CompTIA A+ Core 1 (220-1101) — Question 71

Which of the following technologies can allow multiple networks to traverse a switch?

Answer options

• A. VLAN
• B. VRRP
• C. VPN
• D. DHCP

Correct answer: A

Explanation

The correct answer is A, VLAN, as it allows the segmentation of a physical switch into multiple logical networks, enabling distinct broadcast domains. VRRP, VPN, and DHCP serve different purposes: VRRP is for redundancy, VPN for secure remote connections, and DHCP for dynamic IP address allocation, none of which facilitate multiple network traffic through a switch.
