Question 500

A database engineer at BrightPath Studios is investigating this case: A SQL release rebuilds code differently in each environment. The relevant finding is: Untracked edits cause staging and production mismatch. What operational condition would provide the earliest useful regression warning?

  1. Monitor drift in reference rows
  2. Monitor unique-key errors after releases
  3. Monitor invalid reference artifacts
  4. Monitor artifact substitution and provenance

Explanation

Correct Answer

D:

Untracked edits cause staging and production mismatch. Monitor artifact substitution and provenance.

Incorrect Answers

A:

“Monitor drift in reference rows” concerns Manual environment setup produces different status values; the reported problem instead is Untracked edits cause staging and production mismatch. Monitor artifact substitution and provenance.

B:

“Monitor unique-key errors after releases” concerns Repeated deploy inserts duplicate config rows; the reported problem instead is Untracked edits cause staging and production mismatch. Monitor artifact substitution and provenance.

C:

“Monitor invalid reference artifacts” concerns Build fails because external objects cannot be resolved; the reported problem instead is Untracked edits cause staging and production mismatch. Monitor artifact substitution and provenance.

Question 501

Lakeview Services is responsible for an Azure SQL or Microsoft SQL workload. A SQL project references a separate shared Customers database. Operational evidence: Build fails because external objects cannot be resolved. What initial check best narrows the technical cause without altering business data?

  1. Inspect post-deployment app contract and test principal
  2. Inspect project references and deployment variables
  3. Inspect backward compatibility and deployment ordering
  4. Inspect SQL project model and compatible build tooling

Explanation

Correct Answer

B:

Build fails because external objects cannot be resolved. Inspect project references and deployment variables.

Incorrect Answers

A:

“Inspect post-deployment app contract and test principal” concerns Schema build alone does not cover runtime permissions; the reported problem instead is Build fails because external objects cannot be resolved. Inspect project references and deployment variables.

C:

“Inspect backward compatibility and deployment ordering” concerns Old application version still queries the previous name; the reported problem instead is Build fails because external objects cannot be resolved. Inspect project references and deployment variables.

D:

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

Explanation

Correct Answer

A:

Build fails because external objects cannot be resolved. Monitor invalid reference artifacts.

Question 506

A database engineer at Cascade Manufacturing is investigating this case: An automated publish plan proposes dropping an unused-looking table. The relevant finding is: That table still holds historical reports. What initial check best narrows the technical cause without altering business data?
