Comprehensive and Detailed In-Depth Explanation:
The Link Layer Discovery Protocol (LLDP) is used for discovering neighboring devices. The given LLDP output contains key details about the neighboring device (R2), including its system name, interface, and management IP address. Let's analyze each option carefully:
* Option A: "The sysname of the peer device is R2." # Correct
* The output clearly shows System name: R2, which confirms that the neighbor's system name is indeed R2.
* Option B: "The interface number of the peer device is GE0/0/0." # Correct
* The Port ID in the LLDP output is GE0/0/0, which matches the statement in Option B.
* Option C: "The VLAN ID of the peer device is 1." # Incorrect
* The given LLDP output does not mention any VLAN ID information. Therefore, this option is false.
* Option D: "The management IP address of the peer device is 192.168.1.1." # Correct
* The Management address field in the LLDP output confirms the IP address as 192.168.1.1, making this statement true.
