Which of these would manually trigger a synchronization for Azure AD Connect through PowerShell?

• start-adsyncsynccycle -policytype alfa
• start-adsyncsynccycle -policytype delta
• start-adsyncsynccycle -policytype all
• start-adsyncsynccycle 

EXPLANATION

You can still force an export by using the synchronization service manager.
A server in staging mode continues to receive changes from Active Directory and Azure AD. It always has a copy of the latest changes and can very fast take over the responsibilities of another server.
If you make configuration changes to your primary server, it is your responsibility to make the same changes to the server in staging mode.
start-adsyncsynccycle -policytype delta

Which of these is NOT a use case of Microsoft Azure Stack?

• Update and extend legacy applications with modern Azure services on-premise
• Address latency and connectivity requirements for edge and disconnected solutions
• Develop applications and deploy in Azure or on-premises to meet regulatory and policy requirements
• The next-gen Hyper-V platform for you to migrate your current workloads on your existing hardware 

EXPLANATION

If you answered "next-gen Hyper-V platform for you to migrate..." then yes you're correct - that is NOT the intended use case of Microsoft Azure Stack.  Microsoft Windows Server Software Defined (WSSD)
is a better solution to implement virtualization in scale within your datacenter.   Azure Stack's three primary use cases can be found at the link provided to learn more.
