Question
A SysOps administrator launches two Amazon EC2 instances and creates a single public subnet for testing purposes in the same Availability Zone. The SysOps administrator wants Amazon Route 53 to respond with a public IP address only if a test webpage on an instance is running. However, even when the test webpage is unavailable, Route 53 still responds with the public IP addresses from both instances. How can the SysOps administrator resolve this issue?
Options
- ACreate a Route 53 multivalue answer routing record. Associate a health check with the record.
- BConfigure latency-based routing with a health check in Route 53.
- CConfigure weighted routing in Route 53.
- DCreate another public subnet in the same Availability Zone for one of the instances.

Explanation
A Route 53 multivalue answer record lets you return multiple IPs but automatically omits any whose associated health check fails. That exactly meets the need to serve an instance’s public IP only when its test webpage is healthy, without changing topology or using latency/weighting logic.
