Question 560
At Riverton Utilities, the infrastructure database operations team maintains a private metering and regulatory reporting system with requirements for change control and loss-bounded recovery. After a claimed fix, the release reviewer evaluates: A financial application must resume within fifteen minutes after an entire region failure but operations has no estimate of DNS and client reconnection delays. Which observed result BEST proves the intended problem is corrected?
Explanation
Correct Answer
A region-failure exercise completes an authenticated business transaction within the fifteen-minute RTO including routing and client recovery. That observable result supports resolution of: A financial application must resume within fifteen minutes after an entire region failure but operations has no estimate of DNS and client reconnection delays. The corresponding corrective change is: Plan the recovery time objective using application routing, database failover, detection and client reconnection behavior end to end. The Riverton Utilities reviewer can distinguish demonstrated database behavior from an untested change claim.
Incorrect Answers
The promoted recovery database sustains the required transaction throughput and client latency instead of merely accepting connections. That result is evidence for another corrective change: Size the recovery replica and network path for the documented recovery workload and run representative failover load tests. The alternative problem is: A cross-region failover plan assumes secondary read replicas will always have identical performance capacity to the primary without sizing them. The current Riverton Utilities issue is instead: A financial application must resume within fifteen minutes after an entire region failure but operations has no estimate of DNS and client reconnection delays. Its decisive acceptance evidence would be: A region-failure exercise completes an authenticated business transaction within the fifteen-minute RTO including routing and client recovery.
The test run records expected operator decisions and the application passes validation after the supported failover sequence. That result is evidence for another corrective change: Document both automatic and manual failover modes with decision authority, dependency checks, service routing and recovery verification. The alternative problem is: A business continuity plan assumes that successful automatic failover means no manual approval, client cache updates or data validation will ever be needed. The current Riverton Utilities issue is instead: A financial application must resume within fifteen minutes after an entire region failure but operations has no estimate of DNS and client reconnection delays. Its decisive acceptance evidence would be: A region-failure exercise completes an authenticated business transaction within the fifteen-minute RTO including routing and client recovery.
A controlled accidental deletion is recovered to a selected pre-deletion timestamp and the restored database is usable. That result is evidence for another corrective change: Include point-in-time restore and appropriate retention planning alongside high-availability features to handle user or application mistakes. The alternative problem is: An Azure SQL Database application has no backup-restore runbook because its developers assume built-in platform availability prevents logical data deletion. The current Riverton Utilities issue is instead: A financial application must resume within fifteen minutes after an entire region failure but operations has no estimate of DNS and client reconnection delays. Its decisive acceptance evidence would be: A region-failure exercise completes an authenticated business transaction within the fifteen-minute RTO including routing and client recovery.
