Sample Questions — Google Cloud Professional Cloud Architect (PCA)

5 free sample questions from this practice exam. Correct answers are highlighted.

1. A retail company is migrating its e-commerce platform to Google Cloud. The business requires 99.99% availability during peak shopping seasons and must ensure that a regional outage does not impact customer transactions. Which architecture best meets these requirements?

A Deploy the application across multiple regions using Cloud Spanner as the database and a global HTTP(S) Load Balancer to route traffic. ✓ Correct
B Deploy the application in a single region across multiple zones using Cloud SQL with automatic failover replicas.
C Deploy the application in a single region using Cloud SQL with cross-region read replicas and promote them manually during an outage.
D Deploy the application in a primary Google Cloud region and maintain an on-premises data center as a warm standby for regional failover.

2. A healthcare company needs a globally distributed, strongly consistent relational database for a patient record system that must handle millions of writes per second across multiple regions. Which database service should the architect choose?

A Use Cloud SQL for PostgreSQL with cross-region read replicas to distribute the load globally.
B Use Cloud Spanner with a multi-region instance configuration. ✓ Correct
C Use Cloud Bigtable with a multi-cluster replication configuration.
D Use AlloyDB for PostgreSQL with AlloyDB Omni deployed in multiple regions.

3. A company is executing a large-scale migration of 200 applications to Google Cloud. During the dependency mapping phase using Migration Center, the architect discovers that Application A has 45 downstream dependencies, including 8 applications that are being considered for deprecation. Migrating Application A without the deprecated applications would require significant re-engineering. What should the architect recommend for handling this dependency complexity in the migration plan?

A Migrate Application A to Google Cloud immediately and update its configuration to skip calls to the 8 deprecated applications, accepting potential functionality gaps.
B Use the dependency analysis to inform migration wave planning: either accelerate the deprecation of the 8 applications before migrating Application A, or include all critical dependencies in the same migration wave, resolving the deprecation status first. ✓ Correct
C Place all 45 dependent applications (including the 8 to be deprecated) in the same migration wave as Application A to ensure all dependencies are available post-migration.
D Exclude Application A and all 45 dependent applications from the migration plan entirely due to the complexity of the dependency graph.

4. A company is deploying a new application on Google Cloud and needs to connect its on-premises data center to its VPC network with a guaranteed SLA and dedicated bandwidth of 10 Gbps. The connection must support private communication without traffic traversing the public internet. Which hybrid networking solution should the architect recommend?

A Provision a Dedicated Interconnect connection between the on-premises router and a Google Cloud colocation facility. ✓ Correct
B Configure a High Availability Cloud VPN gateway with two tunnels to the on-premises VPN gateway.
C Use Partner Interconnect through a supported service provider to establish a 10 Gbps VLAN attachment.
D Deploy Cloud NAT in the VPC to allow on-premises systems to reach Google Cloud services.

5. A company is setting up its Google Cloud environment for the first time. The security team wants to enforce guardrails across all projects and folders from a single point of control. Which Google Cloud construct should a cloud architect use as the root of the resource hierarchy?

A Create an Organization node tied to the company's Cloud Identity domain and apply policies at that level. ✓ Correct
B Create a top-level folder named 'root' and apply policies to it.
C Create a single host project and use it to manage all other projects.
D Link all projects to a single billing account and apply policies there.
