CompTIA Network+ (N10-008) — Question 43

A technician is configuring a network switch to be used in a publicly accessible location. Which of the following should the technician configure on the switch to prevent unintended connections?

Answer options

• A. DHCP snooping
• B. Geofencing
• C. Port security
• D. Secure SNMP

Correct answer: C

Explanation

Port security is the correct choice because it restricts the devices that can connect to the switch ports, thereby preventing unauthorized access. DHCP snooping helps protect against rogue DHCP servers, but it doesn't directly prevent connections. Geofencing is not applicable to network switches, and Secure SNMP is focused on securing management access rather than controlling port access.
