That different risk does not best characterize the missing control in the given scenario.

Use available query and resource metrics to compare pre-change and post-change memory behavior would instead apply to another SQL platform issue, such as when an Azure SQL workload begins consuming more memory after a new query deployment. The present requirement calls for collect an operational baseline for CPU I/O waits duration and transaction throughput; this alternative changes a different control and does not directly resolve the stated database issue.

Configure Azure Monitor metrics and action groups with meaningful capacity thresholds would instead apply to another SQL platform issue, such as when a Managed Instance team needs alerts when storage space approaches a configured ceiling.

Capture blocking sessions and waits with approved diagnostic tooling would instead apply to another SQL platform issue, such as when a DBA needs to examine long-lived SQL blocking chains during a workload spike. The present requirement calls for collect an operational baseline for CPU I/O waits duration and transaction throughput; this alternative changes a different control and does not directly resolve the stated database issue.

Evaluate IQP feature behavior under the database compatibility level and workload would instead apply to another SQL platform issue, such as when a DBA has an Intelligent Query Processing feature available but lacks representative regression tests.
