VCP-DCV vSphere Performance and Scaling Practice Question
A company has a cluster of 4 ESXi hosts. They want to ensure that virtual machines are automatically distributed evenly across hosts based on CPU and memory load. Which feature should be enabled on the cluster?
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
✓
vSphere DRS
DRS (Distributed Resource Scheduler) automatically balances VM loads based on resource usage. HA provides high availability, FT provides fault tolerance, and DPM manages host power.
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 HA
Why it's wrong here
vSphere HA restarts VMs on surviving hosts after a host failure; it does not continuously balance CPU and memory load across healthy hosts. It would be correct where the requirement is automated recovery from host outages rather than ongoing distribution of running workloads.
- ✗
Fault Tolerance
Why it's wrong here
Fault Tolerance maintains a live shadow copy of a single VM on another host for continuous availability; it does not redistribute VMs across the cluster. It would be the right feature where an individual workload needs zero-downtime protection against host failure, not balanced resource usage.
- ✓
vSphere DRS
Why this is correct
vSphere DRS continuously balances VM placement across hosts by migrating workloads with vMotion based on CPU and memory demand, directly satisfying the requirement for automatic even distribution. Enabling it on the cluster activates initial placement plus ongoing load-balancing, which HA alone cannot provide.
- ✗
Distributed Power Management
Why it's wrong here
Distributed Power Management consolidates workloads onto fewer hosts during low demand and powers off the rest; it responds to cluster-wide power consumption, not per-VM load balancing. It would be correct where the goal is reducing power draw, not even CPU and memory distribution.

Same concept, more angles
1 more way this is tested on VCP-DCV
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A vSphere cluster has DRS enabled and hosts with unbalanced resource usage. Which DRS feature automatically migrates VMs to balance CPU and memory loads across hosts?
easy- A.High Availability (HA)
- ✓ B.Distributed Resource Scheduler (DRS)
- C.Enhanced vMotion Compatibility (EVC)
- D.Storage I/O Control (SIOC)
Why B: DRS (Distributed Resource Scheduler) uses vMotion to migrate VMs based on resource utilization thresholds, balancing workloads across hosts. HA provides failover, EVC ensures compatibility, and SIOC manages storage I/O.
