Practice Test 4 | Google Cloud Certified Professional Cloud Network Engineer | Dumps | Mock Test
Your team is manages an application that is deployed behind a load balancer and content is cached closer to users globally using the Cloud CDN. A recent update to the backend content used the wrong files and there is an immediate need to clear that content from all caches globally.
Which of the following is a cost effective way and Google’s suggested approach to resolve this?
A. Turn off Cloud CDN on the load balancer
B. Delete the files from the backend
C. Upload a new version of the update to override the current one
D. Use cache invalidation to remove content from the cache locations
Answer: C
Option A is incorrect, this would affect the application’s performance by increasing latency for users far away from the application’s region.
Option B is incorrect. This does not clear the cached content.
Option C is correct. This serves a different version of the same content, effectively removing it by showing users new content before the cache entry expires
Option D is incorrect, this removes content from the Cloud CDN distributed cache servers before the cache entry expires but it is not Google’s recommended approach.
