Should be pagination

A. PAGINATION https://developer.atlassian.com/server/confluence/pagination-in-the-rest-api/

A is right.

A - Pagination

B and C cannot be the soluction. A (Pagination) is the solution: When a request is made to get a list, it is almost never a good idea to return all resources at once. This is where a pagination mechanism comes into play. There are two popular approaches to pagination: Offset-based pagination Keyset-based pagination, also known as continuation token or cursor pagination (recommended) Jackson Chris; Gooley Jason; Iliesiu Adrian; Malegaonkar Ashutosh.

D is not because: Rate limiting is an essential REST API design method for developers. Rate-limiting techniques are used to increase security, business impact, and efficiency across the board or end to end. Jackson Chris; Gooley Jason; Iliesiu Adrian; Malegaonkar Ashutosh.

Payload limit - if number of requests exceeded than 413 code returned. Rate limiting - if limit of the number of requests exceeded than 429 code returned. Pagination breaks the content on equal parts (based on limit and offset) and returns them 1 by 1. So to my mind Pagination is correct.

Payload limit - if number of requests exceeded than

A is correct. The question says that it is expecting 500+ records and EACH time returns only 25 (records). To me this says it's returning a valid document back to the user with exactly 25 records. If B were correct the API would return nothing or an invalid document. The question says it returns exactly 25 RECORDS. Pagination is the correct answer.

A is the correct answer. https://nordicapis.com/everything-you-need-to-know-about-api-pagination/

I don't think paginatin is correct, because it only displays 25 restults. If pagination was in place it would show all 550+ results, 25 results at a time but thats not whats happening. I think the answer is B Payload Limit

the rate limit is to avoid DOS attacks. So the number of API calls per sec/min etc.. Not the case here. Correct answer is A

With rate limiting you limit the rate of API calls toward the API, while with payload limiting you limit the size of the API request bodies B is correct

D is not correct. Question says "An application calls a REST" --> that means its talking about a single api call. Rate Limiting is to limit the "number of api calls" So, we need to focus on REST API response size. API Response size is actually a system level property- i.e. the server will define the payload size. I think, B is correct.

Based in the follwoing definition of REST API Pagination as opposed to REST API Rate limiting in the following resource I think D is correct Pagination: https://nordicapis.com/everything-you-need-to-know-about-api-pagination/ Rate Limiting: https://apisyouwonthate.com/blog/what-is-api-rate-limiting-all-about
