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
D & F according to the provided link http://www.ciscopress.com/articles/article.asp?p=2738463&seqNum=2
D and F
Well According to the link correct is A and D
http://www.ciscopress.com/articles/article.asp?p=2738463&seqNum=2
Probably D and F. From the provided link,
“The high-order 25 bits is the official reserved multicast MAC address range from 0100.5E00.0000 to 0100.5E7F.FFFF (request for Comment 1112). These bits are part of the organizational unit identifiers (OUI).”
“The lower-order 23 bits of the destination IP multicast address are mapped to the lower-order 23 bits of the MAC address.”
