CompTIA Network+ (N10-009) — Question 338

A network technician is attempting to map networking devices. When logged in to the local switch, the technician uses LLDP and discovers only those devices that are connected directly to the switch. Which of the following should the technician perform to discover all the networking devices?

Answer options

• A. Reconfigure the management IP addresses of the networking devices on the same subnet.
• B. Enable Spanning Tree Protocol to allow the switches on the network to be discovered.
• C. Log in to each of the connected networking devices and perform the process again.
• D. Upgrade the OS on the networking devices to the current version of LLDP.

Correct answer: C

Explanation

The correct answer is C because logging into each connected networking device allows the technician to perform LLDP discovery directly on those devices, which may not be visible from the switch alone. Options A and B do not address the issue of direct discovery, and option D, while potentially useful for ensuring compatibility, does not solve the immediate problem of discovering devices.
