Posted by: Pdfprep Category: 70-480 Tags: , ,

You are developing an application that consumes an external web service that returns the latest stock rate.

The application has two methods:

• The getResults() method makes an AJAX web service request

• The ShowRate() method displays the stock rate from the web service response

You need to ensure that the ShowRate() method always displays the latest stock rate.

Which code segment should you use?

A . Option A
B . Option B
C . Option C
D . Option D

Answer: D


“always displays the latest stock rate ". Should use cache: false

Note: cache (default: true, false for dataType ‘script’ and ‘jsonp’)

Type: Boolean

If set to false, it will force requested pages not to be cached by the browser.

Reference: jQuery.ajax()
