CompTIA Network+ (N10-007) — Question 437

Which of the following properties should be configured to extend logical network separation on an uplink interface to a second switch?

Answer options

• A. 802.1Q trunking
• B. Multiple untagged ports
• C. Port mirroring
• D. Management VLAN

Correct answer: A

Explanation

The correct answer is A, 802.1Q trunking, as it allows multiple VLANs to be carried over a single physical link, enabling logical network separation. The other options do not provide the same capability; multiple untagged ports do not facilitate VLAN separation, port mirroring is used for traffic analysis, and management VLAN is focused on administrative access rather than extending separation.
