(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 Observable 1 correctness of response Description Option 1, Option 3, and Option 5are correct. 1 point for each correct option. 0 points if more options are selected than required. Max Value 3

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 compatibilityrequire layer dependent encapsulations eliminate standardization among vendors Observable Description Option 1, Option 3, and Option 5 are correct. 1 point for each correct option. 0 points if more options are selected than required. Max Value 3

1 correctness of response

3

What are two functions of encapsulation? (Choose two.) tracks delay between end devices enables consistent network pathsfor 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 Observable Description Option 4 and Option 5 are correct. 1 point for each correct option. 0 points if more options are selected than required. Max Value 2

1 correctness ofresponse

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 Observable Description 2 points for Option 1 Max Valuehttp://ev-iip.netacad.net/virtuoso/delivery/pub-doc/exam_viewer.shtml?QUESTIONS_PE... 01/03/2011
