See the detailed solution in explanation below.
Explanation:
The degraded status on Server 2 indicates a RAID-5 issue, typically due to a failed or failing drive. In RAID-5 configurations, when one drive fails, the system can still operate but with reduced performance as parity data is used to rebuild missing data on-the-fly.
Recommended Replacement Drive:
To minimize performance degradation, the replacement drive should be:
SAS HDD with the same specifications (64KB stripe size, no read-ahead, and write-back policy).
Matching the configuration exactly ensures seamless integration and optimizes recovery speed in the RAID-5 array.
In RAID-5, degraded performance is expected when one drive fails, as parity data needs to rebuild missing information during each read/write process. Replacing the failed drive restores the RAID array to optimal status, reducing the load on existing drives and returning the system to normal read/write performance. The write-back policy and disabled disk cache settings are designed to reduce latency and increase efficiency, essential for handling real-time applications.
A user reports poor performance on the
application server.
INSTRUCTIONS
Click on Server 1 and Server 2 and review
the information presented in each chart to
determine which drives need to be replaced.
Select the appropriate replacement drive
that should be used, for the least
performance degradation to the server.

RAID 1, also known as disk mirroring, duplicates data identically to two drives, ensuring full redundancy if one drive fails. Because the workstation only has two drives, RAID 1 is the only RAID level that provides fault tolerance under this constraint, exactly as described in the CompTIA A+ study guide.
RAID 0 offers no redundancy, RAID 5 requires at least three drives, and RAID 10 requires at least four drives.
RAID 1 is the recommended configuration for small environments or workstations that rely on data integrity and quick recovery, matching CompTIA's guidance for redundancy in systems with limited drive availability.

Identifying changes made to the system is the next step to troubleshoot why an application no longer launches, as recent changes often cause such issues.
Why Not A (Research the symptoms): Research is broader and should come after identifying changes.
Why Not C (Determine which steps need to be performed): This comes after identifying the issue.
Why Not D (Check the vendor's website): This is a later step if further guidance is needed.
