You are currently pushing container images to Artifact Registry and deploying a containerized microservices application to GKE. After deploying the application, you notice that the services do not behave as expected. You use the kubectl get pods command to inspect the state of the application Pods, and discover that one of the Pods has a state of CrashLoopBackoff. How should you troubleshoot the Pod?

• A.Connect to the problematic Pod by running the kubectl exec -it POD_NAME - /bin/bash command where the POD_NAME parameter is the name of the problematic Pod. Inspect the logs in the
  /var/log/messages folder to determine the root cause.
• B.Execute the gcloud projects get-iam-policy PROJECT_ID command where the PROJECT_ID parameter is the name of the project where your Artifact Registry resides. Inspect the IAM bindings of the node pool's service account. Validate if the service account has the roles/artifactregistry.reader role.
• C.Run the kubectl logs POD_NAME command where the POD_NAME parameter is the name of the problematic Pod. Analyze the logs of the Pod from previous runs to determine the root cause of failed start attempts of the Pod.
• D.In the Google Cloud console, navigate to Cloud Logging in the project of the cluster's VPC. Enter a filter to show denied egress traffic to the Private Google Access CIDR range. Validate if egress traffic is denied from your GKE cluster to the Private Google Access CIDR range.

Your team is developing a Cloud Function triggered by Cloud Storage Events. You want to accelerate testing and development of your Cloud Function while following Google-recommended best practices. What should you do?

• A.Install the Functions Frameworks library, and configure the Cloud Function on localhost. Make a copy of the function, and make edits to the new version Test the new version using cur1.
• B.Make a copy of the Cloud Function, and rewrite the code to be HTTP-triggered Edit and test the new version by triggering the HTTP endpoint. Send mock requests to the new function to evaluate the functionality.
• C.Make a copy of the Cloud Function in the Google Cloud Console Use the Cloud console's in-line editor to make source code changes to the new function Modify your web application to call the new function and test the new version in production.
• D.Create a new Cloud Function that is triggered when Cloud Audit Logs detects the cloudfunctions. functions. sourceCodeSet operation in the original Cloud Function Send mock

You have a web application that publishes messages to Pub/Sub. You plan to build new versions of the application locally and need to quickly test Pub/Sub integration tor each new build. How should you configure local testing?

• A.Install Cloud Code on the integrated development environment (IDE) Navigate to Cloud APIs, and enable Pub/Sub against a valid Google Project ID. When developing locally, configure your application to call pubsub.googleapis com
• B.In the Google Cloud console, navigate to the API Library and enable the Pub/Sub API When developing locally, configure your application to call pubsub.googleapis com
• C.Install the Pub/Sub emulator using gcloud and start the emulator with a valid Google Project ID. When developing locally, configure your application to use the local emulator by exporting the fuhsub emulator Host variable
• D.Run the gclcud config set api_endpoint_overrides/pubsub https: / 'pubsubemulator.googleapi3.com.
  coin/ command to change the Pub/Sub endpoint prior to starting the application

You are using the Cloud Client Library to upload an image in your application to Cloud Storage. Users of the application report that occasionally the upload does not complete and the client library reports an HTTP 504 Gateway Timeout error. You want to make the application more resilient to errors. What changes to the application should you make?

• A.Write a one-second wait time backoff process around the client library call.
• B.Create a queue for the object and inform the users that the application will try again in 10 minutes.
• C.Write an exponential backoff process around the client library call.
• D.Design a retry button in the application and ask users to click if the error occurs.

Your team develops stateless services that run on Google Kubernetes Engine (GKE). You need to deploy a new service that will only be accessed by other services running in the GKE cluster.
The service will need to scale as quickly as possible to respond to changing load. What should you do?

• A.Use a Vertical Pod Autoscaler to scale the containers, and expose them via a ClusterIP Service.
• B.Use a Vertical Pod Autoscaler to scale the containers, and expose them via a NodePort Service.
• C.Use a Horizontal Pod Autoscaler to scale the containers, and expose them via a ClusterIP Service.
• D.Use a Horizontal Pod Autoscaler to scale the containers, and expose them via a NodePort Service.
