2V0-620 Question #114: Real Exam Question with Answer & Explanation

The correct answer is C: Disable HA before enabling Virtual SAN. When enabling VSAN on an existing cluster with HA configured, HA must be disabled first because enabling VSAN restructures the storage layer that HA depends on for datastore heartbeating.

Question

What is a requirement when enabling a Virtual SAN cluster in an existing High Availability (HA) and Distributed Resource Scheduler (DRS) Cluster?

Options

ADisable DRS and HA before enabling Virtual SAN
BEnable DRS before enabling Virtual SAN
CDisable HA before enabling Virtual SAN
DEnable Storage DRS before enabling Virtual SAN

Explanation

When enabling VSAN on an existing cluster with HA configured, HA must be disabled first because enabling VSAN restructures the storage layer that HA depends on for datastore heartbeating.

Common mistakes.

A. DRS does not conflict with enabling VSAN and does not need to be disabled; only HA must be turned off prior to VSAN enablement.
B. DRS has no prerequisite relationship to VSAN and does not need to be enabled beforehand; it is an independent cluster scheduling feature.
D. Storage DRS is a separate feature for storage load balancing and has no prerequisite or dependency relationship with enabling VSAN.

Concept tested. VSAN enablement prerequisite with existing HA cluster
