You create an application that lets users upload photographs and movies to Azure storage. The media is uploaded to a blob storage account named Account1 via a storage REST API call. Container1 and Container2 are two blob storage containers that you have.
Video uploading is done on a sporadic basis.
When particular requirements are met, you must copy specific blobs from Container1 to Container2 in real time, omitting backup blob copies.
What are your options?

Accepted Answer

Run the Azure PowerShell command Start-AzureStorageBlobCopy

Answer

Answer

Using the Blob Service REST API's Put Blob operation, copy blobs to Container2

Question 7

You're responsible for an Azure Web App that runs within a container. The container uses a Dockerfile that is copied all over the place and takes up a lot of space. The Dockerfile must be optimized.
What are your options?

Accepted Answer

Answer

Concatenate all RUN instructions on one line to reduce layers

Answer

Use a.dockerignore file to configure the CLI

Question 8

You're working on an Azure Batch solution to do computations that require a lot of processing power. The calculations take place at a set time each week and last around an hour.
A timer must be created before any adjustments are made to determine the initial duration. Before the first calculation is scheduled to run on the compute node, the timer must start.
The timer must be implemented.
Should the timer be started before or after which line?

Accepted Answer
