CompTIA Data+ (DA0-002)Data Concepts and EnvironmentsHard
A data governance committee is reviewing a new data acquisition process for customer feedback. The process involves collecting free-text comments, which may contain personally identifiable information (PII) such as names or email addresses, as well as sensitive opinions. The committee needs to categorize this data to determine appropriate access controls and retention policies. What is the most critical data characteristic for this categorization?
- AData sensitivity
- BData volume
- CData variety
- DData velocity
Show answer & explanationAnswer & explanation
Correct answer: A. Data sensitivity
Data sensitivity refers to the level of protection required for data, often determined by whether it contains PII, confidential business information, or other regulated content. For customer feedback with PII and sensitive opinions, sensitivity is the paramount characteristic dictating access, security, and retention.
Why the other options are wrong
- B. Data volume refers to the amount of data, which impacts storage and processing but not directly access controls based on content.
- C. Data variety refers to the different forms of data, relevant for storage solutions but not the primary driver for access control based on PII.
- D. Data velocity refers to the speed at which data is generated or processed, impacting real-time requirements but not content-based access.
Data Sensitivity
A characteristic of data that refers to its level of protection required, based on its potential impact if compromised, lost, or mishandled. It determines access controls, encryption, and retention policies.
- Determines security measures and access controls.
- Includes PII, financial data, health records, trade secrets.
- Often categorized into levels (e.g., Public, Internal, Confidential, Restricted).
- Crucial for compliance with regulations (e.g., GDPR, HIPAA).
- Impacts data retention and disposal policies.
Memory trick: Sensitivity dictates Security and Rules.
