Domain overview
This domain covers how Vault Enterprise scales reads and writes across clusters using Performance Replication, Performance Standby nodes, and Integrated Storage. Questions are scenario-based: you must choose the correct replication mode, diagnose replication lag, and reason about which nodes serve which requests and how secondaries affect throughput.
Exam objectives
Selecting Performance Replication versus DR Replication for read scaling and local token/lease handling
Configuring Performance Standby nodes with `vault operator` and understanding their request-forwarding behavior
Diagnosing replication lag and tuning secondary clusters to reduce it
Using Integrated Storage, Raft, and `vault operator raft` commands to inspect cluster performance
Assuming Performance Replication also provides automatic failover; only DR Replication promotes a secondary to primary.
Believing Performance Standby nodes handle writes locally; they forward writes to the active node.
Treating all secondaries as identical; their hardware, network latency, and write volume directly affect lag and throughput.

Which component is responsible for receiving and responding to read requests in a Performance Standby configuration?
2Your organization requires fine-grained control over what data is synchronized to a specific Performance Secondary cluster to reduce storage overhead. Which feature should you implement?
3You are using Batch tokens in your environment to improve performance. A developer asks why their Batch token cannot be revoked individually. What is the primary reason?
4An application is configured to use a Batch token. Which of the following operations will fail when using a Batch token?
5When utilizing performance replication, your Vault cluster experiences high replication lag between the primary and secondary sites. Which action would most effectively reduce this lag?
6You are managing a multi-region Vault deployment with Performance Replication. You notice that a specific secret engine mount is not being replicated to the secondary site. What should you check?
7What is the benefit of using Performance Replication over standard DR Replication?
8Which THREE factors influence the performance of a Performance Secondary cluster?
9When configuring path filters for performance replication, what is the effect of using an 'exclude' filter on a path?
10Which TWO statements are true about the relationship between Performance Standby nodes and Performance Replication?
11You are preparing to add a new Performance Secondary cluster to an existing Vault Enterprise Performance Replication setup. The primary cluster uses integrated storage. To ensure that the new secondary can successfully receive replication data and serve read requests, which step must you take before enabling replication on the secondary?
12A Vault Enterprise cluster is running with three nodes. The active node is handling both reads and writes, and the two standby nodes are idle. You want to scale read performance by allowing the standby nodes to serve read requests while maintaining the same high availability and data consistency guarantees. Which configuration should you enable?
13A Vault Enterprise cluster is configured with Performance Replication to a secondary cluster. The secondary cluster is in a different region and is used for disaster recovery and read scaling. You notice that the secondary cluster is experiencing high replication lag, and some read requests return stale data. Which factor is most likely causing the lag?
14You are using Vault Enterprise with Performance Replication. The primary cluster is in us-east-1, and a secondary cluster is in eu-west-1. You need to ensure that the secondary cluster can continue to serve read requests even if the primary cluster becomes unavailable. Which statement describes the behavior of the secondary cluster in this scenario?
15You are the Vault operator for a financial services company. Your Vault Enterprise cluster runs Integrated Storage and is approaching its maximum write throughput during peak trading hours. You need to increase write scalability without changing the client API or adding a separate Disaster Recovery cluster. Which action should you take?
16You manage a Vault Enterprise cluster with Performance Replication enabled. The primary cluster is in us-east-1 and a secondary cluster is in eu-west-1. Clients in eu-west-1 are experiencing high read latency even though replication lag is consistently low. You have already verified that the secondary is healthy and has Performance Standby nodes. What is the most likely cause?
17You are scaling a Vault Enterprise cluster to handle a high volume of database credential generation. You configure the database secrets engine with a maximum open connections setting of 100 and a maximum idle connections setting of 20. After a few hours, you notice that the number of open connections to the database frequently reaches 100 and stays there, even when request rates are moderate. You want to reduce the connection churn and improve performance without changing the maximum open connections. What should you do?
18You are configuring a Vault Enterprise cluster with integrated storage to scale for a high-read workload. You plan to add performance standby nodes. Which two statements accurately describe how performance standbys affect scaling and request handling? (Choose two.)
19You are evaluating whether to use a Batch token for a high-throughput application that performs frequent secret reads. The application runs on a container platform and can handle token renewals. What is a key characteristic of Batch tokens that affects performance?
20You are troubleshooting performance issues in a Vault Enterprise cluster that uses Integrated Storage. You notice that the Raft leader is frequently changing, causing disruptions in service. Which of the following is the most likely cause of this instability?
21You operate a Vault Enterprise Performance Primary with a Performance Secondary. The secondary is used for read-only workloads in a disaster recovery site. During a planned maintenance window, the primary is taken offline. Which statement describes the expected behavior of the secondary?
22You are deploying a Vault Enterprise cluster with Integrated Storage and want to ensure high availability. The cluster will have five nodes. What is the minimum number of nodes that must be active and healthy to maintain quorum and allow write operations?
Be able to choose Performance Replication for read scaling, explain how Performance Standby nodes forward writes, and diagnose lag using replication status and Raft metrics. The key is knowing which cluster owns writes and which nodes can serve reads locally.
