How can the domain’s zone apex for example "myzoneapexdomain com" be pointed towards an Elastic Load Balancer?
A . By using an AAAA record
B . By using an A record
C . By using an Amazon Route 53 CNAME record
D . By using an Amazon Route 53 Alias record
Answer: D
Explanation:
Alias resource record sets are virtual records that work like CNAME records. But they differ from CNAME records in that they are not visible to resolvers. Resolvers only see the A record and the resulting IP address of the target record. As such, unlike CNAME records, alias resource record sets are available to configure a zone apex (also known as a root domain or naked domain) in a dynamic environment.
