[All Professional Cloud Architect Questions]

Your company's test suite is a custom C++ application that runs tests throughout each day on Linux virtual machines. The full test suite takes several hours to complete, running on a limited number of on-premises servers reserved for testing. Your company wants to move the testing infrastructure to the cloud, to reduce the amount of time it takes to fully test a change to the system, while changing the tests as little as possible.
Which cloud infrastructure should you recommend?

  • A. Google Compute Engine unmanaged instance groups and Network Load Balancer
  • B. Google Compute Engine managed instance groups with auto-scaling
  • C. Google Cloud Dataproc to run Apache Hadoop jobs to process each test
  • D. Google App Engine with Google StackDriver for logging

Selected Answer: B
Changing the tests as little as possible rules out C & D. Test takes several hours and you need to improve perfromace. Autocaling with MIG will do it Unmanaged group cannot autosacle. Load balancer will not improve perfromance

I second the question. The App might not support horizontal scaling. But I also admit that no other answer is valid. A: The Load Balancer offers no benefit. C: Hadoop doesn't process C++ D: App Engine is for web apps.

New Question Your company has a Kubernetes application that pulls messages from Pub/Sub and stores them in Filestore. Because the application is simple, it was deployed as a single pod. The infrastructure team has analyzed Pub/Sub metrics and discovered that the application cannot process the messages in real time. Most of them wait for minutes before being processed. You need to scale the elaboration process that is 1/0-intensive. What should you do? A. Usekubectl autoscale deployment APP_NAME --max 6 --min 2 --cpu-percent 50 to configure Kubernetes autoscaling deployment. B. Configure a Kubemetes autoscaling deployment based on the subscription/push_request_latencies metric. C. Use the --enable-autoscaling flag when you create the Kubernetes cluster. D. Configure a Kubernetes autoscaling deployment based on the subscription/num_undelivered_messages metric.
