Does this meet the goal?

Note: This question is part of a series of questions that present the same scenario. Each question in the series
contains a unique solution. Determine whether the solution meets the stated goals.
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 Azure AD Connect server to an Azure virtual machine that uses a new SQL Server
instance. You set the Azure AD Connect server to staging mode.
Does this meet the goal?

A.
Yes

B.
No

Explanation:
Azure AD Connect sync Staging mode can be used for several scenarios, including:
* High availability.
* Test and deploy new configuration changes.
* Introduce a new server and decommission the old.
If you have a more complex environment, then having one or more standby servers is recommended. During
installation, you can enable a server to be in staging mode.
* Use virtual machines
A common and supported method is to run the sync engine in a virtual machine. In case the host has an issue,
the image with the sync engine server can be migrated to another server.
