questions will not appear in the review screen.

You have an Azure Cosmos DB for NoSQL account named account1 that uses autoscale throughput.

You need to run an Azure function when the normalized request units per second for a container in account1

exceeds a specific value.

Solution: You configure an Azure Monitor alert to trigger the function.

Does this meet the goal?

Options :

A : Yes

B : No

Answer: A

Question 2

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?

Options :

A : Consistent Prefix

B : Bounded Staleness

C : Eventual

D : Strong

Answer: A

Question 3

You are working on an app that will save the device metrics produced every minute by various IoT devices. You decide to collect the data for two entities; the devices and the device metrics produced by each device. You were about to create two containers for these identified entities but suddenly your data engineer suggests you place both entities in a single container, not two different containers. You would like to be able to track the general data of the device and the number of metrics collections per device. How could we keep track of these entities inside the container?

Options :

A : Add a new property to your device documents called metricscollectioncount and update it with the current number of metrics collection documents. Subtract 1 from the metricscollectioncount property when your app or Azure function adds a new metrics collection

B : Add a new property to your device documents called metricscollectioncount and update it with the current number of metrics collection documents. Add 1 to the metricscollectioncount property inside a transactional batch when your app or Azure function adds a new metrics collectionright

C : Use a GROUP BY parameter in your query and use the aggregate count to return the number of device metrics collections per device

D : Use a GROUP BY parameter in your query and use the aggregate sum to return the number of device metrics collections per device

Answer: B

Question 4

You plan to create an Azure Cosmos DB for NoSQL database named db1 that will contain two containers. One of the containers will contain blog posts, and the other will contain users. Each item in the blog post container will include:

• A single blog post

• The top 10 comments associated to the blog post

• The names of the users who created the blog post and the associated comments

You need to automatically update the usernames in the blog post container whenever a username in the user container changes.

What should you implement for the user container?

Options :

A : a stored procedure

B : a change feed processor

C : a post-trigger

D : a user-defined function (UDF)

Answer: B

Question 5

You have an Azure Cosmos DB database that hosts a container named container1.

You need to ensure that the items stored in container1 will NOT expire unless their TTL value is set explicitly.

What should you do?

Options :

A : Set the DefaultTimeToLive property to 0.

B : Remove the DefaultTimeToLive property.

C : Set the DefaultTimeToLive property to null.

D : Set the DefaultTimeToLive property to –1.
