For detailed setup instructions, see Salesforce's documentation on Creating Quick Actions.


Question #3

Northern Trail Outfitters wants to change a master-detail relationship on

Account to a lookup relationship with a custom object Park. The app builder tries to

reconfigure this but is unable to do so.

What could be causing this?

Reveal Solution Hide Solution
Correct Answer: C

When attempting to change a master-detail relationship to a lookup relationship, Salesforce imposes specific restrictions to maintain data integrity:

C . The Account record includes Parks roll-up summary fields. Master-detail relationships allow roll-up summary fields to aggregate data from child records onto the parent record. If any roll-up summary fields are present on the master object (Account in this case) that depend on the detail records (Parks), the relationship cannot be changed to lookup until these roll-up summary fields are removed.

To resolve this, follow these steps:

Identify and delete all roll-up summary fields on the Account object that reference the Park object.

Convert the master-detail relationship to a lookup relationship.

Recreate any necessary roll-ups using declarative tools like Process Builder or Flow if needed, as lookups do not support native roll-up summaries.

For more guidance, review Salesforce's documentation on Changing Field Types.

Question #5

Cloud Kicks wants to summarize the number of open Cases related to an Account, as well as the number of closed Cases to indicate whether customer support utilization is high, medium, or low. Two number fields have been created: NUM_Open_Cases__c and NUM_Closed_Cases_c

Which two automation solutions would meet these business requirements?

Choose 2 answers

Reveal Solution Hide Solution
Correct Answer: B, D

Process Builder and Apex are two automation solutions that can meet the business requirements of summarizing the number of open and closed Cases related to an Account. Process Builder can create a process that updates the custom fields on Account based on changes in related Cases. Apex can write a trigger that performs the same logic using code. AppExchange and Workflow are not automation solutions for this requirement, but sources of apps or components and tools for creating workflow rules respectively.
