HashiCorp Certified - Vault Associate Course - How Vault Works

The video uses a hotel analogy to explain how Vault operates. It describes Vault's interfaces (CLI, API, UI) as different entrances to a hotel, each suited for specific interactions. The process of authentication in Vault is likened to checking into a hotel, where a token acts as a room key, granting access to various Vault paths and capabilities. The video also covers how applications interact with Vault using tokens, emphasizing the importance of token validation and access control.

Explain the concept of TTL in relation to tokens in Vault. How does it compare to the validity of a hotel key card?

What happens if a token provided to Vault is expired or lacks permission for a requested path?

How does an application use a token to access data within Vault without needing to authenticate again?
