What should they use to create the object, fields, and relationships quickly from one place?

Show Answer Hide Answer
Correct Answer: A

Go to Setup Schema Builder.

Drag the 'Object' element into the schema area to create a new custom object.

Define the object's properties (e.g., label, API name).

Drag field elements like Text, Number, or Lookup into the object to create fields.

Configure each field's properties according to your requirements.

Connect objects via lookup or master-detail relationships by dragging the relationship fields between them.

Save the layout to create all elements in Salesforce.

For more information, review Salesforce's Schema Builder documentation.


Question No. 2

Universal Containers (UC) tracks Account locations in Zip Code, a custom text field with a validation rule to enforce proper formatting of the US ZIP+4 code for UC's orders.

What formula should the app builder create on Order to display only the first five digits of Zip Code from the parent Account?

Show Answer Hide Answer
Correct Answer: C

LEFT(Account.Zip_Code_c, 5) is the correct formula to display only the first five digits of Zip Code from the parent Account. LEFT function returns the specified number of characters from the left side of a text string. Account.Zip_Code_c is the custom text field that stores the Zip Code on Account object. 5 is the number of characters to return from the left side of the Zip Code. The other options are not valid formulas or functions.


Question No. 3

Universal Containers uses a private sharing model for opportunities. This model CANNOT be changed due to a regional structure A new sales operations team has been created. This team needs to perform analysis on Opportunity data, all should have read arid write access to all Opportunities.

What are two recommended solutions for the app builder to give the users appropriate access? Choose 2 answers

Show Answer Hide Answer
Correct Answer: A, C

The two recommended solutions for the app builder to give the users appropriate access are creating a criteria based sharing rule to all opportunities with the sales operations public group and adding a permission set with 'View All' and 'Modify All'' opportunity permissions enabled. A criteria based sharing rule can grant read and write access to all opportunities that meet certain criteria to a specified group of users. A permission set can grant additional object-level permissions to users without changing their profiles. Option B is incorrect because adding a manual share for all opportunities with each user on the sales operations team is not scalable or maintainable. Option D is incorrect because creating a criteria-based sharing rule to share all opportunities with the sales operations private group is redundant, as private groups are used to manually share records with individual users or other groups.


Question No. 4

If an employee attempts to edit the description field after submitting an opportunity for approval, they will be presented with a 'Record Lock' notification.
