Questions # 71:

You need to implement a solution to resolve the retail store location data issue.

Which three Azure Blob features should you enable? Each correct answer presents part of the solution.

NOTE Each correct selection is worth one point

Options:

Immutability

Snapshots

Versioning

Soft delete

Object replication

Change feed

Answer

C, D, F

Explanation

Scenario: You must perform a point-in-time restoration of the retail store location data due to an unexpected and accidental deletion of data.

Before you enable and configure point-in-time restore, enable its prerequisites for the storage account: soft delete, change feed, and blob versioning.

Questions # 72:

You need to test the availability of the corporate website.

Which two test types can you use?

Options:

Custom testing using the TrackAvailability API method

Standard

URL Ping

Multi-step

Answer

A, B

Questions # 73:

You need to secure the Azure Functions to meet the security requirements.

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

NOTE: Each correct selection is worth one point.

Options:

Store the RSA-HSM key in Azure Cosmos DB. Apery the built-in policies for customer-managed keys and allowed locations.

Create a free tier Azure App Configuration instance with a new Azure AD service principal.

Store the RSA-HSM key in Azure Key Vault with soft-delete and purge-protection features enabled.

Store the RSA-HSM key in Azure Blob storage with an Immutability policy applied to the container.

Create a standard tier Azure App Configuration instance with an assigned Azure AD managed identity.

Answer

C, E

Explanation

Scenario: All Azure Functions must centralize management and distribution of configuration data for different environments and geographies, encrypted by using a company-provided RSA-HSM key.

Microsoft Azure Key Vault is a cloud-hosted management service that allows users to encrypt keys and small secrets by using keys that are protected by hardware security modules (HSMs).

You need to create a managed identity for your application.

Questions # 74:

You need to audit the retail store sales transactions.

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

NOTE: Each correct selection is worth one point.

Options:

Update the retail store location data upload process to include blob index tags. Create an Azure Function to process the blob index tags and filter by store location

Enable blob versioning for the storage account. Use an Azure Function to process a list of the blob versions per day.

Process an Azure Storage blob inventory report by using an Azure Function. Create rule filters on the blob inventory report,

Subscribe to blob storage events by using an Azure Function and Azure Event Grid. Filter the events by store location.

Process the change feed logs of the Azure Blob storage account by using an Azure Function. Specify a time range for the change feed data.

Answer

D, E

Explanation

Scenario: Audit store sale transaction information nightly to validate data, process sales financials, and reconcile inventory.

"Process the change feed logs of the Azure Blob storage account by using an Azure Function. Specify a time range for the change feed data": Change feed support is well-suited for scenarios that process data based on objects that have changed. For example, applications can:

Store, audit, and analyze changes to your objects, over any period of time, for security, compliance or intelligence for enterprise data management.

"Subscribe to blob storage events by using an Azure Function and Azure Event Grid. Filter the events by store location": Azure Storage events allow applications to react to events, such as the creation and deletion of blobs. It does so without the need for complicated code or expensive and inefficient polling services. The best part is you only pay for what you use.

Blob storage events are pushed using Azure Event Grid to subscribers such as Azure Functions, Azure Logic Apps, or even to your own http listener. Event Grid provides reliable event delivery to your applications through rich retry policies and dead-lettering.

Questions # 75:

You need to implement the delivery service telemetry data

How should you configure the solution?

NOTE: Each correct selection is worth one point.

Question # 75

Options:

Answer

Answer:

Questions # 76:

you need to reduce read latency for the retail store solution.

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

NOTE: Each correct selection is worth one point.

Options:

Create a new composite index for the store location data queries in Azure Cosmos DB. Modify the queries to support parameterized SQL and update the Azure function app to call the new Queries.

Configure Azure Cosmos DB consistency to strong consistency Increase the RUs for the container supporting store location data.

Provision an Azure Cosmos OB dedicated gateway, update blob storage to use the new dedicated gateway endpoint.

Configure Azure Cosmos DB consistency to session consistency. Cache session tokens in a new Azure Redis cache instance after every write. Update reads to use the session token stored in Azure Redis.

Provision an Azure Cosmos DB dedicated gateway Update the Azure Function app connection string to use the new dedicated gateway endpoint.

Answer

C, D
