Which two design concerns must be addressed when designing a multicast implementation? (Choose two.)

A.
only the low-order 23 bits of the MAC address are used to map IP addresses

B.
only the low-order 24 bits of the MAC address are used to map IP addresses

C.
only the high-order 23 bits of the MAC address are used to map IP addresses

D.
only the low-order 23 bits of the IP address are used to map MAC addresses

E.
the 0x01004f MAC address prefix is used for mapping IP addresses to MAC addresses

F.
the 0x01005e MAC address prefix is used for mapping IP addresses to MAC addresses

Explanation:
– The low order bit (0x01) in the first octet indicates that this packet is a Layer 2 multicast packet. Furthermore, the “0x01005e” prefix has been reserved for use in
mapping L3 IP multicast addresses into L2 MAC addresses.
– When mapping L3 to L2 addresses, the low order 23 bits of the L3 IP multicast address are mapped into the low order 23 bits of the IEEE MAC address. Notice
that this results in 5 bits of information being lost.
