RecognitionAmazon Application Recovery Controller
Recovery readiness/failover context; no direct numbered skill names it.
Key points
- Application Recovery Controller supports recovery-readiness and failover context without receiving standalone skill depth.
Best-known use cases
- D2.1, D2.2, and D5.1: operate a named readiness or failover control inside an existing recovery design.
What candidates often confuse it with
- Application Recovery Controller concerns recovery coordination; Route 53 health, load-balancer target health, and workload capacity remain separate evidence layers.
Key takeaway
Keep ARC coverage tied to the stated recovery operation rather than inventing a broader architecture exercise.
