• Chose C1

  I picked C, but Latnecy could also work. For each latency record pointing to an EC2 instance (non-alias record): Create a Route 53 health check that monitors the EC2 instance (HTTP, HTTPS, or TCP on a specific port/path). Associate that health check with the latency record. Route 53 continuously runs these health checks (every 10–30 seconds by default).

• Chose C5

  https://docs.aws.amazon.com/Route53/latest/DeveloperGuide/routing-policy.html#routing-policy-multivalue "Multivalue answer routing policy – Use when you want Route 53 to respond to DNS queries with up to eight healthy records selected at random. You can use multivalue answer routing to create records in a private hosted zone." Company requires that the IP addresses of "ALL" healthy EC2 instances be returned so C is the only option.

  Use a multivalue answer routing policy to help distribute DNS responses across multiple resources. For example, use multivalue answer routing when you want to associate your routing records with a Route 53 health check. For example, use multivalue answer routing when you need to return multiple values for a DNS query and route traffic to multiple IP addresses.
