Salesforce Updated Platform-App-Builder Exam Questions and Answers by ovie

 Apex. This is correct because Apex is a programming language that can perform complex logic and manipulate data in Salesforce. Apex can be used to create a trigger on the opportunity object that copies the value of the billing state from the related account record when the opportunity is created, and prevents it from being changed afterwards. The other options are not suitable for this requirement because they either cannot copy data from a related object (formula field, roll-up summary field) or cannot prevent data from being changed (workflow).

The app builder should use Web-to-Case to enable visitors to the website to open cases. Web-to-Case is a feature that allows users to create an HTML form that can be embedded into a public-facing website. When visitors fill out and submit the form, a new case is automatically created in Salesforce with the information from the form fields. Web-to-Case can also assign cases to queues or users based on predefined rules and criteria. Outbound message is not a valid tool, as it does not enable visitors to open cases. An outbound message is a type of workflow action that sends a secure XML message to a designated endpoint URL when a record meets certain criteria. An outbound message can be used to integrate Salesforce with external systems or applications. Screen flow is not a valid tool, as it does not enable visitors to open cases from a public-facing website. A screen flow is a type of flow that allows users to create an interactive guided process that can collect, display, and update data from multiple objects within Salesforce. A screen flow can be embedded into Lightning pages or Visualforce pages, but it cannot be exposed to unauthenticated users on a public website. Email-to-Case is not a valid tool, as it does not enable visitors to open cases from a website. Email-to-Case is a feature that allows users to create cases from email messages sent to a specific email address. Email-to-Case can also capture email attachments and thread information and associate them with the case.

 The app builder wants to create a formula field on an Account to include data from related Contacts but cannot find the relationship in the formula editor. This limitation occurs because formula fields in Salesforce cannot reference child records directly.

Option A (Unable to reference the child records): In Salesforce, formula fields can reference parent objects but not child objects. In this case, Contacts are child records of Accounts in a lookup relationship, and Account is the parent. This is why the formula editor does not provide access to the child records (Contacts) from the Account.

To meet the requirement of summarizing the number of open and closed cases on an Account, two potential automation solutions can be used:

Option A (AppExchange): Salesforce AppExchange offers various pre-built apps and components, including those for case management, which could provide the functionality to summarize cases and categorize customer support utilization. Many apps can handle complex business requirements like case summary roll-ups and could meet the needs without custom development.
