CompTIA CompTIA Certifications SK0-005 Questions & Answers

• Question 371:

  A company's servers are all displaying the wrong time. The server administrator confirms the time source is correct. Which of the following is MOST likely preventing the servers from obtaining the correct time?

  A. A firewall

  B. An antivirus

  C. A HIDS

  D. User account control

  Correct Answer: A

• Question 372:

  A server administrator encounters some issues with the server OS after applying monthly patches. Which of the following troubleshooting steps should the administrator perform?

  A. Implement rollback procedures.

  B. Upgrade the drivers.

  C. Reinstall the OS.

  D. Reboot the server.

  Correct Answer: A

  This option would restore the server OS to a previous state before applying the monthly patches. This would help troubleshoot the issues caused by the patches and determine if they are compatible with the server OS. The other options would either not address the issues, cause data loss, or require more time and resources

• Question 373:

  An administrator notices that a file server is filling up quickly but has many of the same files in different directories. Which of the following storage management techniques would resolve this issue?

  A. Provisioning

  B. Encryption

  C. Deduplication

  D. Partitioning

  Correct Answer: C

  The storage management technique that would resolve this issue is deduplication.

  Deduplication is a technique that identifies and eliminates duplicate copies of data in a storage system. This reduces the amount of storage capacity needed and can improve backup and restore times. In this scenario, since the file server has

  many of the same files in different directories, deduplication can identify those duplicate files and store only one copy, freeing up space on the server.

  Option A, provisioning, refers to the process of allocating and managing storage resources for a particular application or service.

  Option B, encryption, is a technique used to protect data by encoding it in such a way that only authorized users can read it.

  Option D, partitioning, is the process of dividing a physical storage device into multiple logical units, each of which can be used independently. This can be useful for organizing data or separating operating system files from user files, but it

  does not address the issue of duplicate files taking up storage space.

• Question 374:

  A server technician is placing a newly configured server into a corporate environment. The server will be used by members of the accounting department, who are currently assigned by the VLAN identified below:

  

  Which of the following IP address configurations should the technician assign to the new server so the members of the accounting group can access the server?

  A. IP address: 172.16.25.90/24 Default gateway: 172.16.25.254

  B. IP address: 172.16.25.101/16 Default gateway: 172.16.25.254

  C. IP address: 172.16.25.254/24 Default gateway: 172.16.25.1

  D. IP address: 172.16.26.101/24 Default gateway: 172.16.25.254

  Correct Answer: A

  The IP address configuration that the technician should assign to the new server so the members of the accounting group can access the server is 172.16.25.90/24 for the IP address and 172.16.25.254 for the default gateway. This configuration matches the VLAN identified in the image, which has a network address of 172.16.25.0/24 and a subnet mask of 255.255.255.0. The IP address of the server must be within the same network range as the VLAN, which is from

  172.16.25.1 to 172.16.25.254, excluding the network and broadcast addresses (172.16.25.0 and 172.16.25.255). The default gateway of the server must be the same as the VLAN, which is 172.16.25.254, to allow communication with other networks or devices outside the VLAN.

• Question 375:

  An administrator is troubleshooting a server that is rebooting and crashing. The administrator notices that the server is making sounds that are louder than usual. Upon closer inspection, the administrator discovers that the noises are coming from the front of the chassis. Which of the following is the most likely reason for this behavior?

  A. One of the fans has failed.

  B. The power supply has failed.

  C. The RAM is malfunctioning.

  D. The CPU is overheating.

  Correct Answer: A

  Explanation: A server has multiple fans inside the chassis to cool down the components and prevent overheating. If one of the fans fails, it can cause the server to reboot and crash due to thermal issues. A failed fan can also make loud noises due to friction or vibration. The administrator should check the fans and clean them from dust and debris, or replace them if they are damaged12.

• Question 376:

  A technician needs maximum power redundancy while configuring a new server rack. Which of the following should be specified? (Select two).

  A. Separate circuits

  B. Rack balancing

  C. Blanking panels

  D. High-voltage PDUs

  E. KVM placement

  F. Multiple UPSs

  Correct Answer: AF

  Explanation: Separate circuits and multiple UPSs can provide fail-safe power redundancy for a server rack. Separate circuits mean that the server rack is connected to two or more independent power sources, such as different utility lines or generators. This can prevent a single point of failure in the power supply, as if one circuit goes down, the other circuit can still provide power to the server rack1. Multiple UPSs mean that the server rack has two or more uninterruptible power supplies, which are devices that provide backup power and surge protection in case of a power outage or fluctuation. Multiple UPSs can be connected to separate circuits, or to different outlets on the same circuit, to increase the reliability and availability of power for the server rack23.

• Question 377:

  A server administrator is racking new servers in a cabinet with multiple connections from the servers to power supplies and the network. Which of the following should the administrator recommend to the organization to best address this situation?

  A. Rack balancing

  B. Cable management

  C. Blade enclosure

  D. Rail kits

  Correct Answer: B

  Cable management is the process of organizing, securing, and labeling cables in a server rack or cabinet. Cable management can help improve airflow and cooling, reduce clutter and confusion, prevent damage and interference, and enhance safety and aesthetics123. Cable management can be achieved by using various tools and accessories, such as cable trays, ties, hooks, clips, labels, ducts, and organizers12.

• Question 378:

  Which of the following distributes a load across all interfaces?

  A. Link aggregation group

  B. Most recently used algorithm

  C. Active-passive configuration

  D. Failover

  Correct Answer: A

  A link aggregation group (LAG) is a technique that combines multiple physical network interfaces into a single logical interface. This allows for the distribution of traffic across all the interfaces in the group, increasing bandwidth and

  redundancy. A LAG can use different modes to balance the load, such as address hashing, dynamic, or most recently used algorithm.

• Question 379:

  An administrator is working on improving the security of a new domain controller. A report indicates several open ports on the server. Which of the following ports should the administrator disable?

  A. 135

  B. 636

  C. 3268

  D. 3389

  Correct Answer: D

  Explanation: The port that should be disabled on the firewall is port 3389. Port 3389 is used by Remote Desktop Protocol (RDP), which is a protocol that allows remote access and controlof a Windows system through a graphical user interface. RDP can pose a security risk if it is not properly configured or secured, as it can expose the system to unauthorized or malicious access from external sources. Therefore, port 3389 should be disabled on the firewall unless it is needed for legitimate purposes.

• Question 380:

  An administrator is deploying a new secure web server. The only administration method that is permitted is to connect via RDP. Which of the following ports should be allowed? (Select two).

  A. 53

  B. 80

  C. 389

  D. 443

  E. 445

  F. 3389

  G. 8080

  Correct Answer: DF

  Port 443 is used for HTTPS, which is a secure version of HTTP that encrypts the data between the web server and the client. Port 3389 is used for RDP, which is a protocol that allows remote desktop connections to a server. These ports

  should be allowed for a secure web server that can be administered via RDP.
