A+ 1101 Mod 5 Part 1

What is the primary function of the Transmission Control Protocol (TCP)?

• To provide unreliable, connectionless communication between devices

• To facilitate reliable, connection-oriented communication between devices

• To manage wireless networking protocols

• To compare and contrast network hardware options

Answer explanation

The primary function of the Transmission Control Protocol (TCP) is to facilitate reliable, connection-oriented communication between devices.

Which of the following is NOT a key concept or functionality of TCP?

• A. Connection establishment

• B. Reliability

• C. Flow control

• D. Wireless communication

Answer explanation

The correct choice is D. Wireless communication because it is not a key concept or functionality of TCP, which primarily focuses on connection establishment, reliability, and flow control.

What does TCP provide a set of rules and procedures for?

• A. Establishing and maintaining a reliable data exchange over an IP network

• B. Comparing and contrasting network hardware options

• C. Defining and describing the roles of common network hosts and appliances

• D. Managing wireless networking protocols

Answer explanation

TCP provides a set of rules and procedures for establishing and maintaining a reliable data exchange over an IP network, making option A the correct choice.

Which of the following is a learning objective of the module?

• A. Compare and contrast TCP and UDP applications in enterprise environments

• B. Define and describe the roles of common network hosts and appliances

• C. Compare and contrast network hardware options

• D. All of the above

Answer explanation

The correct answer is D. All of the above because all the listed options are learning objectives of the module.

What does the acronym TCP stand for?

• A. Transmission Control Protocol

• B. Transfer Communication Protocol

• C. Transmission Communication Protocol

• D. Transfer Control Protocol

Answer explanation

The acronym TCP stands for Transmission Control Protocol, making option A the correct choice.

What process does TCP use to connect a client and a server?

• Two-way handshake

• Four-way handshake

• Three-way handshake

• Five-way handshake

Answer explanation

TCP uses a Three-way handshake process to connect a client and a server, establishing a reliable connection by exchanging SYN and ACK packets.

How does TCP ensure reliable data delivery?

• By using encryption

• By using acknowledgments and sequence numbers

• By using compression

• By using data replication

Answer explanation

By using acknowledgments and sequence numbers

What mechanism does TCP implement to prevent overwhelming network resources?

• Error detection

• Flow control

• Data compression

• Encryption

Answer explanation

TCP implements flow control to prevent overwhelming network resources by regulating the rate of data transmission between sender and receiver.

What does TCP use to detect errors in data transmission?

• Sequence numbers

• Acknowledgments

• Checksums

• Flow control

Answer explanation

TCP uses checksums to detect errors in data transmission by verifying the integrity of the data being sent.

What process does TCP follow to gracefully terminate a connection?

• Two-way handshake

• Three-way handshake

• Four-way handshake

• Five-way handshake

Answer explanation

TCP follows a Four-way handshake process to gracefully terminate a connection.
