CompTIA Network+ (N10-008) — Question 48

A technician is searching for a device that is connected to the network and has the device's physical network address. Which of the following should the technician review on the switch to locate the device's network port?

Answer options

• A. IP route table
• B. VLAN tag
• C. MAC table
• D. QoS tag

Correct answer: C

Explanation

The correct answer is C, the MAC table, because it maps MAC addresses to their corresponding ports on the switch, allowing the technician to find the device easily. The IP route table relates to routing information, the VLAN tag pertains to virtual LANs, and the QoS tag is associated with quality of service settings, none of which will directly help in locating the device by its physical address.
