A company is deploying Vault in a high availability (HA) configuration with three nodes. The primary node handles all requests, and the standby nodes are ready to take over if the primary fails. The administrator wants to ensure that standby nodes can serve read requests to reduce load on the primary. Which configuration should be used?

Enable HA mode on all nodes but do not configure performance standby.

Enable performance standby on the standby nodes by setting 'performance_standby = true' in the Vault configuration.

Set 'disable_clustering = true' on the standby nodes.

Configure the standby nodes to use a different storage backend than the primary.

What is the primary purpose of restricting network access to Vault using security groups or firewall rules?

To enable Vault to use a different storage backend

To increase the speed of API requests by reducing network hops

To allow Vault to automatically unseal itself

To minimize the attack surface by allowing only trusted clients to reach the Vault API

What is the primary purpose of configuring TLS for a Vault server?

To prevent unauthorized access to the Vault API

To enable the Vault server to act as a certificate authority

To authenticate the client to the server using certificates

To encrypt communication between Vault clients and the server

A junior administrator starts Vault with the command 'vault server -dev' to test a new authentication method. The security team notices this and asks the administrator to run Vault in production mode. Which of the following is the most important change the administrator must make?

Use the dev server but change the storage backend to file by editing the configuration file.

Stop the dev server and start Vault with a proper configuration file that specifies a storage backend, listener, and seal settings.

Restart the dev server with the -dev-root-token-id flag to set a known root token.

Keep the dev server running but add a root token to the configuration file for easier access.

Which configuration option enables high availability in Vault?

`replication = true` in the storage stanza

`high_availability = true` in the listener stanza

`ha_enabled = true` in the storage stanza
