Question 50

At Timberline Foods, the supply-chain data reliability team maintains a distributed purchasing and cold-storage database platform with requirements for verified inventory and low-disruption maintenance. After a claimed fix, the release reviewer evaluates: A database experiences sustained CPU throttling on an underprovisioned Azure SQL Database but administrators increase storage only. Which observed result BEST proves the intended problem is corrected?

  1. Post-scale CPU pressure and request latency improve under a representative test while storage and cost remain within approved bounds.
  2. A representative report reads the relevant date partitions instead of scanning unrelated monthly ranges.
  3. Compute utilization and billing follow the idle and burst pattern while peak requests meet the stated restart-latency requirement.
  4. The database reports adequate free storage after the approved change and no growth operation fails its service limit.

Explanation

Correct Answer

A:

Post-scale CPU pressure and request latency improve under a representative test while storage and cost remain within approved bounds. That observable result supports resolution of: A database experiences sustained CPU throttling on an underprovisioned Azure SQL Database but administrators increase storage only. The corresponding corrective change is: Select an appropriate service tier and compute capacity using observed CPU and workload behavior, with a controlled scale and cost review. The Timberline Foods reviewer can distinguish demonstrated database behavior from an untested change claim.

Incorrect Answers

B:

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 Timberline Foods issue is instead: A database experiences sustained CPU throttling on an underprovisioned Azure SQL Database but administrators increase storage only. Its decisive acceptance evidence would be: Post-scale CPU pressure and request latency improve under a representative test while storage and cost remain within approved bounds.

C:

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 Timberline Foods issue is instead: A database experiences sustained CPU throttling on an underprovisioned Azure SQL Database but administrators increase storage only. Its decisive acceptance evidence would be: Post-scale CPU pressure and request latency improve under a representative test while storage and cost remain within approved bounds.

D:

The database reports adequate free storage after the approved change and no growth operation fails its service limit. That result is evidence for another corrective change: Review independent service-tier compute and storage quotas and scale the supported storage setting or tier as required. The alternative problem is: A managed SQL service's storage approaches its limit and the scaling plan assumes that increasing vCores always increases the allowable data size. The current Timberline Foods issue is instead: A database experiences sustained CPU throttling on an underprovisioned Azure SQL Database but administrators increase storage only. Its decisive acceptance evidence would be: Post-scale CPU pressure and request latency improve under a representative test while storage and cost remain within approved bounds.

Question 51

At Westhaven Retail, the commerce database engineering team maintains a high-volume digital checkout and inventory application with requirements for fast transactions and variable seasonal demand. A routine platform check identifies: A database experiences sustained CPU throttling on an underprovisioned Azure SQL Database but administrators increase storage only. Which action BEST resolves this specific database administration problem?

  1. Evaluate a compatible serverless compute tier with auto-pause or autoscaling settings and explicitly test connection warm-up behavior.
  2. Reconfigure supported VM storage and I/O placement for data, log and tempdb using measured throughput and latency requirements.
  3. Select an appropriate service tier and compute capacity using observed CPU and workload behavior, with a controlled scale and cost review.
  4. Scale the supported SQL Managed Instance hardware and service tier according to measured CPU, memory and I/O bottlenecks.

Explanation

Correct Answer

C:

Select an appropriate service tier and compute capacity using observed CPU and workload behavior, with a controlled scale and cost review. This addresses the specific Azure SQL or SQL Server operational issue: A database experiences sustained CPU throttling on an underprovisioned Azure SQL Database but administrators increase storage only. The Westhaven Retail team should verify the result rather than assume an accepted configuration is sufficient. The decisive acceptance evidence is: Post-scale CPU pressure and request latency improve under a representative test while storage and cost remain within approved bounds.

Incorrect Answers

A:

Evaluate a compatible serverless compute tier with auto-pause or autoscaling settings and explicitly test connection warm-up behavior. That relates to a separate SQL administration problem: A sporadic Azure SQL Database remains provisioned at peak compute capacity overnight even though long idle periods are predictable. The Westhaven Retail requirement is instead: A database experiences sustained CPU throttling on an underprovisioned Azure SQL Database but administrators increase storage only. That approach does not directly establish the required fix; the requested acceptance evidence is: Post-scale CPU pressure and request latency improve under a representative test while storage and cost remain within approved bounds.

B:

Reconfigure supported VM storage and I/O placement for data, log and tempdb using measured throughput and latency requirements. That relates to a separate SQL administration problem: A SQL Server on Azure VM reports elevated storage latency because logs, data and tempdb share a small underprovisioned disk layout. The Westhaven Retail requirement is instead: A database experiences sustained CPU throttling on an underprovisioned Azure SQL Database but administrators increase storage only. That approach does not directly establish the required fix; the requested acceptance evidence is: Post-scale CPU pressure and request latency improve under a representative test while storage and cost remain within approved bounds.

D:

Scale the supported SQL Managed Instance hardware and service tier according to measured CPU, memory and I/O bottlenecks. That relates to a separate SQL administration problem: A Managed Instance workload is consistently limited by compute and storage throughput but the scaling plan changes only database compatibility level. The Westhaven Retail requirement is instead: A database experiences sustained CPU throttling on an underprovisioned Azure SQL Database but administrators increase storage only. That approach does not directly establish the required fix; the requested acceptance evidence is: Post-scale CPU pressure and request latency improve under a representative test while storage and cost remain within approved bounds.

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.

C:

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.

D:

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.
