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.
Use RTO, RPO, and Recovery Objectives to define the target, Backup vs Replication to separate historical recovery from live copies, and Recovery Strategy Patterns to compare backup and restore, pilot light, warm standby, and active designs. This page adds the AWS and DOP-C02 interpretation.
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.
