Questions # 32:

You need to securely access inventory items when developing the Inventory Items API.

What are three possible ways to achieve this goal? Each correct answer presents a complete solution.

NOTE: Each correct selection is worth one point.

Options:

Create a custom Microsoft Entra roleAssign the custom role to the Azure Cosmos DB account Update the function app to use certificate-based authentication.

Create a SQL role definition under the Azure Cosmos DB account.Create a user-assigned managed identity and assign the identity to the function app.Assign the user-assigned managed identity the SQL role definition.Update the function app code to implement the DefaultAzurecredential class and reference the user-assigned managed identity.

Create a system-assigned managed identity for the function app with read access to secrets in Azure Key Vault. Store the Azure Cosmos DB primary key and URI in Azure Key Vault as secrets.Use function app settings to reference the secret values.

Create a custom Microsoft Entra role. Assign the custom role to Azure Key Vault. Assign the custom role to the function app.Reference the custom role in the function app code when accessing Azure Key Vault values.

Questions # 36:

You need to save customized items to Azure Cosmos DB.

Which Azure Cosmos DB configuration should you use? To answer, select the appropriate options in the answer area.

NOTE: Each correct selection is worth one point.

Question # 36

Options:

Answer

Answer:

Explanation

1. API:

NoSQL

Reasoning: Since the development must use a native API that stores data in a document format, the NoSQL API is the correct choice. Azure Cosmos DB's NoSQL API stores data in JSON documents and is the most commonly used API for document-based use cases, which aligns with the storage of customized items in the scenario.

2. Consistency Level:

Session

Reasoning: The scenario requires that customized items maximize throughput while ensuring that the data is accurate for the current user. Session consistency provides the best balance between performance and data accuracy for scenarios where multiple reads and writes are performed by the same user session. It ensures that a user reads their own writes, which is important for ensuring that customized items are accurate for the current user.

Final Answer:

API: NoSQL

Consistency level: Session

Questions # 37:

You need to support local development testing for developers. Which tool should you use?

Options:

Azurite

Azure Storage Emulator

SQL Server Management Studio (SSMS)

Azure Storage Explorer

Answer

Questions # 38:

You need to add code at line PC26 of Processing.cs to ensure that security policies are met.

How should you complete the code that you will add at line PC26? To answer, select the appropriate options in the answer area.

NOTE: Each correct selection is worth one point.

Question # 38

Options:

Answer

Answer:

Explanation

Box 1: var key = await Resolver.ResolveKeyAsyn(keyBundle,KeyIdentifier.CancellationToken.None);

Box 2: var x = new BlobEncryptionPolicy(key,resolver);

Example:

// We begin with cloudKey1, and a resolver capable of resolving and caching Key Vault secrets.

BlobEncryptionPolicy encryptionPolicy = new BlobEncryptionPolicy(cloudKey1, cachingResolver);

client.DefaultRequestOptions.EncryptionPolicy = encryptionPolicy;

Box 3: cloudblobClient. DefaultRequestOptions.EncryptionPolicy = x;

Questions # 39:

You need to ensure receipt processing occurs correctly.

What should you do?

Options:

Use blob properties to prevent concurrency problems

Use blob SnapshotTime to prevent concurrency problems

Use blob metadata to prevent concurrency problems

Use blob leases to prevent concurrency problems

Answer

Explanation

You can create a snapshot of a blob. A snapshot is a read-only version of a blob that's taken at a point in time. Once a snapshot has been created, it can be read, copied, or deleted, but not modified. Snapshots provide a way to back up a blob as it appears at a moment in time.

Scenario: Processing is performed by an Azure Function that uses version 2 of the Azure Function runtime. Once processing is completed, results are stored in Azure Blob Storage and an Azure SQL database. Then, an email summary is sent to the user with a link to the processing report. The link to the report must remain valid if the email is forwarded to another user.

Questions # 40:

You need to ensure the security policies are met.

What code do you add at line CS07 of ConfigureSSE.ps1?

Options:

–PermissionsToKeys create, encrypt, decrypt

–PermissionsToCertificates create, encrypt, decrypt

–PermissionsToCertificates wrapkey, unwrapkey, get

–PermissionsToKeys wrapkey, unwrapkey, get

Answer

Explanation

Scenario: All certificates and secrets used to secure data must be stored in Azure Key Vault.

You must adhere to the principle of least privilege and provide privileges which are essential to perform the intended function.

The Set-AzureRmKeyValutAccessPolicy parameter -PermissionsToKeys specifies an array of key operation permissions to grant to a user or service principal. The acceptable values for this parameter: decrypt, encrypt, unwrapKey, wrapKey, verify, sign, get, list, update, create, import, delete, backup, restore, recover, purge
