Transport Layer Concepts Quiz

What is the primary role of the transport layer?

• To encrypt data for security

• To provide logical communication between application processes

• To manage physical connections

• To route data between networks

Which protocol is known for providing reliable communication?

• Internet Control Message Protocol (ICMP)

• Hypertext Transfer Protocol (HTTP)

• User Datagram Protocol (UDP)

• Transmission Control Protocol (TCP)

What does multiplexing in the transport layer allow?

• Multiple devices to connect to the internet

• Multiple applications to send data simultaneously

• Multiple networks to communicate

• Multiple protocols to be used at once

What is a key characteristic of UDP?

• It is slower than TCP

• It is used for real-time applications

• It requires a connection to be established before data transfer

• It guarantees data delivery

What is the purpose of the UDP checksum?

• To manage flow control

• To establish a connection

• To detect errors in transmitted data

• To ensure data is encrypted

How does the transport layer interact with the network layer?

• It routes data between different networks

• It delivers data to the correct process

• It encrypts data for security

• It manages physical connections

What does segmentation in the transport layer do?

• Encrypts data for security

• Divides large messages into smaller segments

• Combines multiple messages into one

• Routes data to different networks

What is flow control in the context of the transport layer?

• Routing data to the correct destination

• Encrypting data for security

• Establishing a connection between devices

• Managing the speed of data transmission

Which layer does the transport layer sit between in the OSI model?

• Application layer and Data link layer

• Physical layer and Network layer

• Session layer and Presentation layer

• Network layer and Application layer

What happens if a packet is lost in a UDP transmission?

• The system requests a retransmission

• The connection is terminated

• The packet is retransmitted automatically

• The packet is discarded without retransmission
