Demo Questions
Question 1
Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution.
After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.
You develop a software as a service (SaaS) offering to manage photographs. Users upload photos to a web service which then stores the photos in Azure Storage Blob storage. The storage account type is General-purpose V2.
When photos are uploaded, they must be processed to produce and save a mobile-friendly version of the image. The process to produce a mobile-friendly version of the image must start in less than one minute.
You need to design the process that starts the photo processing.
Solution: Convert the Azure Storage account to a BlockBlobStorage storage account.
Does the solution meet the goal?
- Yes
- No
Correct answer: B
Explanation:
Not necessary to convert the account, instead move photo processing to an Azure Function triggered from the blob upload..Azure Storage events allow applications to react to events. Common Blob storage event scenarios include image or video processing, search indexing, or any file-oriented workflow.Note: Only storage accounts of kind StorageV2 (general purpose v2) and BlobStorage support event integration. Storage (general purpose v1) does not support integration with Event Grid.Reference:https://docs.microsoft.com/en-us/azure/storage/blobs/storage-blob-event-overview Not necessary to convert the account, instead move photo processing to an Azure Function triggered from the blob upload..

- Yes
- No
Correct answer: A
Explanation:
Azure Storage events allow applications to react to events. Common Blob storage event scenarios include image or video processing, search indexing, or any file-oriented workflow.Events are pushed using Azure Event Grid to subscribers such as Azure Functions, Azure Logic Apps, or even to your own http listener.Note: Only storage accounts of kind StorageV2 (general purpose v2) and BlobStorage support event integration. Storage (general purpose v1) does not support integration with Event Grid.Reference:https://docs.microsoft.com/en-us/azure/storage/blobs/storage-blob-event-overview Azure Storage events allow applications to react to events.

Question 3
You are developing an application that uses Azure Blob storage.
The application must read the transaction logs of all the changes that occur to the blobs and the blob metadata in the storage account for auditing purposes. The changes must be in the order in which they occurred, include only create, update, delete, and copy operations and be retained for compliance reasons.
You need to process the transaction logs asynchronously.
What should you do?
- Process all Azure Blob storage events by using Azure Event Grid with a subscriber Azure Function app.
- Enable the change feed on the storage account and process all changes for available events.
- Process all Azure Storage Analytics logs for successful blob events.
- Use the Azure Monitor HTTP Data Collector API and scan the request body for successful blob events.
Correct answer: B
Explanation:
Change feed support in Azure Blob StorageThe purpose of the change feed is to provide transaction logs of all the changes that occur to the blobs and the blob metadata in your storage account. The change feed provides ordered, guaranteed, durable, immutable, read-only log of these changes. Client applications can read these logs at any time, either in streaming or in batch mode. The change feed enables you to build efficient and scalable solutions that process change events that occur in your Blob Storage account at a low cost.Reference:https://docs.microsoft.com/en-us/azure/storage/blobs/storage-blob-change-feed Change feed support in Azure Blob Storage
