Correct Answer:

SQL Database query results are cached in Azure Cache for Redis to improve performance.

The application consists of the following Azure services:

Requirements

The application components must meet the following requirements:

• Azure Cosmos DB development must use a native API that receives the latest updates and stores data in a document format.

• Costs must be minimized for all Azure services.

• Developers must test Azure Blob Storage integrations locally before deployment to Azure Testing must support the latest versions of the Azure Storage APIs.

Corporate website

• User authentication and authorization must allow one-time passcode sign-in methods and social identity providers (Google or Facebook).

• Static web content must be stored closest to end users to reduce network latency.

Inventory items

• Customized items read from Azure Cosmos DB must maximize throughput while ensuring data is accurate for the current user on the website.

• Processing of inventory item updates must automatically scale and enable updates across an entire Azure Cosmos DB container.

• Inventory items must be processed in the order they were placed in the queue.

• Inventory item images must be stored as JPEG files in their native format to include exchangeable image file format (data) stored with the blob data upon upload of the image file.

• The Inventory Items API must securely access the Azure Cosmos DB data.

Orders

• Orders must receive inventory item changes automatically after inventory items are updated or saved.

Issues

• Developers are storing the Azure Cosmos DB credentials in an insecure clear text manner within the Inventory Items API code.

• Production Azure Cache for Redis maintenance has negatively affected application performance.

You are developing an application that use an Azure blob named data to store application data. The application creates blob snapshots to allow application state to be reverted to an earlier state.

The Azure storage account has soft deleted enabled.

The system performs the following operations in order:

• The blob is updated

• Snapshot 1 is created.

• Snapshot 2 is created.

• Snapshot 1 is deleted.

A system error then deletes the data blob and all snapshots.

You need to determine which application states can be restored.

What is the restorability of the application data? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.

Reveal Solution Hide Solution

Correct Answer:

Explanation:

Box 1: Can be restored

When enabled, soft delete enables you to save and recover your data when blobs or blob snapshots are deleted. This protection extends to blob data that is erased as the result of an overwrite.

Box 2: Cannot be restored

It has been deleted.

Box 3: Can be restored

It has not been deleted.

Explanation:

Box 1: eventgrid

To create event subscription use: az eventgrid event-subscription create

Box 2: event-subscription

Box 3: servicebusqueue

Scenario: Azure Service Bus and Azure Event Grid

Azure Event Grid must use Azure Service Bus for queue-based load leveling.

Events in Azure Event Grid must be routed directly to Service Bus queues for use in buffering.

Events from Azure Service Bus and other Azure services must continue to be routed to Azure Event Grid for processing.
