VMware App Volumes (VCP-AM 2019) — Question 69

What could cause a vSAN stretched cluster to fail?

Answer options

• A. 5ms round-trip time (RTT) between data sites
• B. blocked UDP ports on the firewall between data sites
• C. Layer 3 communication from the data sites to the witness site
• D. static routes between the witness site and data site

Correct answer: B

Explanation

The correct answer is B because blocked UDP ports can prevent necessary communication between the data sites, which is essential for the vSAN stretched cluster's operation. Options A, C, and D do not inherently cause failure; for instance, a 5ms RTT is acceptable, and Layer 3 communication along with static routes can be configured correctly without leading to issues.
