CompTIA Network+ (N10-007) — Question 233

A network technician installs a web server on the firewall. Which of the following methods should the technician implement to allow access to outside users without giving access to the inside network?

Answer options

• A. VLAN
• B. DMZ
• C. SNMP
• D. NTP

Correct answer: B

Explanation

The correct answer is B, as a DMZ (Demilitarized Zone) allows external users to access the web server while keeping the internal network secure. VLANs (A) are used for segmentation within the same network but do not provide the same level of security for external access. SNMP (C) and NTP (D) are protocols used for network management and time synchronization, respectively, and do not facilitate external access in this context.
