In the Administering Windows Server Hybrid Core Infrastructure material under Windows Remote Management/PowerShell Remoting and authentication, Microsoft describes the classic "second-hop" issue:
when you start a remote session to Server2 using Kerberos and then try to reach a resource on Server3, " your delegated credentials are not forwarded by default." The guide explains that Kerberos "does not allow delegation unless it is explicitly configured," and the recommended domain-based solution is Kerberos constrained delegation (KCD). With KCD you "permit a specific computer account to delegate a user's Kerberos credentials only to explicitly listed services," for example allowing Server2 (the WinRM
/HTTP endpoint you connect to) to delegate to CIFS on Server3 so file or other resource access succeeds during the second hop.
The docs contrast this with alternatives: CredSSP can work but "is broader in exposure and requires enabling a less restrictive credential delegation mechanism," while JEA limits what commands can be run and does not solve credential delegation. Selective authentication applies to forest trusts, and Enforce user logon restrictions relates to KDC validation and is not a remedy for second-hop delegation. Because the requirement is to pass credentials from Server1 # Server2 # Server3 with minimal administrative touch and preserve security boundaries, configuring Kerberos constrained delegation on Server2's computer account for the target services on Server3 is the correct approach.

Volume for the AD DS database: F
Caching configuration for the volume that hosts the database: NONE
The Administering Windows Server Hybrid Core Infrastructure guidance for deploying AD DS on Azure IaaS VMs is explicit about storage placement and disk caching. The study materials state that you must not use the temporary disk and should place the AD DS database and logs on a persistent data disk:
"Do not place the Active Directory database, logs, or SYSVOL on the temporary disk (typically D: in Azure).
Data on the temporary disk is not persistent and can be lost at any time." They also direct disabling host caching on the disk that holds the AD DS database and logs to maximize resiliency and avoid write-caching data loss:
"For disks that store NTDS.dit and the AD DS log files, configure Host caching = None to prevent stale or unflushed writes and to ensure directory integrity during failures." And, for drive layout:
"Install the operating system on C: and create a separate data disk/volume for AD DS database and logs to improve reliability and recoverability." Applying these verified practices:
* Selecting F: (the new persistent data disk) meets the requirement to avoid the non-persistent D: drive and to separate AD DS from the OS volume (C:).
* Setting host caching to NONE on that disk maximizes resiliency and prevents accidental data loss by disabling volatile write caching for critical AD DS data.

In the Administering Windows Server Hybrid Core Infrastructure guidance for "Implement and manage AD DS sites and replication," Microsoft explains that client computers are site-aware and "select domain controllers in their own site whenever possible." A client's site membership is determined solely by the mapping of its IP subnet to an AD DS site. The material further notes that administrators should "create subnet objects and associate them to the appropriate site so that clients resolve and authenticate to DCs in that site; if a subnet is not mapped, clients may use any reachable site through site coverage." By creating a new subnet object for the branch office and associating it with Site1, all clients in that subnet will treat Site1 as their site and will therefore query and authenticate primarily against Site1's domain controllers, only failing over to other sites if necessary via DEFAULTIPSITELINK. This meets the stated goal without requiring domain controllers in the new office, because site affinity controls the preferred DC selection for Kerberos
/NTLM authentication and LDAP/GC queries.

One possible solution to register SRV1 to sync Azure file shares using the 34646045 Storage Sync Service is to use the Register-AzStorageSyncServer cmdlet from the Az.StorageSync module. This cmdlet establishes a trust relationship between the server and the Storage Sync Service, which is required for creating server endpoints and syncing files. Here are the steps to register SRV1 using the cmdlet:
On SRV1, open PowerShell as an administrator and run the following command to install the Az.StorageSync module if it is not already installed:
Install-Module -Name Az.StorageSync
Run the following command to import the Az.StorageSync module:
Import-Module -Name Az.StorageSync
Run the following command to sign in to your Azure account and select the subscription that contains the
34646045 Storage Sync Service:
Connect-AzAccount
Select-AzSubscription -SubscriptionId <your-subscription-id>
Run the following command to register SRV1 with the 34646045 Storage Sync Service. You need to specify the resource group name and the Storage Sync Service name as parameters:
Register-AzStorageSyncServer -ResourceGroupName <your-resource-group-name> - StorageSyncServiceName 34646045 Wait for the registration to complete. You can verify the registration status by checking the Registered servers tab on the Azure portal or by running the following command:
Get-AzStorageSyncServer -ResourceGroupName <your-resource-group-name> -StorageSyncServiceName
34646045
Now, SRV1 is registered with the 34646045 Storage Sync Service and ready to sync Azure file shares. You can create server endpoints on SRV1 and cloud endpoints on the Azure file shares to define the sync topology.

Explanation:

The AZ-800 materials explain that group Managed Service Accounts (gMSAs) rely on the KDS (Key Distribution Service) to generate and rotate passwords. Therefore, in a new forest you must first create a KDS root key:
* "Before creating your first gMSA, run Add-KdsRootKey to seed the KDS" (the key may need propagation time).Next, you create the gMSA and scope which computers can retrieve its managed password:
* Use New-ADServiceAccount with -PrincipalsAllowedToRetrieveManagedPassword set to the security group that contains the NLB nodes (here, ITFarmHosts), and specify the DNS host name as needed for the service (e.g., NLBCluster.contoso.com).Finally, on each cluster node you install (register) the gMSA locally so services can run under it:
* Run Install-ADServiceAccount on each server in ITFarmHosts.
Cmdlets like Add-ADComputerServiceAccount are used for standalone MSAs (sMSAs), not gMSAs, and Set-ADForestConfiguration isn't required. This sequence enables the NLB service on all five nodes to authenticate using the gMSA with automatic password management.
