Final answer:
To point a domain to an Azure load balancer, create an A Record for IPv4 or an AAAA Record for IPv6, depending on the type of IP address the load balancer uses.
Step-by-step explanation:
To point a domain name to an Azure load balancer, you would typically create an A Record if you are using IPv4 addresses or an AAAA Record if you are using IPv6 addresses. An A Record maps a domain name to its corresponding IPv4 address, while an AAAA Record does the same for an IPv6 address. Since Azure's load balancers can have either type of IP address, you would choose the record type accordingly.
It's not usual to point directly to a load balancer with a CNAME record because it is intended to map one domain name to another domain name, not to an IP address. As for the option 'Record Set,' it is a term used in DNS management for a collection of records that share the same name but may have different types (such as A, AAAA, CNAME, TXT, etc.), so it is not specific to point to an Azure load balancer.
