Implementing and Configuring Cisco Identity Services Engine (SISE) — Question 231

What is a characteristic of the UDP protocol?

Answer options

• A. UDP can detect when a server is down.
• B. UDP can detect when a server is slow.
• C. UDP offers best-effort delivery.
• D. UDP offers information about a non-existent server.

Correct answer: C

Explanation

The correct answer is C because UDP is a connectionless protocol that provides best-effort delivery without guarantees of reliability or order. Options A and B are incorrect as UDP does not provide mechanisms for detecting server statuses or performance. Option D is also incorrect since UDP does not convey information about non-existent servers.
