CompTIA Network+ (N10-009) — Question 130

A company is moving to a hybrid cloud model. As part of this move the mail server will be moved to the cloud. The systems administrator needs to ensure the mail server continues to receive email. Which of the following types of DNS records should the systems administrator update?

Answer options

• A. NS
• B. PTR
• C. MX
• D. A

Correct answer: C

Explanation

The correct answer is C, MX records, as they are specifically used to direct email traffic to the correct mail server. Updating NS (A), PTR (B), or A (D) records would not ensure that emails are directed to the new mail server in the cloud.
