VCP Quality Assurance & Improvement 3

Question 1

Which vSphere DRS automation level requires manual administrator approval before migrating VMs?

Accepted Answer

Manual

Answer

In Manual DRS mode, vSphere generates migration recommendations but requires administrator approval before any VM is moved.

Question 2

What is the purpose of vSphere Storage I/O Control (SIOC)?

Accepted Answer

To prioritize datastore I/O during contention

Answer

SIOC monitors datastore latency and throttles lower-priority VMs' I/O to ensure higher-priority VMs get adequate storage performance during contention.

Question 3

An administrator notices vSphere HA admission control is blocking VM power-ons. What does this indicate?

Accepted Answer

The cluster lacks resources to tolerate the configured number of host failures

Answer

HA admission control enforces resource reservations to guarantee failover capacity, blocking power-ons when insufficient resources exist.

Question 4

Which vSphere feature provides zero-downtime protection by maintaining a continuous mirror of a VM on a secondary host?

Accepted Answer

vSphere Fault Tolerance

Answer

vSphere Fault Tolerance creates a live shadow VM on a secondary host that takes over instantly if the primary host fails, providing zero RPO and RTO.

Question 5

What is the primary function of the vSphere Distributed Resource Scheduler (DRS) imbalance metric?

Accepted Answer

Quantify CPU and memory load imbalance across cluster hosts

Answer

The DRS imbalance metric measures how unevenly CPU and memory resources are distributed across cluster hosts, triggering migrations to rebalance.
