When getting ready for the exam, focus on understanding how to choose the right data migration solution based on data set size and network bandwidth.
Start by knowing the options for large data sets. If the network is low bandwidth or there are policy restrictions on direct connectivity, look into the Azure Import-Export Service or data box solutions.
For high bandwidth networks, think 1 to 100 gig in speed, tools like AZ Copy, Data Factory, Azure Stack Edge, and Data Box Gateway are great tools to use.
Now let’s say you have smaller data sets, a few gig to a few terabytes. For that, you can use tools like the Azure Storage Explorer, AZ Copy, and Azure CLI.
So make sure you can match the right tool to the data set size and network conditions. This is going to be a core key component that you’ll need to know.
