Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Omitting LIMIT clauses on large queries to ensure all records are fetched at once.
Why it's wrong here
Omitting limits on unbounded tables can cause heap size and row limit violations.
- ✓
Filtering queries using indexed fields (such as Id, Name, or external IDs) where possible.
Why this is correct
Using indexed fields improves query performance and reduces CPU overhead.
- ✓
Querying records into lists rather than single sObject variables when multiple records match.
Why this is correct
Using list queries prevents QueryException when multiple rows are returned.
- ✓
Using bind variables to pass collection criteria into SOQL WHERE clauses.
Why this is correct
Bind variables optimize query execution and allow bulk filtering.
- ✗
Placing SOQL queries inside helper methods called within loops.
Why it's wrong here
Putting queries inside loops is an anti-pattern that violates query limits.
