CCENT practice certification exam #2

1. Data is being sent from a source PC to a destination server. Which three statements correctly describe the function of TCP or UDP in this situation? (Choose three.)


The UDP destination port number identifies the application or service on the server which will handle the data.

TCP is the preferred protocol when a function requires lower network overhead.

UDP segments are encapsulated within IP packets for transport across the network.

The source port field identifies the running application or service that will handle data returning to the PC.

The TCP source port number identifies the sending host on the network.

The TCP process running on the PC randomly selects the destination port when establishing a session with the server.



2. In what two situations would UDP be the preferred transport protocol over TCP? (Choose two.)

when applications need to guarantee that a packet arrives intact, in sequence, and unduplicated

when a faster delivery mechanism is needed

when delivery overhead is not an issue

when applications do not need to guarantee delivery of the data

when destination port numbers are dynamic
