Question 61

Universal Containers wants to assess the advantages of declarative development versus programmatic customization for specific use cases in its Salesforce implementation.
What are two characteristics of declarative development over programmatic customization?
Choose 2 answers

Correct Answer: C,D
Declarative Development refers to building applications using Salesforce's point-and-click tools without writing code. It has several characteristics:
Option C: Declarative development does not require Apex test classes.
True.
Declarative tools like Flows, Process Builder, and Validation Rules do not require Apex test classes because they are configured via the UI and not through code.
Reference:
Option D: Declarative development can be done using the Setup menu.
True.
Declarative development is performed within the Setup menu in Salesforce, where administrators and developers can create objects, fields, automation, and more using point-and-click tools.
Options Not Applicable:
Option A: Declarative code logic does not require maintenance or review.
False.
Even declarative logic requires maintenance, especially when business requirements change.
Regular review is necessary to ensure that automation processes continue to meet organizational needs.
Option B: Declarative development has higher design limits and query limits.
False.
Declarative processes have limits, and sometimes programmatic solutions can handle larger data volumes or more complex processing.
For example, Apex can handle more records in a loop than a Flow.
Conclusion:
The characteristics of declarative development over programmatic customization are C and D.

Question 64

How is a controller and extension specified for a custom object named "Notice" on a Visualforce page?

Correct Answer: D
When creating a Visualforce page that uses a standard controller and a controller extension for a custom object named Notice__c, the correct syntax is:
<apex:page standardController="Notice__c" extensions="myControllerExtension"> Option D: apex standardController="Notice__c" extensions="myControllerExtension" Correct Syntax.
standardController attribute specifies the standard controller for the custom object Notice__c.
extensions attribute specifies the name of the Apex class myControllerExtension that extends the functionality of the standard controller.
Reference:
Options Not Applicable:
Option A: apex
controller="Notice__c" extensions="myControllerExtension"
Incorrect.
The controller attribute is used for custom controllers, not standard controllers.
Option B and C:
Syntax errors and incorrect attributes make these options invalid.
Conclusion:
The correct way to specify a controller and extension for the Notice__c object is Option D.

Question 65

A developer completed modifications to a customized feature that is comprised of two elements:
* Apex trigger
* Trigger handler Apex class
What are two factors that the developer must take into account to properly deploy the modification to the production environment?
Choose 2 answers

Correct Answer: B,D
When deploying Apex code to a production environment, certain requirements must be met regarding test coverage and annotations.
Option B: Apex classes must have at least 75% code coverage org-wide.
Correct Requirement.
Salesforce requires that all Apex classes and triggers have a combined code coverage of at least 75% before deployment to production.
This means that, across all Apex code in the org, at least 75% of the code must be covered by test methods.
Every trigger must have some test coverage, even if the overall code coverage is above 75%.
Specifically, triggers must have at least 1% code coverage.
Test methods should be annotated with @isTest.
However, it's not mandatory that all methods in a test class use @isTest; helper methods within test classes can be private or public methods without the annotation.
Only the test methods themselves need the @isTest annotation.
The testMethod keyword is deprecated but still supported.
The preferred approach is to use the @isTest annotation.
Using testMethod is not recommended for new code.
Reference:
Code Coverage Requirement
Option D: At least one line of code must be executed for the Apex trigger.
Correct Requirement.
Trigger Coverage Requirement
Options Not Suitable:
Option A: All methods in the test classes must use @isTest.
Partially Correct.
Defining Test Methods
Option C: Test methods must be declared with the testMethod keyword.
Outdated Practice.
Deprecated testMethod Keyword
Conclusion:
The two factors the developer must take into account are B (75% code coverage org-wide) and D (At least 1% coverage for triggers).
These are mandatory requirements for deploying Apex code to production.
