PROFESSIONAL-CLOUD-ARCHITECT · Question #167
Case Study: 7 - Mountkirk Games Company Overview Mountkirk Games makes online, session-based, multiplayer games for mobile platforms. They build all of their games using some server-side integration.
The correct answer is C. Create an instance template for the backend. For every region, deploy it on a multi-zone. Multi-zone managed instance groups combined with a global load balancer provide both high availability within each region and global traffic distribution for Mountkirk's game backend.

Why each option
Multi-zone managed instance groups combined with a global load balancer provide both high availability within each region and global traffic distribution for Mountkirk's game backend.
This option likely uses a regional load balancer instead of global, which cannot route traffic across regions to the nearest backend.
A single-zone MIG introduces a zone-level single point of failure, violating high availability requirements for a popular game.
A multi-zone managed instance group (MIG) distributes VM instances across multiple zones within a region, eliminating single-zone failures; pairing it with a global HTTPS load balancer routes players to the nearest healthy regional MIG, satisfying both availability and low-latency requirements for a globally distributed game backend.
A single-zone MIG with a global load balancer still has zone-level availability risk and does not meet the resilience requirements.
