✓
Executing nested loops over large collections of sObjects.
Heavy loops, complex triggers, inefficient nested queries or collections processing, and excessive regex or string manipulations contribute to CPU time exhaustion.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Executing nested loops over large collections of sObjects.
Why this is correct
Nested loops with high iteration counts rapidly consume CPU time.
- ✓
Running complex string manipulations or regular expression matching on large text bodies.
Why this is correct
Heavy string and regex processing are computationally expensive and consume CPU time.
- ✗
Invoking too many SOQL queries within the 100 query limit.
Why it's wrong here
While queries take time, the specific count limit is 100; CPU time is measured in milliseconds of processing.
- ✗
Exceeding the total number of allowed DML statements.
Why it's wrong here
Exceeding DML statement limits throws a DML limit exception, not a CPU time exception.
- ✓
Executing heavy calculations inside triggers processing large bulk record batches.
Why this is correct
Processing large batches with complex logic in triggers exceeds CPU limits.
