Start Fault Tolerant Vault Environments PracticeIn a Performance Replication setup, a secondary cluster is experiencing high latency for read requests. Which action should you take to verify if the requests are being routed correctly?
Explanation: The sys/metrics endpoint exposes internal telemetry, including counters for performance standby requests, which reveal whether read requests are being routed to the secondary cluster's performance standbys as intended. Checking this metric confirms routing behavior and helps diagnose latency caused by misrouted or overloaded standbys. It is the correct diagnostic step before changing configuration.
You have a Performance Replication setup. A client sends a write request to a performance standby node. What happens to this request?
Explanation: In a Vault Enterprise Performance Replication topology, a performance standby node is a read-only replica that maintains its own storage backend and can serve reads locally, but it cannot process writes. When a client sends a write request to a performance standby, Vault transparently forwards the request over the replication connection to the active node in the primary cluster, which performs the write and returns the response. This forwarding is automatic and transparent to the client, so no error is returned.
When migrating from an external storage backend to Raft, which command is used to capture the current state of the cluster for migration?
Explanation: The `vault operator raft snapshot save` command captures a point-in-time snapshot of the Raft cluster's state, including all Vault data and configuration. This snapshot is essential for migrating from an external storage backend (like Consul or file) to Raft, as it allows you to restore the data into the new Raft storage. The command is specifically designed for Raft integrated storage and produces a consistent backup that can be later restored using `vault operator raft snapshot restore`.
You are configuring a Vault cluster for high availability using Consul as the storage backend. During a network partition, the standby nodes cannot reach the leader node. What must occur for a new leader to be elected?
Explanation: With Consul as the storage backend, Vault HA leader election relies on Consul's session mechanism: the active node holds a Consul session lock, and if the standby nodes cannot reach the leader, the Consul agent expires the leader's session, releasing the lock and triggering an election among standbys. The node that acquires the lock becomes the new active node.
You are troubleshooting a sync issue in Performance Replication. The logs indicate 'replication lag'. Which parameter should you review to ensure optimal data synchronization between clusters?
Explanation: While there isn't a single 'lag' parameter, review the 'replication_buffer_size' or network throughput limits between clusters as part of diagnosing synchronization bottlenecks.
