VMware Workspace ONE Advanced (VCAP-DTM Design) — Question 23

An architect is asked to analyze poor performance on a Horizon VDI environment and provide recommendations on how to improve the user experience.
The architect documents:
✑ An ESXi cluster of 4 nodes using vSAN
✑ Each node has 128GB of RAM, four 500GB 10K HDD, one 200GB SSD
✑ Each desktop is configured with 4GB of RAM and 2vCPUs
✑ Each desktop has a working set of 20 GB
✑ The environment peaks at 150 concurrent desktops in use
What action can the architect recommend?

Answer options

• A. Add three additional 200GB SSD drives to each of the ESXi hosts.
• B. Add an additional 200GB SSD to each of the ESXi hosts.
• C. Reserve all RAM assigned to the virtual desktops.
• D. Increase the RAM assigned to the virtual desktops.

Correct answer: D

Explanation

The correct answer is D because increasing the RAM assigned to virtual desktops can help accommodate their working set better, improving performance for users. Options A and B focus on SSD additions which may not directly address the RAM constraints, while option C suggests reserving all RAM, which could lead to resource allocation issues and doesn't improve the performance per desktop.
