Google Professional Cloud Architect Practice
Test Exam
1. A company is migrating a legacy monolithic application to
Google Cloud. The application has unpredictable traffic patterns
with occasional spikes. The development team wants to
minimize operational overhead while maintaining the ability to
scale independently. Which compute service should you
recommend?
A) Compute Engine with managed instance groups
B) Google Kubernetes Engine (GKE) Autopilot
C) Cloud Run
D) Compute Engine with custom machine types
Correct Answer: C
Rationale: Cloud Run is a fully managed serverless platform that
automatically scales from zero based on traffic and requires no
cluster management, minimizing operational overhead while
handling unpredictable traffic spikes. GKE Autopilot reduces
management overhead but still requires container orchestration
knowledge, and Compute Engine requires more operational
management .
,2. Your organization is planning a multi-region deployment for a
global e-commerce platform. The application must maintain
99.99% availability and withstand the failure of an entire region.
Which architectural approach should you recommend?
A) Single region with multiple availability zones
B) Active-passive with regional failover using Cloud DNS
C) Active-active with global load balancing and regional
redundancy
D) Single region with regional persistent disk replication
Correct Answer: C
Rationale: Active-active with global load balancing provides the
highest availability by serving traffic from multiple regions
simultaneously. Cloud Load Balancing distributes traffic across
regions with health checks, and if one region fails, traffic
automatically routes to healthy regions. Single region cannot
withstand region failure, and active-passive would have a higher
recovery time objective .
3. Your company needs to migrate 50 TB of on-premises data to
Google Cloud Storage. The migration must complete within 30
,days, and your network bandwidth is limited to 1 Gbps. Which
migration approach should you recommend?
A) gcloud storage cp with parallel composite uploads
B) Storage Transfer Service
C) Transfer Appliance
D) Cloud Storage with multi-threaded uploads
Correct Answer: C
Rationale: Transfer Appliance is a physical device that can
transfer up to 1 PB of data, bypassing network bandwidth
limitations. At 1 Gbps, transferring 50 TB would take
approximately 5 to 6 days at theoretical maximum, but in
practice with overhead, it could exceed the 30-day window.
Transfer Appliance provides a more reliable and faster option
for large data migrations .
4. You are designing a cloud architecture for a healthcare
application that must comply with HIPAA and store patient data
in the United States only. Which Google Cloud configuration
should you recommend?
A) Multi-region storage bucket with data residency in US
, B) Regional storage in us-central1 with organization policy
restricting resource locations
C) Global storage with data residency in US
D) Multi-region storage with default encryption
Correct Answer: B
Rationale: Regional storage in a specific US region combined
with an organization policy restricting resource locations
ensures data remains in the required jurisdiction. Multi-region
storage could replicate data outside the specified location, and
global storage does not provide location guarantees .
5. A machine learning team needs to train models on large
datasets. Training jobs run for hours and require GPUs. They
want to minimize cost while maintaining performance. What
compute solution should they use?
A) Persistent GPU VMs running continuously
B) Vertex AI Training with preemptible or spot VMs, or GKE with
spot node pools
C) Cloud Functions for ML training
D) Standard VMs without GPUs
