A Vault operator is troubleshooting an HA cluster where the active node is not forwarding requests to standby nodes. The operator runs 'vault status' on a standby node and sees 'HA enabled: false'. What is the most likely cause?

The api_addr is not set on the standby node.

The standby node is not connected to the network.

The storage backend does not support HA.

The standby node is not unsealed.

A Vault HA cluster uses Consul for storage. The Consul cluster has three nodes, and one Consul node fails. What is the impact on the Vault cluster?

The Vault cluster shuts down to prevent data loss.

The Vault cluster continues to operate normally because Consul can tolerate the loss of one node.

The Vault cluster becomes read-only because it cannot reach a quorum.

The Vault cluster fails over to a standby node.

Which configuration parameter in the Vault server config enables HA mode?

api_addr = "https://vault.example.com:8200"

What capability must a storage backend provide for Vault to support HA leader election?

Distributed locking and shared state

A Vault HA cluster is configured with three nodes. The operator wants to ensure that clients can always reach the active node, even if they connect to a standby node. They have set api_addr on each node to the node's own IP address. What else must be configured to ensure forwarding works?

The cluster_addr on each node to enable inter-node communication.

TLS certificates on each node for secure communication.

A load balancer in front of the cluster to distribute traffic.

The ha_enabled parameter set to true on each node.
