Quick Answer
The answer is the data classification policy. This document is the authoritative source for defining classification levels—such as public, internal, confidential, and restricted—and the specific handling procedures for each category, including personally identifiable information (PII). In data governance best practices, the data classification policy establishes the rules for labeling, storing, transmitting, and disposing of sensitive data, making it the correct choice over a data dictionary, which only describes metadata and schema. On the CompTIA Data+ DA0-001 exam, this question tests your understanding of governance documentation roles; a common trap is confusing the data classification policy with a data dictionary or privacy policy. Remember the memory tip: “Classify the data, not the dictionary”—if it involves levels and handling rules, it’s the classification policy.
This DA0-001 practice question tests your understanding of comparing and contrasting data concepts. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A data governance team is drafting a policy for handling personally identifiable information (PII). According to data governance best practices, which document should define the classification levels and handling procedures?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Data dictionary
Why wrong: A data dictionary defines metadata for data elements, not handling procedures.
Data classification policy
A data classification policy categorizes data by sensitivity and outlines handling rules.
Data quality report
Why wrong: A data quality report assesses quality dimensions, not classification.
Data flow diagram
Why wrong: A data flow diagram illustrates how data moves through systems.

Correct answer & explanation
Data classification policy
The data classification policy is the authoritative document that defines classification levels (e.g., public, internal, confidential, restricted) and specifies handling procedures for each category, including PII. This aligns with data governance best practices, as it establishes the rules for labeling, storing, transmitting, and disposing of sensitive data. A data dictionary describes metadata and schema, not classification rules.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

Data dictionary
Why it's wrong here
A data dictionary defines metadata for data elements, not handling procedures.
Data classification policy
Why this is correct
A data classification policy categorizes data by sensitivity and outlines handling rules.

Common exam traps
The trap here is that candidates confuse the data dictionary (which describes data structure) with the data classification policy (which governs data sensitivity and handling), leading them to select the dictionary as the document that defines classification levels.
Detailed technical explanation
Under the hood, a data classification policy typically references standards like ISO/IEC 27001 or NIST SP 800-53 to assign labels (e.g., 'Confidential' for PII) and mandates controls such as encryption at rest (AES-256) and in transit (TLS 1.2+). In a real-world scenario, a healthcare organization would use its classification policy to require that patient records (PII) be stored in encrypted databases with role-based access, while a data dictionary would only list the column 'patient_ssn' as a VARCHAR(11).
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the DA0-001 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
