You develop an Azure solution that uses Cosmos DB.
The current Cosmos DB container must be replicated and must use a partition key that is optimized for queries.
You need to implement a change feed processor solution.
Which change feed processor components should you use? To answer, drag the appropriate components to the correct requirements. Each component may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view the content.
NOTE: Each correct selection is worth one point.
Solution:
Graphical user interface, application Description automatically generated
Box 1: The monitored container
The monitored container has the data from which the change feed is generated. Any inserts and updates to the monitored container are reflected in the change feed of the container.
Box 2: The lease container
The lease container acts as a state storage and coordinates processing the change feed across multiple workers. The lease container can be stored in the same account as the monitored container or in a separate account.
Box 3: The host: A host is an application instance that uses the change feed processor to listen for changes. Multiple instances with the same lease configuration can run in parallel, but each instance should have a different instance name.
Box 4: The delegate
The delegate is the code that defines what you, the developer, want to do with each batch of changes that the change feed processor reads.

You are developing a solution that uses the Azure Storage Client library for .NET. You have the following code: (Line numbers are included for reference only.)
For each of the following statements, select Yes if the statement is true. Otherwise, select No.
NOTE: Each correct selection is worth one point.
Solution:
Box 1: Yes
AcquireLeaseAsync does not specify leaseTime.
leaseTime is a TimeSpan representing the span of time for which to acquire the lease, which will be rounded down to seconds. If null, an infinite lease will be acquired. If not null, this must be 15 to 60 seconds.
Box 2: No
The GetBlockBlobReference method just gets a reference to a block blob in this container. Box 3: Yes
The BreakLeaseAsync method initiates an asynchronous operation that breaks the current lease on this container.
