Zorluk: KolayConnection-Oriented vs Connectionless Protocols

A network technician is reviewing transport layer protocols to determine their functional differences. Which of the following characteristics are specific to connection-oriented protocols such as TCP, rather than connectionless protocols such as UDP? (SELECT TWO)

  1. Guaranteed data delivery through acknowledgments and sequence trackingCevap
  2. Connection establishment via a formal three-way handshake prior to data transmissionCevap
  3. C
    Minimal header overhead optimized for real-time low-latency transmission
  4. D
    Operations conducted primarily at Layer 3 (Network Layer) of the OSI model
  5. E
    Stateless datagram transmission without maintaining connection state information

Cevap

The correct characteristics of connection-oriented protocols are guaranteed data delivery through acknowledgments and sequence tracking, as well as connection establishment via a formal three-way handshake prior to data transmission.
Connection-oriented protocols like TCP guarantee data delivery by acknowledging received segments and retransmitting lost packets. Furthermore, they establish an explicit logical connection before transmitting payload data using a three-way handshake (SYN, SYN-ACK, ACK).

Adım Adım Çözüm

1
Identify the protocol operational model
Connection-oriented protocols establish a dedicated session state and verify receipt of data.
Understanding the fundamental goal of TCP versus UDP identifies key feature differences.
2
Evaluate protocol mechanisms
TCP uses a SYN, SYN-ACK, ACK three-way handshake to initiate sessions and relies on sequence numbers/acknowledgments for guaranteed delivery.
These mechanisms explicitly define connection-oriented operations.
