CompTIA Network+ (N10-009) — Question 26

A network administrator needs to create an SVI on a Layer 3-capable device to separate voice and data traffic. Which of the following best explains this use case?

Answer options

• A. A physical interface used for trunking logical ports
• B. A physical interface used for management access
• C. A logical interface used for the routing of VLANs
• D. A logical interface used when the number of physical ports is insufficient

Correct answer: C

Explanation

The correct answer is C because an SVI (Switched Virtual Interface) allows for the routing of VLANs, enabling the separation of voice and data traffic. Options A and B pertain to physical interfaces and management access, which do not address the need for logical separation of traffic. Option D is incorrect because the creation of an SVI does not relate to the number of physical ports.
