CNA

A PC is downloading a large file from a server. The TCP window is 1000 bytes. The server is sending the file using 100-byte segments. How many segments will the server send before it requires an acknowledgment from the PC?

• 1 segment

• 10 segments

• 100 segments

• 1000 segments

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 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.

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

• Window Size

• Length

• Source Port

• Checksum

What are two roles of the transport layer in data communication on a network? (Choose two.)

• identifying the proper application for each communication stream

• tracking the individual communication between applications on the source and destination hosts

• providing frame delimiting to identify bits making up a frame

• performing a cyclic redundancy check on the frame for errors

What information is used by TCP to reassemble and reorder received segments?

• port numbers

• sequence numbers

• acknowledgment numbers

• fragment numbers

What important information is added to the TCP/IP transport layer header to ensure communication and connectivity with a remote network device?

• timing and synchronization

• destination and source port numbers

• destination and source physical addresses

• destination and source logical network addresses

Which two characteristics are associated with UDP sessions? (Choose two.)

• Destination devices receive traffic with minimal delay.

• Transmitted data segments are tracked

• Destination devices reassemble messages and pass them to an application.

• Received data is unacknowledged.

• Unacknowledged data packets are retransmitted.

A client application needs to terminate a TCP communication session with a server. Place the termination process steps in the order that they will occur. (Not all options are used.)

Which flag in the TCP header is used in response to a received FIN in order to terminate connectivity between two network devices?

• FIN

• ACK

• SYN

• RST
