 Importing data using the Data Loader and the Bulk API causes a before trigger to fire by default for Accounts. A before trigger is a type of trigger that executes before a record is saved to the database. A before trigger can be used to validate or modify the record values before they are inserted or updated1. When using the Data Loader or the Bulk API to import data, the before trigger will run for each batch of records that are processed2.

The other options are not correct because:

• Renaming or replacing picklist values does not cause a before trigger to fire, as it does not affect the record values directly. However, it may affect the validation rules or formulas that reference the picklist values3.
• Converting Leads to Contact accounts does not cause a before trigger to fire, as it is a special operation that bypasses the standard trigger execution order. Instead, the LeadConvert class can be used to override the default lead conversion process and invoke custom logic.
• Updating addresses using the Mass Address update tool does not cause a before trigger to fire, as it is a tool that allows users to update address fields on multiple records at once. However, it may cause an after trigger to fire, as it updates the records in the database.

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.

 A trigger is a piece of Apex code that executes before or after certain events, such as insert, update, delete, or undelete1. An aggregate function is a function that performs a calculation on a set of values and returns a single value, such as SUM, COUNT, AVG, MIN, or MAX2. A roll-up summary field is a field that calculates values from related records, such as those in a related list3. However, roll-up summary fields are only available for master-detail relationships, not for lookup relationships3. Therefore, to achieve a similar functionality for a custom object that is not in a master-detail relationship with the Opportunity object, a trigger can be written on the child object that uses an aggregate function to sum the amount for all related child objects under the Opportunity object. The trigger should handle different scenarios, such as insert, update, delete, or undelete of the child records, and update the corresponding Opportunity record accordingly. References:

 The correct answer is C and D because they are the characteristics of Lightning Web Component custom events as described in the Salesforce documentation1. A custom event is an event that a component fires to communicate data to other components. By default, a custom event only propagates to its immediate container, which is the component that created it or the component that hosts the component that created it. To propagate the event beyond the immediate container, the component that fires the event must set the composed property of the event to true. A custom event can pass data to other components in the payload using a property called detail, which can be any JavaScript object. The other options are incorrect because they are not true for Lightning Web Component custom events. Option A is incorrect because a wire decorated property is a property that is automatically updated with data from a Salesforce org or an Apex method. It is not related to custom events. Option B is incorrect because a custom event does not propagate to its immediate child component by default, unless the child component is the one that fires the event or the event is composed. References:
