JNCIA-Junos: Juniper Networks Certified Associate – Junos (2022) — Question 13

What are two characteristics of UDP? (Choose two.)

Answer options

• A. UDP operates at the transport layer.
• B. UDP is connection-oriented.
• C. UDP packets are sent best-effort.
• D. UDP is more reliable than TCP.

Correct answer: A, C

Explanation

The correct answer includes A and C because UDP indeed operates at the transport layer and utilizes a best-effort delivery system, meaning it does not guarantee packet delivery. Options B and D are incorrect as UDP is connectionless, not connection-oriented, and it is not more reliable than TCP, which provides error checking and guarantees delivery.
