B. No Explanation: The given solution does not meet the goal. Deleting 1,000 entries from the PersonGroup object for Ben Smith will not make room for additional entries because the limit for a PersonGroup in the Face API is 10,000 entries. Even if you delete some entries, the PersonGroup will still be at its maximum capacity.

It is "No" because Person group can only hold up to 10000 persons. To hold more than this , we would need to create a LargePersonGroup, which holds up to 1000000 people. https://docs.microsoft.com/en-us/rest/api/faceapi/persongroup

It's possible to delete faces entries for a person. However the question states "The solution must ensure that Ben Smith can be identified by all the entries." This seems like you need to keep the others so moving to a LargePersonGroup is required to keep the existing 10k. If you think it doesn't require keeping the 10k and just making space for new entries the answer is Yes. DELETE {Endpoint}/face/v1.0/persongroups/{personGroupId}/persons/{personId}/persistedfaces/{persistedFaceId}
