Exam Professional Cloud Developer topic 1 question 26 discussion

Answer is B. Api should not delay rendering: asynchronous Application perform well when Api error or timeout: omit the widget

Correct answer is B Asynchronous handling provides the ability to call the API in the background without blocking the rendering of other elements. If the response is received it can be rendered or omitted if a timeout occurs.

B. Asynchronous requests allow the browser to continue processing other tasks while waiting for the API response. If the response is an error or a timeout, you can handle this gracefully by not displaying the widget or showing a message indicating that the data couldn't be loaded. This way, the performance of the rest of your page remains unaffected.

About synchronous=true is more comfortable for user experience.

Correct Answer B.

Setting the asynchronous option to true means that the requests will not block the main thread and will be executed in the background. Furthermore, so as written in the description the widget can be omitted

A is not the correct answer because setting the asynchronous option for the API request to false will block rendering of the user interface until the API response is received. This can cause a delay in rendering other parts of the user interface and negatively impact the performance of the application. B is the correct answer because setting the asynchronous option for the API request to true allows the user interface to continue rendering while the API request is being processed, which improves the performance of the application. Omitting the widget displaying the API results when a timeout or error is encountered allows the application to continue functioning without waiting for a successful API response.

B is correct

B is right one

Understanding the question correctly, the answer should be B

In will vote C, as we can catch the error and retry api again, it is like we us amazone we select a project and we see pricing and other content as the picture are loaded asyn.

can't achieve using synchronous requests, so answer must be B.

Answer is B

It should be B), isn't it? Proposed answer A) uses synchronous behaviour so will block execution, it contradicts the question

"calls made to the API should not delay rendering" -> so A cannot be the answer as it makes Synchronous requests. B is a better option
