Question 450
A SQL Server VM takes a full backup every Sunday and promises five-minute RPO without any transaction-log backup schedule. Which observable result BEST proves the database administration requirement is satisfied?
Explanation
Correct Answer
A complete chain can be restored to the required point using valid full, differential and sequential log backups with proven integrity. This is the observable database and application outcome rather than merely a saved setting. A full backup without subsequent transaction-log backups cannot recover every later transaction; SIMPLE recovery changes log backup support.
Incorrect Answers
A recoverable backup is stored under controlled access and a real restore exercise proves the chain, keys and application consistency requirements. This would validate Backup to Azure Blob URL and tested cloud restore, but it does not establish the required outcome here. Verify instead: A complete chain can be restored to the required point using valid full, differential and sequential log backups with proven integrity.
A restore to the required historical point completes into a supported database target and data plus dependent identities are validated. This would validate Azure SQL automatic PITR and long-term retention, but it does not establish the required outcome here. Verify instead: A complete chain can be restored to the required point using valid full, differential and sequential log backups with proven integrity.
After a planned or forced failover the intended database endpoint serves valid writes and read-only workloads under documented consistency limits. This would validate Azure SQL Database active geo replication and failover groups, but it does not establish the required outcome here. Verify instead: A complete chain can be restored to the required point using valid full, differential and sequential log backups with proven integrity.
