SF-PD2 Testing, Debugging, and Deployment Practice Question
A developer is writing an Apex class that needs to handle high volumes of data. Which pattern should they follow to avoid hitting Governor Limits?
⚠ Common exam trap
Candidates sometimes try to solve governor limits by adding try-catch blocks or reducing batch sizes manually instead of restructuring the loops.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Refactor all SOQL queries and DML statements outside of loops.
Bulkification is the cornerstone of Salesforce development. By processing records in collections (Lists, Maps, Sets) rather than iterating and performing DML or SOQL inside loops, developers keep their code within platform limits. This ensures the code can handle the maximum number of records in a single transaction, which is crucial for scalability and performance in high-volume enterprise applications.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use @future methods for every DML operation.
Why it's wrong here
Overusing @future methods can lead to 'too many future calls' errors if not managed carefully. It also complicates error handling and testing. Future methods should only be used for truly asynchronous tasks, not as a general workaround for avoiding bulkification in a synchronous transaction path.
- ✓
Refactor all SOQL queries and DML statements outside of loops.
Why this is correct
This is the definition of bulkification. By collecting all IDs to query or all records to update into a collection before the loop, the developer reduces the number of calls to the database to a single query/update. This pattern is the single most important factor in avoiding governor limit exceptions.
- ✗
Enable 'Parallel Apex Testing' in the org setup.
Why it's wrong here
Parallel Apex Testing is a feature used to speed up the execution of test suites by running them concurrently. It has nothing to do with the bulkification of the code itself. Enabling this feature will not prevent the code from hitting governor limits during actual runtime in production or sandbox.
- ✗
Increase the record limit by using the Apex 'Limits' class.
Why it's wrong here
The 'Limits' class is used to check current consumption, not to increase the limits. Governor limits are fixed by Salesforce to protect the multi-tenant environment. A developer cannot change these limits; they must write efficient, bulkified code that operates within the constraints provided by the platform.
