CompTIA Network+ (N10-008) — Question 470

A network administration team for a medium-sized business has decided to segment the network, logically separating the finance and marketing teams in order to improve performance for both teams. The finance and marketing teams still need to access resources across the subnets, and the router has a single interface. Which of the following should the administrator configure in order to allow the traffic?

Answer options

• A. Port address translation
• B. Classless masking
• C. IPv6 tunneling
• D. Subinterfaces

Correct answer: D

Explanation

The correct answer is D, Subinterfaces, as they allow a single physical interface on a router to handle multiple logical subnets, enabling communication between different VLANs. The other options do not provide the necessary functionality for routing traffic between subnets: A pertains to translating IP addresses, B relates to subnetting schemes, and C involves encapsulating IPv6 traffic, none of which solve the problem at hand.
