Which two options are requirements for enabling High Availability on a vRealize Operations cluster? (Choose two.)

Question

Options

• AOnly the Data nodes must be online.
• BThe cluster must have at least one Primary node.
• COnly the Primary node must be online.
• DThe cluster must have at least one Data node.
• EThe cluster must have at least two Data nodes.

• A
  3% (1)
• B
  94% (30)
• E
  3% (1)

Explanation

Enabling HA in vRealize Operations requires both a functioning Primary node (B) - which coordinates the cluster and hosts the management stack - and at least one Data node (D), which acts as the HA replica that can take over if the Primary fails. Together, these two form the minimum viable pair for HA to be configured and activated.

Why the distractors fail:

• A is wrong because requiring only Data nodes ignores the mandatory Primary node role.
• C is wrong because a lone Primary node has nothing to fail over to - you need a Data node as the standby replica.
• E is too strict; HA requires a minimum of one Data node, not two (two Data nodes would be needed for a larger cluster, but it's not the HA prerequisite).

Memory tip: Think "P + D = HA" - one Primary and at least one Data node. If either piece of that pair is missing, HA cannot be enabled.
