You are having a small pilot group of AVD using FSLogix. The company cut the expenses for the pilot by utilizing Transactional Optimized storage for the Azure file share. Users find that applications are slow and sometimes there are errors. 
Which of the following steps would you take to resolve the issue? 

Answer options:

A.Upgrade the storage account to Azure NetApp files

C.Create a new premium file share, use RoboCopy to migrate existing profiles

Option A is incorrect. You can’t upgrade a storage account to Azure NetApp Files. 
Option B is correct. Enabling large file shares on the storage account is the recommended solution to resolve the identified issue.
