JNCIA-Junos: Juniper Networks Certified Associate – Junos (2024) — Question 19

What are two attributes of the UDP protocol? (Choose two.)

Answer options

• A. UDP is best effort.
• B. UDP is always slower than TCP.
• C. UDP is connectionless.
• D. UDP is more reliable than TCP.

Correct answer: A, C

Explanation

The correct answers are A and C because UDP is known as a best-effort protocol that does not guarantee delivery, making it connectionless. Options B and D are incorrect as UDP can be faster than TCP due to its lack of connection overhead and is not more reliable than TCP, which provides error recovery and guarantees delivery.
