Question #: 2
Topic #: 6
For this question, refer to the Mountkirk Games case study. You need to analyze and define the technical architecture for the compute workloads for your company, Mountkirk Games. Considering the Mountkirk Games business and technical requirements, what should you do?
A. Create network load balancers. Use preemptible Compute Engine instances. B. Create network load balancers. Use non-preemptible Compute Engine instances. C. Create a global load balancer with managed instance groups and autoscaling policies. Use preemptible Compute Engine instances. D. Create a global load balancer with managed instance groups and autoscaling policies. Use non-preemptible Compute Engine instances.
https://www.examtopics.com/discussions/google/view/8500-exam-professional-cloud-architect-topic-6-question-2/
D. Create a global load balancer with managed instance groups and autoscaling policies. Use non-preemptible Compute Engine instances
Based on the provided requirements, the recommended solution is to use Google Compute Engine for the game backend platform and game analytics platform. The backend platform needs to dynamically scale up or down based on game activity and connect to a transactional database service to manage user profiles and game state. The platform also needs to store game activity in a timeseries database service for future analysis and ensure that data is not lost due to processing backlogs. The platform should run on a hardened Linux distro. On the other hand, the analytics platform needs to dynamically scale up or down based on game activity and process incoming data on the fly directly from the game servers. It should also process data that arrives late because of slow mobile networks and allow queries to access at least 10 TB of historical data. Additionally, the analytics platform should process files that are regularly uploaded by users’ mobile devices.
Given these requirements, the recommended solution is to create a global load balancer with managed instance groups and autoscaling policies. This solution provides high availability and allows the game backend and analytics platforms to dynamically scale up or down based on game activity. Managed instance groups allow for easy scaling of instances and autoscaling policies ensure that there are enough instances to handle the load. The global load balancer ensures that the game is available to players worldwide and reduces latency.
There are two options for the type of instances to use: preemptible or non-preemptible Compute Engine instances. Preemptible instances are cheaper, but Google can terminate them at any time with a 30-second notice. Non-preemptible instances are more expensive, but they are not terminated until the user stops them or deletes them.

For this question, refer to the Mountkirk Games case study. Mountkirk Games wants to design their solution for the future in order to take advantage of cloud and technology improvements as they become available. Which two steps should they take? (Choose two.)
A. Store as much analytics and game activity data as financially feasible today so it can be used to train machine learning models to predict user behavior in the future. B. Begin packaging their game backend artifacts in container images and running them on Google Kubernetes Engine to improve the ability to scale up or down based on game activity. C. Set up a CI/CD pipeline using Jenkins and Spinnaker to automate canary deployments and improve development velocity. D. Adopt a schema versioning tool to reduce downtime when adding new game features that require storing additional player data in the database. E. Implement a weekly rolling maintenance process for the Linux virtual machines so they can apply critical kernel patches and package updates and reduce the risk of 0-day vulnerabilities.
