Choosing a TCP characteristic | LPIC-1 102-500 Exam original practice question

109.1Standard

Compare the transport characteristics of TCP and UDP.

Which statement describes TCP?

Hint 1: Focus on the requirement

Identify what must change and what must remain unchanged. Then choose the command whose scope matches that requirement.

Hint 2: Check each command's role

Separate commands that display information, change state, remove data, or affect a child process.

接続確立を行わず、各datagramの到達と順序を保証する: Incorrect. It combines connectionless behavior with guarantees.
IP addressを自動配布するapplication protocolである: Incorrect. Address assignment is a DHCP function.
connection-orientedで、byte streamの順序制御と再送を行う: Correct. This describes TCP's reliable byte-stream transport.
network層でerror通知だけを運ぶprotocolである: Incorrect. ICMP is a network-control protocol, not TCP.

Detailed explanation

Incorrect接続確立を行わず、各datagramの到達と順序を保証する

Incorrect. It combines connectionless behavior with guarantees.

IncorrectIP addressを自動配布するapplication protocolである

Incorrect. Address assignment is a DHCP function.

Correctconnection-orientedで、byte streamの順序制御と再送を行う

Correct. This describes TCP's reliable byte-stream transport.

Incorrectnetwork層でerror通知だけを運ぶprotocolである

Incorrect. ICMP is a network-control protocol, not TCP.

An example you can run in a temporary verification environment.

printf '%s
' 'TCP: connection-oriented ordered byte stream retransmission'

TCP: connection-oriented ordered byte stream retransmission

Foundation review

Check whether the command acts on the current shell, a new process, an existing process, or a file.

Use the supplied command and compare the output with the expected result.
