A company uses Route 53 with failover routing to direct traffic to a primary web server in us-east-1a and a secondary server in us-west-2a. The primary server's health check fails, but Route 53 continues to return the primary server's IP address. What is the most likely cause?

The TTL on the primary record is set to 300 seconds.

The health check is a TCP check.

The secondary record is set to routing policy 'weighted'.

The failover record for the primary is not associated with the health check.

A company uses Route 53 DNS failover to route traffic to a primary and secondary endpoint. What must be configured to ensure that traffic is redirected to the secondary endpoint when the primary fails?

A weighted routing policy with health checks associated with each record

A latency routing policy with health checks associated with each record

A failover routing policy with health checks associated with each record

A simple routing policy with health checks associated with each record

A target behind an Application Load Balancer is marked unhealthy. The health check requests are timing out. Which of the following is the most likely cause?

The health check path returns a 500 Internal Server Error

The target is returning a 301 redirect to a different path

The health check interval is set too high
