CCNA 1 Module 2 V4.0
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
