DA0-002 Visualization and Reporting Practice Question
A company is implementing a centralized reporting layer to replace departmental spreadsheets. Which TWO benefits are most directly achieved?
⚠ Common exam trap
The trap is selecting benefits that sound plausible but are either impossible (elimination of all errors) or not direct outcomes (faster report generation).
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Improved data lineage
Option A (Improved data lineage) is correct because a centralized reporting layer consolidates data from multiple sources into a governed pipeline, making it possible to trace data from its origin through transformations to the final report, which departmental spreadsheets cannot provide. Option C (Single version of truth) is correct because centralizing reporting ensures all departments consume the same curated, consistent data set rather than maintaining divergent spreadsheet copies, eliminating conflicting figures across the organization. Option B is incorrect because centralization reduces but cannot eliminate all data errors, which can still arise from source entry mistakes or transformation logic. Option D is incorrect because centralization typically increases, not reduces, the need for data governance to define ownership, quality rules, and access controls. Option E is incorrect because faster report generation is not a guaranteed direct benefit; performance depends on architecture, query design, and infrastructure, and centralization can even add latency through ETL processes.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Improved data lineage
Why this is correct
A centralized reporting layer applies consistent transformations and documented source-to-target mappings, so every figure can be traced from report back to originating system. This satisfies the requirement to replace departmental spreadsheets, whose manual extracts break the chain of lineage.
- ✗
Elimination of all data errors
Why it's wrong here
No reporting layer eliminates every data error; centralisation reduces duplication and inconsistent definitions but cannot prevent source-entry mistakes or transformation faults. It is tempting because removing spreadsheets removes many manual transcription errors, and error elimination would be correct only for a narrowly scoped validation rule at the point of entry.
- ✓
Single version of truth
Why this is correct
Centralising reporting means all departments query the same governed datasets and metric definitions, eliminating conflicting spreadsheet figures. This satisfies the requirement to replace departmental spreadsheets, where each team maintains its own version and reconciliation becomes manual and error-prone.
- ✗
Reduced need for data governance
Why it's wrong here
A centralised reporting layer increases the need for data governance, since shared definitions, ownership and quality rules must be agreed across departments. It is tempting because consolidation removes some duplicated spreadsheet maintenance, and reduced governance effort would be correct only where a single team already owns all data end to end.
- ✗
Faster report generation
Why it's wrong here
Centralisation removes manual spreadsheet collation but does not inherently accelerate query or rendering performance; speed depends on warehouse design, modelling and infrastructure. It is tempting because consolidated data feels quicker to access, and faster generation would be the correct benefit when the bottleneck is repeated manual extraction rather than the reporting layer itself.
