Workflow: This is another type of automation tool that can execute actions based on certain criteria. In this case, the workflow can have a criteria that evaluates if an opportunity goes to the closed won stage, and then execute an action that posts a message to a Chatter group. Option A and C are not tools that can automate this process.


Question No. 2

A production org includes custom objects containing confidential Information. A sandbox h needed that Includes data records, excludes all of the confidential objects, and can be refreshed weekly the confidential objects, and can be refreshed weekly.

What steps should an App Builder take to meet these requirements?

Show Answer Hide Answer
Correct Answer: C

The steps that the app builder should take to meet these requirements are creating a Partial Copy Sandbox and using a sandbox template. A Partial Copy Sandbox can include data records, exclude confidential objects, and be refreshed weekly. A sandbox template can specify which objects and data are copied from the production org to the sandbox org. Option A is incorrect because creating a Full Sandbox and using a sandbox template is not necessary for this requirement, as Full Sandboxes copy all data and metadata from the production org and can only be refreshed every 29 days. Option B is incorrect because creating a Developer Pro Sandbox and scheduling Data Loader to download selected object data weekly is not feasible for this requirement, as Developer Pro Sandboxes do not include data records by default and Data Loader cannot be scheduled to run weekly. Option D is incorrect because creating a Developer Sandbox and scheduling Data Loader to download selected object data weekly is not feasible for this requirement, as Developer Sandboxes do not include data records by default and Data Loader cannot be scheduled to run weekly.


Question No. 3

The Universal Containers data manager has been complaining about the

lack of data integrity on Contact records.

Sales reps have not been filling out the Region field. The data manager wants the

Region field filled out only for Contacts that are associated to Accounts that have been

marked as 'High Priority' on the Customer Status field.

What can the app builder do to fulfill this requirement?

Show Answer Hide Answer
Correct Answer: B

To ensure data integrity where the Region field on the Contact object needs to be filled out conditionally based on the parent Account's status, a validation rule on the Contact is the most effective method:

B . Create a validation rule on Contact. This rule can enforce that the Region field must be filled out for Contacts related to Accounts marked as 'High Priority'.

Steps to create this validation rule:

Navigate to Setup Object Manager Contact Validation Rules.

Create a new validation rule.

In the formula, use:

AND(

ISPICKVAL(Account.Customer_Status__c, 'High Priority'),

ISBLANK(Region__c)

) )

Provide an error message to display when the rule is violated.

Save and activate the rule.

This validation rule checks that if a Contact is associated with an Account marked 'High Priority', the Region field cannot be blank.

For further detail, Salesforce's Validation Rule Considerations provides additional guidance.
