3. Question 93 · 325 in bank

   Your company has developed a new application that consists of multiple microservices. You want to deploy the application to Google Kubernetes Engine (GKE), and you want to ensure that the cluster can scale as more applications are deployed in the future. You want to avoid manual intervention when each new application is deployed. What should you do?

   • ADeploy the application on GKE, and add a HorizontalPodAutoscaler to the deployment.
   • BDeploy the application on GKE, and add a VerticalPodAutoscaler to the deployment.
   • CCreate a GKE cluster with autoscaling enabled on the node pool. Set a minimum and maximum for the size of the node pool.
   • DCreate a separate node pool for each application, and deploy each application to its dedicated node pool.

   Show answer

   Answer: C

   Explanation

   Answer is C The key point is "ensure that the CLUSTER can scale" A- HorizontalPodAutoscaler - ensures to scale the number of pods while C- Create a GKE cluster with autoscaling enabled on the node pool. Set a minimum and maximum for the size of the node pool. ensures to scale the number of nodes in the cluster. So the answer is C.

4. Question 94 · 325 in bank

   You need to manage a third-party application that will run on a Compute Engine instance. Other Compute Engine instances are already running with default configuration. Application installation files are hosted on Cloud Storage. You need to access these files from the new instance without allowing other virtual machines (VMs) to access these files. What should you do?

   • ACreate the instance with the default Compute Engine service account. Grant the service account permissions on Cloud Storage.
   • BCreate the instance with the default Compute Engine service account. Add metadata to the objects on Cloud Storage that matches the metadata on the new instance.
   • CCreate a new service account and assign this service account to the new instance. Grant the service account permissions on Cloud Storage.
   • DCreate a new service account and assign this service account to the new instance. Add metadata to the objects on Cloud Storage that matches the metadata on the new instance.

   Show answer

   Answer: C

   Explanation

   "without allowing other instances" , the other instances are created with default compute engine service account. So you must create a new independant service account

5. Question 95 · 325 in bank

   You need to configure optimal data storage for files stored in Cloud Storage for minimal cost. The files are used in a mission-critical analytics pipeline that is used continually. The users are in Boston, MA (United States). What should you do?

   • AConfigure regional storage for the region closest to the users. Configure a Nearline storage class.
   • BConfigure regional storage for the region closest to the users. Configure a Standard storage class.
   • CConfigure dual-regional storage for the dual region closest to the users. Configure a Nearline storage class.
   • DConfigure dual-regional storage for the dual region closest to the users. Configure a Standard storage class.

   Show answer

   Answer: B

   Explanation

   Continuous access to data means Standard since all of the other options are for infrequently accessed storage (Nearline, Coldline, Archive). Since no other regions are mentioned, single region is best in this case

6. Question 96 · 325 in bank

   You are developing a new web application that will be deployed on Google Cloud Platform. As part of your release cycle, you want to test updates to your application on a small portion of real user traffic. The majority of the users should still be directed towards a stable version of your application. What should you do?

   • ADeploy the application on App Engine. For each update, create a new version of the same service. Configure traffic splitting to send a small percentage of traffic to the new version.
   • BDeploy the application on App Engine. For each update, create a new service. Configure traffic splitting to send a small percentage of traffic to the new service.
   • CDeploy the application on Kubernetes Engine. For a new release, update the deployment to use the new version.
   • DDeploy the application on Kubernetes Engine. For a new release, create a new deployment for the new version. Update the service to use the new deployment.

   Show answer

   Answer: A

   Explanation

   A all the way. When deploying new versions you can split traffic for A/B testing to see how user base reacts to changes.

   You need to manage a Cloud Spanner instance for best query performance. Your instance in production runs in a single Google Cloud region. You need to improve performance in the shortest amount of time. You want to follow Google best practices for service configuration. What should you do?

   • ACreate an alert in Cloud Monitoring to alert when the percentage of high priority CPU utilization reaches 45%. If you exceed this threshold, add nodes to your instance.
   • BCreate an alert in Cloud Monitoring to alert when the percentage of high priority CPU utilization reaches 45%. Use database query statistics to identify queries that result in high CPU usage, and then rewrite those queries to optimize their resource usage.
   • CCreate an alert in Cloud Monitoring to alert when the percentage of high priority CPU utilization reaches 65%. If you exceed this threshold, add nodes to your instance.
   • DCreate an alert in Cloud Monitoring to alert when the percentage of high priority CPU utilization reaches 65%. Use database query statistics to identify queries that result in high CPU usage, and then rewrite those queries to optimize their resource usage.

   Show answer

   Answer: C

   Explanation

   Taking it back. The answer is C. "Compute capacity defines amount of server and storage resources that are available to the databases in an instance. When you create an instance, you specify its compute capacity as a number of processing units or as a number of nodes, with 1000 processing units being equal to 1 node." https://cloud.google.com/spanner/docs/instances
