Your team uses Cloud Build for all CI/CO pipelines. You want to use the kubectl builder for Cloud Build to deploy new images to Google Kubernetes Engine (GKE). You need to authenticate to GKE while minimizing development effort. What should you do?

• A.Assign the Container Developer role to the Cloud Build service account.
• B.Specify the Container Developer role for Cloud Build in the cloudbuild.yaml file.
• C.Create a separate step in Cloud Build to retrieve service account credentials and pass these to kubectl.
• D.Create a new service account with the Container Developer role and use it to run Cloud Build.

Your team is designing a new application for deployment into Google Kubernetes Engine (GKE). You need to set up monitoring to collect and aggregate various application-level metrics in a centralized location. You want to use Google Cloud Platform services while minimizing the amount of work required to set up monitoring. What should you do?

• A.Publish various melrics from the application directly to the Slackdriver Monitoring API, and then observe these custom metrics in Stackdriver.
• B.Install the OpenTelemetry client libraries in the application, configure Stackdriver as the export destination for the metrics, and then observe the application's metrics in Stackdriver.
• C.Install the Cloud Pub/Sub client libraries, push various metrics from the application to various topics, and then observe the aggregated metrics in Stackdriver.
• D.Emit all metrics in the form of application-specific log messages, pass these messages from the containers to the Stackdriver logging collector, and then observe metrics in Stackdriver.

You have a set of applications running on a Google Kubernetes Engine (GKE) cluster, and you are using Stackdriver Kubernetes Engine Monitoring. You are bringing a new containerized application required by your company into production. This application is written by a third party and cannot be modified or reconfigured. The application writes its log information to /var/log/app_messages.log, and you want to send these log entries to Stackdriver Logging. What should you do?

• A.Use the default Stackdriver Kubernetes Engine Monitoring agent configuration.
• B.Deploy a Fluentd daemonset to GKE. Then create a customized input and output configuration to tail the log file in the application's pods and write to Slackdriver Logging.
• C.Install Kubernetes on Google Compute Engine (GCE> and redeploy your applications. Then customize the built-in Stackdriver Logging configuration to tail the log file in the application's pods and write to Stackdriver Logging.
• D.Write a script to tail the log file within the pod and write entries to standard output. Run the script as a sidecar container with the application's pod. Configure a shared volume between the containers to allow the script to have read access to /var/log in the application container.

You manage an application that is writing logs to Stackdriver Logging. You need to give some team members the ability to export logs. What should you do?

• A.Grant the team members the IAM role of logging.configWriter on Cloud IAM.
• B.Configure Access Context Manager to allow only these members to export logs.
• C.Create and grant a custom IAM role with the permissions logging.sinks.list and logging.sink.get.
• D.Create an Organizational Policy in Cloud IAM to allow only these members to create log exports.

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.Deploy the service in one region and use a global load balancer to route traffic to this region.
• B.Validate that the resource requirements are within the available quota limits of each region.
• C.Use the n1-highcpu-96 machine type in the configuration of the MIG.
• D.Monitor results of Stackdriver Trace to determine the required amount of resources.
