NEW QUESTION # 117

NEW QUESTION # 118
Which scenario is valid for execution by unit tests?

A. Set the created date of a record using a system method.
B. Generate a Visualforce PDF with getContentASPDF
C. Execute anonymous Apex as a different user,
D. Load data from a remote site with a callout.

Answer: B

Explanation:
Unit tests in Salesforce are designed to test Apex code functionality and can execute certain operations within the testing context.
Option C: Generate a Visualforce PDF with getContentAsPDF
Reference:
"The getContent and getContentAsPDF PageReference methods can be used in test methods."
- Apex Developer Guide: Testing GET and POST Methods
Why Other Options Are Incorrect:
Option A: Load data from a remote site with a callout
Callouts to external services are not allowed in unit tests unless you use a mock callout framework.
"Test methods can't make callouts to external systems. To test callouts, use mock callouts by either implementing an interface or using static resources."
- Apex Developer Guide: Testing HTTP Callouts
Option B: Execute anonymous Apex as a different user
Executing anonymous Apex isn't possible within a test method, and you can't change the user context arbitrarily in tests except with System.runAs, which doesn't execute as a different user for anonymous code.
"You can use System.runAs to run code as a different user, but you cannot execute anonymous Apex in this way within a test."
- Apex Developer Guide: Running Apex as Another User
Option D: Set the created date of a record using a system method
System fields like CreatedDate are not writeable in Apex tests.
"You can't set values for fields that have the Createable attribute set to false, such as system fields like CreatedDate or LastModifiedDate."
- Apex Developer Guide: DML Statements

NEW QUESTION # 119
A developer must create a ShippingCalculator class that cannot be instantiated and must include a working default implementation of a calculate method, that sub-classes can override.
What is the correct implementation of the ShippingCalculator class?

Answer: D

NEW QUESTION # 120
A developer must provide custom user interfaces when users edit a Contact in either Salesforce Classic or Lightning Experience.
What should the developer use to override the Contact's Edit button and provide this functionality?

A. A Lightning page in Salesforce Classic and a Visualforce page in Lightning Experience
B. A Visualforce page in Salesforce Classic and a Lightning component in Lightning Experience
C. A Visualforce page in Salesforce Classic and a Lightning page in Lightning Experience
D. A Lightning component in 5alesforce Classic and a Lightning component in lightning Experience

Answer: B

Explanation:
To override the Contact's Edit button and provide custom user interfaces in both Salesforce Classic and Lightning Experience, the developer should use a Visualforce page in Salesforce Classic and a Lightning component in Lightning Experience. This is because Visualforce pages are supported as overrides in Salesforce Classic, but not in Lightning Experience or mobile. On the other hand, Lightning components are supported as overrides in Lightning Experience and mobile, but not in Salesforce Classic. Therefore, the developer needs to use different technologies for different user interfaces. The developer can specify the override type and the page or component to use for each user interface in the Buttons, Links, and Actions settings of the Contact object. References: Override Standard Buttons and Tab Home Pages, Standard Actions and Overrides Basics, Override Buttons, Links, and Tabs with Visualforce
