Which statement about synchronous and asynchronous API calls is true?
Click on the arrows to vote for the correct answerA. B. C. D.
API (Application Programming Interface) calls are used by applications to communicate with each other or with a server. API calls can be synchronous or asynchronous, and each has its own advantages and disadvantages.
A. Synchronous API calls wait to return until a response has been received. This is true. Synchronous API calls require the application to wait for a response from the server before continuing with its execution. This means that the application is blocked until the response is received, which can lead to performance issues if the response time is long.
B. Synchronous communication is harder to follow and troubleshoot. This statement is not necessarily true. Synchronous communication can be easier to follow and troubleshoot since it follows a sequential order. However, if there are issues with the API call, it can be harder to recover since the application is blocked until the response is received.
C. Synchronous API calls must always use a proxy server. This statement is not true. The use of a proxy server is not dependent on whether the API call is synchronous or asynchronous.
D. Asynchronous communication uses more overhead for client authentication. This statement is not true. Asynchronous communication does not use more overhead for client authentication. However, it may require additional code to manage the asynchronous communication, which can increase the complexity of the application.
In summary, the correct statement is A. Synchronous API calls wait to return until a response has been received.
