Question 70

At Granite SaaS, the tenant database platform team maintains a multi-tenant business application backed by Azure SQL with requirements for tenant isolation and consistent provisioning. The operations owner asks for a validation result for: A large rowstore fact table creates I/O pressure because repeated string values are stored uncompressed in cold partitions. Which observed result BEST proves the intended problem is corrected?

  1. The database reports adequate free storage after the approved change and no growth operation fails its service limit.
  2. A representative report reads the relevant date partitions instead of scanning unrelated monthly ranges.
  3. The compression test reduces page reads and allocated space without exceeding the agreed CPU and query latency thresholds.
  4. A comparable transaction test shows lower sustained disk latency and transaction-log write waits without risking data durability.

Explanation

Correct Answer

C:

The compression test reduces page reads and allocated space without exceeding the agreed CPU and query latency thresholds. That observable result supports resolution of: A large rowstore fact table creates I/O pressure because repeated string values are stored uncompressed in cold partitions. The corresponding corrective change is: Evaluate row or page data compression on suitable tables or partitions and measure CPU versus I/O and storage tradeoffs. The Granite SaaS reviewer can distinguish demonstrated database behavior from an untested change claim.

Incorrect Answers

A:

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 Granite SaaS issue is instead: A large rowstore fact table creates I/O pressure because repeated string values are stored uncompressed in cold partitions. Its decisive acceptance evidence would be: The compression test reduces page reads and allocated space without exceeding the agreed CPU and query latency thresholds.

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 Granite SaaS issue is instead: A large rowstore fact table creates I/O pressure because repeated string values are stored uncompressed in cold partitions. Its decisive acceptance evidence would be: The compression test reduces page reads and allocated space without exceeding the agreed CPU and query latency thresholds.

D:

A comparable transaction test shows lower sustained disk latency and transaction-log write waits without risking data durability. That result is evidence for another corrective change: Reconfigure supported VM storage and I/O placement for data, log and tempdb using measured throughput and latency requirements. The alternative problem is: A SQL Server on Azure VM reports elevated storage latency because logs, data and tempdb share a small underprovisioned disk layout. The current Granite SaaS issue is instead: A large rowstore fact table creates I/O pressure because repeated string values are stored uncompressed in cold partitions. Its decisive acceptance evidence would be: The compression test reduces page reads and allocated space without exceeding the agreed CPU and query latency thresholds.

Question 71

At Brookside Manufacturing, the production analytics data team maintains a plant inventory and factory operations database estate with requirements for planned outages and accurate production reporting. The database operations review identifies: A large rowstore fact table creates I/O pressure because repeated string values are stored uncompressed in cold partitions. Which action BEST resolves this specific database administration problem?

  1. Evaluate row or page data compression on suitable tables or partitions and measure CPU versus I/O and storage tradeoffs.
  2. Select an appropriate service tier and compute capacity using observed CPU and workload behavior, with a controlled scale and cost review.
  3. Review independent service-tier compute and storage quotas and scale the supported storage setting or tier as required.
  4. Reconfigure supported VM storage and I/O placement for data, log and tempdb using measured throughput and latency requirements.

Explanation

Correct Answer

A:

Evaluate row or page data compression on suitable tables or partitions and measure CPU versus I/O and storage tradeoffs. This addresses the specific Azure SQL or SQL Server operational issue: A large rowstore fact table creates I/O pressure because repeated string values are stored uncompressed in cold partitions. The Brookside Manufacturing team should verify the result rather than assume an accepted configuration is sufficient. The decisive acceptance evidence is: The compression test reduces page reads and allocated space without exceeding the agreed CPU and query latency thresholds.

Incorrect Answers

B:

Select an appropriate service tier and compute capacity using observed CPU and workload behavior, with a controlled scale and cost review. That relates to a separate SQL administration problem: A database experiences sustained CPU throttling on an underprovisioned Azure SQL Database but administrators increase storage only. The Brookside Manufacturing requirement is instead: A large rowstore fact table creates I/O pressure because repeated string values are stored uncompressed in cold partitions. That approach does not directly establish the required fix; the requested acceptance evidence is: The compression test reduces page reads and allocated space without exceeding the agreed CPU and query latency thresholds.

C:

Review independent service-tier compute and storage quotas and scale the supported storage setting or tier as required. That relates to a separate SQL administration problem: A managed SQL service's storage approaches its limit and the scaling plan assumes that increasing vCores always increases the allowable data size. The Brookside Manufacturing requirement is instead: A large rowstore fact table creates I/O pressure because repeated string values are stored uncompressed in cold partitions. That approach does not directly establish the required fix; the requested acceptance evidence is: The compression test reduces page reads and allocated space without exceeding the agreed CPU and query latency thresholds.

D:

Reconfigure supported VM storage and I/O placement for data, log and tempdb using measured throughput and latency requirements.

Question 72

At Brookside Manufacturing, the production analytics data team maintains a plant inventory and factory operations database estate with requirements for planned outages and accurate production reporting. The acceptance review requires independent evidence for: A large rowstore fact table creates I/O pressure because repeated string values are stored uncompressed in cold partitions. Which observed result BEST proves the intended problem is corrected?

  1. Compute utilization and billing follow the idle and burst pattern while peak requests meet the stated restart-latency requirement.
  2. A comparable transaction test shows lower sustained disk latency and transaction-log write waits without risking data durability.
  3. The database reports adequate free storage after the approved change and no growth operation fails its service limit.
  4. The compression test reduces page reads and allocated space without exceeding the agreed CPU and query latency thresholds.

Explanation

Correct Answer

D:

The compression test reduces page reads and allocated space without exceeding the agreed CPU and query latency thresholds. That observable result supports resolution of: A large rowstore fact table creates I/O pressure because repeated string values are stored uncompressed in cold partitions. The corresponding corrective change is: Evaluate row or page data compression on suitable tables or partitions and measure CPU versus I/O and storage tradeoffs. The Brookside Manufacturing reviewer can distinguish demonstrated database behavior from an untested change claim.

Incorrect Answers

A:

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 Brookside Manufacturing issue is instead: A large rowstore fact table creates I/O pressure because repeated string values are stored uncompressed in cold partitions. Its decisive acceptance evidence would be: The compression test reduces page reads and allocated space without exceeding the agreed CPU and query latency thresholds.

B:

Question 73

At Brookside Manufacturing, the production analytics data team maintains a plant inventory and factory operations database estate with requirements for planned outages and accurate production reporting. An authorized design review finds: An OLTP database is configured with a service tier selected for analytical reporting but short transactions show persistent log-write contention. Which action BEST resolves this specific database administration problem?

  1. Use service-tier and workload metrics to choose a supported Azure SQL performance configuration appropriate for transactional latency.
  2. Evaluate a compatible serverless compute tier with auto-pause or autoscaling settings and explicitly test connection warm-up behavior.
  3. Choose a partition function and aligned indexes based on the actual date predicate and verify partition elimination in execution plans.
  4. Configure suitable elastic pool size and per-database resource limits based on aggregate and peak usage observations.

Explanation

Correct Answer

A:

Use service-tier and workload metrics to choose a supported Azure SQL performance configuration appropriate for transactional latency. This addresses the specific Azure SQL or SQL Server operational issue: An OLTP database is configured with a service tier selected for analytical reporting but short transactions show persistent log-write contention. The Brookside Manufacturing team should verify the result rather than assume an accepted configuration is sufficient. The decisive acceptance evidence is: Representative write transactions achieve the required log and commit latency after the targeted tier or compute adjustment.

The corresponding corrective change is: Configure suitable elastic pool size and per-database resource limits based on aggregate and peak usage observations. The Westhaven Retail reviewer can distinguish demonstrated database behavior from an untested change claim.

Incorrect Answers

A:

The compression test reduces page reads and allocated space without exceeding the agreed CPU and query latency thresholds. That result is evidence for another corrective change: Evaluate row or page data compression on suitable tables or partitions and measure CPU versus I/O and storage tradeoffs. The alternative problem is: A large rowstore fact table creates I/O pressure because repeated string values are stored uncompressed in cold partitions. The current Westhaven Retail issue is instead: An application requires predictable resource isolation but several databases in one elastic pool consume each other's shared headroom without monitoring. Its decisive acceptance evidence would be: Concurrent load testing shows each database remains within its allocated limit while the pool stays below its saturation threshold.

B:

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 Westhaven Retail issue is instead: An application requires predictable resource isolation but several databases in one elastic pool consume each other's shared headroom without monitoring. Its decisive acceptance evidence would be: Concurrent load testing shows each database remains within its allocated limit while the pool stays below its saturation threshold.

C:

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 Westhaven Retail issue is instead: An application requires predictable resource isolation but several databases in one elastic pool consume each other's shared headroom without monitoring. Its decisive acceptance evidence would be: Concurrent load testing shows each database remains within its allocated limit while the pool stays below its saturation threshold.
