Question # 1



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}]




A.   

[{"A": false, "B": true, "C": false}]



Explanation:
IS_NUMBER returns a Boolean value indicating if the type of the specified expression is a
number.
"1234" is a string, not a number.
Reference: https://docs.microsoft.com/en-us/azure/cosmos-db/sql/sql-query-is-number




Question # 2



You need to implement a trigger in Azure Cosmos DB Core (SQL) API that will run before
an item is inserted into a container.
Which two actions should you perform to ensure that the trigger runs? Each correct answer
presents part of the solution.
NOTE: Each correct selection is worth one point.

A.

Append pre to the name of the JavaScript function trigger.

B.

For each create request, set the access condition in RequestOptions.

C.

Register the trigger as a pre-trigger.

D.

For each create request, set the consistency level to session in RequestOptions.

E.

For each create request, set the trigger name in RequestOptions.




C.   

Register the trigger as a pre-trigger.



Explanation:
C: When triggers are registered, you can specify the operations that it can run with.
F: When executing, pre-triggers are passed in the RequestOptions object by specifying
PreTriggerInclude and then passing the name of the trigger in a List object.
Reference: https://docs.microsoft.com/en-us/azure/cosmos-db/sql/how-to-use-storedprocedures-
triggers-udfs




Question # 3



You have an Azure Cosmos DB Core (SQL) API account that uses a custom conflict
resolution policy. The account has a registered merge procedure that throws a runtime
exception.
The runtime exception prevents conflicts from being resolved.
You need to use an Azure function to resolve the conflicts.
What should you use?

A.

a function that pulls items from the conflicts feed and is triggered by a timer trigger

B.

a function that receives items pushed from the change feed and is triggered by an Azure
Cosmos DB trigger

C.

a function that pulls items from the change feed and is triggered by a timer trigger

D.

a function that receives items pushed from the conflicts feed and is triggered by an Azure Cosmos DB trigger




D.   

a function that receives items pushed from the conflicts feed and is triggered by an Azure Cosmos DB trigger



Explanation: The Azure Cosmos DB Trigger uses the Azure Cosmos DB Change Feed to
listen for inserts and updates across partitions. The change feed publishes inserts and
updates, not deletions.
Reference: https://docs.microsoft.com/en-us/azure/azure-functions/functions-bindingscosmosdb




Question # 4



You have a container named container1 in an Azure Cosmos DB Core (SQL) API account. Upserts of items in container1 occur every three seconds.
You have an Azure Functions app named function1 that is supposed to run whenever items
are inserted or replaced in container1.
You discover that function1 runs, but not on every upsert.
You need to ensure that function1 processes each upsert within one second of the upsert.
Which property should you change in the Function.json file of function1?

A.

checkpointInterval

B.

leaseCollectionsThroughput

C.

maxItemsPerInvocation

D.

feedPollDelay




D.   

feedPollDelay



Explanation:
With an upsert operation we can either insert or update an existing record at the same
time.
FeedPollDelay: The time (in milliseconds) for the delay between polling a partition for new
changes on the feed, after all current changes are drained. Default is 5,000 milliseconds, or
5 seconds.
Reference: https://docs.microsoft.com/en-us/azure/azure-functions/functions-bindingscosmosdb-
v2-trigger




Question # 5



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?

 

A.

Yes

B.

No




B.   

No



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.
The following diagram represents the data flow and components involved in the solution:

solution




Question # 6



You have the indexing policy shown in the following exhibit.




Question # 7



You have an Azure Cosmos DB Core (SQL) API account that is used by 10 web apps.
You need to analyze the data stored in the account by using Apache Spark to create
machine learning models. The solution must NOT affect the performance of the web apps.
Which two actions should you perform? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.

A.

In an Apache Spark pool in Azure Synapse, create a table that uses cosmos.olap as the
data source.

B.

Create a private endpoint connection to the account.

C.

In an Azure Synapse Analytics serverless SQL pool, create a view that uses
OPENROWSET and the CosmosDB provider.

D.

Enable Azure Synapse Link for the account and Analytical store on the container.

E.

In an Apache Spark pool in Azure Synapse, create a table that uses cosmos.oltp as the
data source.




A.   

In an Apache Spark pool in Azure Synapse, create a table that uses cosmos.olap as the
data source.




D.   

Enable Azure Synapse Link for the account and Analytical store on the container.

Question # 8



You have a database in an Azure Cosmos DB Core (SQL) API account. The database is
backed up every two hours.
You need to implement a solution that supports point-in-time restore.
What should you do first?

A.

Enable Continuous Backup for the account.

B.

Configure the Backup & Restore settings for the account.

C.

Create a new account that has a periodic backup policy.

D.

Configure the Point In Time Restore settings for the account.




A.   

Enable Continuous Backup for the account.



Reference: https://docs.microsoft.com/en-us/azure/cosmos-db/provision-accountcontinuous-
backup




Question # 9



You have an Azure Cosmos DB Core (SQL) API account named storage1 that uses
provisioned throughput capacity mode.
The storage1 account contains the databases shown in the following table.




Question # 10



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 an Azure Cosmos DB Core (SQL) API account named account 1 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?

A.

Yes

B.

No




A.   

Yes



Explanation:
You can set up alerts from the Azure Cosmos DB pane or the Azure Monitor service in the
Azure portal.
Note: Alerts are used to set up recurring tests to monitor the availability and
responsiveness of your Azure Cosmos DB resources. Alerts can send you a notification in
the form of an email, or execute an Azure Function when one of your metrics reaches the
threshold or if a specific event is logged in the activity log.
