The correct answer for the question "Which multicast destination MAC address is assigned to LACP?" is A. 01:80:c2:00:00:03.
LACP (Link Aggregation Control Protocol) is a protocol used to bundle multiple physical links into a single logical link to increase bandwidth and provide redundancy. LACP operates in a peer-to-peer fashion and uses a multicast destination MAC address to communicate with other LACP-enabled devices.
The multicast destination MAC address assigned to LACP is 01:80:c2:00:00:03. This MAC address falls under the IEEE-defined range of multicast MAC addresses that are reserved for link-layer control protocols.
To understand this better, let's break down the MAC address into its components:
The first three octets (01:80:c2) represent the IEEE-assigned organizational unique identifier (OUI) for multicast addresses.
The fourth octet (00) is reserved for the Ethernet version number, which is set to 0 for all Ethernet frames.
The fifth octet (00) is reserved for the LACP protocol identifier, which is set to 0x01 for LACP.
The sixth octet (03) is the LACP-specific destination address extension, which is set to 0x03 for LACP.
Therefore, the correct answer is A. 01:80:c2:00:00:03.
