QUESTION NO: 83
One of the best ways to understand how to build a network is to understand the method in which traffic
is passed across the network. One of the reasons the OSI model was created to help you understand how
a network operates. Which three devices operate at all seven layers of the OSI model? (Choose three.)
A. Network host
B. Network management station
C. Transceiver
D. Bridge
E. Web server
F. Switch
DDR(Dial on demand routing)
QUESTION NO: 155
The network 131.107.0.0 needs to be divided into subnets where each subnet has the capacity of 458 IP
addresses. What would be the correct subnet mask to accomplish this division keeping the number of
subnets at the maximum?

C. All TCP protocols will be permitted out of Ethernet 0 except e-mail and telnet.
D. All IP traffic out of Ethernet 0 will be denied.
E. The access-list is numbered incorrectly and will fail.
QUESTION NO: 223
Which of the following correctly describe IP addressing? (Choose Two)
A. IP multicast addresses start with 240.
B. A host portion of all 1’s indicates a network broadcast.
