"When a switch employs the store-and-forward switching mechanism, it decides whether or not to participate in fast forwarding based on the source MAC address of a frame received." Will you look at this claim?

The first packet is process-switched and the following packets in the flow are forwarded using the cache and without CPU intervention. This forwarding method is called: A) Process Switching. B) Fast Switching. C) Cisco Express Forwarding (CEF).

Now suppose there is only one link between source and destination, and there are 10 FDM channels in the link. The MP3 file is sent over one of the channels. What is the end-to-end delay?

Refer to the diagram above. The initial state of SW1 and SW2 forwarding tables is shown next to Alpha and Foxtrot, respectively. Assume that all switch ports have all default settings. Answer questions below. Treat each objective as independent from others, i.e. start each objective with the same initial state of the two forwarding tables (shown). When Bravo sends a unicast frame to Charlie, will SW1 forward or flood this frame, and out which port(s)? Will SW2 forward or flood this frame, and, if yes, out which port(s)? When Charlie replies to Bravo, will SW1 forward or flood this frame, and out which port(s)?
