QUESTION 9:

The Certkiller network is displayed in the diagram below:

Referring to the devices shown above, which statements are true in this scenario.
(Select two)
A. All the devices in both networks will receive a broadcast to 255.255.255.255 sent by
host Certkiller A.
B. Only the devices in network 192.168.1.0 will recive a broadcast to 255.255.255.255
sent by host Certkiller A.
C. All the devices on both networks are members of the same collision domain.
D. The hosts on the 192.168.1.0 network form one collision domain, and the hosts on the
192.168.2.0 network form a second collision domain.
E. Each host is in a separate collision domain.

Answer: B, E
Explanation:
Since the devices shown in the diagram are switches, B is in fact correct. D is not correct.
If the diagram used hubs and not switches then yes, there would only be two collision
domains, but the diagram has switches. The author may have intended to state broadcast
domains which would have been correct as well.
Answer E is also correct, since the network is comprised of switches each host will be in
a separate collision domain
