correct answer creates an outage

[An-L]

Your organization has a domain named tutorialsdojo.com.

You want to host your records in Microsoft Azure.

Which actions should you perform?
(Select THREE.)
Create an Azure public DNS zone – right
Copy the Azure DNS A records – apparently wrong
Update the Azure NS records to your domain registrar – apparently right
Update the Azure NSEC records to your domain registrar – wrong
Copy the Azure DNS NS records – right
Create an Azure private DNS zone – wrong
“

However this would cause an outage. Create an empty Azure DNS zone. Explicitly don’t copy your DNS (A) records over, apparently. Now change your registrar to point to Azure zone.

Can you see what the problem is here?
