質問 # 127
According to the screenshot below, what auth method did this client use to log in to Vault?
(Screenshot shows a lease path: auth/userpass/login/student01)
正解：D
解説：
Comprehensive and Detailed in Depth Explanation:
The screenshot provides a lease path: auth/userpass/login/student01, which reveals the authentication method used to generate the token tied to this lease. Vault's auth methods create tokens at specific paths, and the path structure indicates the method.
* Option A: UserpassThe path auth/userpass/login/student01 explicitly includes userpass, matching the userpass auth method. This method authenticates users with a username (e.g., student01) and password, typically via vault login -method=userpass username=student01. The /login endpoint confirms a login operation, and the lease ties to the resulting token. This is the clear, correct answer based on the path.
Correct.Vault Docs Insight:"The userpass auth method allows users to authenticate with a username and password... mounted at auth/userpass by default." (Matches the path.)
* Option B: Auth"Auth" isn't an auth method-it's the namespace prefix (auth/) for all auth methods in Vault (e.g., auth/token, auth/userpass). The screenshot specifies userpass within auth/, not a generic
"auth" method. This option is a misnomer and incorrect.Vault Docs Insight:"All auth methods are mounted under auth/... 'auth' itself is not a method." (Clarifies structure.)
* Option C: Root tokenA root token is a privileged token type, not an auth method. It's created during Vault initialization or via auth/token/create with root privileges, not through a login path like auth
/userpass/login. The screenshot's path indicates a userpass login, not a root token usage. Incorrect.
Vault Docs Insight:"Root tokens are created at initialization... not tied to a specific auth method login path." (Distinct from userpass.)
* Option D: Child tokenA child token is a token created by a parent token (e.g., via vault token create), not an auth method. The path auth/userpass/login/student01 shows a login event, not a token creation event (which would be auth/token/create). This option confuses token hierarchy with authentication.
Incorrect.Vault Docs Insight:"Child tokens are created by parent tokens... not directly via login endpoints." (Different mechanism.) Detailed Mechanics:
When a user logs in with vault login -method=userpass -path=userpass username=student01, Vault hits the endpoint POST /v1/auth/userpass/login/student01 with a password payload. Success generates a token, and a lease is created at auth/userpass/login/student01 with a TTL. The screenshot's lease path directly reflects this process, pinpointing userpass as the method.
Real-World Example:
Enable userpass: vault auth enable userpass. Add user: vault write auth/userpass/users/student01 password=secret. Login: vault login -method=userpass username=student01. The token's lease appears as auth
/userpass/login/student01.
Overall Explanation from Vault Docs:
"The lease shown lives at auth/userpass/login/<username> and indicates the userpass auth method was used to obtain a token... The userpass method authenticates via username/password at its mount path." The path structure is a definitive indicator.

質問 # 128
From the options below, select the auth methods that are better suited for machine-to-machine authentication (select five):
正解：A、B、C、F、H
解説：
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
質問 # 129
The following three policies exist in Vault. What do these policies allow an organization to do?
正解：A
解説：
The three policies that exist in Vault are:
* admins: This policy grants full access to all secrets and operations in Vault. It can be used by administrators or operators who need to manage all aspects of Vault.
* default: This policy grants access to all secrets and operations in Vault except for those that require specific policies. It can be used as a fallback policy when no other policy matches.
* transit: This policy grants access only to the transit secrets engine, which handles cryptographic functions on data in-transit. It can be used by applications or services that need to encrypt or decrypt data using Vault.
These policies allow an organization to perform useful tasks such as:
* Encrypting, decrypting, and rewrapping data using the transit engine all in one policy: This policy grants access to both the transit secrets engine and the default policy, which allows performing any operation on any secret in Vault.
* Creating a transit encryption key for encrypting, decrypting, and rewrapping encrypted data: This policy grants access only to the transit secrets engine and its associated keys, which are used for encrypting and decrypting data in transit using AES-GCM with a 256-bit AES key or other supported key types.
* Separating permissions allowed on actions associated with the transit secret engine: This policy grants access only to specific actions related to the transit secrets engine, such as creating keys or wrapping requests. It does not grant access to other operations or secrets in Vault.
質問 # 130
Based on the output below, how many policies have been added to Vault?
$ vault policy list
base
default
root
web-app-1
automation-team
正解：C
解説：
Comprehensive and Detailed In-Depth Explanation:
The vault policy list command displays all policies in Vault. The output lists five policies: "base","default",
"root", "web-app-1", and "automation-team". However, "root" and "default" are built-in policies:
* Built-in Policies:
* "root": A superuser policy created by default.
* "default": Provides common permissions, also default. "Vault has two default policies, root and default."
* Added Policies:
* "base", "web-app-1", "automation-team" are not built-in, meaning they were added. Thus,3 policieswere added.
* Incorrect Options:
* B. 4: Overcounts by including one built-in.
* C. 1, D. 2: Undercounts the added policies.

質問 # 131
How can Vault be used to programmatically obtain a generated code for MFA, somewhat similar to Google Authenticator?
正解：A
解説：
Comprehensive and Detailed in Depth Explanation:
Vault can generate time-based one-time passwords (TOTP) for multi-factor authentication (MFA), mimicking apps like Google Authenticator. Let's evaluate:
* Option A: CubbyholeCubbyhole is a per-token secret store, not a TOTP generator. It's for temporary secretstorage, not MFA code generation. Incorrect.Vault Docs Insight:"Cubbyhole stores secrets tied to a token... no TOTP functionality." (Different purpose.)
* Option B: The random byte generatorVault's /sys/tools/random endpoint generates random bytes, not time-based codes synced with a clock (TOTP requirement). It's for generic randomness, not MFA.
Incorrect.Vault Docs Insight:"Random bytes are not time-based... unsuitable for TOTP." (Unrelated feature.)
* Option C: TOTP secrets engineThe TOTP engine generates and validates TOTP codes (e.g., 6-digit codes every 30s) using a shared secret, just like Google Authenticator. You create a key (vault write totp
/keys/my-key) and fetch codes (vault read totp/code/my-key). Perfect for programmatic MFA. Correct.
Vault Docs Insight:"The TOTP secrets engine can act as a TOTP code generator... replacing traditional generators like Google Authenticator." (Exact match.)
* Option D: The identity secrets engineThe Identity engine manages user/entity identities and policies, not TOTP codes. It's for identity management, not MFA generation. Incorrect.Vault Docs Insight:
"Identity engine handles identity data... no TOTP generation." (Different scope.) Detailed Mechanics:
Enable: vault secrets enable totp. Create key: vault write totp/keys/my-key issuer=Vault. Get code: vault read totp/code/my-key returns {"data":{"code":"123456"}}. Codes sync with time (RFC 6238), usable in APIs or apps.
Overall Explanation from Vault Docs:
"The TOTP secrets engine can act as a TOTP code generator... It provides an added layer of security since the ability to generate codes is guarded by policies and audited." Reference:https://developer.hashicorp.com/vault/docs/secrets/totp
