Choose 2 answers

Unify all three triggers in a single trigger on the expense__c object that includes all events.

Create helper classes to execute the appropriate logic when a record is saved.

Maintain all three triggers on the expense__c object, but move the Apex logic out of the trigger definition.

Unify the before insert and before update triggers and use Flow for the delete action.

Question # 20

Universal Containers wants Opportunities to no longer be editable when it reaches the Closed/Won stage.

Which two strategies can a developer use to accomplish this?

Use a validation rule.

Use a before-save Apex trigger.

Use an automatically launched Approval Process.

Use an auto-response rule.

Full Access

Answer:

Explanation:

Universal Containers wants to prevent Opportunities from being edited once they reach the Closed/Won stage. To achieve this, the developer can use the following strategies:

Option A: Use a validation rule.

Correct Approach.

Explanation:

A validation rule can be created on the Opportunity object to prevent users from editing records when the Stage is Closed/Won.

The validation rule would evaluate whether the record's StageName is 'Closed Won' and, if so, display an error message when a user attempts to edit and save the record.

Example Validation Rule:

AND(

ISPICKVAL(StageName, 'Closed Won'),

ISCHANGED(ANYFIELD) // Replace ANYFIELD with specific fields if needed

)

Benefits:

Declarative Solution: No code required.

Consistent Enforcement: Applies across all user interfaces and API.

[Reference:, Validation Rules, Validation Rule Examples, Option B: Use a before-save Apex trigger., Correct Approach., Explanation:, An Apex trigger can be written to check if an Opportunity record being modified has a StageName of 'Closed Won'., In a before update trigger, the trigger can prevent the save operation by adding an error to the record., Sample Apex Trigger:, trigger PreventOpportunityEdit on Opportunity (before update) {, for (Opportunity opp : Trigger.new) {, Opportunity oldOpp = Trigger.oldMap.get(opp.Id);, if (oldOpp.StageName == 'Closed Won' && opp != oldOpp) {, opp.addError('Closed Won Opportunities cannot be edited.');, }, }, }, , Benefits:, Programmatic Control: Allows for complex logic., Granular Enforcement: Can specify exact conditions under which edits are prevented., Reference:, Apex Triggers, Trigger Context Variables, Options Not Suitable:, Option C: Use an automatically launched Approval Process., Incorrect., Explanation:, Approval Processes are designed for record approval workflows., They do not inherently prevent edits based on a field value like StageName., Option D: Use an auto-response rule., Incorrect., Explanation:, Auto-response rules are used to send automated email responses to Leads or Cases., They do not control record editability., Conclusion:, The most appropriate strategies are A (Validation Rule) and B (Before-save Apex Trigger)., Both methods effectively prevent users from editing Opportunities in the Closed/Won stage., , ]

Question # 22

Universal Containers (UC) uses out-of-the-box order management, that has a Master-Detail relationship between Order and Order Line Item.

UC stores the availability date on each Order Line Item and Orders are only shipped when all of the Order Line Items are available.

Which method should be used to calculate the estimated ship date for an Order?

Use a MAX Roll-Up Summary field on the latest availability date fields.

Use a CEILING formula on each of the latest availability date fields.

Use a LATEST formula on each of the latest availability date fields.

Use a DAYS formula on each of the availability date fields and a COUNT Roll-Up Summary field on the Order.

Full Access

Answer:

Explanation:

Universal Containers (UC) wants to calculate the estimated ship date for an Order, which should be the date when all Order Line Items are available. The availability date is stored on each Order Line Item.

Given that the relationship between Order and Order Line Item is Master-Detail, we can leverage Roll-Up Summary Fields to perform calculations on the child records (Order Line Items) and summarize them on the parent record (Order).

Option A: Use a MAX Roll-Up Summary field on the latest availability date fields.

Correct Approach.

Explanation:

Create a Roll-Up Summary Field on the Order object.

Use the MAX function to calculate the latest availability date among all related Order Line Items.

The Roll-Up Summary Field will display the maximum (latest) availability date, which represents the date when all items are available.

This date can be used as the estimated ship date for the Order since the Order can only be shipped when all items are available.

Benefits:

Declarative Solution: No code required.

Real-Time Calculation: Automatically updates when Order Line Items change.

[Reference:, Roll-Up Summary Fields, Defining Roll-Up Summary Fields, Why Other Options are Not Suitable:, Option B: Use a CEILING formula on each of the latest availability date fields., Incorrect Function Usage., Explanation:, The CEILING function returns the smallest integer greater than or equal to a number., It is used with numerical values, not date fields., Does not help in calculating the latest date among multiple dates., Option C: Use a LATEST formula on each of the latest availability date fields., Non-Existent Function., Explanation:, There is no LATEST function available in Salesforce formula fields., Cannot be used to calculate dates., Option D: Use a DAYS formula on each of the availability date fields and a COUNT Roll-Up Summary field on the Order., Does Not Address the Requirement., Explanation:, The DAYS function returns the number of days between two dates., Using COUNT Roll-Up Summary counts the number of child records but does not help in finding the latest date., This approach does not calculate the estimated ship date based on the latest availability date., Conclusion:, Using a MAX Roll-Up Summary Field on the Order object to find the latest availability date among Order Line Items is the appropriate method., This method efficiently calculates the estimated ship date for an Order based on when all items are available., ]
