第8题:
Backup change tracking will sometimes reduce I/O performed during cumulative incremental backups.
The change tracking file must always be backed up when you perform a full database backup.
Block change tracking will always reduce I/O performed during cumulative incremental backups.
More than one database block may be read by an incremental backup for a change made to a single block.
The incremental level 1 backup that immediately follows the enabling of block change tracking will not read the change tracking file to discover changed blocks.
第9题:
The backup contains all the used blocks.
The backup contains all the used and unused blocks.
The backup contains blocks that have changed since the last level 0 backup.
The backup contains blocks that have changed since the last level 1 backup taken last week.
