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?
answer
transport
question
What are three responsibilities of the transport layer? (Choose three.)
answer
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.
question
What is an advantage of TCP over UDP?
answer
TCP communication is more reliable.
question
What is the purpose of using a source port number in a UDP communication?

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

- Length
- Source Port
question
Which number or set of numbers represents a socket?
answer
192.168.1.1:80
question
Which transport layer feature is used to guarantee session establishment?
answer
TCP 3-way handshake
question
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.)
answer
step 1 client sends FIN
step 2 server sends ACK
step 3 server sends FIN
step 4 client sends ACK
question
What is the purpose of the TCP sliding window?
answer
to request that a source decrease the rate at which it transmits data.
question
Which action is performed by a client when establishing communication with a server via the use of UDP at the transport layer?
answer
The client randomly selects a source port number.
question
What type of applications are best suited for using UDP?
answer
applications that are sensitive to delay.
question
Which two services or protocols use the preferred UDP protocol for fast transmission and low overhead? (Choose two)
answer
1- DNS
2- VoIP
question
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.)
Which TCP/IP model layer is closest to the end user?
answer
application
question
Which three protocols or standards are used at the application layer of the TCP/IP model? (Choose three.)
answer
1- HTTP
2- GIF
3- MPEG
question
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?
answer
peer-to-peer (P2P)
question
What is true about a client-server network?
answer
The network includes a dedicated server.
question
Which protocol can be used to transfer messages from an email server to an email client?
answer
POP3
question
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.)
answer
1- DNS server
2-default gateway
question
On a home network, which device is most likely to provide dynamic IP addressing to clients on the home network?
answer
a home router
question
Why is DHCP preferred for use on large networks?
answer
It is a more efficient way to manage IP addresses than static address assignment.
question
