Exam AI-102 topic 1 question 5 discussion

I think answer is correct. PUT: puts a file or resource at a specific URI, and exactly at that URI. If there's already a file or resource at that URI, PUT replaces that file or resource. If there is no file or resource there, PUT creates one. POST: POST sends data to a specific URI and expects the resource at that URI to handle the request.

Although in Web Programming, and API dev, PUT is an http(s) request method for an update operation. I can however create a resource when there is no resource to update. I don't know why precisely but the method used by Azure to actually make a REST API request to create a resource is actually "PUT". So, the answers are correct. See Ref: https://docs.microsoft.com/en-us/rest/api/resources/resources/create-or-update

As by zellck 1. PUT 2. CognitiveServices https://learn.microsoft.com/en-us/rest/api/resources/resources/create-or-update

The answer is PUT congnitiveservices Why PUT? Because while POST can also create new resources like PUT but its not idempotent like PUT hence its always better to us PUT when creating services.

PUT and CognitiveSearvices

Cognitive Services are "AI parts" that mimic human cognition (Cognitive) and are immediately available as WebAPI. Embedded applications can build cognitive solutions for vision, speech, language, decision making, and search without the need for technical knowledge in AI or data science.

When i differed with ChatGPT about PUT being correct, this is what I got When creating a new resource in Azure, the PUT method is used to update or create the resource with the provided configuration. In the case of Azure Cognitive Services, you typically use the PUT method to provision a new instance of the service with the specified settings. Therefore, the correct HTTP request to create the new resource should use the PUT method, not POST.

Answer from ChatGPT, PUT and cognitiveservices curl -X PUT -H "Authorization: Bearer {access_token}" -H "Content-Type: application/json" \ -d '{"kind":"TextAnalytics","sku":{"name":"F0"}}' \ "https://management.azure.com/subscriptions/{subscription_id}/resourceGroups/{resource_group_name}/providers/Microsoft.CognitiveServices/accounts/{api_name}?api-version=2021-04-30"

The given answers are CORRECT

PUT is correct. https://learn.microsoft.com/en-us/rest/api/resources/resources/create-or-update

Yes, PUT https://learn.microsoft.com/en-us/rest/api/cognitiveservices/accountmanagement/accounts/create?tabs=HTTP

1. PUT 2. CognitiveServices

1. PUT 2. CognitiveServices https://learn.microsoft.com/en-us/rest/api/resources/resources/create-or-update https://learn.microsoft.com/en-us/azure/cognitive-services/cognitive-services-apis-create-account?tabs=multiservice%2Canomaly-detector%2Clanguage-service%2Ccomputer-vision%2Cwindows#types-of-cognitive-services-resources You can access Azure Cognitive Services through two different resources: A multi-service resource, or a single-service one. - Multi-service resource: Access multiple Azure Cognitive Services with a single key and endpoint. Consolidates billing from the services you use.

PUT CognativeServices

PATCH is eliminated (It is only used for update). I think we can use both POST and PUT (to create resources). But good to use PUT (just in case if API has been re-trigerred, So it will not fail. And 2nd answer is "Cognitive services" which provides a lot of models. (So we can use computer vision as well). if we select only computer vision, then we can't use Sentiment analysis and OCR (for which we are trying to create a resource).

May be the reason to use PUT is because , PUT requests must be idempotent. If a client submits the same PUT request multiple times, the results should always be the same (the same resource will be modified with the same values). POST and PATCH requests are not guaranteed to be idempotent.

Shouldn’t the first one be POST? It says it’s a new resource created, not an existing one updated.
