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.

A. 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.

B. 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.

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

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

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






 

Suggested Answer: BE

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.
Incorrect Answers:
"Enable blob versioning for the storage account. Use an Azure Function to process a list of the blob versions per day": You can enable Blob storage versioning to automatically maintain previous versions of an object. When blob versioning is enabled, you can access earlier versions of a blob to recover your data if it is modified or deleted.
