Three of the 379 questions in this pack

Question 1

You want to upload files from an on-premises virtual machine to Google Cloud Storage as part of a data migration. These files will be consumed by Cloud DataProc Hadoop cluster in a GCP environment. Which command should you use?

  1. gsutil cp [LOCAL_OBJECT] gs://[DESTINATION_BUCKET_NAME]/
  2. gcloud cp [LOCAL_OBJECT] gs://[DESTINATION_BUCKET_NAME]/
  3. hadoop fs cp [LOCAL_OBJECT] gs://[DESTINATION_BUCKET_NAME]/
  4. gcloud dataproc cp [LOCAL_OBJECT] gs://[DESTINATION_BUCKET_NAME]/
Show answer and explanation

Correct answer: A. gsutil cp [LOCAL_OBJECT] gs://[DESTINATION_BUCKET_NAME]/

gs://[DESTINATION_BUCKET_NAME]/ gsutil is the correct command-line tool for transferring files to and from Google Cloud Storage. The cp subcommand copies files, and the gs:// URI scheme specifies the Cloud Storage bucket destination. This is the standard tool used for data migration to GCS, including data that will be consumed by DataProc clusters.

Why the other options are wrong

  • B. gcloud cp is not a valid command; gcloud does not have a cp subcommand for file transfers.
  • C. hadoop fs cp is a Hadoop command that works with HDFS and Hadoop-compatible filesystems, not the primary tool for uploading from on-premises to GCS.
  • D. gcloud dataproc cp is not a valid command; DataProc does not have a cp subcommand for file transfers.

Question 2

You migrated your applications to Google Cloud Platform and kept your existing monitoring platform. You now find that your notification system is too slow for time critical problems. What should you do?

  1. Replace your entire monitoring platform with Stackdriver.
  2. Install the Stackdriver agents on your Compute Engine instances.
  3. Use Stackdriver to capture and alert on logs, then ship them to your existing platform.
  4. Migrate some traffic back to your old platform and perform AB testing on the two platforms concurrently.
Show answer and explanation

Correct answer: C. Use Stackdriver to capture and alert on logs, then ship them to your existing platform.

ship them to your existing platform. When keeping an existing monitoring platform while using GCP resources, the optimal approach is to use Stackdriver to capture logs and alerts, then forward this data to your existing platform. This provides the speed and native GCP integration of Stackdriver for alerting while maintaining your existing monitoring infrastructure and avoiding the cost and effort of a complete platform replacement.

Why the other options are wrong

  • A. Replacing the entire monitoring platform is unnecessarily disruptive and costly when your existing platform can still serve a purpose in a hybrid setup.
  • B. Installing only agents does not solve the core problem of slow notifications; you still need a faster alerting mechanism integrated with GCP.
  • D. AB testing between platforms and migrating traffic back is operationally complex and does not address the slow notification problem.

Question 3

You are planning to migrate a MySQL database to the managed Cloud SQL database for Google Cloud. You have Compute Engine virtual machine instances that will connect with this Cloud SQL instance. You do not want to whitelist IPs for the Compute Engine instances to be able to access Cloud SQL. What should you do?

  1. Enable private IP for the Cloud SQL instance.
  2. Whitelist a project to access Cloud SQL, and add Compute Engine instances in the whitelisted project.
  3. Create a role in Cloud SQL that allows access to the database from external instances, and assign the Compute Engine instances to that role.
  4. Create a CloudSQL instance on one project. Create Compute engine instances in a different project. Create a VPN between these two projects to allow internal access to CloudSQL.
Show answer and explanation

Correct answer: A. Enable private IP for the Cloud SQL instance.

Enabling private IP for a Cloud SQL instance allows Compute Engine instances in the same VPC network to connect without requiring IP whitelisting. This is the modern, secure approach that eliminates the need for public IP exposure and whitelist management while maintaining internal connectivity within Google Cloud.

Why the other options are wrong

  • B. IP whitelisting is the opposite of what the requirement asks for; the goal is to avoid whitelisting IPs.
  • C. Cloud SQL does not use roles to grant database access from external instances; roles control IAM permissions on the Cloud SQL instance itself, not network access.
  • D. Creating a VPN between projects is unnecessarily complex when both resources are in Google Cloud; private IP is the simpler, native solution.

What makes the Professional Cloud Developer exam hard

The Professional Cloud Developer exam guide was rewritten around AI-assisted development. The current version expects candidates to use generative AI APIs in applications and to work with AI coding assistants, MCP servers, Gemini Cloud Assist and AI-assisted observability as part of the job, and it dropped the old App Engine and Cloud Functions emphasis in favour of Cloud Run and GKE. A bank built on the 2023 guide is missing a whole layer.

Designing scalable, secure and reliable cloud-native applications is about a third of the exam: choosing between Compute Engine, GKE and Cloud Run, REST and gRPC APIs, event-driven integration with Eventarc and Pub/Sub, security with IAP, Secret Manager and Workload Identity Federation, and choosing between AlloyDB, Spanner, Bigtable, Firestore, Cloud SQL, Cloud Storage and BigQuery with their consistency models.

Configuring for deployment at about 24% is Cloud Run from source, Eventarc triggers and GKE autoscaling. Building and testing at about 23% covers Cloud Build, Artifact Registry and AI-written unit tests. Integrating at about 21% covers datastore connections, messaging and Google Cloud Observability.

About the exam
