ITF - Quiz 9.2 - TCP/IP

What is the purpose of the Transmission Control Protocol/Internet Protocol (TCP/IP) suite?

• To connect military sites

• To establish a research network

• To provide apps and services

• To connect refrigerators to the internet

What is the main advantage of packet switching over direct channel communication?

• Packet switching is more reliable

• Packet switching allows for automatic recovery from failures

• Packet switching requires less bandwidth

• Packet switching provides faster communication

What is the function of a router in packet switching?

• To label packets with source and destination addresses

• To forward packets to their intended destination

• To divide data into small chunks or packets

• To establish a direct channel between computers

Why is a packet switching protocol considered robust?

• It can automatically recover from communication link failures

• It can utilize any available network path

• It can re-route data packets

• All of the above

What happens if some packets are lost or damaged during transmission in packet switching?

• The entire message needs to be retransmitted

• Only the lost or damaged packets need to be resent

• The transmission is terminated

• The packets are automatically repaired

Which layer of the TCP/IP model is responsible for placing frames onto the physical network?

• Link or Network Interface layer

• Internet layer

• Transport layer

• Application layer

What is the main protocol in the TCP/IP suite responsible for logical addressing and routing of packets?

• Internet Protocol (IP)

• Address Resolution Protocol (ARP)

• Internet Control Message Protocol (ICMP)

• Transmission Control Protocol (TCP)

Which transport protocol provides connection-oriented delivery in the TCP/IP suite?

• Transmission Control Protocol (TCP)

• User Datagram Protocol (UDP)

• Internet Protocol (IP)

• Address Resolution Protocol (ARP)

What is the advantage of using User Datagram Protocol (UDP) over Transmission Control Protocol (TCP)?

• UDP provides reliable delivery

• UDP guarantees correct sequence of packets

• UDP has less processing and transmission overhead

• UDP is slower than TCP

Which layer of the TCP/IP model contains protocols that provide the communications formats for exchanging data between hosts?

• Link or Network Interface layer

• Internet layer

• Transport layer

• Application layer
