NEW QUESTION 119
You are developing a web application that contains private images and videos stored in a Cloud Storage bucket. Your users are anonymous and do not have Google Accounts. You want to use your application-specific logic to control access to the images and videos. How should you configure access?
- A. Cache each web application user's IP address to create a named IP table using Google Cloud Armor.
Create a Google Cloud Armor security policy that allows users to access the backend bucket. - B. Grant the Storage Object Viewer IAM role to allUsers. Allow users to access the bucket after authenticating through your web application.
- C. Generate a signed URL that grants read access to the bucket. Allow users to access the URL after authenticating through your web application.
- D. Configure Identity-Aware Proxy (IAP) to authenticate users into the web application. Allow users to access the bucket after authenticating through IAP.
Answer: C
Explanation:
Explanation
https://cloud.google.com/storage/docs/access-control/signed-urls#should-you-use In some scenarios, you might not want to require your users to have a Google account in order to access Cloud Storage, but you still want to control access using your application-specific logic. The typical way to address this use case is to provide a signed URL to a user, which gives the user read, write, or delete access to that resource for a limited time. You specify an expiration time when you create the signed URL. Anyone who knows the URL can access the resource until the expiration time for the URL is reached or the key used to sign the URL is rotated.

You are developing an application that needs to store files belonging to users in Cloud Storage. You want each user to have their own subdirectory in Cloud Storage. When a new user is created, the corresponding empty subdirectory should also be created. What should you do?
- A. Create an object with the name of the subdirectory ending with a trailing slash ('/') that is zero bytes in length.

- C. Create an object with the name of the subdirectory, and then immediately delete the object within that subdirectory.
- D. Create an object with the name of the subdirectory that is zero bytes in length and has WRITER access control list permission.
Answer: A
Explanation:
Explanation
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.
