Cisco chapter 9 & 10

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

- Checksum - Length - Source Port

Which protocol can be used to transfer messages from an email server to an email client?

POP3

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.)

step 1 client sends FIN step 2 server sends ACK step 3 server sends FIN step 4 client sends ACK

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

1- DNS 2- VoIP

A user is attempting to access http://www.cisco.com/ without success. Which two configuration values must be set on the host to allow this access? (Choose two.)

1- DNS server 2-default gateway

Which three protocols or standards are used at the application layer of the TCP/IP model? (Choose three.)

1- HTTP 2- GIF 3- MPEG

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

1- meeting the reliability requirements of applications, if any. 2- multiplexing multiple communication streams from many users or applications on the same network. 3- identifying the applications and services on the client and server that should handle transmitted data.

Which three layers of the OSI model provide similar network services to those provided by the application layer of the TCP/IP model? (Choose three.)

1- presentation layer 2- application layer 3- session layer

Which number or set of numbers represents a socket?

192.168.1.1:80

Why is DHCP preferred for use on large networks?

It is a more efficient way to manage IP addresses than static address assignment.

Which transport layer feature is used to guarantee session establishment?

TCP 3-way handshake

What is an advantage of TCP over UDP?

TCP communication is more reliable.

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

The client randomly selects a source port number.

What is true about a client-server network?

The network includes a dedicated server.

On a home network, which device is most likely to provide dynamic IP addressing to clients on the home network?

a home router

Which TCP/IP model layer is closest to the end user?

application

What type of applications are best suited for using UDP?

applications that are sensitive to delay.

A wired laser printer is attached to a home computer. That printer has been shared so that other computers on the home network can also use the printer. What networking model is in use?

peer-to-peer (P2P)

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

to keep track of multiple conversations between devices.

What is the purpose of the TCP sliding window?

to request that a source decrease the rate at which it transmits data.

What OSI layer is responsible for establishing a temporary communication session between two applications and ensuring that transmitted data can be reassembled in proper sequence?

transport

True or False? In FTP transactions, an FTP client uses the pull method to download files from an FTP server.
