Before creating regular ANF volumes, a planner expects more than 11 usable addresses for future storage endpoints. They propose a dedicated /28 delegated subnet. Which planning adjustment is appropriate?

✓ Correct answer

• Choose a larger suitable dedicated delegated subnet, such as /26, before deployment

Plan sufficient delegated address space in advance. The raw subnet size is not the Azure-usable count, and multiple delegated subnets are not a workaround within one VNet. Option explanations: A. Use the session-host subnet without ANF delegation: Regular ANF volumes require their dedicated Microsoft.NetApp/volumes delegation. B. Count all 16 addresses in /28 as usable Azure addresses: Azure reserves addresses, leaving 11 usable in a /28 subnet. C. Choose a larger suitable dedicated delegated subnet, such as /26, before deployment: A /28 offers 11 usable Azure addresses, while /26 offers 59 and more growth room. D. Plan several ANF-delegated subnets in the same VNet for ordinary volume creation: Only one delegated subnet can be used for ANF volume creation per VNet.
