Java SE 7 Programmer II — Question 2

Which three web applications work best when they are designed to be server-push enabled?

Answer options

• A. A news feed used for providing users with frequently updated news content
• B. A web chat that allows users to communicate using easily accessible web interfaces
• C. A live sporting event application, used to deliver current results during matches
• D. An auction system that provides users with live online bidding
• E. A graphics rendering application that generates visuals in an orderly fashion

Correct answer: A, B, D

Explanation

The correct options A, B, and D are all applications that benefit from real-time updates, making server-push functionality essential for delivering timely information. Option C, while also time-sensitive, is not as interactive as the others, and Option E does not require continuous updates, as it focuses on generating visuals rather than ongoing data delivery.
