Transport Layer — Cisco CCNA (200-301) Practice Questions
The transport layer is Layer 4 of the OSI model and is responsible for end-to-end communication, segmentation, flow control, and multiplexing of application data streams using port numbers. On the CCNA 200-301 exam, candidates must understand the roles and differences of the two primary transport-layer protocols, TCP and UDP, and know which well-known port numbers correspond to common applications. The transport layer is also where concepts like windowing, acknowledgments, and connection establishment are examined. A clear understanding of Layer 4 is necessary for interpreting packet captures and troubleshooting application connectivity.
