問題 #49
After creating a dynamic credential on a database, the DBA accidentally deletes the credentials on the database itself. When attempting to remove the lease, Vault returns an error stating that the credential cannot be found. What command can be run to make Vault remove the secret?
答案：B
解題說明：
Comprehensive and Detailed in Depth Explanation:
When a dynamic credential is deleted externally, Vault may fail to revoke the lease due to the missing backend secret. The HashiCorp Vault documentation states: "The -force flag is meant for recovery situations where the secret in the target platform was manually removed." The command vault lease revoke -force - prefix <lease_path> allows Vault to forcibly revoke all leases under the specified prefix, bypassing the error.
The docs elaborate: "Using -force with -prefix will revoke all leases that match the given prefix, even if the underlying secrets cannot be found or revoked on the target system. This is useful for cleaning up Vault's lease table when external changes disrupt normal revocation." Here, <lease_path> would be the path like database/creds/role/.B (vault lease -renew)renews leases, not removes them.C (-enforce)is not a valid flag.D (vault revoke -apply)is incorrect syntax. Thus, A is correct.

問題 #50
Which of the following secrets engines does NOT issue a lease upon a read request?
答案：D
解題說明：
Comprehensive and Detailed in Depth Explanation:
Leases tie to dynamic secrets with TTLs. Let's check:
* A: KV- Static secrets, no lease on read. Correct.
* B: Consul- Dynamic creds with leases. Incorrect.
* C: Database- Dynamic creds with leases. Incorrect.
* D: AWS- Dynamic creds with leases. Incorrect.
Overall Explanation from Vault Docs:
"The Key/Value Backend... does not issue leases although it may return a lease duration." Reference:https://developer.hashicorp.com/vault/docs/concepts/lease#lease-renew-and-revoke
問題 #51
When Vault is sealed, which are the only two operations available to a Vault administrator? (Select two)
答案：B,C
解題說明：
Comprehensive and Detailed in Depth Explanation:
When Vault is sealed, its functionality is severely restricted to protect encrypted data. The HashiCorp Vault documentation states: "While Vault is sealed, the only two options available are viewing the vault status (vault status) and unsealing Vault (vault operator unseal). All the other actions require Vault to be unsealed and the user to be authenticated." This limitation ensures that no operations can access or modify data until the Vault is unsealed, enhancing security.
The documentation under "Shamir Seals" further elaborates: "When Vault is sealed, it knows where its encrypted data is stored but cannot decrypt it because the master key is not in memory. The only available operations are checking the seal status and initiating the unseal process." Thus:
* A (View the status of Vault): The vault status command works when sealed, providing details like seal state.
* E (Unseal Vault): The vault operator unseal command allows administrators to begin unsealing.
Options likeconfigure policies (B),view data in the key/value store (C),rotate the encryption key (D), and author security policies (F)require an unsealed Vault and authentication, making A and E the correct selections.

問題 #52
What command can be used to update a Vault policy named web-app-1 using the command line?
答案：B
解題說明：
Comprehensive and Detailed In-Depth Explanation:
To update an existing Vault policy via the CLI, the correct command is vault policy write:
* D. vault policy write web-app-1 web.hcl: This command updates (or creates if it doesn't exist) the policy named "web-app-1" with the contents of "web.hcl". The documentation states: "The write keyword is used to update an existing policy with the contents of the specified file."
* Incorrect Options:
* A. vault policy create: No such subcommand exists; create is invalid. "The create keyword is not a valid subcommand."
* B. vault policy fmt: Formats the HCL file but doesn't update Vault. "It is used to format a policy file."
* C. vault policy update: Incorrect syntax; Vault uses write, not update. "There is no update command, only write." The write command's dual purpose (create or update) simplifies policy management.

問題 #53
Examine the command below. Output has been trimmed.
Which of the following statements describe the command and its output?
答案：A,D
解題說明：
The command shown in the image is:
vault token create -policy=approle -orphan -period=60h
This command creates a new token with the following characteristics:
* It has the policy "approle" attached to it, which grants or denies access to certain paths and operations in Vault according to the policy rules. The policy can be defined by using the vault policy write command or the sys/policy API endpoint 1 2 .
* It is an orphan token, which means it has no parent token and it will not be revoked when its parent token is revoked. Orphan tokens can be useful for creating long-lived tokens that are not affected by the token hierarchy 3 .
* It has a period of 60 hours, which means it has a renewable TTL of 60 hours. This means that the token can be renewed indefinitely as long as it does not go past the 60-hour mark from the last renewal time.
The token's TTL will be reset to 60 hours upon each renewal. Periodic tokens are useful for creating tokens that have a fixed lifetime and can be easily revoked 4 .
