Zorluk: KolayTCP vs UDP Comparison and Protocols

A network technician is evaluating transport layer requirements for real-time application traffic. Which two features are characteristic of the User Datagram Protocol (UDP) rather than the Transmission Control Protocol (TCP)? (Select two.)

  1. Low fixed header size of 8 bytesCevap
  2. B
    Guaranteed sequence delivery using acknowledgment numbers
  3. Connectionless datagram delivery without handshake overheadCevap
  4. D
    Dynamic flow control managed through sliding window adjustments

Cevap

The characteristics unique to UDP are its low fixed header size of 8 bytes and its connectionless datagram delivery without handshake overhead.
The correct features of UDP are its minimal 8-byte header length and connectionless nature, which avoids connection setup delays.

Adım Adım Çözüm

1
Identify transport layer protocol overhead differences
UDP relies on a simple 8-byte header (Source Port, Destination Port, Length, Checksum), whereas TCP requires a minimum 20-byte header.
Understanding header structure helps evaluate bandwidth and processing efficiency.
2
Evaluate connection state properties
UDP operates connectionlessly without requiring a initial three-way handshake.
Connectionless delivery minimizes latency for real-time applications.

Anahtar Kavram

UDP is a lightweight, connectionless transport layer protocol with minimal header overhead (8 bytes) and no built-in flow control or reliability mechanisms.
