  2. B Any data stored on the minority side of the partition is deemed invalid and is automatically purged upon network recovery.
  3. C Hardware-level distributed locks prevent any new write operations from being accepted until the network is fully stabilized.
  4. D The system must resolve the 'Split Brain' using conflict resolution strategies like Read Repair or Hinted Handoff replays.

One system design question a day, with spaced repetition so the ones you miss come back.
