Which of the following statements describe the CLI command below?
S vault login -method-1dap username-mitche11h
Options:
A.
Generates a token which is response wrapped
B.
You will be prompted to enter the password
C.
By default the generated token is valid for 24 hours
D.
Fails because the password is not provided
Answer:
A
Explanation:
Explanation:
The CLI command vault login -method ldap username=mitchellh generates a token that is response wrapped. This means that the token contains a base64-encoded response wrapper, which is a JSON object that contains information about the token, such as its policies, metadata, and expiration time. The response wrapper is used to verify the authenticity and integrity of the token, and to prevent replay attacks. The response wrapper also allows Vault to automatically renew the token when it expires, or to revoke it if it is compromised. The -method ldap option specifies that the authentication method is LDAP, which requires a username andpassword to be provided. The username mitchellh is an example of an LDAP user name, and the password will be hidden when entered.

Question 17
Which of these are a benefit of using the Vault Agent?
Options:
A.
Vault Agent allows for centralized configuration of application secrets engines
B.
Vault Agent will auto-discover which authentication mechanism to use
C.
Vault Agent will enforce minimum levels of encryption an application can use
D.
Vault Agent will manage the lifecycle of cached tokens and leases automatically
Answer:
D
Explanation:
Explanation:
Vault Agent is a client daemon that provides the following features:
Auto-Auth - Automatically authenticate to Vault and manage the token renewal process for locally-retrieved dynamic secrets.
API Proxy - Allows Vault Agent to act as a proxy for Vault’s API, optionally using (or forcing the use of) the Auto-Auth token.
Caching - Allows client-side caching of responses containing newly created tokens and responses containing leased secrets generated off of these newly created tokens. The agent also manages the renewals of the cached tokens and leases.
Templating - Allows rendering of user-supplied templates by Vault Agent, using the token generated by the Auto-Auth step.
Process Supervisor Mode - Runs a child process with Vault secrets injected as environment variables.
One of the benefits of using the Vault Agent is that it will manage the lifecycle of cached tokens and leases automatically. This means that the agent will handle the token renewal and revocation logic, as well as the lease renewal and revocation logic for the secrets that are cached by the agent. This reduces the burden on the application developers and operators, and ensures that the tokens and secrets are always valid and up-to-date.
