You are tasked to use Face API in your application to search for a face of a person in a given set of photographs within a specified internal threshold. Since the set of pictures is large, you decide to use a large face list to persist face ids. This also meets your requirement that the ids will not expire. Given the scenario, review the code snippet given below and complete it by selecting correct answer choices. (choose two answers) 
<pre class="brush:java;">POST https://{endpoint}/face/v1.0/……………………………………
{
"faceId": "d9c26a66-6834-3331-9f5d-978d456g75426",
"largeFaceListId": "largeFaceListID1",
"maxNumOfCandidatesReturned": 8,
"mode": "..............................................."
}
</pre> 

Answer options:

A.detect
B.findsimilars
C.matchPerson
D.matchFace
E.identify

Correct Answers: B and C 
Here is the completed JSON code 
<pre class="brush:java;">POST https://{endpoint}/face/v1.0/findsimilars
{
"faceId": "d9c26a66-6834-3331-9f5d-978d456g75426",
"largeFaceListId": "largeFaceListID1",
"maxNumOfCandidatesReturned": 8,
"mode": “matchPerson”
}
</pre>Option A is incorrect because the detect function is used to identify rectangular coordinates of a face. It provides the identifier for the face that will be used for identification, finding a similar face or verification of a face.
Option B is correct because the requirement is to find similar faces.
Option C is correct because the requirement is to find a known person in a given set of photographs. matchperson is the correct mode of findsimilars API for this scenario.
Option D is incorrect because matchFace ignores the internal threshold and finds faces where the similarity is even low.
Option E is incorrect because the identify function is used for finding closest matches to a person group or large person group. However, the requirement here is to use a large group list.
