1. Which statements correctly identify the role of intermediary devices in the network? (Choose three.)
xdetermine pathways for data
initiate data communications
xretime and retransmit data signals
originate the flow of data
xmanage data flows
final termination point for data flow

2. Select the statements that are correct concerning network protocols. (Choose three.)
xdefine the structure of layer specific PDU’s
dictate how to accomplish layer functions
xoutline the functions necessary for communications between layers
limit the need for hardware compatibility
xrequire 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
xidentifies pieces of data as part of the same communication
xensures 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?
xsupports error detection
ensures ordered arrival of data
provides delivery to correct destination
identifies the devices on the local network

Mijn opmerking was een sarcastische opmerking. Maar ik heb al een leuk nummer gevonden om het hier weer wat levendiger te maken. Speciaal nummer voor Bart.
