CompTIA Network+ (N10-008) — Question 522

A technician received a report that some users in a large, 30-floor building are having intermittent connectivity issues. Users on each floor have stable connectivity, but do not have connectivity to other floors. Which of the following devices is MOST likely causing the issue?

Answer options

• A. User devices
• B. Edge devices
• C. Access switch
• D. Core switch

Correct answer: D

Explanation

The core switch is responsible for routing traffic between different segments of a network, which includes communication between floors. If users on each floor can connect to their local devices but not to other floors, it is likely that the core switch is malfunctioning or misconfigured. The other options, such as user devices and access switches, would not typically affect inter-floor connectivity.
