What is a "Lease" in Vault? - A service level agreement for enterprise cloud support - Metadata defining the validity period of a given secret - The total time required for a node to join a cluster - A backup copy of the master key shards for recovery **Hint:** Time-limited access. ### 9. How are permissions managed in Vault? - Through manual entries in an administrative ledger - Using Policies written in HashiCorp Configuration (HCL) - By modifying the local server environment variables - Using standard Linux filesystem permission bits (CHMOD) **Hint:** HCL files. ### 10. What is the "Auth Method" for Kubernetes? - Configuring static user credentials inside the pod spec - Using Kubernetes Service Account tokens to login to Vault - Scanning a physical biometric ID from the server room - Directly sharing the Vault root token with all nodes **Hint:** Connecting K8s pods to Vault. ### 11. What is the "Master Key" used for? - To authenticate every user login via the web interface - To decrypt the internal barrier and data during startup - To manage physical access to the server room hardware - To provide a global reset for all user-level passwords **Hint:** The key that protects all other keys. ### 12. What is the "PKI" Secret Engine? - A tool for managing static application passwords - A system to generate X.509 certificates on-demand - A protocol for syncing time across server clusters - A method for encrypting standard network traffic logs **Hint:** TLS/SSL management. ### 13. Which command initializes a brand-new Vault server? - `vault server -dev` (Development mode startup) - `vault operator init` (Initialize server) - `vault configuration bootstrap` (Setup utility) - `vault secret enable` (Engine activation) **Hint:** The very first command. ### 14. What happens when a Vault token expires? - It remains valid until the user logs out manually - The token and its associated access are revoked - The server automatically generates a replacement token - The associated secrets are deleted from the storage **Hint:** Immediate loss of access. ### 15. What is "Auto-unseal" in HashiCorp Vault? - A feature where Vault unseals using a local text file - Using a cloud KMS to automatically decrypt the key - A setting that keeps Vault unsealed during a restart - A method to bypass the master key requirement entirely **Hint:** Cloud-native unsealing. ### 16. What is a "Root Token" in Vault? - A token specifically for the Linux system root user - A privileged token used for initial system configuration - A token used to access the root directory of the OS - A backup file containing the entire database contents **Hint:** God-mode access. ### 17. What does "Vault Audit Logging" provide? - A visual graph of server CPU and memory utilization - A record of every request and response sent to Vault - A diagnostic check of the network latency between nodes - A list of all developers currently employed at the firm **Hint:** The record of who did what. ### 18. What is "Response Wrapping" in Vault? - A process of compressing responses to save bandwidth - A method to deliver secrets via a one-time-use token - An algorithm that encrypts the response twice over - A tool for deleting the response after it is read **Hint:** Securely passing secrets to others. ### 19. What is the "AppRole" Auth Method? - A communication protocol for application chat services - A method for machine authentication using Role and Secret IDs - A list of application roles available in the cloud console - A recruitment platform for professional cloud developers **Hint:** Machine-to-machine auth. ### 20. In Vault, what is the "Barrier"? - A physical security perimeter around the data center - The layer that encrypts all data leaving the server - A network firewall that blocks external IP addresses - A software limitation that prevents data corruption **Hint:** The encryption wall. ### 21. Which Vault engine provides temporary database credentials? - The KV Secret Engine (Static) - The Database Secret Engine (Dynamic) - The Transit Secret Engine (Crypto) - The SSH Secret Engine (Access) **Hint:** Works with SQL and NoSQL. ### 22.
