CompTIA Network+ (N10-009) — Question 1
While troubleshooting a VoIP handset connection, a technician's laptop is able to successfully connect to network resources using the same port. The technician needs to identify the port on the switch. Which of the following should the technician use to determine the switch and port?
Answer options
- A. LLDP
- B. IKE
- C. VLAN
- D. netstat
Correct answer: A
Explanation
LLDP (Link Layer Discovery Protocol) is used to discover devices and their connections on a network, making it the right choice for identifying the switch and port. IKE (Internet Key Exchange) is related to security protocols and not useful for port identification. VLAN (Virtual Local Area Network) pertains to network segmentation rather than physical port identification. Netstat is a command-line tool for network connections, but it does not provide information about switch ports.
