CBDA Data Management & Lifecycle 1 — Questions and Answers
Question 1: Which phase of the data lifecycle involves capturing raw data from source systems and ensuring it is stored in a usable format?
- Data archival
- Data ingestion (Correct answer)
- Data retirement
- Data monetization
Correct answer: Data ingestion
Data ingestion is the process of collecting and importing raw data from various source systems into a storage or processing environment.
Question 2: A data steward is primarily responsible for which of the following?
- Writing ETL transformation code
- Ensuring data quality and adherence to data governance policies (Correct answer)
- Designing the physical database schema
- Managing cloud infrastructure costs
Correct answer: Ensuring data quality and adherence to data governance policies
A data steward is accountable for maintaining data quality standards and ensuring data assets conform to established governance policies.
Question 3: What is the primary purpose of a data retention policy?
- To maximize storage utilization at all times
- To define how long data must be kept and when it should be deleted or archived (Correct answer)
- To determine which users can access sensitive data
- To describe the format in which data is stored
Correct answer: To define how long data must be kept and when it should be deleted or archived
A data retention policy specifies the duration for which data must be retained based on legal, regulatory, and business requirements, and outlines when it should be purged or archived.
Question 4: Which concept describes a single, authoritative repository that serves as the definitive source of data for an organization?
- Data lake
- Data mart
- Single source of truth (SSOT) (Correct answer)
- Operational data store
Correct answer: Single source of truth (SSOT)
A single source of truth (SSOT) is the practice of aggregating and structuring data so that every stakeholder uses the same, consistent reference for key business data.
Question 5: In data lifecycle management, what does 'data archival' typically involve?
- Permanently deleting data that is no longer needed
- Moving infrequently accessed data to lower-cost long-term storage while keeping it retrievable (Correct answer)
- Replicating active data to a secondary production environment
- Converting structured data into unstructured formats
Correct answer: Moving infrequently accessed data to lower-cost long-term storage while keeping it retrievable
Data archival moves old or infrequently accessed data to cost-effective storage while preserving it for future retrieval, compliance, or audit purposes.
Question 6: Which of the following best describes master data management (MDM)?
- A process for encrypting sensitive records in a data warehouse
- A discipline that ensures the organization's critical shared data is consistent, accurate, and authoritative across systems (Correct answer)
- A technique for partitioning large tables to improve query performance
- A method for anonymizing personally identifiable information before analysis
Correct answer: A discipline that ensures the organization's critical shared data is consistent, accurate, and authoritative across systems
MDM is a comprehensive method of enabling an enterprise to link all its critical data to one file, called a master file, to provide a common point of reference.
Question 7: Which data lifecycle stage occurs immediately before data retirement or deletion?
- Data creation
- Data usage and analysis
- Data archival (Correct answer)
- Data ingestion
Correct answer: Data archival
Data archival is typically the stage that precedes retirement or permanent deletion, moving data to long-term storage before it is eventually purged.
