NEW QUESTION # 66
A credit card company needs to implement the functionality for a service agent to process damaged or stolen credit cards. When the customers call in, the service agent must gather many pieces of information. A developer is tasked to implement this functionality.
What should the developer use to satisfy this requirement in the most efficient manner?
- A. Screen-based flow
- B. Apex trigger
- C. Lightning Component
- D. Approval process
Answer: A
Explanation:
A screen-based flow is a type of flow that allows you to create a guided, visual experience for users to collect and update data, execute logic, call Apex classes, and more. Screen-based flows are ideal for creating interactive processes that require user input and feedback, such as the scenario of processing damaged or stolen credit cards. A screen-based flow can be embedded in a Lightning page, a Visualforce page, a utility bar, or a custom tab, and can be launched from various places, such as a button, a link, a Lightning component, or a process. A screen-based flow can also leverage standard and custom objects, variables, formulas, and other elements to create dynamic and complex business logic.

NEW QUESTION # 67
The sales management team at Universal Container requires that the Lead Source field of the Lead record be populated when a.. converted.
What should be done to ensure that a user populates the Lead Source field prior to converting a Lead?
- A. Use a formula field.
- B. Create an after trigger on Lead.
- C. Use Lead Conversation field mapping.
- D. Use a validation rule.
Answer: D
Explanation:
The Lead Source field is a standard picklist field that indicates the source of the lead, such as web, phone inquiry, partner referral, and others1. The Lead Source field is related to the contact, account, and opportunity Source fields, and the value can be inherited from one field to the next as a lead progresses through the funnel2. To ensure that a user populates the Lead Source field prior to converting a lead, the best option is to use a validation rule. A validation rule is a formula that evaluates the data in one or more fields and returns a value of true or false3. Validation rules verify that the data a user enters in a record meets the standards you specify before the user can save the record3. By creating a validation rule on the Lead object that checks if the Lead Source field is blank, you can prevent the user from converting the lead without filling in the Lead Source field. You can also display a custom error message to inform the user of the requirement3. For example, the validation rule formula could be:
ISBLANK(LeadSource)
And the error message could be:
Please enter a value for Lead Source before converting the lead.
Using a formula field, Lead Conversion field mapping, or an after trigger on Lead are not effective ways to ensure that the user populates the Lead Source field prior to converting a lead. A formula field is a read-only field that derives its value from a formula expression you define. It cannot be edited by the user and cannot enforce data entry. Lead Conversion field mapping is a way to specify how fields in the lead record are transferred to the fields in the contact, account, and opportunity records during lead conversion. It cannot prevent the user from converting the lead without entering the Lead Source field. An after trigger on Lead is a piece of Apex code that executes after a lead record is inserted, updated, deleted, or undeleted. It cannot validate the data entered by the user before the lead conversion occurs.

NEW QUESTION # 76
How can a developer check the test coverage of active Process Builder and Flows deploying them in a Changing Set?
- A. Use the Flow properties page.
- B. Use the code Coverage Setup page
- C. Use the Apex testresult class
- D. Use SOQL and the Tooling API
Answer: D
Explanation:
To check the test coverage of active Process Builder and Flows deploying them in a Change Set, a developer can use SOQL and the Tooling API. The Tooling API provides the FlowTestCoverage object, which represents the test coverage for a flow or process by a given Apex method. The developer can use SOQL queries to retrieve the FlowTestCoverage records for the flows and processes that are included in the Change Set, and calculate the overall test coverage percentage. The developer can also use the Tooling API to create, update, or delete FlowTestCoverage records.
Option A is incorrect because the Flow properties page does not show the test coverage of the flow or process.
Option B is incorrect because the code Coverage Setup page only shows the test coverage of Apex classes and triggers, not flows or processes. Option C is incorrect because the Apex testresult class only provides information about the test execution results, not the test coverage of flows or processes.
