問題文
A cluster holds two migratable targets that both migrate on their own, one under each of the two automatic policies. An administrator shuts down, and shuts down gracefully, the server that both targets name as their preferred host. What becomes of the two services?
選択肢
- One of them starts on another server of the candidate list while the other does not move at all, since only the first of the two policies keeps a service active after a shutdown by hand
- Neither of them moves, since both of the policies wait for that same server to fail from an error inside it and read a shutdown by hand as a planned absence
- Both of them start on another server of the candidate list, since a graceful shutdown of the preferred host counts as a failure of that host under either of the two policies, and neither of them waits for an error inside the host
- One of them starts on another server of the candidate list while the other is restarted on the host that is going down, since the second policy holds a service to its preferred host at any cost
