• Question 13:

  A technician needs to replace two RAID controllers on a database server as part of an upgrade. The server has six external storage arrays and eight internal disks that are controlled by the two RAID controllers. The technician completes the replacement and powers the systems back on, but the server OS detects several missing disks in the configuration.

  Which of the following steps should the technician take first to resolve this issue?

  A. Reboot to the RAID controller BIOS and rescan for attached disks and arrays
  B. Start the motherboard UEFI and confirm the RAID controller start order is correct
  C. Turn off the external arrays and reboot the server to redetect the internal disks first
  D. Turn off all components and confirm all external and internal cables before rebooting
  A. Reboot to the RAID controller BIOS and rescan for attached disks and arrays

  ---

  Explanation

  When new RAID controllers are installed and disks go missing, the first logical step is toreboot to the RAID controller BIOS and rescan for attached disks and arrays (Answer A). This will allow the RAID controller to detect the connected drives

  and rebuild the RAID configuration as expected.

  Rebooting to RAID controller BIOS (Answer A):This step ensures that all the attached disks and arrays are properly detected and mapped to the RAID configuration. Checking UEFI settings (Option B):This might be useful later, but initially,

  the RAID controller BIOS should be checked first to verify disk detection.

  Turning off external arrays (Option C):While this could be helpful in some scenarios, it's not the most efficient first step.

  Checking cables (Option D):This could be necessary, but since the controllers were just replaced, software/BIOS configurations should be checked first.

• Question 14:

  An administrator is able to ping the default gateway and internet sites byname from a file server. The file server is not able to ping the print server by name. The administrator is able to ping the file server from the print server by both IP address and computer name. When initiating an initiating from the file server for the print server, a different IP address is returned, which of the following is MOST Likely the cause?

  A. A firewall blockingthe ICMP echo reply.
  B. The DHCP scope option is incorrect
  C. The DNS entriesforthe print server are incorrect.
  D. The hosts file misconfigured.
  D. The hosts file misconfigured.

  ---

  Explanation

  The hosts file is a file that maps hostnames to IP addresses on a server or a computer. It can be used to override or supplement the DNS (Domain Name System) resolution for certain hosts or domains. If the hosts file is misconfigured, it may return a different IP address for a hostname than the one registered in the DNS server, causing connectivity issues or errors. Verified

• Question 15:

  A server room with many racks of servers is managed remotely with occasional on-site support. Which of the following would be the MOST cost-effective option to administer and troubleshoot network problems locally on the servers?

  A. Management port
  B. Crash cart
  C. IP KVM
  D. KVM
  D. KVM

  ---

  Explanation

  Management port - irrelevant choice.

  Crash cart - if you on-site support occasionally, not worth to have crash cart.

  IP KVM - this connection type use for remote drive access, remote console access, OOB and but more cost.

  KVM - local access, less cost

• Question 16:

  Which of the following asset management documents is used to identify the location of a server within a data center?

  A. Infrastructure diagram
  B. Workflow diagram
  C. Rack layout
  D. Service manual
  C. Rack layout

  ---

  Explanation

• Question 17:

  Hosting data in different regional locations but not moving it for long periods of time describes:

  A. a cold site.
  B. data at rest.
  C. on-site retention.
  D. off-site storage.
  B. data at rest.

  ---

  Explanation

  The term that describes hosting data in different regional locations but not moving it for long periods of time is "data at rest".

  Data at rest refers to data that is not actively being used or transmitted, but is instead stored in a particular location or on a particular device. This can include data that is stored on hard drives, flash drives, or other storage media, as well as

  data that is stored in the cloud or on remote servers.

  Option A, a cold site, refers to a backup facility that is not operational until a disaster occurs and is typically used for disaster recovery purposes.

  Option C, on-site retention, refers to the practice of storing data on site, typically for regulatory or compliance purposes.

  Option D, off-site storage, refers to the practice of storing data in a location other than the primary data center, typically for backup or disaster recovery purposes.

• Question 18:

  A database developer recently requested a 4TB SATA drive utilizing spinning disks be added to an existing system for a new, heavily used database. The storage administrator turned down the request after reviewing it.

  Which of the following is the most likely reason the administrator did that?

  A. The drive is not capable of deduplication.
  B. The drive would have slow I/O performance.
  C. The drive cannot use NTFS.
  D. The drive is not compatible with the server OS.
  B. The drive would have slow I/O performance.

  ---

  Explanation

  A heavily used database requires high I/O (Input/Output) performance for frequent transactions. Considering the storage options:

  The drive is not capable of deduplication (A): Deduplication is useful for saving storage space, but it is not a primary concern for database performance. The drive would have slow I/O performance (B): Traditional spinning disk SATA drives

  have significantly lower IOPS (Input/Output Operations Per Second) compared to SSDs or enterprise-level NVMe storage. A high-traffic database benefits from low-latency, high-throughput storage, which SATA HDDs do not provide. The

  drive cannot use NTFS (C): SATA drives can use NTFS, so this is incorrect. The drive is not compatible with the server OS (D): Most modern operating systems support SATA drives. Because SATA spinning disks cannot handle high

  transaction loads efficiently, the administrator likely rejected the request due to poor I/O performance.

• Question 19:

  An administrator is setting up a new employee's read/write access to a document on the file server. Currently, the user can open the file, but edits cannot be saved.

  Which of the following should the administrator do so the user can save the updated file while maintaining least-privilege access?

  A. Give the user "read and execute" rights to the file.
  B. Give the user "modify" rights to the file.
  C. Give the user "list folder contents" rights to the folder.
  D. Give the user "full control" rights to the folder.
  B. Give the user "modify" rights to the file.

  ---

  Explanation

  To enable a user to both read and write to a file, the administrator needs to provide "modify" rights. This permission level allows the user not only to open and view the file (read) but also to make changes and save those changes back to the file (write). "Read and execute" rights would allow the user to open and run the file but not make any changes. "List folder contents" rights would enable the user to view the files within a folder but not make changes to them. "Full control" rights would provide the user with complete control over the file, including the ability to change permissions and delete the file, which exceeds the principle of least-privilege access necessary for this task.

• Question 20:

  Which of the following DR testing scenarios is described as verbally walking through each step of the DR plan in the context of a meeting?

  A. Live failover
  B. Simulated failover
  C. Asynchronous
  D. Tabletop
  D. Tabletop

  ---

  Explanation

  Tabletop is the DR testing scenario that is described as verbally walking through each step of the DR plan in the context of a meeting. This type of test is often used to evaluate the effectiveness of a disaster recovery plan and to identify areas for improvement. It involves a group of stakeholders discussing hypothetical scenarios and the steps they would take to respond to them, without actually executing any of the recovery procedures.
