A custom web resource displays a list of 10,000 active accounts. The current implementation retrieves all fields for all records, and the page loads slowly. You need to improve performance while still displaying the required account name and city. What should you do?

Retrieve all records and filter them client-side

Use the $select query parameter to retrieve only the name and address1_city fields

Use $expand to include related records

Use $top=100 to limit the results

A data migration tool must insert 100,000 records into Dataverse. The tool currently sends individual requests and takes hours. You need to reduce the total time while staying within API limits. What should you do?

Use parallel individual requests with no batching

Use the Organization service's CreateRequest for each record

Send all 100,000 records in a single ExecuteMultipleRequest

Use ExecuteMultipleRequest with batches of 100 records and a retry policy
