Microsoft Installation, Storage, and Compute with Windows Server 2016 (70-740) Practice Test

Understanding how many virtual network adapters you can attach to a Hyper-V VM hinges on the two types of NICs Hyper-V supports: synthetic and emulated. Synthetic adapters are the high-performance option that use the guest’s integration services for fast networking, while emulated adapters provide backward compatibility for guests that don’t have those integration services or are older OSes.

The documented limit for a single Hyper-V virtual machine is twelve network adapters in total. Within that cap, you can configure up to eight synthetic adapters and up to four emulated adapters. This split balances performance (favoring synthetic) with compatibility (allowing some emulated adapters when needed).

So, the best answer reflects that total of twelve adapters, with the distribution being eight synthetic and four emulated. Other totals (like sixteen, eight, or twenty) exceed or don’t meet the supported limit.
