NEW QUESTION # 31
While working in a sandbox, an Apex test fails when run in the Test Runner. However, executing the Apex logic in the Execute Anonymous window succeeds with no exceptions or errors. Why did the method fail in the sandbox test framework but succeed in the Developer Console?
- A. The test method relies on existing data in the sandbox.
- B. The test method is calling an @future method.
- C. The test method does not use Sysetem.runas= to execute as a specific user.
- D. The test method has a syntax error in the code.
Answer: A
Explanation:
The Apex test fails in the Test Runner but succeeds in the Execute Anonymous window because the test method relies on existing data in the sandbox.
Isolation of Test Data: By default, Apex tests do not have access to pre-existing data in the organization. Tests are executed in an isolated context to ensure they are not dependent on external data, promoting reliability and repeatability.
"Apex test methods don't have access to pre-existing data in the organization. The test methods have access to all data that they create and to changes made by other test methods (unless the @IsTest(Isolated=true) annotation is used)."
- Apex Developer Guide: Isolation of Test Data from Organization Data in Unit Tests Execute Anonymous Window: When code is run in the Execute Anonymous window, it executes in the current user's context and has access to all organization data, including existing records.
"All Apex code runs in system mode. The only exception is anonymous blocks, such as code executed using the Execute Anonymous window or the SOAP API."
- Apex Developer Guide: Enforcing Object and Field Permissions
Solution: To fix the failing test, the developer should create the necessary test data within the test method or use the @IsTest(SeeAllData=true) annotation if access to existing data is absolutely necessary (though this is generally discouraged).
"If you specify @IsTest(SeeAllData=true), the test method has access to all data in the organization, but the test can be slower and less reliable because it might depend on data that changes."
- Apex Developer Guide: Using the SeeAllData Annotation
Why Other Options Are Incorrect:
Option A: While calling an @future method requires special handling in tests, it would not cause the method to pass in Execute Anonymous and fail in tests.
Option C: A syntax error would prevent the code from compiling, so it wouldn't run in either context.
Option D: Using System.runAs is only necessary when testing code that behaves differently for users with different profiles or permissions.
Conclusion: The discrepancy arises because the test method is attempting to access data that isn't available in the test context, leading to its failure in the Test Runner but success in the Execute Anonymous window.
NEW QUESTION # 32
Which exception type cannot be caught?
- A.
- B.
- C.
- D.
Answer: D
Explanation:
The exception type that cannot be caught is the LimitException. This exception is thrown when some governor limit is exceeded (like SOQL query limits, number of records that can be processed in a transaction, etc.).
Salesforce doesn't allow developers to catch LimitException in order to maintain the multi-tenant environment and ensure that no single tenant consumes excessive resources.

NEW QUESTION # 36
Which Apex class contains methods to return the amount of resources that have been used for a particular governor, such as the number of DML statements?
- A. OrgLimits
- B. Exception
- C. Messaging
- D. Limits
Answer: D
Explanation:
TheLimitsclass in Apex provides methods to check the consumption of governor limits, such as the number of SOQL queries, DML statements, and heap size used.
Example:
Integer dmlStatements = Limits.getDMLStatements();
Integer dmlLimit = Limits.getLimitDMLStatements();
Not Suitable:
Option A:OrgLimitsis not an Apex class.
Option C:Messagingdeals with email and messaging operations.
Option D:Exceptionis for handling exceptions, not tracking resource usage.
Limits Class
Reference:Apex Developer Guide - Limits Class
This concept falls under"Testing, Debugging, and Deployment"(22% weight) in the PD1 guide, as developers need to monitor and test for governor limits to ensure Apex code scalability and reliability.

NEW QUESTION # 44
Einstein Next Best Action Is configured at Universal Containers to display recommendations to internal users on the Account detail page.
If the recommendation is approved, a new opportunity record and task should be generated. If the recommendation is rejected, an Apex method must be executed to perform a callout to an external system.
Which three factors should a developer keep Hi mind when implementing the Apex method?
Choose 3 answers
- A. The method must be defined as public.
- B. The method must be defined as static.
- C. The method must use the @Future annotation.
- D. The method must use the @AuraEnabled annotation.
- E. The method must use the @invocableMethod annotation.
Answer: B,C,E
Explanation:
To implement the Apex method that is executed when a recommendation is rejected, the developer should keep in mind the following factors:
* The method must use the @Future annotation because it performs a callout to an external system, which is not allowed in synchronous Apex. The @Future annotation marks a method as asynchronous, meaning that it runs in a separate thread and does not block the main execution1.
* The method must use the @invocableMethod annotation because it is invoked from a flow that is triggered by the Einstein Next Best Action component. The @invocableMethod annotation enables an Apex method to be called from a flow, process, or REST API2.
* The method must be defined as static because it is annotated with @Future and
@invocableMethod. Both annotations require the method to be static, meaning that it belongs to the class and not to any instance of the class3.

NEW QUESTION # 50
The values 'High', 'Medium', and 'Low' are Identified as common values for multiple picklist across different object. What is an approach a developer can take to streamline maintenance of the picklist and their values, while also restricting the values to the ones mentioned above?
- A. Create the Picklist on each object and select "Restrict picklist to the values defined in the value set".
- B. Create the Picklist on each object as a required field and select "Display values alphabeticaly, not in the order entered".
- C. Create the Picklist on each object and use a Global Picklist Value Set containing the Values.
- D. Create the Picklist on each and add a validation rule to ensure data integrity.
Answer: C
Explanation:
A global picklist value set is a collection of values that can be shared across multiple picklist fields on different objects1. By using a global picklist value set, a developer can streamline the maintenance of the picklist and their values, as they only need to define the values once and reuse them across multiple fields. The global picklist value set also restricts the values to the ones defined in the value set, so that users cannot enter or select other values1.
Option B is incorrect, because creating the picklist on each object as a required field and selecting
"Display values alphabetically, not in the order entered" does not streamline the maintenance of the picklist and their values, nor does it restrict the values to the ones mentioned above. The developer would still need to create and maintain the picklist values for each object separately, and the users could still enter or select other values that are not 'High', 'Medium', or 'Low'.
Option C is incorrect, because creating the picklist on each object and selecting "Restrict picklist to the values defined in the value set" does not streamline the maintenance of the picklist and their values, either. The developer would still need to create and maintain the picklist values for each object separately, even if they use the same value set. The only benefit of this option is that it restricts the values to the ones defined in the value set.
Option D is incorrect, because creating the picklist on each object and adding a validation rule to ensure data integrity is not the best approach to streamline the maintenance of the picklist and their values, while also restricting the values to the ones mentioned above. The developer would need to write and maintain the validation rule for each object, which is more complex and error-prone than using a global picklist value set. The validation rule would also run after the user enters or selects a value, which is less user-friendly than preventing the user from entering or selecting an invalid value in the first place.
