GCP Certification Exam Practice Questions

  • Questions are collected from Internet and the answers are marked as per my knowledge and understanding (which might differ with yours).
  • GCP services are updated everyday and both the answers and questions might be outdated soon, so research accordingly.
  • GCP exam questions are not updated to keep up the pace with GCP updates, so even if the underlying feature has changed the question might not be updated
  • Open to further feedback, discussion and correction.
  1. You have a development project with appropriate IAM roles defined. You are creating a production project and want to have the same IAM roles on the new project, using the fewest possible steps. What should you do?
    1. Use gcloud iam roles copy and specify the production project as the destination project.
    2. Use gcloud iam roles copy and specify your organization as the destination organization.
    3. In the Google Cloud Platform Console, use the ‘create role from role’ functionality.
    4. In the Google Cloud Platform Console, use the ‘create role’ functionality and select all applicable permissions.
  2. Your team is working on GKE cluster named dev. You have downloaded and installed the gcloud command line interface (CLI) and SDK. You want to avoid having to specify this GKE config with each CLI command when managing this cluster. What should you do?
    1. Set the dev cluster as the default cluster using the gcloud container update dev
    2. Set the dev cluster as the default cluster using the gcloud config set container/cluster dev
    3. Set the dev cluster as the default cluster by adding the config to gke.default in ~/gcloud folder
    4. Set the dev cluster as the default cluster by adding the config to defaults.json in ~/gcloud folder
  3. You have a Kubernetes cluster with 1 node-pool. The cluster receives a lot of traffic and needs to grow. You decide to add a node. What should you do?
    1. Use “gcloud container clusters resize” with the desired number of nodes.
    2. Use “kubectl container clusters resize” with the desired number of nodes.
    3. Edit the managed instance group of the cluster and increase the number of VMs by 1.
    4. Edit the managed instance group of the cluster and enable autoscaling.
  4. You’re trying to provide temporary access to some files in a Cloud Storage bucket with 20 minutes availability. What is the best way to generate a signed URL?
    1. Create a service account and JSON key. Use the gsutil signurl -t 20m command and pass in the JSON key and bucket.
    2. Create a service account and JSON key. Use the gsutil signurl -d 20m command and pass in the JSON key and bucket.
    3. Create a service account and JSON key. Use the gsutil signurl -p 20m command and pass in the JSON key and bucket.
    4. Create a service account and JSON key. Use the gsutil signurl -m 20m command and pass in the JSON key and bucket.
