Which three web applications work best when they are designed to be server-push enabled?
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
C can also be true not sure how to choose between them
I would have probably not said A since it says “frequent updates” and not “live updates”. From https://en.wikipedia.org/wiki/Web_feed: “Web feeds are an example of pull technology, although they may appear to push content to the user”
D is not correct because JMS does not guarantee when the message will be delivered. The bidding might be over until the message is delivered so a more connected apraoch is desired for D.
C is more correct than D
