Explanation

A is incorrect because adding more Frontend servers will not fix the backend configuration B is incorrect because running a backend without the critical security patch is a big risk. C is correct because the remaining 3 regions can handle the total traffic load, which gives you time to fix the configuration error in Region 3 and then apply the patch. D is incorrect because backing up the database will not help at this point, and the additional load on the server could make the problem worse. https://cloud.google.com/load-balancing/docs/enabling-connection-draining https://cloud.google.com/compute/docs/tutorials/robustsystems#distribute https://landing.google.com/sre/sre-book/chapters/addressing-cascading-failures/
