Question

For an ecommerce platform, an architect is reviewing disaster recovery requirement set 21. Which design choice best fits the requirement while following AWS architectural best practices?

2. B. Match backup and restore, pilot light, warm standby, or active-active patterns to rto and rpo.
3. C. Use long-lived access keys in application configuration so services can call AWS APIs directly.
4. D. Disable monitoring until the workload reaches steady production traffic.

Correct Answer

B. Match backup and restore, pilot light, warm standby, or active-active patterns to rto and rpo.

Explanation

The best answer applies disaster recovery: match backup and restore, pilot light, warm standby, or active-active patterns to RTO and RPO. The other options increase operational risk, weaken security, or remove observability that an AWS Solutions Architect should preserve.
