CompTIA Network+ (N10-008) — Question 303
An organization set up its offices so that a desktop is connected to the network through a VoIP phone. The VoIP vendor requested that voice traffic be segmented separately from non-voice traffic. Which of the following would allow the organization to configure multiple devices with network isolation on a single switch port?
Answer options
- A. Subinterfaces
- B. Link aggregation
- C. Load balancing
- D. Tunneling
Correct answer: A
Explanation
The correct answer is A, Subinterfaces, because they allow for the creation of virtual interfaces on a single physical interface, enabling the segmentation of traffic types. Options B, C, and D do not provide network isolation on a switch port; Link aggregation combines multiple links for redundancy and increased bandwidth, Load balancing distributes traffic across multiple paths, and Tunneling encapsulates packets for secure communication but does not achieve the desired traffic segmentation.
