NEW QUESTION # 26
A corporation has many different Salesforce orgs, with some different objects and some common objects, and wants to build a single Java application that can create, retrieve, and update common object records in all of the different orgs.
Which method of integration should the application use?
Answer: C

NEW QUESTION # 28
A developer needs to implement a system audit feature that allows users, assigned to a custom profile named "Auditors", to perform searches against the historical records in the Account object. The developer must ensure the search is able to return history records that are between 6 and 12 months old.
Given the code below, which select statement should be inserted below as a valid way to retrieve the Account History records ranging from 6 to 12 months old?
A)
B)
C) D)
Answer: B
Explanation:
Given the code snippet, the correct query to retrieve Account History records between 6 and 12 months old would be the one that includes a WHERE clause filtering records where the CreatedDate is greater than or equal to initialDate and less than or equal to endDate. Option B's statement does this correctly by using the >= and <= operators to define the range between initialDate (which is set to today's date minus 12 months) and endDate (set to today's date minus 6 months). Options A, C, and D either use incorrect comparison operators or compare against the wrong variables, resulting in an incorrect data set being returned.

NEW QUESTION # 29
Refer to the exhibit
Users of this Visualforce page complain that the page does a full refresh every time the Search button Is pressed. What should the developer do to ensure that a partial refresh Is made so that only the section identified with opportunity List is re-drawn on the screen?
Answer: D
Explanation:
To ensure that only a part of the Visualforce page is refreshed, developers can use the reRender attribute of the <apex:commandButton> tag. This attribute specifies the IDs of the components that should be re-rendered as a result of the action method being completed. In this case, setting the reRender attribute to the ID of the <apex:pageBlockSection> that contains the opportunity list will cause only that section to be updated on the page, resulting in a partial page refresh.
The correct answer is B because it uses the reRender attribute correctly to update only the specific part of the page (opportunityList) without a full page refresh.
