You need to deploy a new service to production. The service needs to automatically scale using a Managed Instance Group (MIG) and should be deployed over multiple regions. The service needs a large number of resources for each instance and you need to plan for capacity. What should you do?

• A.Use the n2-highcpu-96 machine type in the configuration of the MIG.
• B.Monitor results of Stackdriver Trace to determine the required amount of resources.
• C.Validate that the resource requirements are within the available quota limits of each region.
• D.Deploy the service in one region and use a global load balancer to route traffic to this region.

You are configuring the frontend tier of an application deployed in Google Cloud The frontend tier is hosted in ngmx and deployed using a managed instance group with an Envoy-based external HTTP(S) load balancer in front The application is deployed entirely within the europe-west2 region: and only serves users based in the United Kingdom. You need to choose the most cost-effective network tier and load balancing configuration What should you use?

• A.Premium Tier with a global load balancer
• B.Premium Tier with a regional load balancer

Your application services run in Google Kubernetes Engine (GKE). You want to make sure that only images from your centrally-managed Google Container Registry (GCR) image registry in the altostrat-images project can be deployed to the cluster while minimizing development time. What should you do?

• A.Add logic to the deployment pipeline to check that all manifests contain only images from gcr.io/altostrat-images.
• B.Use a Binary Authorization policy that includes the whitelist name pattern gcr.io/attostrat-images/.
• C.Create a custom builder for Cloud Build that will only push images to gcr.io/altostrat-images.
• D.Add a tag to each image in gcr.io/altostrat-images and check that this tag is present when the image is deployed.

You support a stateless web-based API that is deployed on a single Compute Engine instance in the europe-west2-a zone . The Service Level Indicator (SLI) for service availability is below the specified Service Level Objective (SLO). A postmortem has revealed that requests to the API regularly time out. The time outs are due to the API having a high number of requests and running out memory. You want to improve service availability. What should you do?

• A.Change the specified SLO to match the measured SLI.
• B.Set up additional service instances in other zones and load balance the traffic between all instances.
• C.Move the service to higher-specification compute instances with more memory.
• D.Set up additional service instances in other zones and use them as a failover in case the primary instance is unavailable.
