NEW QUESTION # 55
You have a database in an Azure Cosmos DB Core (SQL) API account.
You need to create an Azure function that will access the database to retrieve records based on a variable named accountnumber. The solution must protect against SQL injection attacks.
How should you define the command statement in the function?
Answer: B
Explanation:
Azure Cosmos DB supports queries with parameters expressed by the familiar @ notation. Parameterized SQL provides robust handling and escaping of user input, and prevents accidental exposure of data through SQL injection.
For example, you can write a query that takes lastName and address.state as parameters, and execute it for various values of lastName and address.state based on user input.
SELECT *
FROM Families f
WHERE f.lastName = @lastName AND f.address.state = @addressState

NEW QUESTION # 56
You have an Azure Cosmos DB for NoSQL account named account1 that has a single write region in the East US Azure region and read regions in the West Europe and Southeast Asia Azure regions. Service-managed failover is enabled, and the West Europe region is highest in the failover priority list.
You have an app named App1 that uses the Azure Cosmos DB .NET SDK.
You need to minimize how long it takes for App1 to resume writes after a regional outage. The solution must meet the following requirements:
- Ensure that read latency is optimized for the West Europe and
Southeast Asia regions.
- Minimize code changes for App1.
What should you do?
Answer: D
Explanation:
To satisfy all constraints, you should enable multi-region writes on the Azure Cosmos DB account
[assume this already done] and configure the ApplicationRegion property in the .NET SDK client initialization.
Resuming Writes Instantly: With multi-region writes enabled, every region becomes a valid write location. If the primary region experiences an outage, active-active capability prevents the database from performing a traditional database-level failover. This lowers write recovery time to zero since alternate regions can immediately ingest traffic.
*-> Optimized Read and Write Latency: Passing the ApplicationRegion property (e.g., Regions.WestEurope) to the SDK allows it to locate the nearest active geographic replica. This guarantees low-latency local reads and writes within West Europe and Southeast Asia.
*-> Minimal Code Changes: Instead of hardcoding complex prioritized lists via ApplicationPreferredRegions, setting the single ApplicationRegion string automatically creates an ordered fallback list behind the scenes based on geographic proximity.

NEW QUESTION # 57
You have an Azure Cosmos DB for NoSQL account that contains a container named customers.
You have an application named App1 that caches customers and must be notified when the list of customers changes.
You implement a change feed. The Time to Live settings have the default values.
You discover the following:
* Notifications for INSERT and UPDATE operations are received within 10 seconds.
* Notifications for DELETE operations are NOT received.
Which two actions should you perform to ensure that App1 receives notifications for DELETE operations?
Each correct answer present part of the solution.
NOTE: Each correct selection is worth one point.
Answer: C,D
NEW QUESTION # 58
You have a container that stores data about families. The following is a sample document.
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
Children who do no have parents defined will appear on the list = NO
Children who do not have parents defined will not appear on the list. This is because the document schema defines the children property as an array of objects that contain the firstName and gender properties of each child, as well as a parents property that references the id values of the parents. If a child does not have parents defined, it means that the parents property is either missing or empty for that child. Therefore, such a child will not be included in the list of children who have parents defined.
Children who have more than one pet will appear on the list multiple times. = Yes Children who have more than one pet will appear on the list multiple times. This is because the document schema defines the pets property as an array of objects that contain the givenName and type properties of each pet, as well as a children property that references the id values of the children who own the pet. If a child has more than one pet, it means that the child's id value will appear in the children property of multiple pet objects. Therefore, such a child will be included in the list of children who have pets multiple times.
Children who do no have pets defined will appear on the list = No
Children who do not have pets defined will not appear on the list. This is because the document schema defines the pets property as an array of objects that contain the givenName and type properties of each pet, as well as a children property that references the id values of the children who own the pet. If a child does not have pets defined, it means that the child's id value does not appear in the children property of any pet object.
Therefore, such a child will not be included in the list of children who have pets defined.
NEW QUESTION # 59
You have an Azure Cosmos DB Core (SQL) API account named account1 that has the disableKeyBasedMetadataWriteAccess property enabled.
You are developing an app named App1 that will be used by a user named DevUser1 to create containers in account1. DevUser1 has a non-privileged user account in the Azure Active Directory (Azure AD) tenant.
You need to ensure that DevUser1 can use App1 to create containers in account1.
What should you do? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.

Explanation
Box 1: Resource tokens
Resource tokens provide access to the application resources within a database. Resource tokens:
Provide access to specific containers, partition keys, documents, attachments, stored procedures, triggers, and UDFs.
Box 2: Azure Resource Manager API
You can use Azure Resource Manager to help deploy and manage your Azure Cosmos DB accounts, databases, and containers.
