Once again, I am fighting with the answer keys in one of my BSCI books. Here are the questions I struggly with; I won't offer my answers nor the answer-key answers; I want to hear everyone's interpretations first.
1. Multicasting is efficient in terms of processor resources for which of the following reasons?
A. Multicasts can be ignored by the network card.
B. Multicasts have a specific set of IP addresses.
C. Multicasts are not routable.
D. Multicasts do not support TCP.
2. Which one of the following multicast addresses does not share a multicast MAC address?
3. Which of the following is not a capability of of UDP multicast?
A. Packet ordering
C. Limiting receivers
D. Dynamic membership
4. Multicasting supports applications that communicate
Number 2 is still a mystery to me - all the addresses listed are valid multicast IP addresses
Binary for all your address is
Since only last 23 digits are mapped to multicast address. You can see that address A, B,C will have the same multicast address though the IP address is differnt.so as per question they share the address.
Only D is different mulicast address. As Giuseppe noted D is the answer.
