Exam AI-102 topic 2 question 6 discussion

Based on the subscription, I think, it could also be Yes Yes Yes "Free-tier subscription quota: 1,000 person groups. Each holds up to 1,000 persons. S0-tier subscription quota: 1,000,000 person groups. Each holds up to 10,000 persons." https://docs.microsoft.com/en-us/rest/api/faceapi/person-group/create?tabs=HTTP

Yes No Yes "Free-tier subscription quota: 1,000 person groups. Each holds up to 1,000 persons. So in the code you can have 1000 person groups and 1000 persons each giving you 1,000,000 people

ChatGPT Response: 1. The code will add a face image to a person object in a person group: Yes: In the Face API, adding a face to a person object in a person group is a typical operation. You use the add_face method (or similar method depending on the SDK or API) to associate a face with a person object within a specific person group. 2. The code will work for up to 10,000 people: Yes: Azure Face API can typically support up to 10,000 people in a person group. This is a documented limit for the Face API's person groups, so the code can handle this number of people. 3. add_face can be called multiple times to add multiple face images to a person object: Yes: You can call the add_face method multiple times to associate multiple face images with a single person object. This helps improve the accuracy of face recognition by allowing the system to recognize the same person from different angles or lighting conditions.

Another of those ambigous guessing game from the dysfunctional microsoft. I will answer the second one No. Just assuming the question creator is asking whether one person group can have 10K persons. Otherwise I hope he/she would have given the plan. I do not understand the point of all these questions and remembering these useless facts.

Second should be yes .Link => https://learn.microsoft.com/en-us/rest/api/face/person-group-operations/create-person-group?view=rest-face-v1.1-preview.1&tabs=HTTP.. It will be supported by Free tier subscription quota.

Yes No Yes

The correct sequence for this problem solution is Yes No Yes.

Yes No Yes

Yes No Yes

The code you’ve provided is intended to add a face image to a person object in a person group using the Azure Face API, so: Yes, the code will add a face image to a person object in a person group, provided the code is corrected for syntax errors and proper API usage. Yes, the code can work for up to 10,000 people, as long as the Azure Face API limits are adhered to and the appropriate subscription tier is used. Yes, the add_face function can be called multiple times to add multiple face images to a person object, subject to the limits imposed by the Azure Face API.

Images sent to the service are not stored after analysis. https://learn.microsoft.com/en-us/legal/cognitive-services/face/data-privacy-security

Is this a trick question? From here: https://westus.dev.cognitive.microsoft.com/docs/services/563879b61984550e40cbbe8d/operations/563879b61984550f3039523b No image will be stored. Only the extracted face feature(s) will be stored on server until PersonGroup PersonFace - Delete, PersonGroup Person - Delete or PersonGroup - Delete is called.

Yes No - As the code will keep working in other groups (for instance), and as AzureJobsTillRetire says, a statement that's not generally true is false No - As the image is not really 'added', just their features "No image will be stored. Only the extracted face feature will be stored on server until PersonGroup PersonFace - Delete, PersonGroup Person - Delete or PersonGroup - Delete is called." --see: https://learn.microsoft.com/en-us/rest/api/faceapi/person-group/create?view=rest-faceapi-v1.0&tabs=HTTP The way it works, you have to update a face https://learn.microsoft.com/en-us/rest/api/faceapi/person-group-person/update-face?view=rest-faceapi-v1.0&tabs=HTTP. If you register a new pic for an existing user it will just create a new one and return a new persistedFaceId.

You can vary the person group id and the person id while making the call, so even with the free tier is still way above the mention 10,000 people limitation. The only limitation that is defined for this API is this Response 403 Persisted face number reached limit, maximum is 248 per person. Link here: https://westus.dev.cognitive.microsoft.com/docs/services/563879b61984550e40cbbe8d/operations/563879b61984550f3039523b

Once you have the Person ID from the Create Person call, you can add up to 248 face images to a Person per recognition model. They are all true, the limit is 75 milion persons per group
