NEW QUESTION # 65
Your organization has applications in a primary data center and a secondary warm-standby site. You want to configure Vault replication between the primary and secondary clusters. If the primary fails over to the secondary, the applications must interact with Vault without re-authenticating. What type of Vault replication would you use?
Answer: D
Explanation:
Comprehensive and Detailed In-Depth Explanation:
Vault Enterprise supports two replication types: Performance Replication and Disaster Recovery (DR) Replication. The key requirement here is that applications must continue interacting with Vault without re- authenticating during a failover from the primary to the secondary cluster. DR Replication is designed for this exact scenario. It replicates all data, including tokens and leases, from the primary cluster to the secondary cluster. When the secondary is promoted to primary during a failover, the existing tokens remain valid, allowing applications to seamlessly continue operations without re-authentication.
Performance Replication, while improving scalability and performance by replicating data across clusters, manages its own tokens and leases on each secondary cluster. Tokens from the primary are not replicated, so a failover would invalidate existing tokens, requiring applications to re-authenticate-failing the requirement.
Integrated Storage is a storage backend, not a replication type, and doesn't address failover behavior. The Vault Secrets Operator is a Kubernetes tool for secret management, unrelated to cluster replication. According to Vault's DR Replication documentation, it ensures continuity of token validity, making it the correct choice.

NEW QUESTION # 66
You want to generate a token with a TTL of 24 hours which can be renewed indefinitely.
Which flag would you use on the following command?
vault token create
Answer: C
Explanation:
The correct flag is -period=24h because it creates a periodic token. A periodic token receives a fixed renewal period, and every renewal uses that period. As long as the token is actively renewed and no explicit maximum TTL is imposed, it can continue to be renewed indefinitely. The -ttl=24h flag only sets the initial TTL; normal token renewal is still constrained by maximum TTL values from the token, mount, auth method, parent token, or system configuration. The -explicit-max-ttl=0 option alone does not create a periodic token. The -orphan flag removes the parent relationship but does not make the token indefinitely renewable. HashiCorp's token create command documentation shows -period as the periodic-token flag.
NEW QUESTION # 67
Your application cannot manage authentication with Vault, but it can communicate with a local service to retrieve secrets. What solution can enable your app to generate dynamic credentials from Vault?
Answer: B
Explanation:
Comprehensive and Detailed in Depth Explanation:
For an application that cannot manage authentication with Vault but can communicate with a local service, the Vault Proxy with Auto-Auth feature enabledis the optimal solution. The HashiCorp Vault documentation states that Vault Proxy can "act as a proxy between Vault and the application, optionally simplifying the authentication process." The Auto-Auth feature allows the proxy to handle authentication on behalf of the application, enabling it to generate dynamic credentials without the application needing to manage the authentication process directly. This aligns perfectly with the requirement of delegating authentication to a local service.
Vault Proxy with cachingimproves performance by caching responses but does not inherently handle authentication, missing the core need.Vault Agent with environment variable secret injectioninjects secrets into the application's environment but assumes the agent manages authentication, which the application cannot do.Vault Agent with templatinggenerates credentials based on templates but still requires authentication management, which the application cannot handle. Vault Proxy with Auto-Auth uniquely addresses this by offloading authentication responsibilities.

NEW QUESTION # 68
Although batch and service tokens share many characteristics, which of the following are true only about batch tokens? (Select three)
Answer: A,B,C
Explanation:
Comprehensive and Detailed In-Depth Explanation:
Batch and service tokens differ in key ways, with these unique tobatch tokens:
* C. Maintain a single fixed TTL: "Batch tokens maintain a single fixed TTL," non-renewable, unlike service tokens.
* D. Valid across clusters: "They are valid for either the primary or any secondary clusters," enhancing flexibility in replicated setups.
* E. Not persisted to disk: "Batch tokens are not persisted to disk," reducing exposure risk.
* Incorrect Options:
* A. Can create child tokens: "Batch tokens cannot create child tokens," unlike service tokens.
* B. Renewable: "Batch tokens are not renewable," a key distinction from service tokens.
Batch tokens prioritize lightweight, ephemeral use.
