HPE Aruba Certified Central Associate (ACCA) — Question 51

Which attributes are true about UDP? (Choose two.)

Answer options

• A. connectionless
• B. requires an established connection
• C. used for latency-sensitive traffic
• D. uses sequence numbers
• E. supports retransmission

Correct answer: A, C

Explanation

UDP is connectionless (A), meaning it does not require a dedicated end-to-end connection before sending data, which is ideal for applications that prioritize speed. It is also utilized for latency-sensitive traffic (C), such as online gaming or streaming, where timely delivery is more critical than guaranteed delivery. The other options (B, D, E) are characteristics of connection-oriented protocols like TCP, which requires a connection and ensures data reliability through sequence numbers and retransmission.
