Question 310
An architect proposes this change: Configure active geo-replication to a suitable readable secondary and validate business RPO expectations. The workload context is: A data platform requires near-real-time Azure SQL Database secondary reads in another region, tolerating asynchronous replication lag. Which evidence would most directly validate the change?
- Query the secondary and compare replication lag and failover limitations under controlled writes.
- Locate a long-term retained backup and perform a controlled restore into a test environment.
- Simulate restoring from geo-redundant retained backups to an allowed secondary region.
- Initiate planned failover and test connection string continuity through the failover-group listener.
Explanation
Correct Answer
A:The decisive evidence is: Query the secondary and compare replication lag and failover limitations under controlled writes. This measures the mechanism of the planned change, not an unrelated Azure service: Configure active geo-replication to a suitable readable secondary and validate business RPO expectations.
Incorrect Answers
B:This check validates a different workload: Locate a long-term retained backup and perform a controlled restore into a test environment. Its associated design is: Configure an appropriate Azure SQL long-term backup retention policy matching compliance periods. The required acceptance test here is: Query the secondary and compare replication lag and failover limitations under controlled writes.
C:That observation pertains to a separate failure: Only locally redundant backups exist when the region is inaccessible. Its cause is: Backup redundancy was chosen without aligning regional recovery requirements. It does not confirm the result of this design. The direct proof would be: Query the secondary and compare replication lag and failover limitations under controlled writes.
D:The alternative test targets: Configure an Azure SQL failover group with appropriate primary/secondary databases and supported read-write listener usage. The scenario's actual proposed remedy is: Configure active geo-replication to a suitable readable secondary and validate business RPO expectations. Verify that one by: Query the secondary and compare replication lag and failover limitations under controlled writes.
Question 311
During architecture troubleshooting, a team reports: A regional analytics service cannot read data because only periodic offline backups exist. Context: A data platform requires near-real-time Azure SQL Database secondary reads in another region, tolerating asynchronous replication lag. Which underlying design mistake explains the observed behavior most precisely?
- The application is coupled to a fixed server endpoint instead of the failover-group listener.
- Short-term PITR retention was mistaken for multiyear long-term backup retention.
- Backups are not a continuously readable geo-replicated database copy.
- Backup redundancy was chosen without aligning regional recovery requirements.
Explanation
Correct Answer
C:This is the failure mechanism rather than an incidental symptom: Backups are not a continuously readable geo-replicated database copy. It accounts for: A regional analytics service cannot read data because only periodic offline backups exist. The architectural repair is: Configure active geo-replication to a suitable readable secondary and validate business RPO expectations.
Incorrect Answers
A:The alternative weakness is: The application is coupled to a fixed server endpoint instead of the failover-group listener. Its associated failure is: Clients cannot connect after manual regional failover because they use a region-specific server hostname. Neither explains the present observation: A regional analytics service cannot read data because only periodic offline backups exist. The direct cause here is: Backups are not a continuously readable geo-replicated database copy.
B:This cause would explain a different symptom: The only retained database backups expire weeks before audit evidence is required. The mechanism for that event is: Short-term PITR retention was mistaken for multiyear long-term backup retention. Here the stated symptom is: A regional analytics service cannot read data because only periodic offline backups exist. Its cause is: Backups are not a continuously readable geo-replicated database copy.
D:The alternative weakness is: Backup redundancy was chosen without aligning regional recovery requirements. Its associated failure is: Only locally redundant backups exist when the region is inaccessible. Neither explains the present observation: A regional analytics service cannot read data because only periodic offline backups exist. The direct cause here is: Backups are not a continuously readable geo-replicated database copy.
Question 312
The design change is: Configure active geo-replication to a suitable readable secondary and validate business RPO expectations. The original failure was: A regional analytics service cannot read data because only periodic offline backups exist. Which ongoing control best prevents recurrence of the same root cause?
- Audit backup expiry schedules and long-term restore permissions at compliance reviews.
- Test failover-group listeners and replication health after planned infrastructure changes.
- Review backup redundancy and tested regional restore permissions before business continuity changes.
- Monitor async replication health and clearly document permissible replication lag.
Explanation
Correct Answer
D:The key follow-up control is: Monitor async replication health and clearly document permissible replication lag. It avoids recurrence of the scenario in which: A regional analytics service cannot read data because only periodic offline backups exist. It addresses: Backups are not a continuously readable geo-replicated database copy.
Incorrect Answers
A:The proposed control focuses on: Short-term PITR retention was mistaken for multiyear long-term backup retention. For the design in the question, recurrence comes from: Backups are not a continuously readable geo-replicated database copy. A precise prevention step is: Monitor async replication health and clearly document permissible replication lag.
B:That safeguard manages another risk: The application is coupled to a fixed server endpoint instead of the failover-group listener. Its scenario is: Clients cannot connect after manual regional failover because they use a region-specific server hostname. The present recurring risk is: Backups are not a continuously readable geo-replicated database copy. The proper ongoing control is: Monitor async replication health and clearly document permissible replication lag.
C:This is a reasonable safeguard for a different fault: Only locally redundant backups exist when the region is inaccessible. That different mechanism is: Backup redundancy was chosen without aligning regional recovery requirements. The original incident here instead arises from: Backups are not a continuously readable geo-replicated database copy. The directly relevant safeguard is: Monitor async replication health and clearly document permissible replication lag.
Question 313
A design workshop has this requirement: A production SQL workload needs recovery to a point before accidental table deletion without copying every database to another region. Operators currently observe: Operators assume a database geo-replica can replace every accidental deletion recovery need. Select the ONE design remedy that best addresses the root cause.
- Choose Azure SQL Database when its managed single-database compatibility meets workload requirements.
- Select an Azure SQL backup storage redundancy and recovery strategy that supports the required geo-restore scope.
