LACP stands for which protocol?

• A. Link Access Control Protocol
• B. Link Aggregation Control Protocol
• C. Local Area Connection Protocol
• D. Layered Application Control Protocol

Answer: (B)

LACP is the mechanism that negotiates and maintains a group of parallel links as a single logical link, enabling higher bandwidth and redundancy. It works by exchanging LACP Data Units between devices to share each side’s identity and port information, so both ends can agree which ports belong to the same link aggregation group and how they should operate. This dynamic negotiation allows a port channel to form automatically and adapt to topology changes, instead of relying on static, manual configuration. The standard term for this protocol is Link Aggregation Control Protocol. The other options don’t describe a protocol used to manage aggregated links.
