1. 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

2. Select the statements that are correct concerning network protocols. (Choose three.)
define the structure of layer specific PDU’s
dictate how to accomplish layer functions
outline the functions necessary for communications between layers
limit the need for hardware compatibility
require layer dependent encapsulations
eliminate standardization among vendors

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

4. 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

Network
Transport
Physical
Data Link
Session

6. 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
