Question No. 1

visibility of all the installations associated with their opportunities.

What kind of relationship should this new object have to the Opportunity?

Show Answer Hide Answer
Correct Answer: A

The new object should have a lookup relationship to the Opportunity object. A lookup relationship creates a link between two objects and allows related records to be viewed in a related list. This can be used to track installation information for each opportunity and give sales reps visibility of all the installations associated with their opportunities. Option B, C, and D are not appropriate for this requirement.


Question No. 2

An app builder has created a change set and deployed a report from their development sandbox for User Acceptance Testing. When the app builder runs the report, no data is returned.

What can be a reason for this?

Show Answer Hide Answer
Correct Answer: D

Data is unable to be deployed with change sets. Change sets are used to deploy metadata components such as custom objects, fields, workflows, reports, etc. from one Salesforce org to another. However, change sets do not include any data or records from the source org. Users will need to use other tools such as Data Loader or Data Import Wizard to migrate data between orgs. [Source]

To increase adoption, Universal Containers is proposing changes to its Salesforce data model to allow easier visibility for sales reps into key metrics.

Each of these objects has 15 fields they would like to summarize on the Account object.

Correct Answer: A, D

Roll-up summaries allow MAX, MIN, SUM, COUNT, and AVG functions on numeric fields from child records related by a master-detail relationship. Roll-up summaries are limited to master-detail relationships and cannot be used with lookup relationships. An object can have up to 40 roll-up summary fields, not 25. An object can have up to 25 relationship fields (master-detail or lookup), not 20.


Question No. 5

Universal containers wants to ensure that they are accepting clean data from their users and verify that important fields are entered. What should an app builder recommend to meet this requirement?

Show Answer Hide Answer
Correct Answer: D

Configuring a validation rule to require a field for a specific record type is the best way to ensure that important fields are entered and formatted correctly. Updating the important fields to be required on the page layout will not prevent users from entering invalid data using other methods, such as data loader or quick actions. Making a formula field to check the format of the important fields will not prevent users from entering invalid data, but only display a message or an indicator. Creating a workflow rule to check the fields are formatted correctly will not prevent users from entering invalid data, but only trigger an action after the data is saved.
