Salesforce Updated PDI Exam Questions and Answers by bernie

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.

Marking the field as Required on the field definition ensures that the field cannot be left blank or null when a record is created or updated, regardless of the page layout or the API. This is the most efficient way to enforce a value for the picklist field, as it does not require any additional configuration or code. Setting the first value as the default value does not prevent the user from changing or clearing the value. Setting a validation rule requires writing a formula and handling error messages. Marking the field as Required on the page layout only affects the user interface, not the API or other tools. References:

The @TestSetup annotation method is used to create records for every method in the test class. This method is executed before any test method in the class and the records created in this method are available to all test methods in the class. The records are rolled back at the end of the test class execution. If a test method modifies or deletes the records created in the test setup method, those changes are rolled back after each test method finishes execution. The next executing test method gets access to the original unmodified state of those records. This annotation method can reduce test execution times and improve system resource efficiency compared to creating records for each test method individually. References: Using Test Setup Methods, Free Salesforce Platform Developer 1 Practice Exam (With Answers), SALESFORCE CERTIFIED PLATFORM DEVELOPER I

Lightning Data Service is the preferred (and easiest) way to work with Salesforce data. With Lightning Data Service, developers use JavaScript to connect components to Salesforce data1. Lightning Data Service also provides security by making server calls to secure User Interface API endpoints2. Lightning Data Service respects the sharing rules and field-level security of the current user, so developers do not need to write any additional code to enforce them3. The other options are either incorrect or irrelevant for Lightning Data Service. References:
