Your network contains a single Active Directory forest. The forest contains a domain controller and Active
Directory Federation Services (AD FS) servers that are deployed to virtual machines. The virtual machines run
either on-premises or on Microsoft Azure.
You have Azure AD Connect deployed on-premises. The Azure AD Connect database is installed on an onpremises instance of Microsoft SQL Server 2014.
Last month, an Azure AD Connect server experienced a hardware failure that caused an Azure AD Connect
server to go offline for several days.
You need to recommend a solution to reduce the outage window when hardware failure occurs on the Azure
AD Connect server.
Solution: You deploy a new on-premises Azure AD Connect server that uses the same SQL Server instance.
You start Azure AD Connect sync.
Does this meet the goal?
A.
Yes
B.
No
Explanation:

No because of this?
For those of you with knowledge of older sync technologies, the staging mode is different since the server has its own SQL database. This architecture allows the staging mode server to be located in a different datacenter

“Having multiple Azure AD Connect sync servers connected to the same Azure AD tenant is not supported, except for a staging server. It’s unsupported even if these servers are configured to synchronize with a mutually exclusive set of objects. You might have considered this topology if you can’t reach all domains in the forest from a single server, or if you want to distribute load across several servers.”
Having the sync run on multiple servers is not supported. The new server should be set to staging mode. Hence the answer is no..
