CAS-004 Governance, Risk, and Compliance Practice Question
Under GDPR, which of the following is a data subject right that allows an individual to request that their personal data be erased?
⚠ Common exam trap
CAS-005 often tests the confusion among GDPR data subject rights, particularly mixing up erasure with portability or rectification, by using similar-sounding descriptions.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Right to erasure
The right to erasure (also known as the 'right to be forgotten') is explicitly defined in GDPR Article 17, allowing data subjects to request deletion of their personal data under certain conditions. This is a core data subject right alongside access, rectification, and portability. Option C directly names this right.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Right to portability
Why it's wrong here
Portability lets a data subject receive their data in a structured, machine-readable format and transmit it elsewhere, not erase it. It is tempting because it concerns the subject's control over data, but erasure is the right to erasure under Article 17.
- ✗
Right to access
Why it's wrong here
The right of access lets a data subject obtain confirmation and a copy of their personal data, not demand deletion. It is tempting because it is a core GDPR right, but erasure is the separate right to erasure under Article 17.
- ✓
Right to erasure
Why this is correct
The right to erasure, or right to be forgotten, lets a data subject demand deletion of personal data where no overriding legal ground for retention applies. This directly satisfies the GDPR requirement for an individual to request erasure of their data.
- ✗
Right to rectification
Why it's wrong here
Rectification lets a data subject correct inaccurate personal data, not erase it. It is tempting because both are GDPR data subject rights over personal data, but erasure is specifically the right to erasure (right to be forgotten) under Article 17.
