Question 460

At Seabrook University, a SQL workload under snapshot isolation sees update conflicts. The observed constraint is: App treats concurrency conflict as permanent failure. What operational condition would provide the earliest useful regression warning?

  1. Monitor index usage and storage overhead
  2. Monitor retry storms and repeat conflicts
  3. Monitor plan forcing and parameter regression
  4. Monitor Query Store regressed queries

Explanation

Correct Answer

B:

App treats concurrency conflict as permanent failure. Monitor retry storms and repeat conflicts.

Incorrect Answers

A:

“Monitor index usage and storage overhead” concerns A single recommendation ignores write/storage cost; the reported problem instead is App treats concurrency conflict as permanent failure. Monitor retry storms and repeat conflicts.

C:

“Monitor plan forcing and parameter regression” concerns The cached query plan favors one selectivity pattern; the reported problem instead is App treats concurrency conflict as permanent failure. Monitor retry storms and repeat conflicts.

D:

“Monitor Query Store regressed queries” concerns Query Store captures a new high-cost plan; the reported problem instead is App treats concurrency conflict as permanent failure. Monitor retry storms and repeat conflicts.

Question 461

A database engineer at Atlas Publishing is investigating this case: A team stores loose .sql files with no build validation. The relevant finding is: Broken object dependencies are found only at deployment. What initial check best narrows the technical cause without altering business data?

  1. Inspect project references and deployment variables
  2. Compare deployed schema model with project baseline
  3. Inspect SQL project model and compatible build tooling
  4. Inspect build artifact hash and promotion process

Explanation

Correct Answer

C:

Broken object dependencies are found only at deployment. Inspect SQL project model and compatible build tooling.

Incorrect Answers

A:

“Inspect project references and deployment variables” concerns Build fails because external objects cannot be resolved; the reported problem instead is Broken object dependencies are found only at deployment. Inspect SQL project model and compatible build tooling.

B:

“Compare deployed schema model with project baseline” concerns Future deployment would overwrite or conflict with unknown change; the reported problem instead is Broken object dependencies are found only at deployment. Inspect SQL project model and compatible build tooling.

D:

“Inspect build artifact hash and promotion process” concerns Untracked edits cause staging and production mismatch; the reported problem instead is Broken object dependencies are found only at deployment. Inspect SQL project model and compatible build tooling.

Question 462

Mountainview Realty is responsible for an Azure SQL or Microsoft SQL workload. A team stores loose .sql files with no build validation. Operational evidence: Broken object dependencies are found only at deployment. Which proposed change is the most suitable response to the observed constraint?

  3. Create SDK-style SQL Database Project with declarative schema in source control
  4. Detect and review schema drift before applying declarative changes

Explanation

Correct Answer

C:

Broken object dependencies are found only at deployment. Create SDK-style SQL Database Project with declarative schema in source control.

Create SDK-style SQL Database Project with declarative schema in source control.

D:

“Detect and review schema drift before applying declarative changes” concerns Future deployment would overwrite or conflict with unknown change; the reported problem instead is Broken object dependencies are found only at deployment. Create SDK-style SQL Database Project with declarative schema in source control.

Question 463

At Willow Creek Finance, a team stores loose .sql files with no build validation. The observed constraint is: Broken object dependencies are found only at deployment. What isolated pilot would provide the strongest evidence before rollout?

Explanation

Correct Answer

C:

Broken object dependencies are found only at deployment. Build a sample sqlproj and intentionally introduce an unresolved reference.

Incorrect Answers

A:

“Alter a mock database outside the project and perform model comparison” concerns Future deployment would overwrite or conflict with unknown change; the reported problem instead is Broken object dependencies are found only at deployment. Build a sample sqlproj and intentionally introduce an unresolved reference.

B:

D:

“Build/test against a fixture reference DACPAC” concerns Build fails because external objects cannot be resolved; the reported problem instead is Broken object dependencies are found only at deployment. Build a sample sqlproj and intentionally introduce an unresolved reference.

Question 464

A database engineer at Granite Ridge Technology is investigating this case: A team stores loose .sql files with no build validation. The relevant finding is: Broken object dependencies are found only at deployment. Which acceptance result most directly demonstrates the requirement has been satisfied?

  1. Mixed-version applications function through release window
  2. Build detects invalid references before production release
  3. External name resolves without hard-coding production names
  4. Production stage awaits authorized signoff

Explanation

Correct Answer

B:

Broken object dependencies are found only at deployment. Build detects invalid references before production release.

Incorrect Answers

A:

“Mixed-version applications function through release window” concerns Old application version still queries the previous name; the reported problem instead is Broken object dependencies are found only at deployment. Build detects invalid references before production release.

C:

“External name resolves without hard-coding production names” concerns Build fails because external objects cannot be resolved; the reported problem instead is Broken object dependencies are found only at deployment. Build detects invalid references before production release.

D:

“Production stage awaits authorized signoff” concerns No manual signoff for a high-risk migration; the reported problem instead is Broken object dependencies are found only at deployment. Build detects invalid references before production release.

Question 465

  3. Monitor invalid reference artifacts
  4. Monitor build validation and tooling versions

Explanation

Correct Answer

D:

Broken object dependencies are found only at deployment. Monitor build validation and tooling versions.

Incorrect Answers

A:

“Monitor drift in reference rows” concerns Manual environment setup produces different status values; the reported problem instead is Broken object dependencies are found only at deployment. Monitor build validation and tooling versions.

B:

“Monitor unauthorized DDL outside pipeline” concerns Future deployment would overwrite or conflict with unknown change; the reported problem instead is Broken object dependencies are found only at deployment. Monitor build validation and tooling versions.

C:
