Comprehensive and Detailed in Depth

After successful authentication, the CLI and UI interfaces in Vault automatically assume the token for

subsequent requests, simplifying user interaction. The HashiCorp Vault documentation states: "After

authenticating, the UI and CLI automatically assume the token for all subsequent requests. The API,

however, requires the user to extract the token from the server response after authenticating in

order to send with subsequent requests." This is facilitated by Vault’s token helper mechanism for CLI

and session management in the UI.

The documentation under "Token Helper" explains: "The Vault CLI uses a token helper to store the

token locally after login (e.g., vault login), and future commands automatically use this token without

requiring it to be specified each time." Similarly, the UI stores the token in the browser session post-

login. In contrast, the API requires explicit inclusion of the token in each request header (e.g., X-

Vault-Token), making manual token management necessary. Thus, A (CLI) and C (UI) are correct.
