CompTIA Network+ (N10-008) — Question 427

A company wants to mitigate unauthorized physical connectivity after implementing a hybrid work schedule. Which of the following will the company MOST likely configure?

Answer options

• A. Intrusion prevention system
• B. DHCP snooping
• C. ARP inspection
• D. Port security

Correct answer: D

Explanation

Port security is the most effective option for preventing unauthorized devices from connecting to the network by limiting the number of MAC addresses on a port. While intrusion prevention systems and DHCP snooping also enhance security, they do not specifically address unauthorized physical connections. ARP inspection helps to protect against ARP spoofing but is not directly related to physical port access control.
