20+ practice questions focused on Access Control Configuration — one of the most tested topics on the HashiCorp Certified: Vault Operations Professional (Vault Enterprise) (Vault Enterprise) exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Access Control Configuration PracticeWhich command is used to assign an ACL policy to an existing Identity Entity?
Explanation: The 'vault write identity/entity-alias' command is used to link an alias to an entity, and policies are typically mapped via 'vault write identity/entity'.
When using Namespace-based multi-tenancy, which statement is true regarding the root namespace?
Explanation: In Vault Enterprise's namespace model, the root namespace is the top-level administrative boundary from which all child namespaces are created and inherit identity structures. Identity entities, groups, and aliases defined at the root are visible to and can be referenced by child namespaces, making the root the origin point for identity derivation. Child namespaces are logically nested under the root, and the root remains fully functional for secrets, auth methods, and policies.
Which API endpoint should you use to check if a specific policy exists in the system?
Explanation: The correct endpoint to list or check ACL policies in Vault is GET /sys/policies/acl, which returns a list of all ACL policies in the system. To check if a specific policy exists, you can issue GET /sys/policies/acl/:name, which returns the policy details or a 404 if it does not exist. This endpoint replaced the older /sys/policy endpoint in Vault 0.9+ and is the canonical way to manage ACL policies.
You are troubleshooting a policy that is not granting the expected permissions. Which tool can help you simulate the policy evaluation for a given path?
Explanation: The 'vault policy test' command is used to simulate authorization checks against a policy for a specific path and capability.
If you need to grant a group of developers access to all paths starting with 'secret/data/developers/', which HCL syntax is correct?
Explanation: In Vault ACL policies, a single asterisk (*) at the end of a path matches any characters after that prefix, so 'secret/data/developers/*' grants access to all paths beginning with 'secret/data/developers/'. This is the correct HCL syntax for prefix-based path matching in Vault policies. The KV v2 secrets engine requires the 'data/' segment in the path because that is the actual API endpoint for reading/writing secret data.
