Route53 must automatically route traffic to a standby region when the primary endpoint fails a health check. Which record configuration enables this?
A.Failover routing policy — PRIMARY record with health check + SECONDARY record
Active-passive + health check = failover policy. Correct.
B.Weighted routing with equal weights
Weighted splits traffic — doesn't do health-triggered switchover.
C.Multivalue answer routing
Multivalue returns several healthy IPs — not primary/standby semantics.
D.Latency-based routing
Latency optimizes speed — not failover design.
Why this answer
Failover routing = active-passive: PRIMARY record evaluated by health check; on failure DNS resolves to SECONDARY. This is Route53's DR mechanism — different from latency/weighted which distribute traffic normally.
