Which statement is true about running both DRS and VMware HA (HA) on the same
cluster?

A.
There is no advantage to running these two technologies on the same cluster as they
are completely unrelated.

B.
After a host failure, HA can start virtual machines intelligently using DRS algorithms.

C.
After a host failure, HA will restart virtual machines and DRS will migrate them to
balance the workloads.

D.
This is not a recommended configuration.

Explanation:
Automating High Availability (HA) Services with VMware HA, page 4.
1. VMware VMotion enables the live migration of running virtual machines from one
physical server to another. Live migration of virtual machines enables companies to
perform hardware maintenance without scheduling downtime and disrupting business
operations. VMotion also allows the mapping of virtual machines to hosts to be
continuously and automatically optimized within clusters for maximum hardware
utilization, flexibility, and availability.
2. VMware DRS works with VMotion to provide automated resource optimization and
virtual machine placement and migration to help align available resources with
pre-defined business priorities while maximizing hardware utilization.
