Tcp — Cisco CCNA (200-301) Practice Questions
TCP (Transmission Control Protocol) is a connection-oriented, reliable transport-layer protocol that uses a three-way handshake, sequencing, acknowledgment, and flow control to ensure ordered and error-checked delivery of data. The CCNA 200-301 exam requires candidates to understand how TCP establishes and tears down sessions, how windowing and flow control work, and how TCP differs from UDP in terms of reliability and overhead. TCP is foundational to understanding application-layer protocols such as HTTP, HTTPS, FTP, and SSH, all of which appear on the exam. Questions often ask candidates to identify TCP characteristics or choose the appropriate transport protocol for a given scenario.
