The answer is assessing the types of personal data processed and the risks to data subjects, as this is the core priority of a GDPR Data Protection Impact Assessment (DPIA). Under GDPR Article 35, a DPIA is mandatory when processing is likely to result in high risk to individuals, and it must systematically evaluate the nature, scope, context, and purposes of processing, along with the necessity and proportionality of the data handling, to identify and mitigate risks to data subjects’ rights and freedoms. On the CompTIA SecurityX CAS-004 exam, this concept tests your understanding of privacy by design and the DPIA as a risk management tool, often appearing in scenario-based questions where you must distinguish between operational tasks (like data encryption) and the foundational assessment of data types and risks. A common trap is focusing on technical controls first, but the DPIA’s priority is always the systematic risk analysis of personal data processing. Remember the mnemonic “DPIA = Data, Purpose, Impact, Assessment” to recall that identifying the data types and their risks comes before any mitigation steps.
CAS-004 Governance, Risk and Compliance Practice Question
This CAS-004 practice question tests your understanding of governance, risk and compliance. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 company is implementing a new cloud-based SaaS application and needs to ensure compliance with GDPR. The security team is tasked with updating the data protection impact assessment (DPIA). Which of the following should the team prioritize?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Assessing the types of personal data processed and the risks to data subjects
Under GDPR, a Data Protection Impact Assessment (DPIA) is mandatory when processing personal data that is likely to result in high risk to individuals. The core requirement is to systematically assess the types of personal data being processed, the necessity and proportionality of the processing, and the risks to data subjects' rights and freedoms. This directly aligns with option A, as the DPIA must identify and mitigate privacy risks before the SaaS application goes live.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Assessing the types of personal data processed and the risks to data subjects
Why this is correct
DPIA focuses on the processing of personal data and associated risks.
Related concept
Read the scenario before looking for a memorised answer.
✗
Defining data retention schedules for all data types
Why it's wrong here
Retention schedules are part of data governance, not specifically DPIA.
✗
Conducting a vulnerability scan of the SaaS application
Why it's wrong here
Vulnerability scanning is a technical control, not a DPIA.
✗
Reviewing the cloud provider's SLA for uptime guarantees
Why it's wrong here
SLA review is operational, not a DPIA requirement.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse a DPIA with a security assessment (like a vulnerability scan or SLA review), but the DPIA is specifically a privacy risk assessment mandated by GDPR Article 35, not a general security or operational review.
Detailed technical explanation
How to think about this question
A DPIA under GDPR Article 35 must include a systematic description of processing operations, an assessment of necessity and proportionality, and an evaluation of risks to data subjects' rights. The risk assessment uses a likelihood-severity matrix, considering factors like data sensitivity (e.g., special categories under Article 9), scale of processing, and potential for discrimination or identity theft. In practice, the DPIA must be updated before any significant change in processing, such as migrating to a new SaaS platform, and failure to conduct one can result in fines up to 10 million EUR or 2% of global annual turnover.

→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the CAS-004 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.
