NEW QUESTION # 100
Salesforce users consistently receive a "Maximum trigger depth exceeded" error when saving an Account.
How can a developer fix this error?
Answer: C
Explanation:
A common solution to the "Maximum trigger depth exceeded" error is to use a static variable in a helper class.
The variable acts as a switch to ensure the trigger logic only executes once per transaction, preventing recursive trigger calls.References: Salesforce Developer Blog - Avoiding Recursive Trigger Calls

NEW QUESTION # 103
A Salesforce org has more than 50,000 contacts. A new business process requires a calculation that aggregates data from all of these contact records. This calculation needs to run once a day after business hours.
which two steps should a developer take to accomplish this?
Choose 2 answers
Answer: C,D
Explanation:
When dealing with large datasets and the need to perform complex calculations or data aggregation, batch Apex and scheduling are typically used to efficiently process records in batches and to execute the process during off-peak hours.
Option B is correct because using the @future annotation allows you to run methods in the background, but it is not suitable for operations that need to process more than 50,000 records, which is the governor limit for future methods.
Option C is correct because implementing the Schedulable interface allows you to schedule the class to run at specified times, such as after business hours, which is a requirement for this scenario.
Option A is incorrect because Queueable is typically used for chaining jobs and handling asynchronous processing of individual transactions, not for processing large datasets at scheduled times.
Option D is incorrect because the Database.Batchable interface is what's needed for processing large datasets, not Database.Stateful. The Database.Stateful interface is used to maintain state across batch job transactions.

NEW QUESTION # 104
A developer has a test class that creates test data before making a mock callout but now receives a 'You have uncommitted work pending. Please commit or rollback before calling out' error.
Which step should be taken to resolve the error?
Answer: C
Explanation:
When working with Apex tests that involve callouts, it's important to avoid the 'uncommitted work pending' error. This error typically occurs because DML operations (like inserts) are pending when a callout is attempted. Salesforce requires that all callouts are made before any DML operations in a transaction. To avoid this, the pattern is to insert the records before calling Test.startTest(), and then make the callout after this call.
Test.startTest() marks the point where your actual test begins, and it resets the governor limits. By making the callout after this point, it ensures that the DML operations are committed and you are within a new execution context regarding governor limits.
