What should an app builder recommend to meet these requirements?

Show Answer Hide Answer
Correct Answer: D

Create a master-detail relationship field on Applicant__c to Application__c is what the app builder should recommend to meet the requirements of allowing the same applicant to apply for multiple open positions using a single application. This will create a many-to-many relationship between Applicant__c and Open_Position__c using Application__c as a junction object. Create a master-detail relationship on Open_Position__c to Application__c, create a master-detail relationship field on Application__c to Open_Position__c, and create a lookup relationship field on Applicant__c to Application__c are not valid or correct ways to create a many-to-many relationship.


Question No. 2

Cloud Kicks wants to know the total value of all won Opportunities for Accounts and display it on the record.

What type of summary should the app builder use in the roll-up summary field?

Show Answer Hide Answer
Correct Answer: C

The app builder should use Sum as the type of summary in the roll-up summary field. A Sum type of summary allows the app builder to calculate the total value of a numeric field from the child records related to a parent record by a master-detail relationship. The app builder can create a roll-up summary field on the Account object that sums the Amount field from the won Opportunities related to each Account. Count is not a valid type of summary, as it does not calculate the total value of a numeric field. A Count type of summary allows the app builder to count the number of child records related to a parent record by a master-detail relationship. Max is not a valid type of summary, as it does not calculate the total value of a numeric field. A Max type of summary allows the app builder to display the largest value of a numeric or date field from the child records related to a parent record by a master-detail relationship. Min is not a valid type of summary, as it does not calculate the total value of a numeric field. A Min type of summary allows the app builder to display the smallest value of a numeric or date field from the child records related to a parent record by a master-detail relationship.

Which three features would meet the business requirements?

Choose 3 answers

Show Answer Hide Answer
Correct Answer: B, C, E

The app builder should use three features to meet the business requirements:

Process Builder: This is a type of automation tool that can execute actions based on certain criteria. In this case, the process builder can have a criteria that evaluates if an opportunity is in the Secure Commitment Stage, and then execute an action that submits it for approval.

Apex: This is a programming language that allows developers to execute complex logic on the Salesforce platform. Apex can be used to create triggers that run before or after certain events, such as insert, update, delete, or undelete of records. In this case, Apex can be used to create a trigger that runs before an opportunity is updated and submits it for approval if it is in the Secure Commitment Stage.

Flow: This is another type of automation tool that can guide users through a series of screens and perform actions based on user input. Flow can also be triggered by certain events, such as when a record is created or updated. In this case, Flow can be used to create a record-triggered flow that runs after an opportunity is updated and submits it for approval if it is in the Secure Commitment Stage. Option A and D are not features that can meet the business requirements.


Question No. 5

Sales Managers want to be automatically notified any time there is a change to an Opportunity Close Date and want these changes to be tracked on the Opportunity.

Which two configurations should an app builder recommend?

Choose 2 answers

Show Answer Hide Answer
Correct Answer: B, D

Using Process Builder on Opportunities and a Chatter post action, and enabling Feed Tracking on Opportunities are two configurations that an app builder can recommend to meet the requirement of notifying and tracking changes to an Opportunity Close Date. Process Builder can create a process that triggers a Chatter post action when the Close Date field is changed on an Opportunity. Feed Tracking can enable tracking of field history for the Close Date field on the Opportunity feed. Creating an Opportunity outbound message and activating Historical Trending for Opportunities are not valid configurations for this requirement.
