NEW QUESTION # 12
An org has a requirement that an Account must always have one and only one Contact listed as Primary. So selecting one Contact will de-select any others. The client wants a checkbox on the Contact called 'Is Primary' to control this feature.
The client also wants to ensure that the last name of every Contact is stored entirely in uppercase characters.
What is the optimal way to implement these requirements?
Answer: A
Explanation:
A single trigger on Contact that handles both after update and before update events, utilizing helper classes for each logic set, is the most optimal implementation. It centralizes the logic for maintaining primary contacts and normalizing last names while allowing for clear separation of concerns through helper classes.
NEW QUESTION # 13
Given the following code:
Assuming there were 10 Contacts and five Accounts created today, what is the expected result?
Answer: D
Explanation:
The loop contains a SOQL query inside, causing it to run multiple times. This will throw a QueryException because the Account query returns more than one row.
NEW QUESTION # 14
A company wants to run different logic based on an Opportunity's record type.
Which code segment handles this request and follows best practices?
A)
B)
C)
D)
Answer: A
Explanation:
The use of getRecordTypeInfosByDeveloperName is a best practice to handle record types. This approach avoids the need for SOQL queries, reducing the number of governor limits consumed, and efficiently retrieves record type Ids by their DeveloperName, which is consistent across all Salesforce environments.
NEW QUESTION # 15
An Apex class does not achieve expected code coverage. The testsetup method explicitly calls a method In the Apex class..
How can the developer generate the code coverage?
Answer: C
Explanation:
When an Apex class does not achieve the expected code coverage, it suggests that the test methods are not executing parts of the class. The @testvisible annotation can be used to increase code coverage by allowing test methods to access private or protected members of another class. This enables the test method to call methods that may not be directly accessible, but it is not a direct means to generate code coverage. The code coverage is actually achieved when the test methods execute the code within these methods. Therefore, to properly generate code coverage, the developer must ensure that the test methods call the relevant portions of the code that need to be covered. The use of @testvisible can facilitate this process by making otherwise inaccessible code available for testing.

NEW QUESTION # 16
Refer to the test method below:
The test method tests an Apex trigger that the developer knows will make a lot of queries when a lot of Accounts are simultaneously updated to be customers. The test method fails at the Line 20 because of too many SOQL queries. What is the correct way to fix this? A)
B)
C)
D)
Answer: B
Explanation:
The correct way to fix this is to add Test.startTest() before and add Test.stopTest() after Line 18 of the code. This will reset the governor limits for the code that executes between these two methods, and allow the test to run without hitting the SOQL query limit.The Test.startTest() and Test.stopTest() methods are used to test code that makes a lot of queries or calls asynchronous methods12. By using these methods, the developer can isolate the code that needs more resources and verify that it does not exceed the governor limits.
