Answer: The 5 Flexible Single Master Operation (FSMO) roles are divided into Forest-wide (Schema Master, Domain Naming Master) and Domain-wide (PDC Emulator, RID Master, Infrastructure Master). If the PDC Emulator goes offline, time synchronization, password changes, and GPO edits stall immediately across the domain. If the Schema Master fails, schema modifications (like extending AD for Exchange or LAPS) cannot occur, but daily domain operations continue normally until seized or restored.
Answer: PHS synchronizes a double-hashed version of user passwords to Entra ID, allowing authentication even if on-prem DC goes down. PTA validates passwords directly against on-prem DCs via lightweight agents without storing passwords in the cloud. AD FS is a federated identity provider offering complex claim rules, smart card support, and on-prem MFA, though Microsoft recommends migrating to PHS + Conditional Access for modern zero-trust security.
Answer: Loopback processing applies User Configuration settings based on the Computer object’s OU location (ideal for terminal servers, kiosks, or lab PCs). In Merge Mode, the user’s normal GPO user settings apply first, followed by the computer OU’s user settings (resolving conflicts in favor of the computer OU). In Replace Mode, the user’s regular user GPOs are completely ignored, applying strictly the user configuration settings configured on the computer object’s OU.
Answer: Quorum determines the minimum number of voting elements required for a cluster to remain operational. Dynamic Quorum automatically adjusts node vote allocations as nodes go down or come back online. Dynamic Witness adjusts the File Share or Cloud Witness vote based on whether the total node vote count is odd or even, maintaining an odd total vote count to prevent a 50/50 split-brain tie.
