Which three fields are used in a UDP segment header? (Choose three.)

• Window Size
• Length
• Source Port
• Acknowledgment Number
• Checksum

Which factor determines TCP window size?

• the amount of data to be transmitted
• the number of services included in the TCP segment
• the amount of data the destination can process at one time
• the amount of data the source is capable of sending at one time

What are three responsibilities of the transport layer? (Choose three.)

• meeting the reliability requirements of applications, if any
• multiplexing multiple communication streams from many users or applications on the same network
• identifying the applications and services on the client and server that should handle transmitted data
• directing packets towards the destination network
• formatting data into a compatible form for receipt by the destination devices

What does a client do when it has UDP datagrams to send?

• It just sends the datagrams.
• It queries the server to see if it is ready to receive data.
• It sends a simplified three-way handshake to the server.
• It sends to the server a segment with the SYN flag set to synchronize the conversation.

When 2 or more bits in a data unit has been changed during the transmission, the error is called:

• random error
• burst error
• inverted error
• double error

What is the function of the CRC value that is found in the FCS field of a frame?

• to verify the integrity of the received frame
• to verify the physical address in the frame
• to verify the logical address in the frame
• to compute the checksum header for the data field in the frame

What is contained in the trailer of a data-link frame?

• logical address
• physical address
• data
• error detection

Refer to the exhibit. ServerB is attempting to contact HostA. Which two statements correctly identify the addressing that ServerB will generate in the process? (Choose two.)

• ServerB will generate a packet with the destination IP address of RouterB.
• ServerB will generate a frame with the destination MAC address of SwitchB.
• ServerB will generate a packet with the destination IP address of RouterA.
• ServerB will generate a frame with the destination MAC address of RouterB.
• ServerB will generate a packet with the destination IP address of HostA.

Which statement accurately describes a TCP/IP encapsulation process when a PC is sending data to the network?

• Data is sent from the internet layer to the network access layer.
• Packets are sent from the network access layer to the transport layer.
• Segments are sent from the transport layer to the internet layer.
• Frames are sent from the network access layer to the internet layer.

What method can be used by two computers to ensure that packets are not dropped because too much data is being sent too quickly?

• encapsulation
• flow control
• access method
• response timeout
