Salesforce Certified Platform Developer II - Multiple Choice Sample Questions (Q172-Q177):

NEW QUESTION # 172
A company's support process dictates that any time a case is closed with a status of "Could net fix," an Engineering Review custom object record should be created and populated with information from the case, the contact, and any of the products associated with the case.
What Is the correct way to automate this using an Apex trigger?

A. An after update trigger on Case that creates the Engineering Review record and inserts it
B. An after upset trigger on Case that creates the Engineering Review record and inserts It .
C. A before update trigger on Case that creates the Engineering Review record and Inserts It
D. A before upset trigger on Case that creates the Engineering Review record and Inserts it

Answer: A

Explanation:
In Salesforce, triggers can be defined to execute before or after a DML operation. An "after" trigger is used when you want to use the records that have been changed and rely on their committed values. In this scenario, you would use an after update trigger because you need to create a new record (Engineering Review) after the case has been updated with a status of "Could not fix". This cannot be done in a "before" trigger because the changes have not yet been committed to the database.
Therefore, the correct answer is A, which specifies an after update trigger on the Case object to create and insert the Engineering Review record.

A business currently has a process to manually upload orders from its external Order Management System (OMS) into Salesforce.
This is a labor intensive process since accounts must be exported out of Salesforce to get the IDs. The upload file must be updated with the correct account IDs to relate the orders to the corresponding accounts.
Which two recommendations should make this process more efficient?
Choose 2 answers

A. Use the upsert wizard in the Data Loader to import the data.
B. Ensure the data in the file is sorted by the order ID.
C. Use the insert wizard in the Data Loader to import the data.
D. Identify unique fields on Order and Account and set them as External IDs.

Answer: A,D

The upsert operation in Data Loader can then use these External IDs to relate records, which streamlines the process and avoids the need to export Salesforce IDs manually.
