   How do performance standby nodes contribute to high availability?

   • AThey participate in leader election and can become the active node
   • BThey automatically take over write operations if the active node becomes unreachable
   • CThey provide additional read capacity that remains available if the active node fails
   • DThey serve as a backup that can be promoted manually in an emergency

   A global SaaS provider has Vault Enterprise deployed in three regions: US-East, EU-West, and AP-Southeast. Each region has a performance standby node. Applications in each region read secrets and tokens frequently, but writes are rare and originate only from the US-East region. The team wants to minimize latency for read operations in each region. What is the primary benefit of this deployment?

   • AThe active node is automatically replicated to each region, ensuring data locality for all operations.
   • BWrite requests are processed locally in each region, reducing the load on the active node.
   • CEach region can elect its own active node, providing independent failover.
   • DRead requests are served locally in each region, reducing network round-trip time and improving latency.

   A security team manages Vault Enterprise for a large organization. They notice that the active node's CPU is pegged at 95% during peak hours, primarily due to token validation requests. Write operations are minimal. The team wants to reduce the CPU load on the active node without changing the failover configuration. What is the best approach?

   • AAdd performance standby nodes and route token validation requests to them.
   • BAdd standard standby nodes and route token validation requests to them.
   • CMove token validation to a separate Vault cluster to isolate the workload.
   • DIncrease the TTL of tokens to reduce the frequency of validation requests.

   A large e-commerce platform runs Vault Enterprise in a single region with a cluster of 5 nodes. The platform's authentication service performs approximately 40,000 token lookups per second, while writes (token creation, lease renewal) occur at only 200 operations per second. The current active node's CPU is consistently at 85% during peak traffic, causing latency spikes. The team needs to reduce latency for read-heavy workloads without adding complexity around leader election. What should the team configure?

   • AConfigure the existing standby nodes to forward all read requests to the active node to balance the load.
   • BAdd 3 additional active nodes to the cluster and configure the load balancer to round-robin all requests across the 8 nodes.
   • CAdd 3 performance standby nodes to the cluster and configure the load balancer to distribute read requests across all nodes.
   • DIncrease the storage backend's performance tier and keep the current 5-node cluster unchanged.
