1. Which two layers of the OSI model have the same functions as the TCP/IP model 
Network Access Layer? (Choose two.) 
Network 
Transport 
Physical** 
Data Link** 
Session 


2. What is a primary function of the trailer information added by the data link layer 
encapsulation? 
supports error detection** 
ensures ordered arrival of data 
provides delivery to correct destination 
identifies the devices on the local network 
assists intermediary devices with processing and path selection 

3. During the encapsulation process, what occurs at the data link layer? 
No address is added. 
The logical address is added. 
The physical address is added.** 
The process port number is added. 

4. What device is considered an intermediary device? 
file server 
IP phone 
laptop 
printer 
switch** 

5. Which layer encapsulates the segment into packets? 
physical 
data link 
network**
transport 

6. Which statements correctly identify the role of intermediary devices in the 
network? (Choose three.) 
determine pathways for data** 
initiate data communications 
retime and retransmit data signals** 
originate the flow of data 
manage data flows** 
final termination point for data flow 

7. What can be identified by examining the network layer header? 
the destination device on the local media the path to use to reach the destination host** 
the bits that will be transferred over the media 
the source application or process creating the data 

8. What is the proper order of the layers of the OSI model from the highest layer to 
the lowest layer? 
physical, network, application, data link, presentation, session, transport 
application, physical, session, transport, network, data link, presentation 
application, presentation, physical, session, data link, transport, network 
application, presentation, session, transport, network, data link, physical** 
presentation, data link, session, transport, network, physical, application 

9. 







 Refer to the exhibit. Which three labels correctly identify the network types for the 
network segments that are shown? (Choose three.) 
Network A -- WAN 
Network B -- WAN** 
Network C -- LAN** 
Network B -- MAN 
Network C -- WAN 
Network A -- LAN** 

10. What are the key functions of encapsulation? (Choose three.) 
allows modification of the original data before transmission 
identifies pieces of data as part of the same communication** 
enables consistent network paths for communication 
ensures that data pieces can be directed to the correct receiving end device** 
enables the reassembly of complete messages** 
tracks delay between end devices 

11. 
  




 Refer to the exhibit. Which networking term describes the data interleaving process 
represented in the graphic? 
piping 
PDU 
streaming 
multiplexing** 
encapsulation 

12. What is a PDU? 
corruption of a frame during transmission 
data reassembled at the destination 
retransmitted packets due to lost communication 
a layer specific encapsulation** 

13. 


 Refer to the exhibit. "Cell A" at IP address 10.0.0.34 has established an IP session 
with "IP Phone 1" at IP address 172.16.1.103. Based upon the graphic, which device 
type best describes the function of wireless device "Cell A?" 
the destination device 
an end device** 
an intermediate device 
a media device 

14. 


Refer to the exhibit. Which set of devices contains only end devices? 
A, C, D 
B, E, G, H 
C, D, G, H, I, J 
D, E, F, H, I, J 
E, F, H, I, J** 

15.  





Refer to the exhibit. Which term correctly identifies the device type that is included in 
the green area? 
source 
end 
transfer 
**intermediary 

16. Which three statements best describe a Local Area Network (LAN)? (Choose 
three.) 
A LAN is usually in a single geographical area.** 
The network is administered by a single organization.** 
The connection between segments in the LAN is usually through a leased connection. 
The security and access control of the network are controlled by a service provider. 
A LAN provides network services and access to applications for users within a 
common** organization. 
Each end of the network is generally connected to a Telecommunication Service 
Provider (TSP). 

17. 
  






 Refer to the exhibit. What type of network is shown? 
WAN 
MAN 
**LAN 
WLAN 

18. What is the purpose of the TCP/IP Network Access layer? 
path determination and packet switching 
data representation, encoding, and control 
reliability, flow control, and error detection 
**detailing the components that make up the physical link and how to access it 
the division of segments into packets 

19. Which characteristic correctly refers to end devices in a network? 
manage data flows 
**originate data flow 
retime and retransmit data signals 
determine pathways for data 

20. What is the primary purpose of Layer 4 port assignment? 
to identify devices on the local media to identify the hops between source and destination 
o identify to the intermediary devices the best path through the network 
to identify the source and destination end devices that are communicating 
**to identify the processes or services that are communicating within the end devices 

21. Select the statements that are correct concerning network protocols. (Choose 
three.)
