AZ-800 Exam Dumps - Microsoft Certified: Windows Server Hybrid Administrator Associate Questions and Answers

The exam materials explain that to add a new domain controller to an existing AD DS forest in Azure, you deploy a Windows Server IaaS VM and then promote it: “To extend on-premises AD DS into Azure, provision a Windows Server VM in Azure and run AD DS to create an additional domain controll er for the existing domain.” Conversely, Azure Active Directory Domain Services (Azure AD DS) provides a managed domain that is separate from and not writable by your on-premises administrators —you “do not get domain admin rights or access to DCs” —so it cannot be used to add a DC (dc3.corp.fabrikam.com) to the existing corp.fabrikam.com forest. Azure AD Application Proxy and Azure AD administrative units are unrelated to deploying DCs. Therefore, the correct implementation is to deploy an Azure virtual machine in Vnet1, install AD DS/DNS, and promote it to become DC3 in the existing domain.

In the Administering Windows Server Hybrid Core Infrastructure materials (hybrid security and IaaS management), Just-In-Time (JIT) VM access from Microsoft Defender for Cloud is the prescribed way to require approval-based, time-bound Remote Desktop access to Azure VMs. The guide explains that JIT “locks down inbound traffic to management ports (for example, TCP/3389) and opens them only on request, for a limited time and only from approved source IPs.” Administrators request access; upon approval, Defender for Cloud creates a temporary NSG rule that expires automatically—you specify the maximum allowed window (e.g., 2 hours) and the ports. This matches the requirement: “Ensure that server administ rators request approval before they can establish a Remote Desktop connection to an Azure virtual machine. If the request is approved, the connection must be established within two hours.” Alternatives don’t meet this: PIM governs Azure roles, not VM RDP port exposure; Azure Bastion provides secure RDP/SSH over TLS without public IPs but doesn’t provide approval/time-boxed gating; the Remote Desktop extension is for classic Cloud Services and not for policy-driven approval windows. JIT is the least-privilege, policy-enforced solution aligned with the exam’s hybrid security objectives.

One possible solution to configure Hyper-V to ensure that running virtual machines can be moved between SRV1 and SRV2 without downtime is to use Live Migration. Live Migration is a feature of Hyper-V that allows you to move a running virtual machine from one host to another without any noticeable interruption of service. To set up Live Migration between SRV1 and SRV2, you need to perform the following steps:

On both SRV1 and SRV2, open Hyper-V Manager from the Administrative Tools menu or by typing virtmgmt.msc in the Run box.

In the left pane, right-click on the name of the server and select Hyper-V Settings .

In the Hyper-V Settings dialog box, select Live Migrations in the navigation pane.

Check the box Enable incoming and outgoing live migrations.

Under Authentication protocol, select the method that you want to use to authenticate the live migration traffi c between the servers. You can choose either Kerberos or CredSSP. Kerberos does not require you to sign in to the source server before starting a live migration, but it requires you to configure constrained delegation on the domain controller. CredSSP does not require you to configure constrained delegation, but it requires you to sign in to the source server through a local console session, a Remote Desktop session, or a remote Windows PowerShell session. For more information on how to configure constraine d delegation, see Configure constrained delegation.

Under Performance options, select the option that best suits your network configuration and performance requirements. You can choose either TCP/IP or Compression or SMB. TCP/IP uses a single TCP connectio n for the live migration traffic. Compression uses multiple TCP connections and compresses the live migration traffic to reduce the migration time and network bandwidth usage. SMB uses the Server Message Block (SMB) 3.0 protocol and can leverage SMB featur es such as SMB Multichannel and SMB Direct. For more information on how to choose the best performance option, see Choose a live migration performance option.

Under Advanced Features, you can optionally enable the Use any available network for live migrati on option, which allows Hyper-V to use any available network adapter on the source and destination servers for live migration. If you do not enable this option, you need to specify one or more network adapters to be used for live migration by clicking on t he Add button and selecting the network adapter from the list. You can also change the order of preference by using the Move Up and Move Down buttons.

Click OK to apply the settings.

Now, you have configured Hyper-V to enable live migration between SRV1 an d SRV2. You can use Hyper-V Manager or Windows PowerShell to initiate a live migration of a running virtual machine from one server to another.

In Azure File Sync architecture (covered in Admin istering Windows Server Hybrid Core Infrastructure under “Implement and manage storage solutions”), the fundamental design points are:

Sync group – “A sync group defines a sync topology. Each sync group contains exactly one cloud endpoint (an Azure file sh are) and one or more server endpoints.” A server endpoint is a folder on a registered Windows Server. A server can participate in multiple sync groups so long as the server endpoints are different paths.

Storage Sync Service – “The Storage Sync Service is the top-level resource that maintains server registrations and houses your sync groups.” A Windows Server registers to one Storage Sync Service at a time, and that service can contain many sync groups and many servers.

Applying these rules to the requirement:

You have three Azure file shares: newyorkfiles, seattlefiles, and companyfiles. Because each sync group maps to one cloud endpoint, you need one sync group per share ⇒ 3 sync groups.

FS1 must sync with newyorkfiles and companyfiles; FS2 must sync with seattlefiles and companyfiles. Since one Storage Sync Service can host multiple sync groups and multiple servers, and a server must be registered to a single service, the most efficient design is a single Storage Sync Service containing all three sync groups and both servers.

The Administering Windows Server Hybrid Core Infrastructure materials explain that Azure AD Password Protection for on-premises AD uses two components : the DC agent and the proxy service . The DC agent is installed on every domain controller because it “ intercepts password set/change operations locally on the DC and evaluates them against the forbidden-password policy .” The guidance further states that to ensure consistent enforcement “ the DC agent should be deployed to all DCs in the forest, since password changes may occur on any DC .” The proxy service is installed on member servers (not necessarily DCs) and “ relays policy downloads and telemetry to Azure AD on behalf of DCs ,” which satisfies envi ronments where “ domain controllers must not directly contact Internet endpoints .” Finally, configuration of the global and custom banned password lists is performed in Azure AD , where administrators “ define tenant-wide custom banned terms; DCs obtain the p olicy via the proxy and cache it for local enforcement .”

Given Fabrikam’s requirement to prevent DCs from accessing the Internet, the proxy must run on non-DC servers ( VM1 and VM2 ). To guarantee enforcement wherever a password is changed, the DC agent must be on all domain controllers . The custom banned password list is configured in the Azure AD tenant and then distributed to on-premises DCs via the proxy.
