The exhibit shows that Site2 does not have a PDC emulator. This is important because of the close interaction between the RID operations master role and the PDC emulator role. The PDC emulator processes password changes from earlier-version clients and other domain controllers on a best-effort basis; handles password authentication requests involving passwords that have recently changed and not yet been replicated throughout the domain; and, by default, synchronizes time. If this domain controller cannot connect to the PDC emulator, this domain controller cannot process authentication requests, it may not be able to synchronize time, and password updates cannot be replicated to it. The PDC emulator master processes password changes from client computers and replicates these updates to all domain controllers throughout the domain. At any time, there can be only one domain controller acting as the PDC emulator master in each domain in the forest.

It takes 3 discs (minimum) in order to create a storage pool array with parity. If this array were using fixed provisioning, this would not be enough given the 256MB capacity (since only 2/3rds of 256 X 3 - less than 600 - could be used as actual data with the rest being parity bits), but since this array uses thin provisioning, a 600GB volume could technically be set up on a 20GB disc and it would still show as 600GB. (So, essentially, the question really becomes how many drives it takes in a storage pool to create a parity array.) References:http://technet.microsoft.com/en-us/library/hh831391.aspxhttp://www.ibeast.com/content/tools/RaidCalc/RaidCalc.asphttp://www.raid-calculator.com/default.aspxhttps://www.icc-usa.com/raid-calculator
