Google Cloud Professional Cloud Network Engineer — Question 229

Your organization is launching a new video game that will be available to all users globally through Cloud CDN. During the earl y release phase, you discovered that the wrong binary version was uploaded from Cloud Storage and cached in Cloud CDN. Thousands of users have downloaded the wrong version. Your marketing department has notified users that this was the wrong version of the game and asked all users to download the updated version using the same URL. You need to ensure users are downloading the updated version of the game. What should you do?

Answer options

• A. Create a security policy to block all Cloud CON requests, review the logs, and filter which users are attempting to download the wrong game binary.
• B. Create a new URL path for the updated game binary. Allow the cache to expire automatically through HTTP headers.
• C. Upload the updated game binary to Cloud Storage. Invalidate the wrong game binary from the Cloud CDN cache.
• D. Disable Cloud CDN. Reconfigure the load balancer with the updated game binary. Enable Cloud CDN.

Correct answer: C

Explanation

The correct answer is C because uploading the updated binary to Cloud Storage and invalidating the cached version in Cloud CDN ensures that users will receive the latest version without changing the URL. Options A and D involve unnecessary disruptions, while B would not guarantee that users receive the updated version immediately since it relies on cache expiration.
