Question 1
Explanation
Only a router or a Layer 3 switch can mitigate a broadcast storm because they separate broadcast domains -> B and D are correct.
Question 2
Explanation
AREA 1 has “multiple collision domains” so Network Device A must be a device operating in Layer 2 or above (a router or switch) -> A & E are correct.
AREA 2 only has “single collision domain” so Network Device B must be a device operating in Layer 1 (a hub or repeater) -> D is correct.
Question 3
Explanation
The “Ctrl-Shift-6″ and “x” is used to suspend the telnet session. In this case, the telnet session from Router1 to Router2 will be suspended.
If we enter the keyword “resume”, Router1 will try to resume the telnet session to Router2 (you will see the line [Resuming connection 1 to 192.168.9.2 … ]) and we will get back the Router2> prompt.
Question 4
Explanation
In the topology above only routers and switches are used so for each link we have one collision domains. In the picture below each pink ellipse represents for one collision domain.
