VMware Workspace ONE Advanced (VCAP-DTM Design) — Question 11

An architect is working on a physical desktop replacement using Horizon View.
The architect gathered this information from the customer:
✑ There are currently 500 physical desktops, all with traditional spinning hard drives.
✑ Each desktop peaks at 75 IOPS multiple times during the day.
✑ The average read/write ratio is 30% reads, 70% writes.
The architect decided to size the vSAN cluster to handle the workload using FTT=1 and Fault Tolerance Method of RAID-1.
Using only the information provided, what are the total calculated IOPS required for the vSAN cluster?

Answer options

Correct answer: A

Explanation

The total IOPS required is calculated by multiplying the number of desktops (500) by the peak IOPS per desktop (75), resulting in 37,500 IOPS. Since FTT=1 and RAID-1 is used, the total IOPS requirement is doubled to account for redundancy, leading to a total of 75,000 IOPS. The other options do not account for the necessary fault tolerance or miscalculate the total IOPS needed.
