NEW QUESTION # 95
Which three Visualforce components can be used to initiate Ajax behavior to perform partial page updates?
Choose 3 answers
Answer: A,B,E
Explanation:
The three Visualforce components that can be used to initiate Ajax behavior to perform partial page updates are apex:commandLink, apex:commandButton, and apex:actionSupport. These components allow the developer to invoke an Apex controller method or a JavaScript function, and specify a apex:actionStatus or a apex:reRender attribute to update a part of the page without refreshing the whole page. The apex:commandLink and apex:commandButton components render as HTML links or buttons, respectively, and can be used to trigger an action when the user clicks on them. The apex:actionSupport component can be used to add Ajax support to any other component, and can be used to trigger an action when the user performs an event, such as mouseover, change, or blur. The apex:form component is not a valid answer, as it is used to enclose the components that need to interact with the server, but it does not initiate Ajax behavior by itself. The apex:actionStatus component is not a valid answer, as it is used to display the status of an Ajax request, such as a loading message or a spinner, but it does not initiate Ajax behavior by itself.

NEW QUESTION # 96
A developer created an Opportunity trigger that updates the account rating when an associated opportunity is considered high value. Current criteria for an opportunity to be considered high value is an amount greater than or equal to $1,000,000. However, this criteria value can change over time.
There is a new requirement to also display high value opportunities in a Lightning web component.
Which two actions should the developer take to meet these business requirements, and also prevent the business logic that obtains the high value opportunities from being repeated in more than one place?
Choose 2 answers
Answer: A,C
Explanation:
To meet the business requirements and prevent the business logic that obtains the high value opportunities from being repeated in more than one place, the developer should take two actions: create a helper class that fetches the high value opportunities, and use custom metadata to hold the high value amount. By creating a helper class, the developer can encapsulate the logic that queries the opportunities based on the high value amount, and reuse the same class in both the trigger and the Lightning web component. By using custom metadata, the developer can store the high value amount as a configurable value that can be retrieved by the helper class, and avoid hard-coding the value in the code. This way, the developer can also easily change the value in the future without modifying the code. Calling the trigger from the Lightning web component would not work, as triggers are not meant to be invoked directly from the user interface, and would also violate the separation of concerns principle. Leaving the business logic code inside the trigger for efficiency would not work, as it would create code duplication and maintenance issues when the same logic is needed in the Lightning web component.

NEW QUESTION # 97
Java
@isTest
static void testUpdateSuccess() {
Account acet = new Account(Name = 'test');
insert acet;
// Add code here
extension.inputValue = 'test';
PageReference pageRef = extension.update();
System.assertNotEquals(null, pageRef);
}
What should be added to the setup, in the location indicated, for the unit test above to create the controller extension for the test?
Answer: C
Explanation:
123
To properly test a Visualforce Controller Extension in Apex, the developer must replicate the instantiation process used by the Lightning Platform at runtime. A4 controller extension is a class whose constructor is specifically defined to accept a single parameter of the type ApexPages.StandardController. 5The standard controller acts as the bridge b6etween the custom extension logic and the underlying Salesforce record (in this case, an Account).
In the provided test method, a record acet has been inserted into the database. To create the extension object, the developer must first instantiate the StandardController by passing the acet SObject record into its constructor. Once the standard controller instance (e.g., sc) is created, it is then passed into the constructor of the AccountControllerExt class. Option B is the correct implementation of this two-step pattern. Option C is incorrect because the StandardController constructor requires a full SObject record, not just an ID string.
Options A and D are incorrect because extension classes do not support constructors that take an SObject or an ID directly; they specifically require the StandardController object to provide the necessary context for standard actions and fields. Following the correct pattern ensures the test accurately simulates the page execution context.
NEW QUESTION # 98
A Visualforce page contains an industry select list and displays a table of Accounts that have a matching value in their Industry field.
When a user changes the value in the industry select list, the table of Accounts should be automatically updated to show the Accounts associated with the selected industry.
What is the optimal way to implement this?
Answer: D
