Exam AZ-204 topic 4 question 22 discussion

B looks correct. Common Blob storage event scenarios include image or video processing, search indexing, or any file-oriented workflow. Asynchronous file uploads are a great fit for events. When changes are infrequent, but your scenario requires immediate responsiveness, event-based architecture can be especially efficient. https://docs.microsoft.com/en-us/azure/storage/blobs/storage-blob-event-overview

Correct Answer: B The Start-AzureStorageBlobCopy cmdlet starts to copy a blob. Reference: https://docs.microsoft.com/en-us/powershell/module/azure.storage/start-azurestorageblobcopy?view=azurermps-6.13.0 https://docs.microsoft.com/en-us/azure/storage/blobs/storage-blob-event-overview

The correct answer is B. Create an Event Grid topic that uses the Start-AzureStorageBlobCopy cmdlet. Azure Event Grid can react to relevant events across both Azure and non-Azure services in near-real time fashion. You can create an Event Grid subscription on the blob storage account (Account1) to trigger a function when a new blob (video) is uploaded. This function can use the Start-AzureStorageBlobCopy cmdlet to start an asynchronous copy of the blob from Container1 to Container2. Option A, using the Put Blob operation, would require downloading and re-uploading the blob, which is not efficient for large blobs like videos. Option C, using AzCopy with the Snapshot switch, would create a read-only snapshot of the blob, not a writable copy. Option D, downloading the blob to a virtual machine and then uploading it to Container2, would also be inefficient for large blobs and would require unnecessary compute resources.

Got this in exam today (5 April 2023)

Question was on exam 2023-03-30

Only B is automated, since this happens on an irregular basis it needs to be automated

B. Create an Event Grid topic that uses the Start-AzureStorageBlobCopy cmdlet

I think the handler then should be a powershell function ?

I do get it is the correct answer but the option looked very weird when I first read it: "B. Create an Event Grid topic that uses the Start-AzureStorageBlobCopy cmdlet". Probably Microsoft guy wanted that effect. I would have said event-grid topic with an Start-AzureStorageBlobCopy event handler. Microsoft wins again.

B is the correct answer.

The automation of the process comes into play. Answer should be (B)

Got this on 04/05/22 (selected B)

Correct Answer B

B looks correct

The Start-AzureStorageBlobCopy cmdlet starts to copy a blob https://docs.microsoft.com/en-us/powershell/module/azure.storage/start-azurestorageblobcopy?view=azurermps-6.13.0 The Put Blob operation creates a new block, page, or append blob, or updates the content of an existing block blob. So in the given options, only Start-AzureStorageBlobCopy cmdlet copies the blob

B. Create an Event Grid topic that uses the Start-AzureStorageBlobCopy cmdlet

the answer is C in udemy
