Thanks for posting your question.
An Alias record in the context of Route53 maps a domain name to an AWS Resource endpoint. A non-alias record can resolve a domain name to another domain or to a stable IP address.
In the scenario, the alternate endpoint was assumed to be a custom endpoint. Note that both records can be used as failover targets.
Let me know if this answers your question.
