Thanks for the reply, I highly appreciate it.

I have one more clarification in another question.

A client is hosting their company website on a cluster of web servers that are behind a public-facing load balancer. The client also uses Amazon Route 53 to manage their public DNS.

How should the client configure the DNS zone apex record to point to the load balancer?

Answers

Create an A record aliased to the load balancer DNS name.

Create an A record pointing to the IP address of the load balancer.

Create a CNAME record pointing to the load balancer DNS name.

Create an alias for CNAME record to the load balancer DNS name.

#1 is correct answer, but I haven’t seen or able find a record type A record aliased. A record is used to typically DNS name to IP address and alias name is used mainly in mapping dns name to aws resources such as ALB. But I haven’t seen combination of A record and alias in AWS docs also, can you please explain? Am I missing anything?
