The correct answer is A. MX.
Explanation:
MX stands for Mail Exchange record. It is a type of DNS record that specifies the mail server responsible for accepting email messages on behalf of a domain. When someone sends an email to a particular domain, their email client uses DNS to look up the MX record for that domain. Once the MX record is found, the email client can connect to the mail server specified in the MX record to deliver the email message.
Therefore, when configuring a new email server, a technician needs to modify the MX record to point to the new email server's address. This will ensure that email functions as expected and is delivered to the correct mail server.
Option B, C, and D are incorrect:
B. CNAME stands for Canonical Name record. It is a type of DNS record that allows multiple domain names to be associated with the same IP address. CNAME records are typically used for creating aliases or shortcuts for domain names. They are not used for email servers.
C. AAAA stands for IPv6 Address record. It is a type of DNS record that maps a domain name to an IPv6 address. AAAA records are used for IPv6 addresses, while A records are used for IPv4 addresses. They are not used for email servers.
D. SRV stands for Service record. It is a type of DNS record that specifies the location of a service or server. SRV records are used for locating specific services on a network, such as Active Directory or SIP servers. They are not used for email servers.
