You are developing an application that uses many small images for various aspects of the interface.
The application responds slowly when additional resources are being accessed.
You need to improve the performance of the application.
What should you do?
A.
Preload all the images when the client connects to ensure that the images are cached.
B.
Combine all the images into a single image and use CSS to create sprites.
C.
Host all images on an alternate server and provide a CDN.
D.
Convert the images to .png file format and stream all images on a single connection.
It should be B.

Are you 100% sure that the answer is B
In most of the other dumps,answer is C . I think B is also correct as shown by Tantra.
Please Admin give us the correct answer
I think B is correct – minimizing the number of HTTP requests (for all the images) is going to give better performance over a CDN
The question is, if the bottleneck is on the client side or on the server side.
For the first case I would say that B is the correct answer.
For the second case answer C would be the better choice.
