Study DOP-C02 recovery strategies, backup, restore automation, and RTO/RPO tradeoffs for resilient systems.
The recovery task on DOP-C02 is about matching the disaster-recovery pattern to the actual recovery objective. AWS is explicitly testing whether you can tell backup-and-restore from pilot light, warm standby, and more active patterns, and whether the selected design can meet the named RTO and RPO.
Do not start with a service name. Start with:
If the answer ignores one of those, it is usually not aligned to the business requirement.
| Requirement | Strongest first fit | Why |
|---|---|---|
| Longer recovery window is acceptable, lower cost matters | Backup and restore | Cheapest but slower recovery |
| Need faster recovery with partial warm infrastructure | Pilot light or warm standby | Better RTO than cold recovery |
| Need near-continuous regional continuity | More active multi-Region design | Stronger continuity, higher cost and complexity |
Backups matter, but DOP-C02 is usually asking whether restore, failover, or environment recreation can happen in time. If a choice says “take snapshots” but says nothing about recovery workflow or cross-Region availability when needed, it is often incomplete.
The strongest recovery answers usually include automated or rehearsed steps:
If the entire plan depends on humans rebuilding the service from memory under pressure, it is usually weak for DOP-C02.
When the question is about disaster recovery, translate the business requirement into RTO and RPO first. Then choose the least-complex pattern that still meets those objectives.
