Suggested Answer: B Vote an answer

The information that the Inter-Switch Link Protocol configuration uses in the configuration created is B.
MAC tables.
The Inter-Switch Link Protocol (ISL) is a protocol that enables the synchronization of data and state information between two VSX peer switches. The ISL uses a version control mechanism and provides backward compatibility regarding VSX synchronization capabilities. The ISL can span long distances (transceiver dependent) and supports different speeds, such as 10G, 25G, 40G, or 100G1.
One of the data components that the ISL synchronizes is the MAC table, which is a database that stores the MAC addresses of the devices connected to the switch and the corresponding ports or VLANs. The ISL ensures that both VSX peers have the same MAC table entries and can forward traffic to the correct destination2. The ISL also synchronizes other data components, such as ARP table, LACP states for VSX LAGs, and MSTP states2.
