Zorluk: KolayTCP vs UDP Comparison and Protocols

A network administrator is evaluating transport layer options for application traffic. Which two characteristics accurately describe User Datagram Protocol (UDP)? (Select two.)

  1. It operates as a connectionless protocol without establishing a session prior to data transmissionCevap
  2. It maintains a fixed 8-byte header to keep processing overhead lowCevap
  3. C
    It ensures reliable in-order datagram delivery using sequence numbers
  4. D
    It regulates sender transmission speed using a dynamic sliding window mechanism

Cevap

User Datagram Protocol (UDP) is connectionless and features an 8-byte header overhead.
The correct responses highlight UDP's core design as a lightweight, connectionless protocol. UDP sends datagrams without a three-way handshake and uses an 8-byte header containing source port, destination port, length, and checksum fields.

Adım Adım Çözüm

1
Analyze transport layer requirements and connection states.
Identify that UDP is a stateless, connectionless protocol that transmits data without initiating a preliminary handshake.
UDP avoids the setup latency required by connection-oriented protocols like TCP.
2
Compare protocol header sizes and operational mechanisms.
Confirm that the UDP header requires only 8 bytes of overhead, compared to TCP's 20-byte baseline header.
A small header minimizes network overhead and speeds up datagram parsing for real-time applications.
