Question

Question 08

A layer 3 device such as a router essentially breaks down a larger Broadcast Domain into two or more smaller broadcast domains. True False

Question 09

A layer 2 switch is connected to four computers A, B, C, and D. The switch's switching table is fully populated (i.e. no entries are missing). If A sends a frame destined for C, the switch will:

forward the frame to D but filter it to A and C

forward the frame to C but filter the frame to A, B, and D

forward the frame to C, B, and D but not A as it is the source

forward the frame to A, B, C, and D and only C will respond as the frame is destined to it.

Question 10.5 Switches send UNICAST Frames to all ports (except incoming) only when destination address is not present in their switching table. True False

Question 11 When multiple switches are present in a single network, a layer 2 switch knows only where to send an incoming frame next. It does not know the entire path the frame may eventually take. True False

Answer 1

Question 08 True, router helps to break broadcast domains by restricting the flow of broadcast message within a subnet.

Question 09  forward the frame to C but filter the frame to A, B, and D

Question 10.5 True. If the destination address is known then switch selectively forwards the frame to appropriate destination.

Question 11 True, layer 2 switch maintains forwarding table corresponding to the mac-address to decide the next node to forward frame based on the mac address.
