CompTIA Network+ (N10-007) — Question 488

A server administrator is building an email server. To protect the corporate/internal network from external users, the email server should be placed:

Answer options

• A. on the intranet.
• B. in a subnet isolated from the internal network.
• C. on the company LAN segment.
• D. in the DMZ.

Correct answer: D

Explanation

The correct answer is D, as placing the email server in the DMZ allows it to be accessible from the internet while keeping the internal network secure. Options A and C would expose the internal network directly to external threats, while option B, while somewhat secure, does not provide the necessary external access for an email server.
