A PowerEdge server is configured with a hardware RAID controller that has a battery-backed write cache. The administrator is considering changing the write cache policy from Write-Back to Write-Through to improve data safety. What is the most likely impact of this change on write performance?

Write performance will improve because the cache is no longer used.

Write performance will increase because the cache is bypassed, reducing latency.

Write performance will decrease because the controller must wait for the write to be committed to the drives.

Write performance will remain the same because the cache is only used for reads.

Which component in a PowerEdge server is responsible for managing the flow of data between the CPU and physical disk drives?

Storage controller (RAID controller)

Which strategy can help optimize throughput in a PowerEdge server that experiences high network traffic?

Using a network interface card with TCP/IP offload engine (TOE)

Increasing the number of cooling fans
