VCP-VMC 2024 Question 83
Single answerA company has deployed a critical application on VMware Cloud on AWS. The application requires a disaster recovery solution to minimize downtime and data loss in case of a regional failure. The company's RTO (Recovery Time Objective) is 1 hour, and the RPO (Recovery Point Objective) is 15 minutes. Which disaster recovery method is most appropriate in this scenario?
- A
Use VMware Cloud Disaster Recovery (VCDR) with scheduled snapshot replication every 24 hours.
- B
Implement VMware Site Recovery with continuous replication.
- C
Use a manual backup solution to copy data to an external storage service weekly.
- D
Leverage native VMware vSphere Replication with a replication interval of 15 minutes.
Show answer and explanation
Correct answer: B
Explanation
The correct solution for this scenario is VMware Site Recovery with continuous replication. It provides an enterprise-grade disaster recovery solution that meets both the RTO and RPO requirements of the application. Other options are either too slow or lack the necessary automation and reliability for critical workloads.
- A. Incorrect.
This option is incorrect because a 24-hour snapshot replication schedule does not meet the RPO of 15 minutes. The data loss could be significant in case of a failure.
- B. Correct.
This option is correct because VMware Site Recovery provides continuous replication, ensuring that the RPO is met. Additionally, it offers automated failover and recovery workflows, which help achieve the 1-hour RTO.
- C. Incorrect.
This option is incorrect because a manual backup solution with weekly backups is unsuitable for a critical application with an RPO of 15 minutes and an RTO of 1 hour.
- D. Incorrect.
This option is incorrect because while vSphere Replication can meet the RPO of 15 minutes, it is not as robust as VMware Site Recovery for disaster recovery, especially in terms of automated failover to meet the RTO.
