Question 90
At Alpine Healthcare, the clinical database operations team maintains a hybrid healthcare scheduling and records platform with requirements for patient confidentiality and high service availability. The acceptance review requires independent evidence for: A 12 TB production database must move to Azure with a near-zero outage requirement, but the plan uses backup and restore during a short maintenance window. Which observed result BEST proves the intended problem is corrected?
Explanation
Correct Answer
The last synchronization lag and cutover outage remain within objectives and source-to-target validation shows no missing committed data. That observable result supports resolution of: A 12 TB production database must move to Azure with a near-zero outage requirement, but the plan uses backup and restore during a short maintenance window. The corresponding corrective change is: Choose an online migration strategy with supported continuous synchronization and a timed cutover consistent with downtime and compatibility limits. The Alpine Healthcare reviewer can distinguish demonstrated database behavior from an untested change claim.
Incorrect Answers
The signed-off cutover log proves the agreed recovery point and reconciles final source and target transaction counts. That result is evidence for another corrective change: Define a cutover protocol to quiesce writes, confirm synchronization, record the recovery point and switch only after validation. The alternative problem is: A hybrid migration loses writes because engineers stop applications before verifying the final transaction synchronization and recovery checkpoint. The current Alpine Healthcare issue is instead: A 12 TB production database must move to Azure with a near-zero outage requirement, but the plan uses backup and restore during a short maintenance window. Its decisive acceptance evidence would be: The last synchronization lag and cutover outage remain within objectives and source-to-target validation shows no missing committed data.
The target passes consistency and row-count checks before the archived application is pointed at the restored database. That result is evidence for another corrective change: Use an offline migration plan such as backup and restore or a supported database transfer after checking platform compatibility. The alternative problem is: A static historical archive needs a one-time move with a long approved outage, but engineers propose persistent replication infrastructure. The current Alpine Healthcare issue is instead: A 12 TB production database must move to Azure with a near-zero outage requirement, but the plan uses backup and restore during a short maintenance window. Its decisive acceptance evidence would be: The last synchronization lag and cutover outage remain within objectives and source-to-target validation shows no missing committed data.
The new database reaches the expected state on the destination instance and integrity and application checks match the source. That result is evidence for another corrective change: Select the currently supported Managed Instance database copy or move mechanism after checking edition, region and feature requirements. The alternative problem is: An Azure SQL Managed Instance database move is attempted with a tool that does not support the selected source and destination pairing. The current Alpine Healthcare issue is instead: A 12 TB production database must move to Azure with a near-zero outage requirement, but the plan uses backup and restore during a short maintenance window. Its decisive acceptance evidence would be: The last synchronization lag and cutover outage remain within objectives and source-to-target validation shows no missing committed data.
