Which three actions should you perform on DC10?

DRAG DROP
Your network contains an Active Directory forest named contoso.com.
Recently, all of the domain controllers that ran Windows Server 2003 were replaced by domain
controllers that run Windows Server 2012 R2.
From Event Viewer, you discover SYSVOL journal wrap errors on a domain controller named
dc10.contoso.com.
You need to perform a non-authoritative synchronization of SYSVOL on DC10.
Which three actions should you perform on DC10?
To answer, move the three appropriate actions from the list of actions to the answer area and

Explanation:
Box 1:

Box 2:

Box 3:

Note:
(step 1) For an Authoritative Restore you must stop the NTFRS services on all of your DCs
(Step 2) In the registry location:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NtFrs\Parameters\Backup/Restore\Pr
ocess
Set the BurFlags setting to HEX “D4” on a known DC that has a good SYSVOL (or at this time restore
SYSVOL data from backup then set the Burflag to D4)
(step 3) Then start NTFRS on this server.
You may want to rename the old folders with .old extensions prior to restoring good data.
Clean up the folders on all the remaining servers (Policies, Scripts, etc) – renamed them with .old
extensions.
Set the BurFlags to D2 on all remaining servers and then start NTFRS.
Wait for FRS to replicate.
Clean up the .old stuff if things look good.
If the “D4″ won’t solve the problem try the “D2″ value.

    If you are using DFRS or FRS is the question here. You are told that you have upgraded – if the migration from FRS (windows 2000) to DFRS (Windows 2012) has been done we don’t know. I would have migratet to DFRS when moving to Windows 2012 + DC’s

    Another twisted MS question, in this case luring you to mix up FRS, DFS and DFRS (!). It’s advised to carefully read before answering.

    Beside a domain level raise usually an admin would also migrate to DFRS when upgrading from 2003 to 2012 DCs.

  3. Progenitor says:

    Indeed another tricky question. Let’s discuss this.

    There is no indication, about the domain functional level or if it has been raised or notes about migration from FRS to DFS-R. As the 2003 DCs have been replaced by Server 2012 R2, we have to assume, there is still FRS for the Sysvol replication in place.

    But to use DFS-R a minimum domain functional level of Windows Server 2003 R2 is required. ( https://msdn.microsoft.com/en-us/library/cc731545 ) and this exam is for Server 2012 R2. DFS-R seems to be the more “logical” choice and the notice of 2003 may be just a distraction.

    But let me cite 2 arguments: First, you cannot edit the “msDFSR-Enabled=FALSE” Attribute, required for the non-authoritative restore with DFR-R, by registry – You have to use ADSIEdit.
    Second, setting the global BurFlag to D2 (for non-authoritative restore) ( https://support.microsoft.com/de-de/kb/2218556 ) will not affect DFS-R anymore – only FRS.

    So, Stop the File Replication Service (FRS) service, Modify the registry, Start the File Replication Service (FRS) service is the only possible solution left.

    Just my 2c

  4. hawkens says:

    The question states that the servers were replaced, not upgraded. So I asume DFS is rebuild on the 2012 servers?

    If this is correct then E, D, F schuld be the correct answer.

    https://technet.microsoft.com/en-us/library/jj127250%28v=ws.11%29.aspx

    Deprecated feature

    Replacement

    DFS Namespaces command-line tool, Dfscmd

    DFS Namespaces module for Windows PowerShell

    File Replication Service (FRS)

    DFS Replication

    In Windows Server 2012 R2, it is no longer possible to use Windows PowerShell or Server Manager to create new domains with a Windows Server 2003 domain functional level. This means that new FRS deployments are now blocked and DFS Replication will always be used for SYSVOL replication in new domains.

    so correct answer is
    Stop DFS
    Edit registry
    Start DFS

    I believe the answer given is correct as it specifies ‘Edit Registry’ not adsiedit.

    With FRS you could edit the switch with the regedit however with DFS you could not adsiedit is required.

    As adsiedit is not an option provided it can not be DFS, the only complete working solution is the provided answer.

      From Event Viewer, you discover SYSVOL journal wrap errors on a domain controller named dc10.contoso.com.

      Would you not “Modify the computer object for DC10 in Active Directory” with adsiedit?

      So wouldn’t the right anwser be:

      Stop DFS
      Edit AD object
      Start DFS

      If DFS is the tech used.

  7. robocopy says:

    1. Servers were _replaced_ (so we have DFS)
    2. It is not mentioned that you have to use ADUC or anything other, so you can use ADSI edit.

    So the answer is:

    1. Stop DFS
    2. Update computer object
    3. Start DFS
