Question 610
At Brookside Manufacturing, the production analytics data team maintains a plant inventory and factory operations database estate with requirements for planned outages and accurate production reporting. The operations owner asks for a validation result for: A team overwrites the only usable full database backup with an unverified new file and discovers it is corrupt during an outage. Which observed result BEST proves the intended problem is corrected?
Explanation
Correct Answer
A recovery drill successfully restores from a retained earlier copy even when a deliberately damaged latest backup is rejected. That observable result supports resolution of: A team overwrites the only usable full database backup with an unverified new file and discovers it is corrupt during an outage. The corresponding corrective change is: Keep independent protected backup copies with retention and routinely verify backups through actual restore tests. The Brookside Manufacturing reviewer can distinguish demonstrated database behavior from an untested change claim.
Incorrect Answers
A native BACKUP TO URL operation writes a usable backup and a subsequent test RESTORE FROM URL passes validation. That result is evidence for another corrective change: Configure supported secure backup-to-URL authentication and monitor storage access and backup job completion. The alternative problem is: A SQL Server backup is placed into Azure Blob Storage but its credential design uses an expired SAS token and backup jobs silently fail. The current Brookside Manufacturing issue is instead: A team overwrites the only usable full database backup with an unverified new file and discovers it is corrupt during an outage. Its decisive acceptance evidence would be: A recovery drill successfully restores from a retained earlier copy even when a deliberately damaged latest backup is rejected.
A test database restores to a timestamp between full backups using the required ordered log backups without a chain gap. That result is evidence for another corrective change: Create a valid full, differential and transaction-log backup chain with tested restore sequencing appropriate to the required recovery point. The alternative problem is: A SQL Server on Azure VM uses full recovery model but the backup schedule has no transaction log backups and cannot restore to an arbitrary point. The current Brookside Manufacturing issue is instead: A team overwrites the only usable full database backup with an unverified new file and discovers it is corrupt during an outage. Its decisive acceptance evidence would be: A recovery drill successfully restores from a retained earlier copy even when a deliberately damaged latest backup is rejected.
A recovery-point inventory shows the expected separate short-term and long-term options without claiming arbitrary PITR inside old LTR copies. That result is evidence for another corrective change: Differentiate short-term PITR backup retention from long-term weekly, monthly or annual restore points and set policies for each need. The alternative problem is: An Azure SQL backup policy keeps a long-term monthly archive but engineers think it automatically creates daily transaction-level restore points for that entire period. The current Brookside Manufacturing issue is instead: A team overwrites the only usable full database backup with an unverified new file and discovers it is corrupt during an outage. Its decisive acceptance evidence would be: A recovery drill successfully restores from a retained earlier copy even when a deliberately damaged latest backup is rejected.
