A. There's not a right or wrong answer to this question, but there are several advantages to making the Hyper-V servers members of a domain.
- You can use Failover Clustering (which requires the hosts to be domain joined).
- You can use Kerberos authentication.
- Management will be simplified, because you can use domain credentials.
- Certain services require the Hyper-V host to be domain joined for virtual machine creation, such as in an automated virtual desktop infrastructure (VDI) environment.
Unless you have specific security limitations, such as having Hyper-V in a demilitarized zone (DMZ), most organizations will join their hosts into the domain.
