Question 2

- (Exam Topic 2)
You have an application that uses an HTTP Cloud Function to process user activity from both desktop browser and mobile application clients. This function will serve as the endpoint for all metric submissions using HTTP POST.
Due to legacy restrictions, the function must be mapped to a domain that is separate from the domain requested by users on web or mobile sessions. The domain for the Cloud Function is https://fn.example.com. Desktop and mobile clients use the domain https://www.example.com. You need to add a header to the function’s HTTP response so that only those browser and mobile sessions can submit metrics to the Cloud Function. Which response header should you add?

A. Access-Control-Allow-Origin: *
B. Access-Control-Allow-Origin: https://*.example.com
C. Access-Control-Allow-Origin: https://fn.example.com
D. Access-Control-Allow-origin: https://www.example.com

https://cloud.google.com/storage/docs/folders
If you create an empty folder using the Google Cloud console, Cloud Storage creates a zero-byte object as a placeholder. For example, if you create a folder called folder in a bucket called my-bucket, a zero- byte object called gs://my-bucket/folder/ is created. This placeholder is discoverable by other tools when listing the objects in the bucket, for example when using the gsutil ls command.
