Quick Answer
The correct answer is to use the Face API Delete operation to remove stored face IDs. This is because Azure Face API stores personal data—such as face IDs—within PersonGroups or FaceLists, and GDPR compliance demands the ability to delete that data on demand. The dedicated Delete operation (e.g., FaceList - Delete Face or PersonGroup Person - Delete) directly removes the stored face ID and its associated facial data, allowing you to enforce a 30-day deletion policy without needing to recreate the entire resource. On the AI-102 exam, this scenario tests your understanding of Azure’s data lifecycle management and GDPR obligations, often appearing as a distractor where candidates might mistakenly think they need to delete the entire Face API resource or regenerate an API key. A common trap is assuming that simply disabling the API or expiring the subscription satisfies GDPR, but the Delete operation is the precise, granular tool required. Memory tip: “Delete the ID, not the resource” — the Face API’s Delete action targets the stored face data itself, not the service instance.
This AI-102 practice question tests your understanding of implement image and video processing solutions. 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 company uses Azure Face API to detect faces in a crowd. They need to comply with GDPR and delete face data after 30 days. What should they implement?
Enable data encryption at rest.
Why wrong: Encryption does not delete data.
Set a retention policy on the Face API resource.
Why wrong: No such policy exists for Face API.
Use the Face API Delete operation to remove stored face IDs.
Explicitly deleting face data meets GDPR requirements.
Recreate the Face API resource every 30 days.
Why wrong: Unnecessary and causes service disruption.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Use the Face API Delete operation to remove stored face IDs.
Option C is correct because the Azure Face API stores face data (e.g., face IDs) in a PersonGroup or FaceList, and GDPR compliance requires the ability to delete personal data on demand. The Face API provides a dedicated Delete operation (e.g., FaceList - Delete Face or PersonGroup Person - Delete) to remove stored face IDs and associated face data, enabling the 30-day deletion requirement without recreating the resource.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Recreate the Face API resource every 30 days.
Why it's wrong here
Unnecessary and causes service disruption.
Common exam traps
The trap here is that candidates confuse data encryption (which protects data at rest) with data lifecycle management (which deletes data), or assume that Azure services have a universal retention policy setting, when in fact Face API requires explicit API calls to delete stored face data.
Detailed technical explanation
The Face API stores face data as persistent face IDs within PersonGroup, PersonGroupPerson, or FaceList containers. The Delete operation sends an HTTP DELETE request to the specific endpoint (e.g., DELETE /facelists/{faceListId}/persistedFaces/{persistedFaceId}) to remove the face data immediately; this is the only way to programmatically enforce a 30-day data lifecycle without manual intervention. In a real-world scenario, you would implement a scheduled job (e.g., Azure Logic Apps or Azure Functions) that runs daily to query and delete face IDs older than 30 days, ensuring GDPR compliance without disrupting the Face API resource itself.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
