APIs: development, management, testing and documentation​

How can versioning be used to improve the long-term maintainability of an API?

• By making all changes to the API backward-compatible

• By completely overhauling the API every time a change is made

• By keeping the API unchanged and adding new features through a separate API

• By using a versioning scheme and maintaining multiple versions of the API concurrently

How can API documentation be used to improve the developer experience?

• By including as little information as possible to save time and effort

• By writing the documentation in a complex and technical language

• By providing clear, concise, and up-to-date documentation that covers all aspects of the API

• By including only the documentation for the most frequently used endpoints

What is a best practice for securing an API?

• Relying on the security of the underlying transport layer (e.g. HTTPS)

• Storing sensitive data in plain text within the API

• Using a combination of authentication, authorization, and encryption to secure the API

• Disabling all security measures to improve performance

What is a best practice for testing and debugging an API?

• Testing the API only once before deployment

• Testing the API manually without any automated tools

• Testing the API thoroughly using a combination of automated and manual testing techniques

• Relying on users to report any issues or bugs they encounter

How can an API gateway be used to improve the security of an API?

• By serving as a single point of entry for all API requests, allowing for centralized security measures such as authentication and authorization

• By randomly generating new security measures for each API request

• By disabling all security measures to improve performance

• API gateway should not be used for improving security. This responsibility should be under the backends that API proxies to.

What is a best practice for maintaining the performance of an API?

• Neglecting to monitor or optimize the performance of the API

• Making frequent, major changes to the API without considering the impact on performance

• Using caching and other performance optimization techniques to improve the speed and scalability of the API

• Rate limit all endpoint requests to 1 per minute

What is the primary purpose of HTTP?

• To transfer files between computers

• To facilitate communication between clients and servers

• To provide a user interface for interacting with websites

• To secure the transmission of data over the internet

What is an HTTP status code?

• A code used to indicate the success or failure of an HTTP request

• A code used to indicate the type of content being transferred in an HTTP response

• A code used to authenticate the user making an HTTP request

• A code used to encrypt the data being transferred in an HTTP request or response

What is a REST API endpoint?

• A specific URI that represents a resource or a collection of resources in a REST API

• A specific HTTP method used in a REST API

• A specific HTTP status code used in a REST API

• A specific HTTP header used in a REST API

What is a RESTful API?

• An API that uses the REST architecture to provide a standardized interface for communication between clients and servers

• An API that uses the REST architecture to transfer files between computers

• An API that provides a user interface for interacting with websites

• An API that uses the REST architecture to secure the transmission of data over the internet
