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.

Answer : C

You have an application named App1 that reads the data in an Azure Cosmos DB Core (SQL) API account. App1 runs the same read queries every minute. The default consistency level for the account is set to eventual.

You discover that every query consumes request units (RUs) instead of using the cache.

You verify the IntegratedCacheiteItemHitRate metric and the IntegratedCacheQueryHitRate metric. Both metrics have values of 0.

You verify that the dedicated gateway cluster is provisioned and used in the connection string.

You need to ensure that App1 uses the Azure Cosmos DB integrated cache.

What should you configure?

A.the indexing policy of the Azure Cosmos DB container

B.the consistency level of the requests from App1

C.the connectivity mode of the App1 CosmosClient

D.the default consistency level of the Azure Cosmos DB account

Answer : C

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

NOTE: Each correct selection is worth one point.

A.Configure the trigger for each function to use a different leaseCollectionPrefix

B.Configure the trigger for each function to use the same leaseCollectionNair.e

C.Configure the trigger for each function to use a different leaseCollectionName

D.Configure the trigger for each function to use the same leaseCollectionPrefix

Answer : A, B

You have a container named container1 in an Azure Cosmos DB Core (SQL) API account.

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

Answer:A
