Which next step should be taken to configure Route 53?

A SysOps administrator is evaluating Amazon Route 53 DNS options to address concerns about high availability for an on-premises website. The website consists of two servers: a primary active server and a secondary passive server. Route 53 should route traffic to the primary server if the associated health check returns 2xx or 3xx HTTP codes. All other traffic should be directed to the secondary passive server. The failover record type, set ID. and routing policy have been set appropriately for both primary and secondary servers.

Which next step should be taken to configure Route 53?
A . Create an A record for each server. Associate the records with the Route 53 HTTP health check.
B . Create an A record for each server. Associate the records with the Route 53 TCP health check.
C . Create an alias record for each server with evaluate target health set to yes. Associate the records with the Route 53 HTTP health check.
D . Create an alias record for each server with evaluate target health set to yes. Associate the records with the Route 53 TCP health check.

Answer: C

Explanation:

To configure Route 53 for high availability with failover between a primary and a secondary server, the following steps should be taken:

Create Health Checks:

Create HTTP health checks for both the primary and secondary servers. Ensure these health checks are configured to look for HTTP 2xx or 3xx status codes.

Reference: Creating and Updating Health Checks

Create Alias Records:

Create an alias record for the primary server. Set "Evaluate Target Health" to Yes. Associate this record with the primary server’s HTTP health check.

Create an alias record for the secondary server. Set "Evaluate Target Health" to Yes. Associate this record with the secondary server’s HTTP health check.

Reference: Creating Records by Using the Amazon Route 53 Console Set Routing Policy:

Ensure the routing policy for both records is set to "Failover."

Assign appropriate "Set IDs" and configure the primary record as the primary failover record and the secondary record as the secondary failover record.

Reference: Route 53 Routing Policies

Test Configuration:

Test the failover configuration to ensure that when the primary server health check fails, traffic is routed to the secondary server.
