Google Professional Cloud Developer Exam - Topic 4 Question 32 Discussion

Actual exam question for Google's Professional Cloud Developer exam

Question #: 32
Topic #: 4

[All Professional Cloud Developer Questions]

You are writing a single-page web application with a user-interface that communicates with a third-party API for content using XMLHttpRequest. The data displayed on the UI by the API results is less critical than other data displayed on the same web page, so it is acceptable for some requests to not have the API data displayed in the UI. However, calls made to the API should not delay rendering of other parts of the user interface. You want your application to perform well when the API response is an error or a timeout.

What should you do?

ASet the asynchronous option for your requests to the API to false and omit the widget displaying the API results when a timeout or error is encountered.

BSet the asynchronous option for your request to the API to true and omit the widget displaying the API results when a timeout or error is encountered.

CCatch timeout or error exceptions from the API call and keep trying with exponential backoff until the API response is successful.

DCatch timeout or error exceptions from the API call and display the error response in the UI widget.

D might clutter the UI with errors, not a good idea.

Definitely going with B, async is the way to go!

I’m surprised they even suggest option A, that’s so outdated!

I disagree, C could lead to unnecessary retries.

Option B seems like the best choice for non-blocking calls.

Displaying the error in the UI seems like a good idea, but I wonder if option D would clutter the interface too much. I’m leaning towards option B.

I practiced a similar question where we had to handle API errors gracefully. I feel like option C could be a good approach, but it might lead to too many retries.

I'm not entirely sure, but I think setting the async option to false could lead to a poor user experience. Maybe option A isn't the best choice?

I remember that asynchronous requests are important for not blocking the UI, so I think option B makes the most sense.

I know Snowflake's column-level statistics are important, so I'll carefully read the question and think through the implications before answering.

Okay, I remember from class that a rise in production costs leads to a leftward shift of the aggregate supply curve. So the answer has to be B.

This seems like a tricky one. I'll need to carefully review the configuration details to identify the root cause.

Hmm, I'm not sure about this one. The question mentions detecting credentials, but the options seem to be about different types of network connections. I'll have to think this through carefully.

Secure data transactions were mentioned in one of the practice questions, but I think that's more about security than performance metrics. I'm kind of unsure here.
