An administrator wants to form an HA cluster using the FGCP protocol. Which two requirements must the administrator ensure both members fulfill? (Choose two.)

Question

Options

• AThey must have the same HA group ID.
• BThey must have the heartbeat interfaces in the same subnet.
• CThey must have the same number of configured VDOMs.
• DThey must have the same hard drive configuration.

• A
  89% (41)
• B
  7% (3)
• C
  4% (2)

Explanation

A (same HA group ID) is required because FGCP uses the group ID to identify cluster members - units with different group IDs will not recognize each other as peers and will never form a cluster. D (same hard drive configuration) is required because FGCP synchronizes logs and configuration data across members, and mismatched drive configurations break that synchronization, making the cluster unable to form or operate correctly.

B is wrong because FGCP heartbeat communication operates at Layer 2 using multicast, so there is no subnet-matching requirement for heartbeat interfaces - they simply need to be directly reachable between the two units. C is wrong because VDOM configuration is synchronized after the cluster forms, not a prerequisite for formation; you don't need matching VDOM counts going in.

Memory tip: Think "ID and Drive to Stay Alive" - the Group ID authenticates membership, and the Drive configuration enables the data sync that keeps both members viable. Everything else (VDOMs, subnets) is either handled post-formation or not a hard FGCP requirement.
