CompTIA A+ Core 1 (220-1101) — Question 218

Which of the following allows a switch to be divided into separate logical networks?

Answer options

• A. VLAN
• B. SSL VPN
• C. NAT
• D. RADIUS

Correct answer: A

Explanation

A VLAN (Virtual Local Area Network) allows network administrators to create separate logical networks within a single physical switch, which enhances network management and security. SSL VPN, NAT, and RADIUS serve different purposes: SSL VPN provides secure remote access, NAT translates IP addresses, and RADIUS is used for authentication and accounting, but none of them divide a switch into logical networks.
