VCP-VVF Troubleshoot And Optimize Practice Question
An administrator is troubleshooting an issue where virtual machines on a vSphere Distributed Switch (vDS) lose connectivity intermittently after a network team changes physical switch configurations. Which vDS feature can help detect and diagnose VLAN or MTU misconfigurations between the ESXi host uplinks and the physical switch?
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
✓
vDS Health Check (MTU and VLAN configuration verification)
vSphere Health Check (specifically VLAN and MTU health checks) validates that the VLAN IDs and MTU settings configured on the vDS match the physical switch port settings.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
vDS Health Check (MTU and VLAN configuration verification)
Why this is correct
vDS Health Check tests MTU (ping sweeps with large packets) and VLAN trunking consistency between ESXi uplinks and physical switches.
- ✗
Storage I/O Control (SIOC)
Why it's wrong here
SIOC manages storage latency and queue depths.
- ✗
vSphere HA Datastore Heartbeating
Why it's wrong here
Datastore heartbeating handles HA failure detection, not network switch configuration validation.
- ✗
Enhanced vMotion Compatibility (EVC)
Why it's wrong here
EVC ensures CPU feature compatibility, unrelated to network configuration.
