Question 60
At Juniper Media, the streaming service databases team maintains a content subscriptions and audience reporting platform with requirements for traffic peaks and isolated customer information. The acceptance review requires independent evidence for: A Managed Instance workload is consistently limited by compute and storage throughput but the scaling plan changes only database compatibility level. Which observed result BEST proves the intended problem is corrected?
Explanation
Correct Answer
After the approved service change the instance reports the intended capacity and the benchmark improves the constrained resource metric. That observable result supports resolution of: A Managed Instance workload is consistently limited by compute and storage throughput but the scaling plan changes only database compatibility level. The corresponding corrective change is: Scale the supported SQL Managed Instance hardware and service tier according to measured CPU, memory and I/O bottlenecks. The Juniper Media reviewer can distinguish demonstrated database behavior from an untested change claim.
Incorrect Answers
Representative write transactions achieve the required log and commit latency after the targeted tier or compute adjustment. That result is evidence for another corrective change: Use service-tier and workload metrics to choose a supported Azure SQL performance configuration appropriate for transactional latency. The alternative problem is: An OLTP database is configured with a service tier selected for analytical reporting but short transactions show persistent log-write contention. The current Juniper Media issue is instead: A Managed Instance workload is consistently limited by compute and storage throughput but the scaling plan changes only database compatibility level. Its decisive acceptance evidence would be: After the approved service change the instance reports the intended capacity and the benchmark improves the constrained resource metric.
A representative report reads the relevant date partitions instead of scanning unrelated monthly ranges. That result is evidence for another corrective change: Choose a partition function and aligned indexes based on the actual date predicate and verify partition elimination in execution plans. The alternative problem is: A table is partitioned by an arbitrary identifier although nearly all expensive reports filter on monthly transaction dates. The current Juniper Media issue is instead: A Managed Instance workload is consistently limited by compute and storage throughput but the scaling plan changes only database compatibility level. Its decisive acceptance evidence would be: After the approved service change the instance reports the intended capacity and the benchmark improves the constrained resource metric.
Compute utilization and billing follow the idle and burst pattern while peak requests meet the stated restart-latency requirement. That result is evidence for another corrective change: Evaluate a compatible serverless compute tier with auto-pause or autoscaling settings and explicitly test connection warm-up behavior. The alternative problem is: A sporadic Azure SQL Database remains provisioned at peak compute capacity overnight even though long idle periods are predictable. The current Juniper Media issue is instead: A Managed Instance workload is consistently limited by compute and storage throughput but the scaling plan changes only database compatibility level. Its decisive acceptance evidence would be: After the approved service change the instance reports the intended capacity and the benchmark improves the constrained resource metric.
