A team uses Vault Agent to authenticate to Vault with the AWS method and writes the token to a file sink. They notice that the token file is not being updated after the token is renewed. What is the most likely cause?

The 'exit_after_auth' option is set to true, so the agent exits after the initial auth.

The token TTL is set to 0, meaning it never expires.

The sink file is mounted as read-only.

The agent is not configured with a 'renew' stanza.

A security audit reveals that Vault Agent's auto-auth token is appearing in the process list and in system logs. The agent is configured with the Kubernetes auth method. Which change would most directly prevent this exposure?

Use a sink file with restrictive permissions and ensure the agent does not log the token.

Enable the 'log_level' to 'trace' to see what is happening.

Use the 'vault agent' command with the '-log-level=error' and avoid passing secrets as command-line arguments.

Set the 'token' field in the auto-auth configuration to a placeholder.

A Vault Agent is configured with auto-auth and a file sink. The application reads the token from the sink file. The team wants to ensure the application always reads a valid token, even during a token renewal. What should they do?

Use the 'vault agent' API to retrieve the token instead of a file sink.

Use the 'token_sink' with the 'file_mode' set to 0644.

Configure the application to read the token file only once at startup.

Ensure the agent writes the new token atomically to the sink file.
