CCNA V7 - Chapter 14 - Transport Layer - Module Quiz

Each request is assigned source and destination port numbers

How does a networked server manage requests from multiple clients for different services?

The source decreases the amount of data that it transmits before it receives an acknowledgement form the destination

Network congestion has resulted in the source learning of the loss of TCP segments that were sent to the destination. What is one way that the TCP protocol addresses this?

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

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

tracking individual conversations

What is a responsibility of transport layer protocols?

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

What is a socket?

sliding window

What is the TCP mechanism used in congestion avoidance?

0 to 1023

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

to keep track of multiple conversations between devices

What is the purpose of using a source port number in a TCP communication?

applications that are sensitive to delay

What type of applications are best suited for using UDP?

The client randomly selects a source port number

Which action is performed by a client when establishing communication with a server via the use of UDP at the transport layer?

192.168.1.1:80

Which number or set of numbers represents a socket?

TCP 3-way handshake

Which transport layer feature is used to guarantee session establishment?

ACK SYN

Which two flags in the TCP header are used in a TCP three-way handshake to establish connectivity between two network devices? (Choose two.)

-acknowledging receiving data -re-transmitting any unacknowledged data

Which two operations are provided by TCP but not by UDP? (Choose two.)

DNS VOIP

Which two services or protocols use the preferred UDP protocol for fast transmission and low overhead? (Choose two)
