Sprint 01 — Diagnostic Answer Key
1 — C. Data Governance first
Why: the unresolved issue is authoritative business meaning/decision rights. Integration implements the approved definition; it should not invent authority.
A: developer efficiency is not business authority.
B: defect count does not determine official meaning.
C: correct—Governance decides; Management implements.
D: publishing conflicting definitions preserves the governance failure.
Source: Governance vs Management.
2 — A. Logical Data Model
Why: the logical model provides detailed entities/attributes/relationships independent of DBMS-specific physical implementation.
B: physical model is implementation-specific.
C: metamodel describes Metadata objects/types.
D: catalog supports discovery/location.
Source: Chapter 5 modeling distinctions.
3 — D. Data Lineage
Why: origin + movement/transformation + downstream use is lineage.
A: glossary supplies business meaning.
B: dictionary supplies element structure.
C: catalog discovery helps find assets but does not by itself answer transformation path.
D: correct.
Source: Chapter 12 Metadata.
4 — B. Accuracy
Why: the value conforms to rules but does not represent the real customer correctly.
A: validity asks whether the value is allowed/formatted correctly; those tests pass.
B: correct—truth/reality is wrong.
C: the value is present.
D: no age/freshness issue is given.
Source: Validity vs Accuracy.
5 — A. Master Data Management
Why: persistent entity identity and source-to-enterprise ID mappings are MDM problems.
B: RDM controls classification/value domains.
C: cataloging does not resolve identity.
D: a warehouse can consume trusted identity but should not substitute for MDM logic.
Source: Reference vs Master.
6 — C. Conformed Dimension
Why: a conformed dimension gives separate fact areas the same governed descriptive meaning.
A: not the deciding concept.
B: staging prepares loads.
C: correct—shared governed Product meaning across marts.
D: ODS is current/near-current integrated storage, not dimensional conformance.
Source: Fact vs Dimension vs Conformed Dimension.
7 — B. Transition-state Architecture
Why: coexistence, synchronization, migration waves and retirement between current and target are transition-state concerns.
A: current state alone does not describe the migration bridge.
B: correct.
C: physical model describes implementation structure, not enterprise migration state.
D: glossary manages business terms.
Source: Chapter 4 Architecture.
8 — D. Authorization / entitlement design
Why: identity proof succeeded; the failure is that the authenticated identity has excessive permissions/exposure.
A: authentication already worked.
B: encryption does not decide which authenticated user is entitled to which fields.
C: availability is not the issue.
D: correct.
Source: Chapter 7 Security.
9 — C. Change Data Capture
Why: the management question is “which rows changed?” and transmit those deltas.
A: replication’s objective is maintaining a synchronized copy, even though it may use change logs.
B: virtualization exposes data without the same change-event objective.
C: correct.
D: CEP interprets combinations/patterns of events rather than simply identifying source-row changes.
Source: Chapter 8 Deep Card B.
10 — A. CAP
Why: CAP describes distributed-system trade-offs among consistency, availability and partition tolerance when a partition occurs.
A: correct.
B: ACID is a transaction-property model.
C: BASE is an availability/eventual-consistency posture, not the named partition trade-off framework.
D: RACI is a responsibility-assignment model.
Source: Chapter 6 Deep Card D.
Sprint analysis
Record: - score / 10; - total time; - questions >75 sec; - confidence-5 misses; - lookup attempts and whether they changed outcome; - changed answers and whether the change helped; - error tags.
Interpretation
- 8–10 correct and within time: pacing foundation is viable; inspect error quality before adding volume.
- 8–10 correct but slow: keep concepts, train faster discrimination/lookup triage.
- ≤7 correct: diagnose knowledge/confusion errors before treating speed as the main problem.
These thresholds are an internal practice heuristic, not an official DAMA scoring rule.
