A client consumes an API that returns paginated results via Link headers. The `Link` header includes `rel="next"`, `rel="prev"`, `rel="first"`, and `rel="last"` links. The client is on page 3 of 10. The API returns a 500 error when requesting the `rel="next"` link. What is the best course of action?

Skip to the `rel="last"` link to retrieve the remaining data.

Use the `rel="prev"` link to go back and try again.

Retry the same request with exponential backoff, and if it continues to fail, log the error and stop.

Immediately retry the request without any delay.

What is the primary purpose of pagination in a REST API?

To allow clients to modify the data on the server in smaller batches

To ensure that all records are returned in a single response for consistency

To reduce the amount of data transferred in a single response and improve server performance

To encrypt the data in transit between the client and the server

When aggregating results from multiple pages into a single list, which practice helps avoid duplicates?

Using a set or checking for existing IDs before adding

Ignoring the 'next' link and fetching the same page again

Appending all items without any checks

Sorting the list after each page

In a REST API response, where are pagination links such as next and previous typically provided?

In the Link header of the HTTP response

Which of the following is an example of pagination metadata commonly found in a REST API response body?

"page": 2, "per_page": 50, "total": 120

"status": "success", "message": "OK"

"error": "invalid_token", "code": 401
