Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Single version of truth
Why this is correct
Consolidating departmental spreadsheets into one reporting layer establishes a single version of truth: every consumer queries the same governed data rather than reconciling divergent copies. This removes conflicting figures and supports consistent, auditable reporting across the organisation.
- ✗
Data dictionary
Why it's wrong here
A data dictionary documents definitions, owners and formats for individual fields; it does not itself centralise reporting or replace departmental spreadsheets. It would be correct when standardising terminology across systems, whereas the stem describes consolidating reporting into one governed layer.
- ✗
Data lineage
Why it's wrong here
Data lineage traces the origin and transformation path of data through pipelines; it does not consolidate reporting or replace departmental spreadsheets. It would be correct when auditing how a figure was derived, not when establishing a single governed reporting layer.
- ✗
Row-level security
Why it's wrong here
Row-level security filters which records a user can query within a dataset; it does not create a centralised reporting layer or eliminate spreadsheet duplication. It would be correct when restricting regional managers to their own territory's data inside a shared report.
