[All AZ-303 Questions]

HOTSPOT -
A company runs multiple Windows virtual machines (VMs) in Azure.
The IT operations department wants to apply the same policies as they have for on-premises VMs to the VMs running in Azure, including domain administrator permissions and schema extensions.
You need to recommend a solution for the hybrid scenario that minimizes the amount of maintenance required.
What should you recommend? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.

Suggested Answer:
Box 1: Join the VMs to a new domain controller VM in Azure
Azure provides two solutions for implementing directory and identity services in Azure:
(Used in this scenario) Extend your existing on-premises Active Directory infrastructure to Azure, by deploying a VM in Azure that runs AD DS as a Domain

Controller. This architecture is more common when the on-premises network and the Azure virtual network (VNet) are connected by a VPN or ExpressRoute connection.
✑ Use Azure AD to create an Active Directory domain in the cloud and connect it to your on-premises Active Directory domain. Azure AD Connect integrates your on-premises directories with Azure AD.
Box 2: Set up VPN connectivity.
This architecture is more common when the on-premises network and the Azure virtual network (VNet) are connected by a VPN or ExpressRoute connection.

You need to recommend a solution for the hybrid scenario that minimizes the amount of maintenance required. So Join the Azure VMs on On Prem AD connected via VPN

Sure, but i think we still need a domain controller in the cloud net hence why the answer talks about connecting the VMs to a DC and then joining the 2 nets via VPN

1. VM should join domain, not domain controller. 2. No need setup a DC in Azure as far as DNS of VM points to on prem DC over VPN.

You can connect these VMs to on-premise domain via VPN, but you have to set the DNS server for all Azure VMs, and it is not mentioned in the question. I think setup a AD DS in an Azure VM is a better solution for many Azure VMs. https://4sysops.com/archives/join-an-azure-vm-to-an-on-prem-active-directory/

correct. I report an explanation for the same question given in another test as part of an az-303 course on udemy: "Here since we want to cut down on maintenance costs, we can connect the virtual machines in Azure directly onto the on-premises domain. We can’t use Azure Active Directory Domain Services because it does not support schema extensions." I verified on microsoft documentation and it's correct

Shouldn't the answer in box 1 be "join the VMs to AD DS" ?

I could definately see connecting directely over the VPN working and you could argue that it will reduce maintenace. However, framing the question from a Microsoft best practice exam question, I can't see MS suggesting connecting your Azure VM's directly over a single non-resilitant VPN WAN link and Im pretty sure they would expect a local DC and AD Site in Azure to handle Authentication etc if the VPN was down. So while 1&1 would work I think MS would be looking for 2&1.

https://docs.microsoft.com/en-us/azure/architecture/reference-architectures/identity/ The Azure AD directory is not an extension of an on-premises directory. Rather, it's a copy that contains the same objects and identities. Changes made to these items on-premises are copied to Azure AD, but changes made in Azure AD are not replicated back to the on-premises domain. Join to existing on-premises domain Minimise maintenance so connection is VPN then

The right way to do it would be another DC in Azure - so you can join the domain with less latency - however more headache to setup, create a new site blah blah. Simply creating a S2S VPN and then just joining them to the domain would also work and be the least maintenance A and A (or 1 and 1 which ever you prefer)

"hybrid scenario that minimizes the amount of maintenance" Why on earth would you create a new domain controller!?!

new DC in Azure is "prettiest", because of reduced latency, but is definitely not minimizing maintenance, because you would have another VM to manage. I'd go with vpn+connect to on-premises.

You Don't join a machine to a specific "domain controller", you join it to a domain. The answer can never be "join to a domain controller".

This document gives this explanation: i think B and A are correct Azure provides two solutions for implementing directory and identity services in Azure: Use Azure AD to create an Active Directory domain in the cloud and connect it to your on-premises Active Directory domain. Azure AD Connect integrates your on-premises directories with Azure AD. Extend your existing on-premises Active Directory infrastructure to Azure, by deploying a VM in Azure that runs AD DS as a Domain Controller. This architecture is more common when the on-premises network and the Azure virtual network (VNet) are connected by a VPN or ExpressRoute connection. Several variations of this architecture are possible: Create a domain in Azure and join it to your on-premises AD forest. Create a separate forest in Azure that is trusted by domains in your on-premises forest. Replicate an Active Directory Federation Services (AD FS) deployment to Azure.

Why you create another domain controller in cloud instead of joining the vms on cloud directly to on-premises AD?

For minimal maintenance you would just use the on-premise domain and that requires a VPN. A and A are correct. The work to do this requires the set up of DNS solution in Auzre and configuring your VMs correctly but this isn't on going work i.e. it's not maintenance.
