Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Invoking a future method directly from a scheduled Apex class execute method.
Why it's wrong here
Calling future methods from scheduled Apex is permitted.
- ✓
Exceeding the maximum synchronous heap size of 6 MB by loading massive attachments into collections.
Why this is correct
Large data collections exceed the 6 MB synchronous heap limit.
- ✓
Performing individual DML statements inside a loop for each record in Trigger.new.
Why this is correct
DML inside loops hits the 150 DML statement limit.
- ✗
Accessing Trigger.old in an insert trigger.
Why it's wrong here
Accessing Trigger.old in an insert trigger returns null, but does not throw a governor limit exception.
- ✓
Executing a SOQL query inside a for loop that iterates over Trigger.new.
Why this is correct
Querying inside loops easily exceeds the 100 SOQL query limit.
