Question 1

You plan to store order data in Azure Cosmos DB for NoSQL account. The data contains information about orders and their associated items.

You need to develop a model that supports order read operations. The solution must minimize the number or requests.

ACreate a single database that contains one container. Store orders and order items in separate documents in the container.

BCreate a single database that contains one container. Create a separate document for each order and embed the order items into the order documents.

CCreate a database for orders and a database for order items.

DCreate a single database that contains a container for order and a container for order items.

Answer : B

Question 2

You need to create a database in an Azure Cosmos DB for NoSQL account. The database will contain three containers named coll1, coll2 and coll3. The coll1 container will have unpredictable read and write volumes. The col!2 and coll3 containers will have predictable read and write volumes. The expected maximum throughput for coll1 and coll2 is 50,000 request units per second (RU/s) each.

How should you provision the collection while minimizing costs?

ACreate a provisioned throughput account. Set the throughput for coll1 to Manual. Set the throughput for coll2 and coll3 to Autoscale.

BCreate a provisioned throughput account. Set the throughput for call1 to Autoscale. Set the throughput for call2 and coll3 to Manual.

CCreate a serverless account.

Answer : B

Question 3

You have a container named container1 in an Azure Cosmos DB for NoSQL account named account1 that is set to the session default consistency level. The average size of an item in container1 is 20 KB.

You have an application named App1 that uses the Azure Cosmos DB SDK and performs a point read on the same set of items in container1 every minute.

You need to minimize the consumption of the request units (RUs) associated to the reads by App1. What should you do?

AIn account1, change the default consistency level to bounded staleness.

BIn App1, change the consistency level of read requests to consistent prefix.

CIn account1, provision a dedicated gateway and integrated cache

DIn App1, modify the connection policy settings.

Answer : B

Question 4

You have an Azure Cosmos DB for NoSQL account named account1 that supports an application named App1. App1 uses the consistent prefix consistency level.

You configure account1 to use a dedicated gateway and integrated cache.

You need to ensure that App1 can use the integrated cache.

Which two actions should you perform for APP1? Each correct answer presents part of the solution.

NOTE: Each correct selection is worth one point.

AChange the connection mode to direct

BChange the account endpoint to https://account1.sqlx.cosmos.azure.com.

CChange the consistency level of requests to strong.

DChange the consistency level of requests to session.

EChange the account endpoint to https://account1.documents.azure.com

Answer : B, D

Question 5

You have a database named db1 in an Azure Cosmos DB f You have a third-party application that is exposed thro You need to migrate data from the application to a What should you use?

ADatabase Migration Assistant

BAzure Data Factory

CAzure Migrate

Answer : B

Question 6

You have an Azure Cosmos DB for NoSQL account1 that is configured for automatic failover. The account1 account has a single read-write region in West US and a and a read region in East US.

You run the following PowerShell command.

What is the effect of running the command?

AA manual failover will occur.

BThe account will be unavailable to writes during the change.

CThe provisioned throughput for account1 will increase.

DThe account will be configured for multi-region writes.

Answer : D

Question 7

You have an Azure Cosmos DB for NoSQL account that has multiple write regions.

You need to receive an alert when requests that target the database exceed the available request units per second (RU/s).

Which Azure Monitor signal should you use?

ARegion Removed

BDocument Quota

CMetadata Requests

DData Usage
