CompTIA A+ Core 1 (220-1101) — Question 472

Which of the following components houses the MX record?

Answer options

• A. DNS
• B. VLAN
• C. DHCP
• D. SMTP

Correct answer: A

Explanation

The MX record is stored in the DNS system, which is responsible for mapping domain names to IP addresses and managing email routing. VLAN, DHCP, and SMTP serve different purposes; VLAN is for network segmentation, DHCP for dynamic IP address assignment, and SMTP for sending emails, but none of these manage MX records.
