How does "DNS-based failover" with Amazon Route 53 work in a multi-region active-passive architecture?
Correct! Well done.
Incorrect.
The correct answer is A) Route 53 health checks continuously monitor the primary endpoint; if it becomes unhealthy, Route 53 automatically updates DNS responses to direct traffic to the secondary (passive) endpoint, based on configured failover routing policies
Correct Answer
Route 53 health checks continuously monitor the primary endpoint; if it becomes unhealthy, Route 53 automatically updates DNS responses to direct traffic to the secondary (passive) endpoint, based on configured failover routing policies
Route 53 failover routing uses health checks to determine endpoint status and automatically shifts DNS answers from a primary to a secondary resource when the primary fails health checks, enabling automated multi-region disaster recovery (subject to DNS TTL propagation delays).
