Question

A university provides access to AWS services for its students to submit their research data for analysis. The university is looking at a cost-effective approach for mitigating data loss or data corruption.

Which disaster recovery strategy is well-suited for this use case?

1. Warm standby strategy
2. Multi-site active/active strategy
3. Backup and restore strategy
4. Pilot light strategy

Answer 1

The Backup and Restore strategy is the most cost-effective disaster recovery strategy for a university using AWS services to analyze research data, focusing on data recovery rather than maintaining additional infrastructure.

Step-by-step explanation:

The question pertains to choosing the most cost-effective disaster recovery strategy for a university's use case involving AWS services for data analysis. Given the need to mitigate data loss or corruption, the most suitable strategy would be the Backup and Restore strategy. This approach involves regularly backing up data stored on AWS and restoring it in the event of a disaster. It is generally the most cost-effective option as it focuses on data recovery rather than maintaining a duplicate set of computing resources. Comparatively, warm standby, multi-site active/active, and pilot light strategies involve more infrastructure and hence incur higher costs, making them less cost-effective for the stated use case.
