Answer 1

The resource record set that would not be allowed for the hosted zone example.com is www.example.ca.

The Domain Name System (DNS) uses resource record sets to map domain names to IP addresses. In the given question, the hosted zone is for the domain example.com. The resource record sets that would not be allowed for this hosted zone are:

1. A. www.example.com: This is a valid subdomain of example.com.
2. B. www.aws.example.com: This is a valid subdomain of example.com.
3. C. www.example.ca: This is a different top-level domain (TLD) and is not allowed in the hosted zone for example.com.
4. D. www.beta.example.com: This is a valid subdomain of example.com.

Therefore, the correct answer is C. www.example.ca.
