Explanation:
Box 1: Yes
"path": "/*" is in includePaths.
Include the root path to selectively exclude paths that don't need to be indexed. This is the recommended approach as it lets Azure Cosmos DB proactively index any new property that may be added to your model.
Box 2: No
"path": "/firstName/?" is in excludePaths.
Box 3: Yes
"path": "/address/city/?" is in includePaths

Explanation:
Step 1: Configure the MaxItemCount in QueryRequestOptions You can specify the maximum number of items returned by a query by setting the MaxItemCount. The MaxItemCount is specified 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

You plan to create an Azure Cosmos DB for NoSQL account that will have a single write region and three read regions.
You need to set the consistency level for the account. The solution must meet the following requirements:
- In the write region, writes must replicate synchronously across at
least three replicas.
- In the read regions, reads must see writes in order for transactional batches.
- Throughput for reads and writes must be maximized.
Which consistency level should you select?
