JNCIA-Junos: Juniper Networks Certified Associate – Junos (2022) — Question 28

What are two functions of the transport layer? (Choose two.)

Answer options

• A. data integrity
• B. packet forwarding
• C. flow control
• D. segmentation

Correct answer: A, D

Explanation

The correct answers are A and D because the transport layer is responsible for ensuring data integrity through error detection and correction, as well as segmentation, which breaks down large messages into smaller packets for efficient transmission. Options B and C are functions associated with the network layer and data link layer, respectively, and not primary functions of the transport layer.
