Subscribe the OpportunityHistory Change Data Capture event in the Lightning component.

Subscribe to the Opportunity Change Data Capture event in the Lightning component.

Just prior to a new deployment the Salesforce administrator, who configured a new order fulfillment process feature in a developer sandbox, suddenly left the company. As part of the UAT cycle, the users had fully tested all of the changes in the sandbox and signed off on them; making the Order fulfillment feature ready for its go-live in the production environment. Unfortunately although a Change Set was started, it was not completed by the former administrator. A developer is brought in to finish the deployment. What should the developer do to identify the configuration changes that need to be moved into production?

Use the Metadata API and a supported development IDE to push all of the configuration from the sandbox into production to ensure no changes are lost.

Leverage the Setup Audit Trail to review the changes made by the departed Administrator and identify which changes should be added to the Change Set.

In Salesforce setup, look at the last modified date for every object to determine which should be added to the Change Set.

Set up Continuous Integration and a Git repository to automatically merge all changes from the sandbox metadata with the production metadata.

Which two actions should the developer take to prevent the business logic that obtains the high value opportunities from being repeated in more than one place? Choose 2 answers

Use custom metadata to hold the high value amount.

Create a helper class that fetches the high value opportunities.

Leave the business logic code inside the trigger for efficiency.

Call the trigger from the Lightning web component.

For example, to compare the Name field of an Account and an Opportunity; or the Name of an Account and a Contact. Assuming the Name field exists, how should the developer do this?

Cast each object into an sObject and use sobject.get ('Name') to compare the Name fields.

Invoke a Schema.describe() function to compare the values of each Name field.

Use the Salesforce Metadata API to extract the value of each object and compare the Name fields.

Use a String.replace() method to parse the contents of each Name field and then compare the results.

There is an Apex controller and a Visualforce page in an org that displays records with a custom filter consisting of a combination of picklist values selected by the user. The page takes too long to display results for some of the input combinations, while for other input choices it throws the exception, "Maximum view state size limit exceeded" What step should the developer take to resolve this issue?

Use a StandardSetController or SOQL LIMIT in the Apex controller to limit the number of records displayed at a time.
