CompTIA Network+ (N10-008) — Question 253

Which of the following OSI model layers is where a technician would view UDP information?

Answer options

• A. Physical
• B. Data link
• C. Network
• D. Transport

Correct answer: D

Explanation

The correct answer is D, Transport, as UDP (User Datagram Protocol) operates at this layer, which is responsible for end-to-end communication and data flow control. The other layers, Physical, Data link, and Network, do not handle transport layer protocols like UDP.
