NEW QUESTION # 108
You have a container named container1 in an Azure Cosmos DB Core (SQL) API account.
The following is a sample of a document in container1.
{
"studentId": "631282",
"firstName": "James",
"lastName": "Smith",
"enrollmentYear": 1990,
"isActivelyEnrolled": true,
"address": {
"street": "",
"city": "",
"stateProvince": "",
"postal": "",
}
}
The container1 container has the following indexing policy.
{
"indexingMode": "consistent",
"includePaths": [
{
"path": "/*"
},
{
"path": "/address/city/?"
}
],
"excludePaths": [
{
"path": "/address/*"
},
{
"path": "/firstName/?"
}
]
}
For each of the following statements, select Yes if the statement is true. Otherwise, select No.
NOTE: Each correct selection is worth one point.
Answer:
Explanation:
Explanation:
Box 1: Yes
"path": "/*" is in includePaths.
Include the root path to selectively exclude paths that don't need to be indexed. This is the recommended approach as it lets Azure Cosmos DB proactively index any new property that may be added to your model.
Box 2: No
"path": "/firstName/?" is in excludePaths.
Box 3: Yes
"path": "/address/city/?" is in includePaths

NEW QUESTION # 110
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?
Answer: B
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.
Incorrect Answers:
A: checkpointInterval: When set, it defines, in milliseconds, the interval between lease checkpoints. Default is always after each Function call.
C: maxItemsPerInvocation: When set, this property sets the maximum number of items received per Function call. If operations in the monitored collection are performed through stored procedures, transaction scope is preserved when reading items from the change feed. As a result, the number of items received could be higher than the specified value so that the items changed by the same transaction are returned as part of one atomic batch.
NEW QUESTION # 111
You have an Azure subscription that contains an Azure Cosmos DB for NoSQL account named account1.
You plan to configure the Apache Kafka service as a data source for account1.
What should you use to store the Kafka configuration?
Answer: C
Explanation:
Store and use Azure Cosmos DB credentials with Azure Key Vault
If you're using Azure Cosmos DB as your database, you connect to databases, container, and items by using an SDK, the API endpoint, and either the primary or secondary key.
It's not a good practice to store the endpoint URI and sensitive read-write keys directly within application code or configuration file. Ideally, this data is read from environment variables within the host. In Azure App Service, app settings allow you to inject runtime credentials for your Azure Cosmos DB account without the need for developers to store these credentials in an insecure clear text manner.
Azure Key Vault iterates on this best practice further by allowing you to store these credentials securely while giving services like Azure App Service managed access to the credentials. Azure App Service will securely read your credentials from Azure Key Vault and inject those credentials into your running application.
