and dashboards on the blueprint dashboard2. To add a widget to the blueprint dashboard, the user needs to set the Default toggle switch to On for the widget from the widgets table view3.
* Widgets automatically appear on the blueprint dashboard. This is not true, because widgets do not automatically appear on the blueprint dashboard in Juniper Apstra. The user needs to manually add the widgets to the blueprint dashboard by setting the Default toggle switch to On for the widgets that they
* want to see on the blueprint dashboard3. The only exception is the widgets that are part of the system-generated dashboards, which are automatically created and added to the blueprint dashboard based on the state of the active blueprint2.

NEW QUESTION # 37
In the Juniper Apstra design phase, which object dictates port count, port speed, and how the ports would be used?
- A. network devices
- B. logical devices
- C. interface map
- D. rack type
Answer: C
Explanation:
Interface maps are objects that map interfaces between logical devices and physical hardware devices in the Juniper Apstra design phase. They dictate port count, port speed, and how the ports would be used for achieving the intended network configuration rendering. Interface maps also allow you to select device ports, transformations, and interfaces, provision breakout ports, and disable unused ports.

NEW QUESTION # 38
What are two system-defined user roles that are available in Juniper Apstra? (Choose two.)
- A. authorized
- B. user
- C. root
- D. viewer
Answer: B,D
Explanation:
Juniper Apstra provides four system-defined user roles that are available in the Apstra GUI environment. They are: administrator, device_ztp, viewer, and user1. Based on the web search results, we can infer the following statements:
* viewer: This role includes permissions to only view various elements in the Apstra system, such as blueprints, devices, design, resources, external systems, platform, and others. Users with this role cannot create, edit, or delete any element12.
* user: This role includes permissions to view and edit various elements in the Apstra system, such as blueprints, devices, design, resources, external systems, platform, and others. Users with this role cannot create or delete any element12.
* authorized: This is not a system-defined user role in Juniper Apstra. It is a term used to describe users who have been authenticated by an external system, such as LDAP, Active Directory, TACACS+, or RADIUS3.
* root: This is not a system-defined user role in Juniper Apstra. It is a term used to describe the superuser account on a Linux system, which has full access to all commands and files. Creating a user in the Apstra GUI does not provide that user access to the Apstra platform via SSH. To access the Apstra platform via SSH, you must create a local Linux system user4. References:

NEW QUESTION # 39
Exhibit.
Referring to the exhibit, how many broadcast domains will an Ethernet frame pass through when traversing the IP fabric from Server A to Server B?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: A
Explanation:
Referring to the exhibit, the image shows a simplified diagram of an IP fabric network connecting two servers, labeled as Server A and Server B. The IP fabric is a network architecture that uses a Clos topology to provide high bandwidth, low latency, and scalability for data center networks. The IP fabric consists of spine and leaf devices that use BGP as the routing protocol and VXLAN as the overlay technology1.
A broadcast domain is a logical portion of a network where any device can directly transmit broadcast frames to other devices at the data link layer (OSI Layer 2). A broadcast frame is a frame that has a destination MAC address of all ones (FF:FF:FF:FF:FF:FF), which means that it is intended for all devices in the same broadcast domain. A broadcast domain is usually bounded by a router, which does not forward broadcast frames to other networks2.
In the exhibit, there are two broadcast domains that an Ethernet frame will pass through when traversing the IP fabric from Server A to Server B. The first broadcast domain is the one that contains Server A and the leaf device that it is connected to. The second broadcast domain is the one that contains Server B and the leaf device that it is connected to. The IP fabric itself is not a broadcast domain, because it uses IP routing and VXLAN encapsulation to transport the Ethernet frames over the Layer 3 network. Therefore, the statement C is correct in this scenario.
The following three statements are incorrect in this scenario:
* A. 1. This is not true, because there are not one, but two broadcast domains that an Ethernet frame will pass through when traversing the IP fabric from Server A to Server B. The IP fabric itself is not a broadcast domain, because it uses IP routing and VXLAN encapsulation to transport the Ethernet frames over the Layer 3 network.
* B. 4. This is not true, because there are not four, but two broadcast domains that an Ethernet frame will pass through when traversing the IP fabric from Server A to Server B. The spine devices and the leaf devices that are not connected to the servers are not part of the broadcast domains, because they use IP routing and VXLAN encapsulation to transport the Ethernet frames over the Layer 3 network.
* D. 3. This is not true, because there are not three, but two broadcast domains that an Ethernet frame will pass through when traversing the IP fabric from Server A to Server B. The IP fabric itself is not a broadcast domain, because it uses IP routing and VXLAN encapsulation to transport the Ethernet frames over the Layer 3 network.
