Question 1

Universal Containers utilizes a strict multi-tenant environment. A developer is designing a complex Apex process that processes thousands of Opportunity records nightly. To ensure the logic does not monopolize shared resources and violate governor limits, which architectural pattern should be prioritized?

Accepted Answer

Utilize the Batchable interface to process records in smaller chunks, resetting governor limits for each transaction.

Answer

Implement the logic within a standard trigger using synchronous execution to ensure immediate completion.

Answer

Use a @future method to process all records in a single asynchronous transaction.

Answer

Bypass governor limits by using the "Without Sharing" keyword in the class definition.

Question 2

A developer needs to store a Many-to-Many relationship between `Candidate__c` and `Position__c`. The requirement dictates that if a Position is deleted, all associated application records linking it to Candidates should also be automatically deleted. However, deleting a Candidate should not delete the Position history. Which data model configuration satisfies this requirement?

Accepted Answer

Create a junction object `Application__c` with two Master-Detail relationships: one to `Position__c` and one to `Candidate__c`.

Answer

Create a junction object `Application__c` with a Lookup relationship to `Position__c` and a Master-Detail relationship to `Candidate__c`.

Answer

Create a junction object `Application__c` with two Lookup relationships and a Process Builder to handle deletion.

Answer

Create a generic parent object and use Indirect Lookup relationships for both `Candidate__c` and `Position__c`.

Question 3

Cloud Kicks is integrating an external ERP system with Salesforce. The ERP system sends nightly upserts of Product records. To prevent duplicate records and ensure efficient updates without querying Salesforce first, which field type should the developer configure on the Product object to act as a unique identifier for the upsert operation?
