SAP-C02 Question 206
Single answerA retail company operates an e-commerce platform hosted entirely in AWS. The company wants to implement a disaster recovery strategy to ensure minimal downtime and data loss in the event of a regional failure. They require the ability to quickly failover to another AWS region while maintaining near-real-time data replication. Which disaster recovery strategy should they implement?
- A
Backup and restore
- B
Pilot light
- C
Warm standby
- D
Multi-site
Show answer and explanation
Correct answer: C
Explanation
Warm standby is the most suitable disaster recovery strategy for this scenario. It provides a balance between cost and recovery objectives, with near-real-time data replication and the ability to quickly scale up the secondary environment in the event of a regional failure. Other options either do not meet the quick failover requirement (backup and restore, pilot light) or are unnecessarily expensive for the company's needs (multi-site).
- A. Incorrect.
Backup and restore involves storing backups in another region and restoring them when needed. While cost-effective, this approach has a higher recovery time objective (RTO) and recovery point objective (RPO), which does not meet the company's requirements for quick failover and minimal data loss.
- B. Incorrect.
Pilot light maintains minimal infrastructure in the secondary region, such as a small-scale version of critical systems. However, scaling up from a pilot light configuration can take time, which does not meet the company's need for quick failover.
- C. Correct.
Warm standby involves running a scaled-down version of the production environment in the secondary region, with near-real-time data replication. This allows for quicker failover and minimal data loss, meeting the company's requirements.
- D. Incorrect.
Multi-site involves running full production environments in multiple regions simultaneously. While it provides the quickest failover capability, this approach is significantly more expensive and may exceed the company's requirements.
