200-901 Question 42
Select 4A development team is integrating with a third-party API to fetch weather data for their application. During implementation, they encounter several challenges. Which of the following are valid constraints when consuming APIs?
- A
Rate limiting imposed by the API provider
- B
Lack of proper API documentation
- C
The API requires a subscription fee for access
- D
The client application must use a specific programming language
- E
Network latency impacting API response times
Show answer and explanation
Correct answers: A, B, C, E
Explanation
When consuming APIs, developers often face constraints like rate limiting, poor documentation, financial costs, and network-related issues. These constraints must be considered during API integration to ensure the application functions correctly and efficiently. However, APIs are generally language-agnostic, so the programming language used by the client is not a constraint.
- A. Correct.
Rate limiting is a common constraint imposed by API providers to control resource usage and prevent abuse.
- B. Correct.
Incomplete or unclear API documentation can make it difficult for developers to understand how to properly use the API.
- C. Correct.
Some APIs require a subscription fee or API key to access, which can be a financial or administrative constraint.
- D. Incorrect.
APIs are designed to be language-agnostic and accessed via standard protocols like HTTP, so this is not a valid constraint.
- E. Correct.
Network latency can impact the performance of an application that consumes an API, especially if the API is hosted on a server geographically far from the client.
