Designing and Implementing Cloud-Native Applications Using Microsoft Azure Cosmos DB Questions 41–45 (page: 10)

Updated On: 10-Feb-2026

Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution. After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen. You have a container named container1 in an Azure Cosmos DB Core (SQL) API account. You need to make the contents of container1 available as reference data for an Azure Stream Analytics job. Solution: You create an Azure Synapse pipeline that uses Azure Cosmos DB Core (SQL) API as the input and Azure Blob Storage as the output.
Does this meet the goal?

  1. Yes
  2. No

Answer(s): B

Explanation:

Instead create an Azure function that uses Azure Cosmos DB Core (SQL) API change feed as a trigger and Azure event hub as the output.
The Azure Cosmos DB change feed is a mechanism to get a continuous and incremental feed of records from an Azure Cosmos container as those records are being created or modi ed. Change feed support works by listening to container for any changes. It then outputs the sorted list of documents that were changed in the order in which they were modi ed.
The following diagram represents the data ow and components involved in the solution:

You have an Azure Cosmos DB Core (SQL) API account.
The change feed is enabled on a container named invoice.
You create an Azure function that has a trigger on the change feed.
What is received by the Azure function?

  1. only the changed properties and the system-de ned properties of the updated items
  2. only the partition key and the changed properties of the updated items
  3. all the properties of the original items and the updated items
  4. all the properties of the updated items

Answer(s): B

Explanation:

Change feed is available for each logical partition key within the container.
The change feed is sorted by the order of modi cation within each logical partition key value.

DRAG DROP (Drag and Drop is not supported).
You have an Azure Synapse Analytics workspace named workspace1 that contains a serverless SQL pool.
You have an Azure Table Storage account that stores operational data.
You need to replace the Table storage account with Azure Cosmos DB Core (SQL) API. The solution must meet the following requirements:
Support queries from the serverless SQL pool.
Only pay for analytical compute when running queries.
Ensure that analytical processes do NOT affect operational processes.
Which three actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.
Select and Place:

  1. See Explanation section for answer.

Answer(s): A

Explanation:



Step 1: Create an Azure Cosmos DB core (SQL) API account
Step 2: Enable Azure Synapse Link
Synapse Link creates a tight seamless integration between Azure Cosmos DB and Azure Synapse Analytics. Serverless SQL pool allows you to query and analyze data in your Azure Cosmos DB containers that are enabled with Azure Synapse Link. You can analyze data in near real-time without impacting the performance of your transactional workloads.
Step 3: Create a database and a container that has Analytical store enabled
Create an analytical store enabled container
