Microsoft DP-800 Practice Test 54
Question 530
A database engineer at Brookfield Labs is investigating this case: A post-deployment seed script runs each release. The relevant finding is: Repeated deploy inserts duplicate config rows. What operational condition would provide the earliest useful regression warning?
- Monitor unique-key errors after releases
- Track drift in reference rows
- Monitor artifact substitution and provenance
- Monitor invalid reference artifacts
Explanation
Correct Answer
A:
Repeated deploy inserts duplicate config rows. Monitor unique-key errors after releases.
Incorrect Answers
B:
“Track drift in reference rows” addresses the sql project static reference data situation—manual environment setup produces different status values. The observed failure is: Repeated deploy inserts duplicate config rows. Monitor unique-key errors after releases.
C:
“Monitor artifact substitution and provenance” concerns Untracked edits cause staging and production mismatch; the reported problem instead is Repeated deploy inserts duplicate config rows. Monitor unique-key errors after releases.
D:
“Monitor invalid reference artifacts” concerns Build fails because external objects cannot be resolved; the reported problem instead is Repeated deploy inserts duplicate config rows. Monitor unique-key errors after releases.
Question 531
Cascade Manufacturing is responsible for an Azure SQL or Microsoft SQL workload. A production schema change is triggered immediately on commit. Operational evidence: No manual signoff for a high-risk migration. What initial check best narrows the technical cause without altering business data?
- Inspect procedure contract and representative test matrix
- Inspect pipeline identity, secret store and service principal scope
- Inspect stable lookup identifiers and change policy
- Inspect pipeline environments and approvals
Explanation
Correct Answer
D:
No manual signoff for a high-risk migration. Inspect pipeline environments and approvals.
Incorrect Answers
A:
“Inspect procedure contract and representative test matrix” concerns Developer has no repeatable tests for edge-case tax data; the reported problem instead is No manual signoff for a high-risk migration. Inspect pipeline environments and approvals.
B:
“Inspect pipeline identity, secret store and service principal scope” concerns Build logs may expose credential values; the reported problem instead is No manual signoff for a high-risk migration. Inspect pipeline environments and approvals.
C:
“Inspect stable lookup identifiers and change policy” concerns Manual environment setup produces different status values; the reported problem instead is No manual signoff for a high-risk migration. Inspect pipeline environments and approvals.

Question 535
At Seabrook University, a production schema change is triggered immediately on commit. The observed constraint is: No manual signoff for a high-risk migration. What operational condition would provide the earliest useful regression warning?
- Monitor deployment authorization and emergency bypass use
- Monitor repeat untracked emergency DDL
- Monitor bypass permissions and failed approvals
- Monitor deployment health and rollback triggers
Explanation
Correct Answer
A:
No manual signoff for a high-risk migration. Monitor deployment authorization and emergency bypass use.
Incorrect Answers
B:
“Monitor repeat untracked emergency DDL” concerns Git schema is now older than deployed state; the reported problem instead is No manual signoff for a high-risk migration. Monitor deployment authorization and emergency bypass use.
C:
“Monitor bypass permissions and failed approvals” concerns One maintainer could merge destructive DDL without oversight; the reported problem instead is No manual signoff for a high-risk migration. Monitor deployment authorization and emergency bypass use.
D:
“Monitor deployment health and rollback triggers” concerns Schema build alone does not cover runtime permissions; the reported problem instead is No manual signoff for a high-risk migration. Monitor deployment authorization and emergency bypass use.

Explanation
Correct Answer
A:
Git schema is now older than deployed state. Backport verified change into source and reconcile DACPAC model.
Incorrect Answers
B:
“Build once, sign or checksum the DACPAC and promote same artifact” concerns Untracked edits cause staging and production mismatch; the reported problem instead is Git schema is now older than deployed state. Backport verified change into source and reconcile DACPAC model.
C:
“Create SDK-style SQL Database Project with declarative schema in source control” concerns Broken object dependencies are found only at deployment; the reported problem instead is Git schema is now older than deployed state. Backport verified change into source and reconcile DACPAC model.

Question 538
At Willow Creek Finance, a DBA hotfixes production procedure during an outage. The observed constraint is: Git schema is now older than deployed state. After merging the production hotfix into the version-controlled SQL project, which isolated pilot verifies that the updated project builds and passes representative regression tests?
- Create a sample sqlproj and intentionally introduce an unresolved reference
- Build test project that includes hotfix with regression cases
- Alter a mock database outside the project and perform model comparison
- Build/test against a fixture reference DACPAC
Explanation
Correct Answer
B:
Git schema is now older than deployed state. Build test project that includes hotfix with regression cases.
Incorrect Answers
A:
“Create a sample sqlproj and intentionally introduce an unresolved reference” addresses the sdk-style sql database project situation—broken object dependencies are found only at deployment. The observed failure is: Git schema is now older than deployed state. Build test project that includes hotfix with regression cases.
C:
Comparing a mock out-of-project alteration against a database model is useful for detecting drift, but it does not prove the merged hotfix builds and passes regression tests. The stated pilot is about validating the corrected source project; B exercises that path.
D:
“Build/test against a fixture reference DACPAC” concerns Build fails because external objects cannot be resolved; the reported problem instead is Git schema is now older than deployed state. Build test project that includes hotfix with regression cases.
Question 539

- Future publish does not silently revert required fix
- End-to-end call succeeds with expected permissions
Explanation
Correct Answer
C:
Git schema is now older than deployed state. Future publish does not silently revert required fix.
Incorrect Answers
A:
“All required invariants pass before merge” concerns Developer has no repeatable tests for edge-case tax data; the reported problem instead is Git schema is now older than deployed state. Future publish does not silently revert required fix.
B:
“Resulting model has one intentional supported column definition” concerns Merge creates inconsistent schema model; the reported problem instead is Git schema is now older than deployed state. Future publish does not silently revert required fix.
D:
“End-to-end call succeeds with expected permissions” concerns Schema build alone does not cover runtime permissions; the reported problem instead is Git schema is now older than deployed state. Future publish does not silently revert required fix.
