In computer networking ,a multicast address is an identifier for a group of hosts that have joined a multicast group. Multicast addressing can be used in the Link Layer (OSI Layer 2), such as Ethernet Multicast, as well as at the Internet Layer (OSI Layer 3) as IPv4 or IPv6 Multicast. Which two descriptions are correct regarding multicast addressing?
A. The last 3 bytes (24 bits) of the multicast MAC address are 0x01-00-5E. This is a reserved value that indicates a multicast application.
B. To calculate the Layer 2 multicast address, the host maps the last 23 bits of the IP address into the last 24 bits of the MAC address. The high-order bit is set to 0.
C. The first 23 bits of the multicast MAC address are 0x01-00-5E. This is a reserved value that indicates a multicast application.
D. The first 3 bytes (24 bits) of the multicast MAC address are 0x01-00-5E. This is a reserved value that indicates a multicast application.

QUESTION 137
Study the exhibit carefully. Configure BGP on all routers, turn off synchronization , and none of the default attributes have been changed except the local preference attribute on P4S4. Which path will be preferred by P4S2 to reach the network 100.100.100.0/24?
A. P4S2, P4S1 because it has the shortest AS-path
B. P4S2, P4S3, P4S4, P4S5 because it has a higher local preference
C. P4S2, P4S1 because it has a lower local preference
D. P4S2, P4S3, P4S4, P4S5 because it has a lower admin distance
