In the example below, where is the value of the DNS record's IP address originating from? 1. resource "aws_route53_record" "www" 2. { 3. zone_id = aws_route53_zone.primary.zone_id 5. type = "A" 6…

The correct answer is B. The output of a module named web_server. In a parent module, outputs of child modules are available in expressions as module.<MODULE NAME>.<OUTPUT NAME>. For example, if a child module named web_server declared an output named instance_ip_address, you could access that value as module.web_server.instance_ip_address.
