When setting up domain name settings for a client's company, you are directed to assign a DNS resource record to facilitate inbound emails to their onsite electronic message handling server. Which type of DNS resource record will you need to configure?
AAAA record for linking the domain solely to an IPv6 address.
A record to direct internet traffic to the specific host where the server is located.
MX record to define the destination mail server and its priority for the domain.
CNAME record to alias the company's domain to the email server's domain.
A Mail Exchanger (MX) record directs the flow of email by specifying the mail server responsible for accepting email messages for the domain and is essential for any domain that intends to receive emails. In contrast, an 'A' record links a domain to an IP address for general purpose use, and 'AAAA' records are similar but for IPv6 addresses. A 'CNAME' record creates an alias for a domain, which is not applicable for directing email traffic.
