Answer choices
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
✓
Use trigger context variables like Trigger.new to process records in bulk.
Triggers must be bulkified to handle collections of records and queries/DML operations must be kept outside loops.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Place DML statements inside 'for' loops to ensure immediate database commits.
Why it's wrong here
DML inside loops will trigger DML limits after 150 iterations.
- ✗
Use the 'webservice' keyword on helper methods called by triggers.
Why it's wrong here
The 'webservice' keyword exposes methods as SOAP web services and is not used for trigger optimization.
- ✗
Execute a separate SOQL query for every single record in Trigger.new.
Why it's wrong here
Querying per record violates SOQL query limits and is an anti-pattern.
- ✓
Use trigger context variables like Trigger.new to process records in bulk.
Why this is correct
Trigger context variables hold collections of sObjects, allowing batch processing of records.
- ✓
Perform SOQL queries and DML operations outside of loops.
Why this is correct
Querying and performing DML inside loops quickly leads to governor limit exceptions.
