CCNA 1 Introduction to Networks Ver 6.0 – ITN Chapter 9

A host device needs to send a large video file across the network while providing data communication to other users. Which feature will allow different communication streams to occur at the same time, without having a single data stream using all available bandwidth?

• window size

• multiplexing

• port numbers

• acknowledgments

What is the complete range of TCP and UDP well-known ports?

• 0 to 255

• 0 to 1023

• 256 – 1023

• 1024 – 49151

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 three application layer protocols use TCP? (Choose three.)

• FTP

• TFTP

• SMTP

• HTTP

• SNMP

What kind of port must be requested from IANA in order to be used with a specific application?

• registered port

• private port

• dynamic port

• source port

What type of information is included in the transport header?

• destination and source physical addresses

• destination and source logical addresses

• destination and source port numbers

• encoded application data

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

• Destination devices receive traffic with minimal delay.

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

• Received data is unacknowledged.

• Unacknowledged data packets are retransmitted.

• Transmitted data segments are tracked.

What happens if part of an FTP message is not delivered to the destination?

• The FTP source host sends a query to the destination host.

• The message is lost because FTP does not use a reliable delivery method.

• The part of the FTP message that was lost is re-sent.

• The entire FTP message is re-sent.

What is a socket?

• the combination of the source and destination sequence and acknowledgment numbers

• the combination of a source IP address and port number or a destination IP address and port number

• the combination of the source and destination IP address and source and destination Ethernet address

• the combination of the source and destination sequence numbers and port numbers

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
