  1. See Explanation section for answer.

Answer(s): A

Explanation:



Step 1: Con gure the MaxItemCount in QueryRequestOptions
You can specify the maximum number of items returned by a query by setting the MaxItemCount. The MaxItemCount is speci ed per request and tells the query engine to return that number of items or fewer.
Box 2: Run the query and provide a continuation token
In the .NET SDK and Java SDK you can optionally use continuation tokens as a bookmark for your query's progress. Azure Cosmos DB query executions are stateless at the server side and can be resumed at any time using the continuation token. If the query returns a continuation token, then there are additional query results.
Step 3: Append the results to a variable
