VCP-VMC 2024 Question 147
Single answerA company is planning to deploy a disaster recovery (DR) solution using VMware Cloud Disaster Recovery. The company has a critical application that requires an RPO (Recovery Point Objective) of 15 minutes and a low-cost storage solution for secondary data copies. Which configuration should the administrator prioritize to meet these requirements?
- A
Configure continuous replication with VMware Cloud Disaster Recovery using an on-demand failover site.
- B
Set up scheduled snapshots with a 15-minute interval and store them in cost-efficient cloud storage.
- C
Deploy VMware Site Recovery with synchronous replication for zero RPO.
- D
Leverage vSphere Replication with a 15-minute RPO and use VMware Cloud on AWS as the DR site.
Show answer and explanation
Correct answer: D
Explanation
For a 15-minute RPO and a low-cost storage requirement, vSphere Replication with a 15-minute RPO and VMware Cloud on AWS as the DR site is the most appropriate choice. It balances cost-efficiency with the ability to meet the RPO requirements. Other options either do not meet the RPO criteria, are unsuitable for critical applications, or are unnecessarily expensive for the given scenario.
- A. Incorrect.
Continuous replication is not supported by VMware Cloud Disaster Recovery, and an on-demand failover site might not meet the 15-minute RPO requirement due to replication limitations and failback complexities.
- B. Incorrect.
While scheduled snapshots every 15 minutes could meet the RPO, they are not typically suitable for real-time critical application recovery since snapshots introduce delays and are not ideal for frequent incremental replication.
- C. Incorrect.
Synchronous replication ensures zero RPO, but it is a costlier solution that does not align with the company's need for a low-cost storage solution. This approach is over-engineered for the 15-minute RPO requirement.
- D. Correct.
vSphere Replication supports a 15-minute RPO and can replicate data to VMware Cloud on AWS, which provides a cost-effective and scalable solution for disaster recovery.
