VCP-VVF IT Architectures Technologies Standards Practice Question
An enterprise architect is designing a multi-site vSphere Foundation 9.0 environment with stretched clusters. When configuring vSAN stretched cluster witness traffic, what is the architectural recommendation regarding the witness network connection?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Ensure the witness network link meets minimum bandwidth requirements and maintains an RTT latency of 100 milliseconds or less.
The vSAN witness traffic must traverse a reliable, lower-latency IP network connection to the primary cluster nodes, with specific minimum bandwidth and latency thresholds (typically < 100ms RTT for witness traffic, < 5ms for data sites).
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Ensure the witness network link meets minimum bandwidth requirements and maintains an RTT latency of 100 milliseconds or less.
Why this is correct
Correct. Witness traffic requires low latency (<100ms RTT) and adequate bandwidth depending on component counts.
- ✗
Configure the witness node to run on the exact same physical ESXi host as the primary storage controller.
Why it's wrong here
The witness node must reside on a separate site/failure domain; putting it on the primary host defeats its purpose.
- ✗
Route witness traffic exclusively through unencrypted public dial-up modems.
Why it's wrong here
Modems are obsolete and lack required bandwidth and stability.
- ✗
Disable all IP keepalive heartbeats on the witness vmkernel adapter.
Why it's wrong here
Disabling heartbeats would cause the cluster to lose quorum visibility.
