VCP-VVF Troubleshoot And Optimize Practice Question
An administrator is troubleshooting a vSphere HA cluster where virtual machines failed to restart after a simulated host failure. Which TWO cluster configurations should the administrator verify? (Choose two.)
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
✓
Cluster network heartbeating and datastore heartbeat configurations.
When VMs fail to restart during an HA event, admission control settings (which might block power-ons if cluster capacity is insufficient) and network isolation responses or overall HA configuration are key factors to verify.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
vSphere Lifecycle Manager desired state compliance images.
Why it's wrong here
vLCM manages software and firmware patching, not HA restart logic.
- ✗
Storage I/O Control threshold latencies.
Why it's wrong here
SIOC manages storage I/O queues, not VM failover restarts.
- ✓
Cluster network heartbeating and datastore heartbeat configurations.
Why this is correct
If heartbeating is misconfigured or network partitions occur without datastore heartbeats configured, failure detection fails.
- ✗
Enhanced vMotion Compatibility (EVC) CPU baseline levels.
Why it's wrong here
EVC governs CPU features for vMotion, not HA restart capabilities.
- ✓
vSphere HA Admission Control capacity limits and resource reservations.
Why this is correct
If admission control is too restrictive and resource capacity is insufficient, HA will refuse to restart VMs to protect failover guarantees.
