Ursa Major Solar's service department gets requests for several types of services, such as installation, repair, and maintenance. Service managers need to be able to tell when maintenance was last done on on asset to help determine If they are meeting contract agreements, but the last maintenance date can be difficult to determine when there are many work orders related to the asset. They think it would be helpful to have a field auto-populated on the Asset record when a maintenance work order gets closed.
What tool should an app builder recommend to help meet this requirement?

  1. Visualforce
  2. Roll-up Summary
  3. Apex Trigger
  4. Flow

Answer(s): D

Explanation:

A flow is an application that automates a business process by collecting data and performing operations in your org or an external system. Flows can also manipulate data in your org by creating, updating, deleting, or submitting records for approval. You can use flows to update fields on related records when a certain event occurs, such as closing a work order. In this case, a flow can be used to update the last maintenance date field on the Asset record when a maintenance work order gets closed.



At Universal Containers, the Account object has a Master-Detail relationship with an Invoice custom object. The App Builder would like to change to a lookup field, but is not able to do so.
What could be causing this?

  1. The invoice must have at least one Master-Detail field for reporting.
  2. The Account record includes Invoice roll-up summary fields.
  3. The Invoice records have existing values in the Account.
  4. The Account is included in the workflow on the Invoice object.

Answer(s): B

Explanation:

The Account record includes Invoice roll-up summary fields. This is correct because roll-up summary fields are only available on the master object in a master-detail relationship, and changing the field type to lookup would delete the roll-up summary fields



Ursa Major Solar has a lookup relationship between a custom Galaxy _c object and a custom Star_c object. An app builder wants to create a roll-up summary field that counts the total number of Star_c records related to each Galaxy__c record.
How would the current configuration impact the ability to achieve the desired result?

  1. The roll-up summary can be achieved by creating a formula field on the Galaxy__c object.
  2. The lookup relationship will need to be converted to a master-detail relationship before a roll-up summary field can be created.
  3. The roll-up summary can be achieved by creating a formula field on the Star__c object.
  4. A roll-up summary field will need to be created on the Galaxy__c object with a field filter that select all related Star_c records

Answer(s): B

Explanation:

The lookup relationship will need to be converted to a master-detail relationship before a roll-up summary field can be created. This is correct because roll-up summary fields are only available on the master object in a master-detail relationship, and a lookup relationship does not establish a parent-child hierarchy between the objects



Service agents at Ursa Major Solar want a more condensed case view. Service agents also want to be able to modify the associated contact and account records from the case page layout on the

Lightning record page.
Which two components should an app builder use to meet these requirements? Choose 2 answers

  1. Path
  2. Rich text
  3. Related record
  4. Tabs

Answer(s): C,D

Explanation:

Related record and Tabs. These are correct because the related record component allows service agents to view and edit fields from a related record on the same page, and the tabs component allows service agents to switch between different views of related lists or other components on the same page.



A sales rep at AW Computing is unable to find what they are looking for while scrolling through their Chatter feed.
How can a filter be utilized to show only posts from their key account and opportunity records?

  1. Create a Chatter group.
  2. Create Chatter bookmarks
  3. Create a Chatter stream.
  4. Create a Chatter notification.

Answer(s): C

Explanation:

Create a Chatter stream. This is correct because a Chatter stream allows users to follow multiple records and people in one feed, and filter the feed by selecting a stream.
