NEW QUESTION # 326
Before the following command can be run to encrypt data, what (three) commands must be run to enable and configure the transit secrets engine in Vault? (Select three) text CollapseWrapCopy
$ vault write transit/encrypt/vendor \
plaintext="aGFzaGljb3JwIGNlcnRpZmllZA=="
Answer: A,C,E
Explanation:
Comprehensive and Detailed in Depth Explanation:
To encrypt data using the Transit secrets engine, it must be enabled and configured. The HashiCorp Vault documentation states: "Enable the Transit secrets engine at the default path of 'transit' using the command vault secrets enable transit. Create an encryption key called 'vendor' using the command vault write -f transit
/keys/vendor. Encode the string using base-64 encoding by using the command base64 <<< 'hashicorp certified'." These steps are prerequisites for the given vault write transit/encrypt/vendor command:
* A (base64 <<< "hashicorp certified"): The docs note, "All plaintext data must be base64-encoded.
The reason for this requirement is that Vault does not require that the plaintext is 'text'. It could be a binary file such as a PDF or image. The easiest safe transport mechanism for this data as part of a JSON payload is to base64-encode it." The provided plaintext aGFzaGljb3JwIGNlcnRpZmllZA== is the base64 encoding of "hashicorp certified."
* D (vault secrets enable transit): "Before you can use the transit secrets engine, it must be enabled with vault secrets enable transit at the default path 'transit/'."
* E (vault write -f transit/keys/vendor): "An encryption key must be created before encryption can occur. Use vault write -f transit/keys/vendor to generate a key named 'vendor'." Bis the target command, not a prerequisite.C (vault secrets list)lists engines but doesn't configure Transit.
Thus, A, D, and E are correct.

NEW QUESTION # 327
When using the Vault Secrets Operator, where is the secret written to after being retrieved from Vault?
Answer: C
Explanation:
Comprehensive and Detailed in Depth Explanation:
* A:Incorrect; VSO writes to Kubernetes Secrets.
* B:Incorrect; not written to pod filesystem.
* C:VSO syncs secrets to Kubernetes Secrets. Correct.
* D:Incorrect; no automatic cloud provider integration.
Overall Explanation from Vault Docs:
"VSO synchronizes secrets from Vault to Kubernetes Secrets..."

NEW QUESTION # 328
To make an authenticated request via the Vault HTTP API, which header would you use?
Answer: B
Explanation:
To make an authenticated request via the Vault HTTP API, you need to use the X-Vault-Token HTTP Header or the Authorization HTTP Header using the Bearer <token> scheme. The token is a string that represents your identity and permissions in Vault. You can obtain a token by using an authentication method, such as userpass, approle, aws, etc. The token can also be a root token, which has unlimited access to Vault, or a wrapped token, which is a response-wrapping token that can be used to unwrap the actual token. The token must be sent with every request to Vault that requires authentication, except for the unauthenticated endpoints, such as sys/init, sys/seal-status, sys/unseal, etc. The token is used by Vault to verify your identity and enforce the policies that grant or deny access to various paths and operations.

NEW QUESTION # 329
What command would you use to enable the Kubernetes secrets engine at the path of /k8s-cluster?
Answer: D
Explanation:
Comprehensive and Detailed In-Depth Explanation:
Correct syntax is:
* A. vault secrets enable -path=k8s-cluster kubernetes: "The secrets enable command enables a secrets engine at a given path." The -path flag precedes the engine type.
* Incorrect Options:
* B: kv put is for key-value data, not enabling engines.
* C: Incorrect CLI syntax; API-focused.
* D: Reversed order; path must come first.

NEW QUESTION # 330
You have enabled the Transit secrets engine and want to start encrypting data to store in Azure Blob storage.
What is the next step that needs to be completed before you can encrypt data? (Select two)
Answer: B,C
Explanation:
Comprehensive and Detailed In-Depth Explanation:
The Transit secrets engine in Vault is designed for encryption as a service, allowing applications to encrypt data without managing keys locally. After enabling the engine, two critical steps are required before encryption can begin: creating an encryption key and defining a policy to allow its use.
Option C: You must create an encryption key using a command like vault write -f transit/keys/ < key_name >
. This key is stored in Vault and used for encryption/decryption operations. Without it, no encryption can occur, as the Transit engine relies on named keys to perform cryptographic operations.
Option D: A policy must be written to grant the application permissions to use the key, such as path " transit
/encrypt/ < key_name > " { capabilities = [ " update " ] } and path " transit/decrypt/ < key_name > " { capabilities = [ " update " ] }. Vault's access control ensures that only authorized entities can perform encryption, making this step essential.
Option A (exporting the key) contradicts Vault's security model, as keys should remain in Vault, not be exported to application servers. Option B (enabling the Transit API) is unnecessary, as enabling the engine automatically exposes its API endpoints. The official Transit documentation confirms that key creation and policy configuration are the next steps post-enablement.
