Zorluk: OrtaConnection-Oriented vs Connectionless Protocols

A systems engineer is reviewing the transport protocol requirements for an industrial telemetry network. The architecture requires real-time broadcast of environmental sensor data where minimal delay is critical and minor packet loss is tolerable. Simultaneously, the system requires a mechanism to push critical firmware updates to remote controllers where every packet must be delivered accurately and in order. Which of the following statements correctly describe the characteristics and transport protocol choices appropriate for this deployment? (SELECT TWO)

  1. UDP is preferred for the real-time sensor stream because its connectionless nature reduces protocol overhead and transmission latency.Cevap
  2. TCP is necessary for firmware pushes because connection-oriented mechanisms guarantee data delivery, ordering, and integrity verification.Cevap
  3. C
    UDP guarantees packet delivery for the sensor data by retransmitting missing datagrams at the Transport layer whenever packet loss occurs.
  4. D
    TCP establishes communication using a lightweight two-way handshake that omits acknowledgement tracking to minimize delay.
  5. E
    TCP and UDP operate at Layer 3 of the OSI model to provide logical IP addressing and path determination across network segments.

Cevap

UDP is preferred for the real-time sensor stream due to its lower overhead and connectionless nature, while TCP is necessary for firmware updates to guarantee reliable, ordered delivery.
The choice emphasizing UDP for real-time sensor streaming is correct because connectionless communications do not spend cycles on connection management or retransmissions, maximizing throughput and minimizing latency. The choice identifying TCP for firmware updates is correct because connection-oriented protocols provide error checking, sequencing, and delivery verification mandatory for sensitive code deployments.

Adım Adım Çözüm

1
Analyze the real-time sensor metric streaming requirement.
Real-time streaming requires low overhead and minimal latency; unacknowledged lost data is acceptable. This aligns with User Datagram Protocol (UDP).
UDP operates connectionlessly without handshake or retransmission overhead.
2
Analyze the firmware update requirement.
Firmware updates require strict data integrity, packet sequencing, and guaranteed arrival. This aligns with Transmission Control Protocol (TCP).
TCP provides reliable, connection-oriented data transfer through sequence numbers, acknowledgements, and retransmissions.
3
Evaluate distractor choices for protocol characteristics and layer placement.
Statements claiming UDP handles automatic retransmission, TCP uses a two-way handshake without acknowledgements, or that either protocol operates at Layer 3 are incorrect.
UDP lacks Layer 4 retransmissions, TCP relies on a 3-way handshake with acknowledgements, and both protocols belong strictly to OSI Layer 4.
