    Restore Active Directory Services

    1. C. The user account will retain the SID, the GUID, and all other parameters that form the security principal.

    A, B, and D are incorrect because these limitations do not apply.

    2. A. Non-authoritative restore can be used to restore system Registry and other system services, but not Active Directory data in a single domain with more than one domain controller.

    B and C are incorrect because this will restore older Active Directory data and assign it higher priority over replication. Even if the data is fresh, this operation will cause unnecessary replication traffic. D is incorrect because the ERD process is not used in Windows Server 2008.

    3. B and D. Using these methods, you can increase USNs by a comfortable margin to make sure they get higher priority over previously restored authoritative data.

    A and C are incorrect because you will need to use the verinc option.

    4. A. The AD database is stored in ntds.dit.

    B is incorrect, since a SAM file only stores a local user account database and is not used on a domain controller. C is incorrect because edb.log contains only transaction records. You may argue rather successfully that transaction log data is database data, but technically, the transaction log is a temporary storage of changes to data—the final destination is still the data file. D is incorrect because MFT does not store any user data, only system data necessary to maintain the file system.

    5. C is the correct answer. Starting with Windows Server 2008, the ntbackup utility has been replaced with wbadmin, which now can be used as an integrated system state backup and recovery solution.

    A is incorrect because ntdsutil is not able to perform a full backup of the system state but is used to perform other operations with and within AD (ntdsutil can create snapshots of AD DS, which are a point-in-time copies of AD DS). B is incorrect, because this utility is discontinued and is not shipped with Windows Server 2008. D is incorrect because dcpromo is used to deploy or remove AD DS, not back it up.
