Hi,
Can somebody guide me about the multiocast address in the following question:

Which of the following is the ether net multicast address?
A. 07:01:05:03:05:05
B. 07:01:02:03:04:05
c. 04:07:02:03:04:05
D. 07:01:04:06:04:05

I have got following from a site:

In practice, a one value in the least significant bit of the most significant byte represents a multicast. That's a fancy way of saying that the address must start with an odd "section" (01, 03, 05, 07, 09, 0b, 0d, 0f, 11, 13, 15, 17, 19, 1b, 1d, 1f all the way through ff).

Considering above A, B, & D seems to be the correct option.
Kindly guide me.

Similarly for the following question:

Which of the following is not a ethernet unicast destination address?
A. 44:AA:c1:23:45:32
B. 43:7b:6c:de:10:00
C. 46:56:21:1A: DE:F4
D. 48:32:21:21:4D:34

In my opinion B is the correct option because it starts with odd value??
Kindly guide me.

Zulfi.

 

From my limited understanding I believe you are correct.
