Show Suggested Answer Hide Answer
Suggested Answer:
Box 1: Server2 -
Incorrect:
Not Server 1: If you've deployed Azure AD Password Protection Proxy, do not install Azure AD Application Proxy and Azure AD Password Protection Proxy together on the same machine. Azure AD Application Proxy and Azure AD Password Protection Proxy install different versions of the Azure AD Connect Agent
Updater service. These different versions are incompatible when installed together on the same machine.
Server1 runs the Azure AD application Proxy connector.
To use Application Proxy, you need a Windows server running Windows Server 2012 R2 or later. You'll install the Application Proxy connector on the server. This connector server needs to connect to the Application Proxy services in Azure, and the on-premises applications that you plan to publish.
Scenario:
Requirements. Authentication Requirements include:
Enforce MFA when accessing on-premises applications.
Existing Environment. On-premises Environment
The on-premises network contains the servers shown in the following table.

Existing Environment. Identity Environment
The network contains an Active Directory forest named litware.com that is linked to an Azure Active Directory (Azure AD) tenant named litware.com. Azure AD
Connect uses pass-through authentication and has password hash synchronization disabled.
Litware.com contains a user named User1 who oversees all application development.

Box 2: DC1 -
The Azure AD Password Protection proxy service is typically on a member server in your on-premises AD DS environment. Once installed, the Azure AD
Password Protection proxy service communicates with Azure AD to maintain a copy of the global and customer banned password lists for your Azure AD tenant.

Correct answer is Server 2, then Azure AD. The password protection proxy is installed on a member server. You enable the banned p/w list in Azure AD, the proxy downloads it and passes it to the DCs in the domain.

Agree with the majority here: Custom banned password list is configured on Azure AD, now Entra ID portal BTW the first part is very suspect, because AD Connect also has the "Microsoft Entra Connect Agent Updater" service as part of its installation routine. In real life you'd prefer a separate, additional member server. https://learn.microsoft.com/en-us/entra/identity/hybrid/verify-sync-tool-version

The password lists is created in Azure AD and then copied to the sysvol on the Domain Controller. https://learn.microsoft.com/en-us/entra/identity/authentication/howto-password-ban-bad-on-premises-operations And...

It is a SERVER 2 answer ! Here is written very clear : !! Warning !!! Azure AD Password Protection proxy and Azure AD Application Proxy install different versions of the Microsoft Azure AD Connect Agent Updater service, which is why the instructions refer to Application Proxy content. These different versions are incompatible when installed side by side and doing so will prevent the Agent Updater service from contacting Azure for software updates, so you should never install Azure AD Password Protection Proxy and Application Proxy on the same machine. https://learn.microsoft.com/en-us/azure/active-directory/authentication/howto-password-ban-bad-on-premises-deploy

Reasons why we need Password protection service on Server 2: DC1: this usually doesnt have connectivity to internet, so not an viable option Server1: please keep in mind that AAD password protection service and AAD Application proxy uses different versions of AAD. Gives rise to compatiblity issue Server2: only possible option left

The question says: "Connect uses pass-through authentication and has password hash synchronization disabled." It means that ADDS is doing the authentication. How the Azure AD will be asked if the password is in banned list? Your link says nothing about hybrid environment as we have here. The link in the answer has the information.

Check this link, https://learn.microsoft.com/en-us/azure/active-directory/authentication/concept-password-ban-bad-on-premises Under "How Azure AD PP works" you will find this, The DC Agent service is responsible for initiating the download of a new password policy from Azure AD. The first step is to locate an Azure AD Password Protection Proxy service by querying the forest for proxy serviceConnectionPoint objects. and if you keep reading, you will find that there is no such thing as a password banned listed on-prem for modification. Everything is downloaded from Azure AD With that, I will stay with -Server2 -Azure AD

If you read their reasoning for choosing The DC, it is still clear that the list is downloaded from Azure Box 2: DC1 - The Azure AD Password Protection proxy service is typically on a member server in your on-premises AD DS environment. Once installed, the Azure AD Password Protection proxy service communicates with Azure AD to maintain a copy of the global and customer banned password lists for your Azure AD tenant.
