問題 #69
From the options below, select the auth methods that are better suited for machine-to-machine authentication (select five):

答案：A,C,F,G,H

解題說明：
Comprehensive and Detailed in Depth Explanation:
Machine-to-machine (M2M) auth methods in Vault enable automated systems to authenticate without human interaction. Let's assess:
* A: Kubernetes - Uses service account tokens for pods. Correct. Vault Docs Insight: "Kubernetes auth... ideal for workloads in Kubernetes clusters."
* B: GitHub - User-focused, requires human GitHub login. Incorrect. Vault Docs Insight: "GitHub auth... typically for human users."
* C: TLS - Certificate-based, perfect for M2M. Correct. Vault Docs Insight: "TLS auth uses certificates... suited for machine authentication."
* D: Token - Pre-generated tokens for automation. Correct. Vault Docs Insight: "Token auth... can be used by machines with proper management."
* E: AppRole - RoleID/SecretID for apps. Correct. Vault Docs Insight: "AppRole is designed for machine-to-machine authentication..."
* F: AWS - IAM roles for AWS resources. Correct. Vault Docs Insight: "AWS auth... automated for AWS-based machines."
* G: LDAP - User directory-based, human-oriented. Incorrect. Vault Docs Insight: "LDAP...
commonly for human user authentication."
* H: OIDC - User SSO, not M2M. Incorrect. Vault Docs Insight: "OIDC... for human single sign-on." Overall Explanation from Vault Docs:
"Examples of machine auth methods include AppRole, AWS, Kubernetes, TLS, and Token... Human auth methods include LDAP, GitHub, OIDC." Reference: https://developer.hashicorp.com/vault/docs/auth


問題 #70
What of the following features are true about batch tokens in Vault? (Select two)

答案：A,B

解題說明：
Comprehensive and Detailed In-Depth Explanation:
Batch tokens are lightweight tokens in Vault, designed for high-performance use cases.
* A: They are not persisted to storage, reducing backend load, as confirmed by the batch token tutorial.
* C: In Vault Enterprise with DR Replication, batch tokens are replicated and remain valid across clusters when the secondary is promoted, per replication docs.
* B: Batch tokens cannot be renewed; they have a fixed TTL, per the service vs. batch token comparison.
* D: They cannot create child tokens, lacking features of service tokens.

問題 #71
True or False? When encrypting data with the Transit secrets engine, Vault always stores the ciphertext in a dedicated KV store along with the associated encryption key.

答案：A

解題說明：
Comprehensive and Detailed in Depth Explanation:
* A:Incorrect. Transit doesn't store ciphertext; it returns it to the client.
* B:Correct. The Transit engine performs encryption/decryption without persisting data.
Overall Explanation from Vault Docs:
"The Vault Transit secrets engine does NOT store any data... Ciphertext is returned to the caller." Reference:https://developer.hashicorp.com/vault/docs/secrets/transit


問題 #72
Which of the following features in Vault will replicate service tokens between clusters?

答案：A

解題說明：
Comprehensive and Detailed In-Depth Explanation:
Vault Enterprise supports replication to synchronize data across clusters, with two main types:Disaster Recovery (DR) ReplicationandPerformance Replication. Only one replicates service tokens:
* A. Disaster Recovery Replication: This feature replicates critical data, including service tokens, between clusters for warm-standby failover. "DR clusters are essentially a warm-standby and do replicate tokens from the primary cluster," per the documentation. This ensures continuity in disaster scenarios.
* Incorrect Options:
* B. Performance Replication: Focuses on scaling read performance, not token replication.
"Performance clusters create and maintain their own tokens. These tokens are NOT replicated."
* C. Vault Agent: A client-side tool for token management, not cluster replication. "It does not specifically replicate service tokens between clusters."
* D. Integrated Storage: A storage backend, not a replication mechanism. "It does not directly replicate service tokens between clusters." DR Replication is designed for full data consistency, including tokens, across clusters.

問題 #73
Vault supports which type of configuration for source limited token?

答案：C

解題說明：
Vault supports CIDR-bound tokens, which are tokens that can only be used from a specific set of IP addresses or network ranges. This is a way to limit the scope and exposure of a token in case it is compromised or leaked. CIDR-bound tokens can be created by specifying the bound_cidr_list parameter when creating or updating a token role, or by using the -bound-cidr option when creating a token using the vault token create command. CIDR-bound tokens can also be created by some auth methods, such as AWS or Kubernetes, that can automatically bind the tokens to the source IP or network of the client.
