Citizens must reach a DR Region when the primary Region fails health checks. Which DNS design best supports that continuity?
Select an answer to reveal the explanation.
Short Explanation
DNS is the city’s traffic cop. Route 53 health checks watch the primary; when it fails, failover routing points citizens at the DR Region without a week-long wait for a manual edit.
Full Explanation
Route 53 health checks combined with failover routing policies redirect clients to a healthy secondary endpoint when the primary fails—core to multi-Region continuity. Device hosts files, hard-coded single-Region IPs, and delayed manual DNS edits do not provide timely automated failover.
