AWS Certified Advanced Networking – Specialty (ANS-C00) — Question 174

Within the TCP/IP model what is the name of the Packet Data Unit (PDU) used between Transport Layers for communication between sender and receiver

Answer options

• A. Frames
• B. Packets
• C. Data
• D. Segments

Correct answer: D

Explanation

The correct answer is D, Segments, because in the TCP/IP model, the PDU at the Transport Layer is referred to as a segment. The other options—Frames, Packets, and Data—refer to PDUs at different layers; Frames are used at the Data Link layer, Packets at the Network layer, and Data is a more general term not specific to a particular layer.
