問題文
You must design recovery for the directory so that the organization can recover from the loss of an entire site as well as from accidental object deletion. Which combination is appropriate?
選択肢
- Domain controllers in more than one site, application-consistent backups of at least one domain controller per domain kept offsite, and the Recycle Bin enabled for object-level recovery.
- A single domain controller with frequent checkpoints, since checkpoints can restore any state.
- Replication to a second site only, since every change including a deletion is carried to the other site within minutes and the surviving copy can be promoted back into a full directory after the loss of the first site.
- The Recycle Bin alone, since it can restore any deletion including a whole domain.
