Which Layer 2 protocol helps troubleshoot network connectivity issues from Prism Element?

1. LLDP

2. HDLC

3. LACP

4. SUP

The correct answer is: LLDP

The Layer 2 protocol that helps troubleshoot network connectivity issues from Prism Element is LLDP, which stands for Link Layer Discovery Protocol. LLDP is a vendor-neutral protocol used in networking that enables devices in a local area network (LAN) to advertise their identity and capabilities to other devices on the same network segment. By utilizing LLDP, administrators can identify connected devices, view their properties, and discover network topology. This is particularly useful for troubleshooting connectivity issues because it provides visibility into how devices are interconnected, which can help pinpoint where issues are occurring in the network. With LLDP, you can easily gather critical information about neighboring devices, including their IP addresses, MAC addresses, and port details, enabling a more efficient troubleshooting process. Other protocols, while serving their specific purposes, do not specifically focus on network connectivity visibility in the same way LLDP does. HDLC, for instance, is used for point-to-point data link layer communication and doesn't assist in discovery and troubleshooting of connected devices. LACP, which stands for Link Aggregation Control Protocol, is used to manage link aggregation but does not provide device discovery functionalities. SUP, which stands for Switch Uplink Protocol, is less commonly referenced than the others and does not directly relate to troubleshooting connectivity in
