Sample Exam Questions

Try these 12 original sample questions for Google Cloud Professional Cloud Architect. Use them for study, self-assessment, and exam-scope review. They are not official Google Cloud questions, copied live-exam content, or exam dumps.

Question 1

What this tests: resource hierarchy

A company wants separate billing, IAM boundaries, and policy controls for production and development workloads while keeping both under one organization. Which Google Cloud structure is usually the best starting point?

• A. One project with labels only
• B. Separate projects under folders that reflect environment or business structure
• C. One service account shared by all teams
• D. Public buckets for environment separation

Best answer: B

Explanation: Google Cloud architecture usually starts with organization, folders, and projects to create governance, billing, IAM, and quota boundaries. Labels help reporting but do not replace project boundaries. Shared credentials and public storage weaken control.

Question 2

What this tests: reliability design

A web application must continue serving users if one zone fails. Which design best supports this requirement?

• A. A single VM in one zone with a larger machine type
• B. A manually restored disk snapshot only
• C. A static website hosted on a developer laptop
• D. Managed instance groups or services deployed across multiple zones behind a load balancer

Best answer: D

Explanation: Zonal failure tolerance requires resources in more than one zone and traffic distribution through a load-balancing pattern. Larger single-zone resources still fail with the zone. Manual recovery alone may not satisfy availability requirements.

Question 3

What this tests: IAM least privilege

A data-processing service needs to read from one Cloud Storage bucket and write logs. What is the best identity approach?

• A. Use a dedicated service account with only the required bucket and logging permissions
• B. Give all developers Owner on the project
• C. Use a personal user account for the service
• D. Make the bucket public so IAM is not needed

Best answer: A

Explanation: A dedicated service account with least-privilege roles is the right pattern for workload identity. Broad project ownership, personal accounts, and public buckets increase risk and make access harder to audit.

Question 4

What this tests: migration sequencing

A legacy application has tight database dependencies and limited documentation. The business wants lower migration risk before modernization. Which plan is most reasonable?

• A. Rewrite the entire application and database in one untested cutover
• B. Move production first and document later
• C. Assess dependencies, choose a phased migration, test cutover and rollback, then modernize incrementally
• D. Disable monitoring until after the migration

Best answer: C

Explanation: Architect-level questions reward risk-managed migration. Dependency assessment, phased movement, testing, rollback planning, and incremental modernization reduce failure risk. Big-bang rewrites and missing monitoring are high-risk.

Question 5

What this tests: network access pattern

A private application needs to call Google APIs without routing through the public internet. Which feature should the architect consider?

• A. Public IP addresses on every VM
• B. A shared user password
• C. Disabling all routes
• D. Private Google Access or appropriate private connectivity to Google APIs

Best answer: D

Explanation: Private Google Access lets resources without external IP addresses reach supported Google APIs and services. The exact connectivity design depends on workload and network context, but public IPs and shared passwords are not the right security pattern.

Question 6

What this tests: data storage selection

An application needs globally scalable object storage for images and backups, with lifecycle policies to move older objects to lower-cost classes. Which service is the best fit?

• A. Cloud SQL
• B. Cloud Storage
• C. Memorystore
• D. Pub/Sub

Best answer: B

Explanation: Cloud Storage is object storage and supports storage classes and lifecycle policies. Cloud SQL is relational, Memorystore is in-memory caching, and Pub/Sub is messaging.

Question 7

What this tests: observability

After a release, users report intermittent latency. The team needs metrics, logs, traces, and alerting around service behavior. Which Google Cloud capability should be part of the design?

• A. Cloud Billing export only
• B. Google Cloud Marketplace listings
• C. Cloud Monitoring, Cloud Logging, and Cloud Trace where appropriate
• D. Manual screenshots of the console

Best answer: C

Explanation: Production architectures need observable signals. Monitoring, logging, tracing, and alerts help identify performance and reliability issues. Billing export and screenshots do not provide runtime diagnostics.

Question 8

What this tests: cost-aware architecture

A batch analytics job runs once per night and can tolerate interruption, but it needs high compute capacity while it runs. Which design is most cost-aware?

• A. Use preemptible or spot-style compute where appropriate and design the job to checkpoint or retry
• B. Keep maximum-size VMs running all day
• C. Use a global external load balancer as the main cost-control tool
• D. Store intermediate files only on local disks with no retry strategy

Best answer: A

Explanation: Interruptible compute can reduce cost for fault-tolerant batch jobs, but the architecture must handle interruption through checkpointing, retry, or idempotent processing. Always-on oversized compute wastes capacity.

Question 9

What this tests: stakeholder requirements

A business sponsor asks for “the most secure architecture” without defining constraints. What should the architect do first?

• A. Pick the most expensive controls available
• B. Clarify business requirements, compliance needs, data sensitivity, user flows, and operational constraints
• C. Deny all traffic permanently
• D. Build the solution before speaking to stakeholders

Best answer: B

Explanation: Architecture starts with requirements and constraints. Security must be designed around data, users, compliance, operations, and risk tolerance. Unbounded or undefined security goals cannot be implemented responsibly.

Question 10

What this tests: disaster recovery

A database-backed application has a recovery time objective of minutes and a recovery point objective near zero. Which DR approach is most aligned?

• A. Weekly manual exports stored locally
• B. No backup because the application is stateless
• C. One VM snapshot taken before each holiday
• D. Replication or highly available managed database architecture with tested failover procedures

Best answer: D

Explanation: Low RTO and low RPO require architecture that keeps data current and failover tested. Weekly exports or ad hoc snapshots cannot meet near-zero data loss and minute-level recovery.

Question 11

What this tests: compliance and data location

A workload processes regulated customer data that must stay in an approved region. What should the architect include in the design?

• A. Deploy wherever latency is lowest and ignore policy
• B. Put the data in public buckets so auditors can inspect it
• C. Use approved regions, organization policies where applicable, and controls that prevent unsupported data movement
• D. Allow every developer to copy data to personal projects

Best answer: C

Explanation: Regulatory and residency requirements must be reflected in region selection, policy controls, IAM, data movement controls, and auditing. Convenience or public access does not satisfy compliance obligations.

Question 12

What this tests: implementation planning

A proposed architecture depends on several managed services and a new deployment pipeline. What is the best implementation approach?

• A. Define milestones, test environments, rollback plans, operational readiness, and clear ownership
• B. Deploy directly to production with no runbook
• C. Wait until after launch to define monitoring
• D. Give every user project Owner until issues stop

Best answer: A

Explanation: Professional architecture includes implementation planning: milestones, testing, rollback, observability, security review, and operational ownership. Production deployment without readiness planning creates avoidable risk.
