NEW QUESTION # 101
The Account object in an organization has a master-detail relationship to a child object called Branch. The following automations exist:
* Roll-up summary fields
* Custom validation rules
* Duplicate rules
developer created a trigger on the Account object.
Which two things should the developer consider while testing the trigger code?
Choose 2 answers
- A. Rollup summary fields can cause the parent record to go through Save.
- B. The validation rules will cause the trigger to fire again.
- C. Duplicate rules are executed once all DML operations commit to the database.
- D. The trigger may fire multiple times during a transaction.
Answer: A,D
Explanation:
A . Roll-up summary fields can cause the parent record to go through Save:
When a roll-up summary field on a parent object (like Account) is updated due to changes in child records (like Branch), the parent record (Account) is implicitly saved again.
This can result in the execution of the trigger on the parent object. Developers must consider this behavior to avoid unintended recursion or infinite loops.
Reference:
C . The trigger may fire multiple times during a transaction:
Triggers can execute multiple times within a single transaction, especially when there are operations such as updates to the parent record caused by roll-up summary fields or workflows.
Developers should implement logic to ensure that the trigger handles multiple executions correctly (e.g., using a static variable to prevent recursion).
Why not the other options?
B . Duplicate rules are executed once all DML operations commit to the database:
This is incorrect because duplicate rules execute before the DML operation is committed. Duplicate rules prevent duplicate records from being created or updated before the database operation occurs.
D . The validation rules will cause the trigger to fire again:
This is incorrect because validation rules do not cause triggers to fire again. Validation rules validate the record and may prevent DML operations, but they do not independently re-trigger the Apex trigger.

What are three capabilities of the <ltng:require> tag when loading JavaScript resources in Aura components?
Choose 3 answers
- A. One-time loading for duplicate scripts
- B. Specifying loading order
- C. Loading scripts in parallel
- D. Loading externally hosted scripts
- E. Loading files from Documents
Answer: A,B,D
Explanation:
Option A: Specifying loading order
True.
The <ltng:require> tag allows you to specify the order in which scripts are loaded by the sequence in the scripts attribute.
Scripts loaded using <ltng:require> are loaded only once, even if multiple components request the same script, preventing redundant loads.
You can load scripts from external URLs, such as Content Delivery Networks (CDNs), using the scripts attribute.
<ltng:require> cannot load files from the Documents object. It loads resources from static resources or external URLs.
Scripts are loaded sequentially, not in parallel, to ensure dependencies are properly resolved.
Reference:
Include External JavaScript and CSS Libraries
Option B: One-time loading for duplicate scripts
True.
Loading JavaScript Libraries
Option D: Loading externally hosted scripts
True.
Using External Libraries
Option C: Loading files from Documents
False.
Static Resources
Option E: Loading scripts in parallel
False.
Scripts Loading Order
Conclusion:
The three capabilities are A, B, and D.
