최신 220-1201 무료덤프 - CompTIA A+ Certification Exam: Core 1
A customer built a computer for gaming, sourcing individual components and then assembling the system.
The OS starts up, but within a few minutes the machine locks up. The customer brought the computer to a technician to diagnose the issue.

정답:
Explanation:
correct
answer is "Overclocking" and "Reduce CPU Clock speed" CPU is at 4.5 Ghz when normal is 3.2 Ghz.
Overclocking too much can cause freezes, and this is a gaming computer sothe user probably took it too far.

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.
If at any time you would like to bring back the initial state of the simulation, please click the Reset All button.

정답:
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.
