2V0-21.23 Question 144
Single answerAn organization has a primary data center and a secondary data center used for disaster recovery (DR). The organization wants to ensure that critical workloads can failover to the secondary site with minimal downtime in the event of a disaster. Which disaster recovery use case is the most appropriate for this scenario?
- A
Active-Passive disaster recovery with manual failover
- B
Active-Active disaster recovery with automated failover
- C
Backup and restore from secondary storage at the secondary site
- D
Cold disaster recovery with on-demand provisioning of workloads
Show answer and explanation
Correct answer: B
Explanation
The organization requires minimal downtime for critical workloads during a disaster. Active-Active disaster recovery with automated failover ensures high availability and rapid failover by having both sites operational and capable of sharing the workload, making it the best fit for this use case. Other options, such as Active-Passive, backup and restore, or cold disaster recovery, involve longer recovery times and more manual intervention, which do not align with the organization's requirements.
- A. Incorrect.
Active-Passive disaster recovery with manual failover involves a secondary site that remains idle until a disaster occurs, requiring manual intervention to bring workloads online. This results in higher downtime and is less ideal for ensuring minimal downtime.
- B. Correct.
Active-Active disaster recovery with automated failover allows both sites to share the workload, with automated mechanisms to failover critical workloads during a disaster. This approach significantly reduces downtime, making it the most appropriate for the given scenario.
- C. Incorrect.
Backup and restore relies on restoring data from backups stored at the secondary site. This process is slower and does not meet the minimal downtime requirement for critical workloads.
- D. Incorrect.
Cold disaster recovery requires setting up and provisioning workloads only after a disaster occurs. This approach is time-intensive and unsuitable for ensuring minimal downtime.
