AWS Certified SysOps Administrator SOA-C01 – Question054

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

Correct Answer: D

Explanation:

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.
