Zorluk: OrtaConnection-Oriented vs Connectionless Protocols

A network administrator is deploying a real-time environmental sensor telemetry application across a corporate subnet. The application requires low-latency transmission of periodic status readings where lost updates are immediately superseded by newer readings and do not require retransmission. Which transport layer protocol characteristic best satisfies these operational requirements?

  1. User Datagram Protocol (UDP) due to its connectionless overhead structure and lack of delivery acknowledgment mechanisms.Cevap
  2. B
    Transmission Control Protocol (TCP) due to its connection-oriented session establishment and windowing flow control.
  3. C
    Internet Protocol (IP) due to its Layer 3 connectionless framing and path routing capabilities.
  4. D
    Secure Shell (SSH) using port 22 to manage connectionless delivery of stream telemetry.

Cevap

User Datagram Protocol (UDP) due to its connectionless overhead structure and lack of delivery acknowledgment mechanisms.
User Datagram Protocol (UDP) is a connectionless transport protocol that operates without establishing a prior session, maintaining state, or performing error recovery. Because real-time telemetry updates are frequent and superseded by subsequent readings, UDP's minimal header overhead and lack of retransmission delay make it the optimal choice.

Adım Adım Çözüm

1
Identify the application requirements specified in the scenario.
The application requires low latency, minimal overhead, and can tolerate dropped packets without retransmission.
Real-time streaming and telemetry applications prioritize immediate data arrival over complete data recovery.
2
Evaluate transport layer protocols against these requirements.
UDP operates without a connection handshake, sequence numbers, or acknowledgment mechanisms.
Connectionless protocols eliminate the latency associated with session setup and automatic retransmission of lost packets.
3
Select the protocol characteristic that matches the requirement.
UDP provides connectionless transmission ideal for latency-sensitive telemetry.
TCP would introduce latency through flow control and retransmissions, while IP operates at Layer 3 rather than Layer 4.
