Your infrastructure divided in 2 sites. You have a forest root domain and child domain. There is only one DC on
site 2 with no FSMO roles. The link goes down to site 2 and no users can log on.
What FSMO roles you need on to restore the access?
A.
Infrastructure master
B.
RID master
C.
Domain Naming master
D.
PCD emulator
Explanation:
D: The PDC emulator is used as a reference DC to double-check incorrect passwords and it also receivesnew
password changes.

6.1.5.4 PDC Emulator FSMO Role
16 out of 20 rated this helpful – Rate this topic
The PDC Emulator FSMO role owner performs the following functions:
Password changes performed by other DCs in the domain are replicated preferentially to the PDC emulator.
If a logon authentication fails at a given DC in a domain due to a bad password, the DC will forward the authentication request to the PDC emulator to validate the request against the most current password. If the PDC reports an invalid password to the DC, the DC will send back a bad password failure message to the user.
Account lockout is processed on the PDC emulator.
The PDC emulator FSMO also fulfills the role of the PDC in the NetLogon Remote Protocol methods described in [MS-NRPC] section 3. Therefore, the PDC emulator FSMO MUST support and perform all PDC specific functionality specified in that section. Every DC, other than the PDC emulator FSMO, MUST NOT perform this functionality.
There is one PDC Emulator FSMO role per domain in a directory. See 3.1.1.7 for more information about the PDC Emulator FSMO role

you would only need a GC.
provisioning a PDC emulator when a link goes down is plain stupid and wouldn’t site1 be unable to logon if you had moved it b4.
Stupid question. still D though.
