   A large e-commerce platform uses Vault to issue short-lived tokens to millions of IoT devices that need to read a configuration secret every hour. The platform currently uses service tokens, and the Vault storage backend is growing rapidly, causing performance degradation. The team wants to reduce storage overhead while maintaining the ability to issue tokens at high throughput. What should they do?

   • AMove to a different storage backend that supports more tokens.
   • BUse periodic service tokens with a short period to allow automatic renewal.
   • CSwitch to batch tokens for the IoT devices, as they are stateless and do not consume storage.
   • DIncrease the TTL of the service tokens to reduce the frequency of token issuance.

   A Vault administrator is tuning the cluster for performance. They notice that token validation is a bottleneck. Which change would most directly reduce the validation overhead?

   • AUpgrade the storage backend to a faster one.
   • BUse a caching layer for service token validation.
   • CSwitch to batch tokens, which are validated using a local signature check.
   • DIncrease the TTL of service tokens to reduce validation frequency.

   What is a key difference between batch tokens and normal service tokens in Vault?

   • ABatch tokens are stateless and not stored in Vault, while service tokens are stored and tracked.
   • BBatch tokens are always renewable, while service tokens are not renewable.
   • CBatch tokens are stored in Vault's storage backend, while service tokens are not.
   • DBatch tokens are tied to a specific IP address, while service tokens are not.

   A security auditor is reviewing the use of batch tokens in a production environment. They ask: 'What happens if a batch token is compromised before its TTL expires?' What is the correct response?

   • AThe token can be invalidated by restarting the Vault server.
   • BThe token can be revoked immediately to prevent further use.
   • CThe token remains valid until its TTL expires, so the TTL should be short.
   • DThe token can be disabled by updating the policy.
