JNCIA-Junos: Juniper Networks Certified Associate – Junos (2024) — Question 72

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

Answer options

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

Correct answer: A, B

Explanation

The correct answers are A and B because UDP is indeed a connectionless protocol that does not establish a connection before sending data (A), and it operates on a best-effort basis without guarantees of delivery (B). Options C and D are incorrect as UDP is not more reliable than TCP, which provides error-checking and delivery guarantees, and it is not always slower than TCP; in many cases, it can be faster due to the lack of overhead.
