NEW QUESTION # 84
Universal Container* decides to use purely declarative development to build out a new Salesforce application.
Which two options can be used to build out the business logic layer for this application?
Choose 2 answer
Answer: B,D
Explanation:
* Validation Rules. This is true because validation rules are a declarative way of enforcing data quality and business logic on the Salesforce objects. Validation rules can prevent users from saving records that do not meet certain criteria, such as required fields, unique values, or custom formulas1.
* Record-Triggered Flow. This is true because record-triggered flows are a declarative way of automating business processes and logic on the Salesforce objects. Record-triggered flows can perform actions such as creating, updating, or deleting records, sending emails, or calling Apex classes when a record is created, updated, or deleted2.
* Remote Actions. This is false because remote actions are a programmatic way of invoking Apex methods from Visualforce pages or Lightning components. Remote actions require writing Apex code and using the @RemoteAction annotation to expose the methods to the client-side3.
* Batch Jobs. This is false because batch jobs are a programmatic way of processing large sets of data or records in batches using Apex. Batch jobs require writing Apex code and implementing the
* Database.Batchable interface to define the start, execute, and finish methods of the job.

NEW QUESTION # 85
A developer has a Visualforce page and custom controller to save Account records. The developer wants to display any validation rule violations to the user.
How can the developer make sure that validation rule violations are displayed?
Answer: A
Explanation:
When saving records using a custom controller in a Visualforce page, validation rule violations can occur. To display these validation error messages to the user, the developer should use the <apex:messages> component.
Option A: Include <apex:messages> on the Visualforce page.
Correct Approach.
The <apex:messages> component displays all messages that were generated for all components on the page, including validation rule violations.
When a DML operation is performed, any validation errors are automatically added to the ApexPages message collection.
Including <apex:messages> in the page ensures that these messages are displayed to the user.
Example:
<apex:page controller="CustomAccountController">
<apex:form>
<apex:messages />
<!-- Form fields for Account -->
<apex:commandButton action="{!saveAccount}" value="Save" />
</apex:form>
</apex:page>
While a try/catch block can catch exceptions, it is not required for displaying validation errors.
Validation rule violations are added to the message collection automatically.
Using try/catch may suppress the standard error handling.
Option C: Add custom controller attributes to display the message.
Inefficient Approach.
Manually adding controller attributes and logic to handle error messages adds unnecessary complexity.
The standard <apex:messages> component handles this automatically.
Option D: Perform the DML using the Database.upsert() method.
Not Sufficient Alone.
Using Database.upsert() allows for finer control over DML operations and error handling.
However, unless the errors are added to the message collection, they will not be displayed.
The developer would still need to handle displaying the errors.
Conclusion:
By including the <apex:messages> component on the Visualforce page, validation rule violations and other error messages are displayed to the user automatically.
Therefore, Option A is the correct answer.

Not Necessary.
