NEW QUESTION # 87
Which of the following actions should the server administrator perform on the server?
- A. Close port 3389 and rerun the scan.
- B. Close ports 80 and 443 and rerun the scan.
- C. Close all ports and rerun the scan.
- D. Close ports 69 and 1010 and rerun the scan.
Answer: A
Explanation:
The server administrator should close port 3389 and rerun the scan. Port 3389 is used for Remote Desktop Protocol (RDP), which allows remote access and control of a server. RDP is vulnerable to brute-force attacks, credential theft, and malware infection. Closing port 3389 can prevent unauthorized access and improve the security of the server. The other ports are not as risky as port 3389 and can be left open for legitimate purposes.

NEW QUESTION # 88
A site is considered a warm site when it:
- A. has basic technical facilities connected to it.
- B. is fully operational and continuously providing services.
- C. is almost ready to take over all operations from the primary site.
- D. has faulty air conditioning that is awaiting service.
Answer: C
Explanation:
A warm site is a backup site that has some of the necessary hardware, software, and network resources to resume operations, but not all of them. A warm site requires some time and effort to become fully operational.
A warm site is different from a cold site, which has minimal or no resources, and a hot site, which has all the resources and is ready to take over immediately.

NEW QUESTION # 89
A technician is monitoring a server and notices there is only one NIC plugged in. but the server has two. The NIC is oversaturated, and the technician would like to increase the available bandwidth. Which of the following solutions would be the BEST option to increase the speed of this NIC?
- A. Active-active
- B. Link aggregation
- C. Heartbeat
- D. Most recently used
Answer: B
Explanation:
This is the best solution to increase the speed of the NIC because link aggregation is a technique that combines multiple physical network interfaces into a single logical interface. This can increase the bandwidth, redundancy, and load balancing of network traffic. Link aggregation requires both the server and the switch to support it and be configured accordingly.

NEW QUESTION # 90
A server is performing slowly, and users are reporting issues connecting to the application on that server. Upon investigation, the server administrator notices several unauthorized services running on that server that are successfully communicating to an external site. Which of the following are MOST likely causing the issue? (Choose two.)
- A. Unnecessary services are disabled on the server
- B. Adware is installed on the users' devices
- C. The firewall rule for the server is misconfigured
- D. The server is infected with a virus
- E. SELinux is enabled on the server
- F. Intrusion detection is enabled on the network
Answer: C,D
Explanation:
Adware on the users' machine is a large assumption. If everyone is affected it's unlikely that everyone has adware, and more likely that the server has a virus slowing it down.
The server most likely got the virus from open ports i.e. misconfigured firewall.
NEW QUESTION # 91
Which of the following BEST describes a guarantee of the amount of time it will take to restore a downed service?
- A. MTTR
- B. MTBF
- C. RTO
- D. SLA
Answer: C
Explanation:
RTO stands for Recovery Time Objective and it is a metric that defines the maximum acceptable amount of time that a system or service can be unavailable after a disaster or disruption. RTO is part of the business continuity planning and disaster recovery planning processes. RTO ensures a guarantee of the amount of time it will take to restore a downed service by setting a target or goal for recovery. RTO can vary depending on the criticality and priority of the service.

NEW QUESTION # 92
A company wants to deploy software to all users, Out very few of men will be using the software at any one point in time. Which of the following licensing models would be BEST lot the company?
- A. Per site
- B. Per instance
- C. Per core
- D. Per concurrent user
Answer: D
Explanation:
Explanation
Per concurrent user licensing is a model that allows a fixed number of users to access the software at any one point in time. This model is best for the company that wants to deploy software to all users, but very few of them will be using the software at any one point in time. This way, the company can save money by paying only for the number of simultaneous users, rather than for every user who has access to the software. Per site licensing is a model that allows unlimited users within a specific location to use the software. Per core licensing is a model that charges based on the number of processor cores on the server where the software is installed. Per instance licensing is a model that charges based on the number of copies of the software running on different servers or virtual machines. References:

NEW QUESTION # 93
A technician recently applied a critical OS patch to a working sever. After rebooting, the technician notices the server Is unable to connect to a nearby database server. The technician validates a connection can be made to the database from another host. Which of the following is the best NEXT step to restore connectivity?
- A. Roll back the applied patch.
- B. Enable HIDS.
- C. Change the service account permissions.
- D. Check the host firewall I rule.
Answer: D
Explanation:
A host firewall is a software that controls the incoming and outgoing network traffic on a server based on predefined rules and filters. It can block or allow certain ports, protocols, or addresses that are used for communication with other servers or devices. If a server is unable to connect to another server after applying a patch, it is possible that the patch changed or added a firewall rule that prevents the connection. The administrator should check the host firewall rule and modify it if necessary to restore connectivity. Verified Reference: [Host firewall], [Network connection]

Which of the following can be BEST described as the amount of time a company can afford to be down during recovery from an outage?
- A. MTTR
- B. MTBF
- C. RTO
- D. SLA
Answer: C
Explanation:
The term that best describes the amount of time a company can afford to be down during recovery from an outage is RTO. RTO (Recovery Time Objective) is a metric that defines the maximum acceptable downtime for an application, system, or process after a disaster or disruption. RTO helps determine the level of urgency and resources required for restoring normal business operations. RTO is usually measured in minutes, hours, or days, depending on the criticality and impact of the service.

A server in a remote datacenter is no longer responsive. Which of the following is the BEST solution to investigate this failure?
- A. Out-of-band management
- B. A Secure Shell connection
- C. Access via a crash cart
- D. Remote desktop
Answer: A
Explanation:
The best solution to investigate the failure of a server in a remote datacenter is out-of-band management. Out-of-band management is a method of accessing and controlling a server or a device using a dedicated channel that is separate from its normal network connection. Out-of-band management can use various technologies, such as serial ports, modems, KVM switches, or dedicated management cards or interfaces. Out-of-band management can provide remote access to servers or devices even when they are powered off, unresponsive, or disconnected from the network. Out-of-band management can enable troubleshooting, configuration, maintenance, or recovery tasks without requiring physical presence at the server location.
