Exam AWS Certified Developer Associate topic 1 question 36 discussion

D: Do you have a Usage Plan? if not need to create one. Link you API with Usage Plan. For that add a stage, it will link your API. Do you have API Key? if not you need to create an API Key and enable it. Add the Usage Plan which is linked with your API to this API Key. For that add Usage Plan.

Ans: D https://stackoverflow.com/questions/39061041/using-an-api-key-in-amazon-api-gateway

A) Eliminated - Redeployment is only needed if you've made changes to the API configuration or code itself (like adding new endpoints, changing logic, etc.). In this case, the issue is not with the API's deployment or its functionality. The registration page and the API key creation process are already working (users are signing up and receiving keys).

D is the correct one. "The createUsagePlanKey method must be called to associate the newly created API key with the correct usage plan"

To grant access to the API for newly registered users, the developer needs to associate the newly created API key with the API usage plan. To do this, the createUsagePlanKey method should be called to add the API key to the correct usage plan. By default, API Gateway only grants access to API keys that are associated with a usage plan, and new API keys are not automatically associated with a usage plan. The usage plan specifies the throttling and quota limits for the API. Once the API key is added to the usage plan, the user should be able to access the API.

Answer is D.

The most likely issue is that the new API key has not been associated with an appropriate usage plan. The usage plan specifies the API stages and throttling limits that apply to the API key. The 403 Forbidden error is returned when an API key is not associated with a usage plan that allows access to the requested API method. To grant access to the new users, the createUsagePlanKey method should be called to associate the newly created API key with the appropriate usage plan. The usage plan must exist before the API key can be associated with it. Therefore, option D is the correct answer.

DDDDDD

Correct is D

Answer - D

Import and create are either or operations according to this: https://docs.aws.amazon.com/apigateway/latest/developerguide/api-gateway-setup-api-key-with-restapi.html So you either create or import, not both, so I agree with D.

Answer is D: 403 - Forbidden – The request is not allowed or the instance metadata service is turned off. When you associate a usage plan with an API and enable API keys on API methods, every incoming request to the API must contain an API key. API Gateway reads the key and compares it against the keys in the usage plan. If there is a match, API Gateway throttles the requests according to the plan's request limit and quota. Otherwise, it throws an InvalidKeyParameter exception. As a result, the caller receives a 403 Forbidden response.

ApiKey is already created and available, no need of ImportApiKey (It's either CreateApiKey or ImportApiKey) So, CreateUsagePlan will link the ApiKey to API and give users access. Answer :D https://docs.aws.amazon.com/apigateway/latest/developerguide/api-gateway-api-usage-plans.html

Answer: D

Ans : D

Correct answer is D ! A usage plan specifies who can access one or more deployed API stages and methods—and also how much and how fast they can access them. The plan uses API keys to identify API clients and meters access to the associated API stages for each key. It also lets you configure throttling limits and quota limits that are enforced on individual client API keys.

C,D are correct but I think C should be first priority . https://docs.aws.amazon.com/apigateway/latest/developerguide/api-gateway-setup-api-key-with-console.html
