NEW QUESTION 172
How can Vault be used to programmatically obtain a generated code for MFA, somewhat similar to Google Authenticator?

Cubbyhole

The random byte generator

TOTP secrets engine

The identity secrets engine

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

NEW QUESTION 177
The key/value v2 secrets engine is enabled at secret/ See the following policy:

Which of the following operations are permitted by this policy? Choose two correct answers.

vault kv get secret/webapp1

vault kv put secret/webapp1 apikey-“ABCDEFGHI] K123M”

vault kv metadata get secret/webapp1

vault kv delete secret/super-secret

vault kv list secret/super-secret

The policy shown in the image is:
path “secret/data/webapp1” { capabilities = [“create”, “read”, “update”, “delete”, “list”] } path “secret/data/super-secret” { capabilities = [“deny”] } This policy grants or denies access to the key/value v2 secrets engine mounted at secret/ according to the following rules:
* The path “secret/data/webapp1” has the capabilities of “create”, “read”, “update”, “delete”, and “list”.
This means that the policy allows performing any of these operations on the secrets stored under this path. The data/ prefix is used to access the actual secret data in the key/value v2 secrets engine5. Therefore, the policy permits the operation of vault kv get secret/webapp1, which reads the secret data at secret/data/webapp16.
* The path “secret/data/super-secret” has the capability of “deny”. This means that the policy denies performing any operation on the secrets stored under this path. The policy overrides any other policy that might grant access to this path. Therefore, the policy does not permit the operations of vault kv delete secret/super-secret and vault kv list secret/super-secret, which delete and list the secret data at secret/data/super-secret respectively6.
* The policy does not explicitly define any rules for the path “secret/metadata”. The metadata/ prefix is used to access the metadata of the secrets in the key/value v2 secrets engine, such as the number of versions, the deletion status, the creation time, etc5. By default, if the policy grants any of the capabilities of “create”, “read”, “update”, or “delete” on the data/ path, it also grants the same capabilities on the corresponding metadata/ path7. Therefore, the policy permits the operation of vault kv metadata get secret/webapp1, which reads the metadata of the secret at secret/metadata/webapp18.

NEW QUESTION 181
Select the policies below that permit you to create a new entry of environment=prod at the path /secrets/apps
/my_secret (select three).

path “secrets/+/my_secret” { capabilities = [“create”] allowed_parameters = { “*” = [] } }

path “secrets/apps/my_secret” { capabilities = [“update”] }

path “secrets/apps/my_secret” { capabilities = [“create”] allowed_parameters = { “environment” = [] } }

path “secrets/apps/*” { capabilities = [“create”] allowed_parameters = { “environment” = [“dev”, “test”,
“qa”, “prod”] } }

Comprehensive and Detailed in Depth Explanation:
This question requires identifying Vault policies that allow creating a new entry with environment=prod at the specific path /secrets/apps/my_secret. Vault policies define permissions using paths, capabilities, and parameter constraints. Let’s evaluate each option:
* Option A: path “secrets/+/my_secret” { capabilities = [“create”] allowed_parameters = { “*” = []
} }The + wildcard matches any single segment in the path, so this policy applies to /secrets/apps
/my_secret. The create capability permits creating new entries at this path. The allowed_parameters = {
“*” = [] } means any parameter (including environment) can be set to any value. This satisfies the requirement to create an entry with environment=prod. Thus, this policy is correct.
* Option B: path “secrets/apps/my_secret” { capabilities = [“update”] }This policy targets the exact path /secrets/apps/my_secret but only grants the update capability. According to Vault’s documentation, update allows modifying existing entries, not creating new ones. Since the question specifies creating a new entry, this policy does not meet the requirement and is incorrect.
* Option C: path “secrets/apps/my_secret” { capabilities = [“create”] allowed_parameters = {
“environment” = [] } }This policy explicitly matches /secrets/apps/my_secret and grants the create capability, which allows new entries to be written. The allowed_parameters = { “environment” = [] } specifies that the environment parameter can take any value (an empty list means no restriction on values). This permits setting environment=prod, making this policy correct.
* Option D: path “secrets/apps/*” { capabilities = [“create”] allowed_parameters = {
“environment” = [“dev”, “test”, “qa”, “prod”] } }The * wildcard matches any path under secrets
/apps/, including /secrets/apps/my_secret. The create capability allows new entries, and the allowed_parameters restricts environment to dev, test, qa, or prod. Since prod is an allowed value, this policy permits creating an entry with environment=prod and is correct.
Overall Explanation from Vault Docs:
Vault policies control access via paths and capabilities (create, read, update, delete, list). The create capability is required to write new data. Parameter constraints (allowed_parameters) further restrict what key-value pairs can be written. An empty list ([]) allows any value, while a populated list restricts values to those specified. A deny takes precedence over any allow, but no deny is present here.

NEW QUESTION 182
If Bobby is currently assigned the following policy, what additional policy can be added to ensure Bobby cannot access the data stored at secret/apps/confidential but still read all other secrets?
path “secret/apps/*” { capabilities = [“create”, “read”, “update”, “delete”, “list”] }

path “secret/apps/confidential” { capabilities = [“deny”] }

path “secret/*” { capabilities = [“read”, “deny”] }

path “secret/apps/*” { capabilities = [“deny”] }

path “secret/apps/confidential/*” { capabilities = [“deny”] }

NEW QUESTION 183
A new Vault administrator is writing a CURL command (shown below) to retrieve a secret stored in a KV v2 secrets engine at secret/audio/soundbooth but is receiving an error. What could be the cause of the error?
$ curl
–header “X-Vault-Token: hvs.rffHw0iXqkRo19b2cjf93DM39WjpbN3J”
https://vault.unlimited.com:8200/v1/secret/audio/soundbooth

The VAULT_ADDR environment variable wasn’t set, so it should be configured: export VAULT_ADDR=”https://vault.unlimited.com:8200″

The request is being made on the incorrect endpoint and should be:
$ curl
–header “X-Vault-Token: hvs.rffHw0iXqkRo19b2cjf93DM39WjpbN3J”
https://vault.unlimited.com:8200/v1/secret/data/audio/soundbooth

The user’s token doesn’t permit access to the Vault API, only the UI

The endpoint should point to v2 since this is a KV v2 secrets engine:
$ curl
–header “X-Vault-Token: hvs.rffHw0iXqkRo19b2cjf93DM39WjpbN3J”
https://vault.unlimited.com:8200/v2/secret/audio/soundbooth
