Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Using maps and collections to store query results and perform in-memory lookups instead of querying inside loops.
Why this is correct
In-memory map lookups eliminate repetitive SOQL queries inside loops.
- ✓
Writing queries that retrieve only the specific fields and records required using WHERE clauses.
Why this is correct
Selective queries reduce data transfer and processing overhead.
- ✓
Using relationship queries (parent-to-child or child-to-parent) to retrieve related data in a single query.
Why this is correct
Relationship queries retrieve related parent and child records efficiently in one query.
- ✗
Executing SOQL queries inside a for loop iterating over all child records.
Why it's wrong here
Queries inside loops are the primary cause of SOQL query limit violations.
- ✗
Calling Database.query() for every single record processed in a trigger.
Why it's wrong here
Dynamic queries per record will quickly exceed the 100 SOQL query limit.
