Question 1 of 30

A data center administrator is troubleshooting a storage performance issue in a Cisco Unified Computing System (UCS) environment. The administrator notices that the latency for storage I/O operations has increased significantly. After checking the storage array, the administrator finds that the average I/O size is 8 KB, and the throughput is measured at 200 MB/s. The administrator also observes that the storage system is configured with a RAID 5 setup. Given that the storage system has 5 disks, calculate the theoretical maximum throughput for the RAID 5 configuration and identify the most likely cause of the increased latency.

The theoretical maximum throughput is 400 MB/s, and the increased latency is likely due to the overhead of parity calculations in RAID 5.

The theoretical maximum throughput is 200 MB/s, and the increased latency is likely due to insufficient disk space.

The theoretical maximum throughput is 800 MB/s, and the increased latency is likely due to network congestion.

The theoretical maximum throughput is 600 MB/s, and the increased latency is likely due to a hardware failure in one of the disks.
