QUESTION 1:

You have a container named container1 in an Azure Cosmos DB Core (SQL) API account.
You need to provide a user named User1 with the ability to insert items into container1 by using role-based access control (RBAC). The solution must use the principle of least privilege.
Which roles should you assign to User1?

A. CosmosDB Operator only
B. DocumentDB Account Contributor and Cosmos DB Built-in Data Contributor
C. DocumentDB Account Contributor only
D. Cosmos DB Built-in Data Contributor only

Correct Answer: A

Cosmos DB Operator: Can provision Azure Cosmos accounts, databases, and containers. Cannot access any data or use Data Explorer.

Incorrect Answers:

B: DocumentDB Account Contributor can manage Azure Cosmos DB accounts. Azure Cosmos DB is formerly known as DocumentDB.

C: DocumentDB Account Contributor: Can manage Azure Cosmos DB accounts.

QUESTION 2:

You have an Azure Cosmos DB Core (SQL) API account.
You run the following query against a container in the account.
SELECT IS_NUMBER(“1234”) AS A,
IS_NUMBER(1234) AS B,
IS_NUMBER({prop: 1234}) AS C
What is the output of the query?

A. [{“A”: false, “B”: true, “C”: false}]
B. [{“A”: true, “B”: false, “C”: true}]
C. [{“A”: true, “B”: true, “C”: false}]
D. [{“A”: true, “B”: true, “C”: true}]

Correct Answer: A

IS_NUMBER returns a Boolean value indicating if the type of the specified expression is a number. “1234” is a string, not a number.

QUESTION 3:

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?

A. Yes
B. No

Correct Answer: B

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 modified. 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 modified.

QUESTION 4:

HOTSPOT
You have a database in an Azure Cosmos DB Core (SQL) API account.
You plan to create a container that will store employee data for 5,000 small businesses. Each business will have up to 25 employees. Each employee item will have an email address value.
You need to ensure that the email address value for each employee within the same company is unique.
To what should you set the partition key and the unique key? To answer, select the appropriate options in the answer area.

NOTE: Each correct selection is worth one point.
Hot Area:

Correct Answer:

Box 1: CompanyID After you create a container with a unique key policy, the creation of a new or an update of an existing item resulting in a duplicate within a logical partition is prevented, as specified by the unique key constraint. The partition key combined with the unique key guarantees the uniqueness of an item within the scope of the container.
For example, consider an Azure Cosmos container with an Email address as the unique key constraint and CompanyID as the partition key. When you configure the user\’s email address with a unique key, each item has a unique email address within a given CompanyID. Two items can\’t be created with duplicate email addresses and with the same partition key value.

Box 2: emailAddress

Reference: https://docs.microsoft.com/en-us/azure/cosmos-db/unique-keys

QUESTION 5:

HOTSPOT
You have a database in an Azure Cosmos DB SQL API Core (SQL) account that is used for development.
The database is modified once per day in a batch process.
You need to ensure that you can restore the database if the last batch process fails. The solution must minimize costs.
How should you configure the backup settings? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.

Correct Answer:

QUESTION 6:

HOTSPOT
You plan to deploy two Azure Cosmos DB Core (SQL) API accounts that will each contain a single database. The accounts will be configured as shown in the following table.

How should you provision the containers within each account to minimize costs? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Hot Area:

Correct Answer:

Box 1: Serverless capacity mode Azure Cosmos DB serverless best fits scenarios where you expect intermittent and unpredictable traffic with long idle times. Because provisioning capacity in such situations isn\’t required and may be cost-prohibitive, Azure Cosmos DB serverless should be considered in the following use-cases:

  1. Getting started with Azure Cosmos DB
  2. Running applications with bursty, intermittent traffic that is hard to forecast, or low (
