Take a look at this:

Answer: A, C, D, F
Notice they say that Multicasting can contribute to LAN congestion but looky here:
You are experiencing intermittent issues relating to congestion with your network. What are the possible causes of congestion on a LAN? (Choose all that apply.) A. A broadcast domain with too many hosts. B. Full duplex operation. C. Broadcast storms. D. Multicasting. E. Network Segmentation. F. Low bandwidth.
Answer: A, C, F
No mention of Multicasting. Hummmm. They explain:
"D. Multicasting can actually alleviate congestion issues, as single streams of information can reach multiple hosts at the same time, instead of using a series of point to point connections."
Are the questions the same? Different? Opinions?
