NEW QUESTION # 328
Frapps, Inc. is a coffee startup specializing in frozen caffeinated beverages. Their new customer loyalty web app uses Vault to store sensitive information, choosing Integrated Storage for its benefits. Select the benefits the organization would see by using Integrated Storage over other storage backends (Select four)
Answer: B,C,D,F
Explanation:
Comprehensive and Detailed In-Depth Explanation:
Integrated Storage (Raft) offers several benefits over external storage backends. The Vault documentation states:
"Introduced in Vault 1.4, Integrated Storage is a built-in solution that provides a highly available, durable storage backend without relying on any external systems. All Vault data is stored locally on each node, and replicated to all other nodes in the cluster for high availability. It also reduces complexity since all configuration is done within Vault."
-Vault Configuration: Raft Storage
* C: Correct.
"Eliminates the requirement to deploy and manage a separate platform for storing encrypted data."
-Vault Configuration: Raft Storage
* D: Correct.
"Troubleshooting is simplified when using Integrated Storage because it is a built-in solution within Vault."
-Vault Configuration: Raft Storage
* E: Correct.
"Reduces operational overhead by keeping all configuration and data storage within Vault itself."
-Vault Configuration: Raft Storage
* F: Correct.
"Integrated Storage provides immediate access to stored data since it is stored locally on disk within Vault."
-Vault Configuration: Raft Storage
* A: Incorrect; Raft requires port 8201 for replication:
"The Vault cluster nodes still need to communicate over port 8201 for replication and RPC forwarding."
-Vault Configuration: Raft Storage
* B: Incorrect; Raft uses the RAFT protocol, not SERF:
"Integrated Storage uses the same underlying consensus protocol (RAFT) as Consul to handle cluster leadership and log management."
-Vault Configuration: Raft Storage

NEW QUESTION # 329
You logged into the Vault CLI and attempted to enable an auth method, but you received this error message.
What can you do to resolve the error and configure Vault?
(Error: dial tcp 127.0.0.1:8200: connect: connection refused)
Answer: C
Explanation:
Comprehensive and Detailed in Depth Explanation:
* A:Connection refused isn't a service issue here. Incorrect.
* B:Permissions don't cause connection errors. Incorrect.
* C:Invalid syntax change. Incorrect.
* D:Default
VAULT_ADDR is HTTPS; if TLS is off, set to http://127.0.0.1:8200. Correct.
Overall Explanation from Vault Docs:
"If
TLS is disabled, set VAULT_ADDR to http://127.0.0.1:8200 to avoid connection errors..." Reference:https://developer.hashicorp.com/vault/docs/commands#vault_addr
NEW QUESTION # 330
The vault lease renew command increments the lease time from:
Answer: A
Explanation:
The vault lease renew command increments the lease time from the current time, not the end of the lease. This means that the user can request a specific amount of time they want remaining on the lease, termed the increment. This is not an increment at the end of the current TTL; it is an increment from the current time. For example, vault lease renew -increment=3600 my-lease-id would request that the TTL of the lease be adjusted to 1 hour (3600 seconds) from now. Having the increment be rooted at the current time instead of the end of the lease makes it easy for users to reduce the length of leases if they don't actually need credentials for the full possible lease period, allowing those credentials to expire sooner and resources to be cleaned up earlier.
The requested increment is completely advisory. The backend in charge of the secret can choose to completely ignore it1. References:

NEW QUESTION # 331
Which of the following statements are true about Vault policies? Choose two correct answers.
Answer: B,C
Explanation:
Vault policies are written in HCL or JSON format and are attached to tokens or roles by name. Policies define the permissions and restrictions for accessing and performing operations on certain paths and secrets in Vault. Policies are deny by default, which means that an empty policy grants no permission in the system, and any request that is not explicitly allowed by a policy is implicitly denied 1 . Some of the features and benefits of Vault policies are:
* Policies are path-based, which means that they match the request path to a set of rules that specify the allowed or denied capabilities, such as create, read, update, delete, list, sudo, etc 2 .
* Policies are additive, which means that if a token or a role has multiple policies attached, the effective policy is the union of all the individual policies. The most permissive capability is granted if there is a conflict 3 .
* Policies can use glob patterns, such as * and +, to match multiple paths or segments with a single rule. For example, path "secret/*" matches any path starting with secret/, and path "secret/+/config" matches any path with two segments after secret/ and ending with config 4 .
* Policies can use templating to interpolate certain values into the rules, such as identity information, time, randomness, etc. For example, path "secret/{{identity.entity.id}}/*" matches any path starting with secret/ followed by the entity ID of the requester 5 .
* Policies can be managed by using the vault policy commands or the sys/policy API endpoints. You can write, read, list, and delete policies by using these interfaces 6 .
The default policy is a built-in policy that is attached to all tokens by default and cannot be deleted. However, the default policy can be modified by using the vault policy write command or the sys/policy API endpoint. The default policy provides common permissions for tokens, such as renewing themselves, looking up their own information, creating and managing response-wrapping tokens, etc 7 .
You do not have to use YAML to define policies, as Vault supports both HCL and JSON formats. HCL is a human-friendly configuration language that is also JSON compatible, which means that JSON can be used as a valid input for policies as well 8 .
Vault does not need to be restarted in order for a policy change to take effect, as policies are stored and evaluated in memory. Any change to a policy is immediately reflected in the system, and any token or role that has that policy attached will be affected by the change.
