Exam AZ-204 topic 2 question 20 discussion

B: the change feed provides 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, a durable, immutable, read-only log of these changes. You can process these logs asynchronously, incrementally or in-full.

Correct Answer: B The 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.

I think B is correct now, but I see copy operation and guessed that's not a change.

Ans --> A Enabling the change feed on the storage account) might not be the ideal choice for asynchronously processing transaction logs of blob changes for auditing purposes, compared to using Azure Event Grid: Change Feed vs. Azure Event Grid: Enabling the change feed on the storage account provides a log of blob changes, but it's designed more for data replication and integration scenarios rather than real-time event processing. Azure Event Grid, on the other hand, is specifically tailored for event-driven architectures and can deliver near real-time notifications about blob operations, which is crucial for auditing purposes where timeliness and reliability of events matter.

B) As stated by Exam topics. They also provide the link to the Learn resource. Highly recommend reading it. One of the best Learn articles I've come across! https://learn.microsoft.com/en-us/azure/storage/blobs/storage-blob-change-feed?tabs=template

Exactly what Change Feed offers

B. Enable the change feed on the storage account and process all changes for available events. Azure Blob storage change feed provides a log of all the create, update, delete, and copy operations that occur on blobs and blob metadata in the storage account. It allows you to track the changes to the blobs in the order in which they occurred, which is what you need for auditing purposes. By enabling the change feed, your application can asynchronously process the changes and retain them for compliance reasons. You can also use Azure Event Grid to route the change feed events to a subscriber Azure Function app for further processing, this way you can keep the logs for the compliance reasons.

B - Because change feed contains an ordered list of operations that have been made in a storage account.

B is correct answer.

B : The 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.

Correct.

What about the delete operations that are not logged by the change feed?

enabled change feed to get information and for auditing or compliance purpose
