Google Professional Cloud Architect Practice Exam 2026/2027 actual
questions and well detailed answers
Question 1
An enterprise financial company is designing a mission-critical global web
application on Google Cloud. The application requires high availability, low
latency for users worldwide, and automatic failover across regions. Which
architecture best meets these requirements?
• A. Deploy a single Compute Engine virtual machine instance in us-central1
backed by Cloud SQL and scale vertically during peak traffic.
• B. Deploy managed instance groups across multiple regions behind a Global
External HTTP(S) Load Balancer, using Cloud Spanner for global
transactional data storage.
• C. Use App Engine standard environment in a single region with a local
MySQL database instance.
• D. Deploy zonal Google Kubernetes Engine (GKE) clusters in each region
connected via manual port forwarding.
• Correct Answer: B
• Explanation: A Global External HTTP(S) Load Balancer routes user traffic to
the closest available region with automatic failover, while Cloud Spanner
provides globally distributed, horizontally scalable transactional consistency.
Question 2
A healthcare startup needs to store millions of medical images (DICOM files)
that require immediate access for analysis less than once a year, but must be
retained for compliance over seven years at the lowest possible storage cost.
Which Cloud Storage class should be selected?
• A. Standard Storage
• B. Nearline Storage
• C. Coldline Storage
• D. Archive Storage
,Google Professional Cloud Architect Practice Exam 2026/2027 actual
questions and well detailed answers
• Correct Answer: D
• Explanation: Archive Storage is the lowest-cost, highly durable storage
service for data archiving, online backup, and disaster recovery, designed
for data accessed less than once a year.
Question 3
Your organization operates a multi-project GCP environment. The security team
mandates that development teams cannot create public IP addresses on their
virtual machine instances, regardless of project permissions. Which feature
should an administrator configure to enforce this organization-wide?
• A. Custom IAM roles assigned to all developers.
• B. Organization Policy constraints (such as
constraints/compute.disableGlobalSerialPortAccess and disabling external
IP creation).
• C. VPC firewall rules blocking egress traffic on port 80.
• D. Manual code reviews of Terraform scripts before deployment.
• Correct Answer: B
• Explanation: Organization Policies allow administrators to centrally
configure and enforce declarative constraints (such as restricting external IP
addresses) across folders, projects, or the entire organization.
Question 4
A retail company is migrating a self-hosted monolithic application running on
PostgreSQL to Google Cloud. They want a fully managed relational database
service that automatically scales storage and compute without downtime during
peak holiday shopping events. Which service is the best fit?
• A. Cloud SQL for PostgreSQL
• B. Cloud Spanner
• C. BigQuery
,Google Professional Cloud Architect Practice Exam 2026/2027 actual
questions and well detailed answers
• D. Firestore in Datastore mode
• Correct Answer: A
• Explanation: Cloud SQL provides fully managed relational databases with
automated storage increase and high availability, making it the ideal target
for standard PostgreSQL migrations. (Note: Cloud Spanner is for massive
global scale, but Cloud SQL is the standard choice for standard PostgreSQL
monolith migrations unless extreme horizontal scaling across regions is
required).
Question 5
An analytics team wants to execute ad-hoc SQL queries over petabytes of
streaming and batch data stored in Google Cloud without provisioning or
managing underlying servers or clusters. Which GCP service should they use?
• A. Cloud Dataproc
• B. BigQuery
• C. Cloud SQL
• D. Cloud Bigtable
• Correct Answer: B
• Explanation: BigQuery is a fully managed, serverless enterprise data
warehouse designed for lightning-fast SQL queries on petabyte-scale
datasets.
Question 6
A multinational corporation has strict data residency requirements stipulating
that customer Personally Identifiable Information (PII) collected in Europe must
not leave the European Union. When creating GCP resources and datasets, what
should the Cloud Architect ensure?
, Google Professional Cloud Architect Practice Exam 2026/2027 actual
questions and well detailed answers
• A. All resources are deployed in European multi-region or specific EU-based
single regions (e.g., europe-west1), and Resource Location Constraint
organization policies are enforced.
• B. Data is replicated to us-central1 for disaster recovery backup.
• C. Default global routing is enabled on all Virtual Private Cloud (VPC)
networks.
• D. Cloud CDN caches EU data in edge nodes globally outside the EU.
• Correct Answer: A
• Explanation: Enforcing Organization Policies for resource locations
alongside provisioning storage and compute exclusively within EU regions
guarantees adherence to EU data residency rules.
Question 7
Your development team uses Google Kubernetes Engine (GKE) for microservices.
They need a secure way to inject database credentials into pods without storing
secrets in plain text within container images or GitHub repositories. What is the
recommended GCP practice?
• A. Hardcode passwords into environment variables inside Dockerfiles.
• B. Store credentials in Google Cloud Secret Manager and grant the GKE
workload service account permissions to access them at runtime via IAM.
• C. Save secrets in a public ConfigMap inside the Kubernetes cluster.
• D. Transmit passwords via HTTP headers during pod startup.
• Correct Answer: B
• Explanation: Cloud Secret Manager provides secure, centralized storage for
API keys, passwords, and sensitive data, integrating seamlessly with
Workload Identity for secure access from GKE.
