NEW QUESTION # 181
A credit card company needs to implement the functionality for a service agent to process damaged or stolen credit cards. When the customers call in, the service agent must gather many pieces of information. A developer is tasked to implement this functionality.
What should the developer use to satisfy this requirement in the most efficient manner?

  • A. Approval process
  • B. Lightning Component
  • C. Screen-based flow
  • D. Apex trigger

Answer: C

Explanation:
The requirement is for service agents to gather many pieces of information when processing damaged or stolen credit cards.
Option A: Screen-based Flow
Correct Answer.
A Screen Flow allows developers to build guided, interactive forms that collect information from users.
Flows can have multiple screens, validation rules, and branching logic.
They can be created declaratively without code, making them efficient to implement.
Benefits:
Efficient Development: No need for code.
User-Friendly: Provides a step-by-step interface.
Maintainable: Easy to update as requirements change.
Building a custom Lightning Component requires development effort.
For simple data collection, a Flow is more efficient.
Option C: Approval Process
Incorrect.
Approval Processes are used for routing records for approval, not for gathering information from users.
Option D: Apex Trigger
Incorrect.
Triggers run in the background and are not used for interactive user interfaces.
Conclusion:
The most efficient way to satisfy the requirement is to use a Screen-based Flow, which is Option A.
Reference:

Screen Flows
Incorrect Options:
Option B: Lightning Component
*Possible but Less Efficient.


NEW QUESTION # 182

When the code executes, a DML exception is thrown.
How should a developer modify the code to ensure exceptions are handled gracefully?

  • A. Implement the upset DML statement.
  • B. Implement Change Data Capture.
  • C. Remove null items from the list of Accounts.
  • D. Implement a try/catch block for the DML.

Answer: D

Explanation:
Why a try/catch block is required:
In Salesforce, DML operations such as insert, update, delete, and upsert can throw exceptions due to issues like validation rule violations, field constraints, or sharing rule restrictions.
Using a try/catch block ensures that these exceptions are caught and handled gracefully, preventing the entire transaction from failing.
How to modify the code:
The update statement in the code can be wrapped in a try/catch block to catch and handle any exceptions that occur. For example:
apex
Copy code
public static void insertAccounts(List<Account> theseAccounts) {
try {
for (Account thisAccount : theseAccounts) {
if (thisAccount.website == null) {
thisAccount.website = 'https://www.demo.com';
}
}
update theseAccounts;
} catch (DmlException e) {
System.debug('DML Exception: ' + e.getMessage());
}
}
Why not the other options?
A: Implement the upsert DML statement:
upsert is used to either insert or update records based on an external ID or primary key. It does not inherently handle exceptions.
B: Implement Change Data Capture:
Change Data Capture (CDC) is used for tracking changes to data in real time and is unrelated to handling DML exceptions.
D: Remove null items from the list of Accounts:
While cleaning the input data is a good practice, it does not address the need for exception handling during DML operations.

NEW QUESTION # 183
A developer has a single custom controller class that works with a Visualforce Wizard to support creating and editing multiple subjects. The wizard accepts data from user inputs across multiple Visualforce pages and from a parameter on the initial URL.
Which three statements are useful inside the unit test to effectively test the custom controller?
Choose 3 answers

  • A. insert pageRef.
  • B. Test.setCurrentPage(pageRef);
  • C. String nextPage - controller.save().getUrl();
  • D. ApexPages.CurrentPage().getParameters().put('input', 'TestValue');
  • E. public ExtendedController(ApexPages StandardController cntrl) { }

Answer: B,C,D

Explanation:
To effectively test a custom controller that works with a Visualforce wizard, the unit test should do the following:
* Set the current page to the first page of the wizard using Test.setCurrentPage(pageRef), where pageRef is a PageReference object that points to the page URL. This allows the test to access the page parameters and controller methods for that page1.
* Set the page parameter that the wizard expects using
ApexPages.CurrentPage().getParameters().put('input', 'TestValue'), where 'input' is the name of the parameter and 'TestValue' is the value to be passed. This allows the test to simulate the user input or the initial URL parameter that the wizard uses1.
* Verify the navigation logic of the wizard by checking the URL of the next page after invoking the controller action using String nextPage = controller.save().getUrl(), where controller is an instance of the custom controller class and save() is the action method that returns a PageReference object. This allows the test to assert that the wizard redirects to the correct page based on the input and logic2.
The other options are not useful for testing the custom controller. Option A is incorrect because insert pageRef is not a valid Apex statement. Option C is incorrect because public ExtendedController(ApexPages StandardController cntrl) { } is a constructor for a controller extension, not a custom controller3. References:
