What certification to take next
The exam costs $200 USD. Prices may vary slightly by country.
Google does not publish a specific numerical passing score. Results are reported as Pass or Fail after exam delivery.
It is considered one of the hardest Google Cloud exams (rated 5/5). It tests deep architectural judgment across security, reliability, cost, and compliance — often using scenario-based case studies.
The exam typically contains 50-60 questions, including multiple choice and multiple select questions, some tied to case study scenarios.
It tests your ability to design secure, scalable, highly available Google Cloud solutions covering compute, storage, networking, databases, security, and cost optimisation.
The certification is valid for 3 years. You must recertify by retaking the exam before expiry.
Solutions architects, cloud engineers, and technical leads with at least 1 year of Google Cloud design experience who want to demonstrate senior-level cloud architecture skills.

Term reference
These terms appear frequently in Google PCA questions. Understanding them precisely reduces guessing and improves scores.
File Transfer Protocol
File Transfer Protocol (FTP) is a standard network protocol used to transfer files between a client and a server over a TCP/IP network.
Public IP address
A globally unique IP address assigned to a device that allows it to communicate directly over the internet.
Persistent Disk
Persistent Disk is a durable, high-performance block storage service for Google Cloud virtual machines that retains data even after the VM is shut down or deleted.
Sole-tenant node
A physical Compute Engine server that is dedicated solely to your project, ensuring that no other customer's virtual machines (VMs) run on that same hardware.
EBS encryption
EBS encryption is a security feature that automatically encrypts data stored on Amazon Elastic Block Store volumes, protecting it at rest and in transit between the volume and the attached EC2 instance.
Structured data
Structured data is information that is organized in a predefined format, typically in rows and columns, making it easy to search, process, and analyze by computers.
Common Criteria
Common Criteria is an international standard (ISO 15408) that provides a common framework for evaluating the security features and capabilities of information technology products.
SFTP
SFTP (SSH File Transfer Protocol) is a secure method for transferring files over a network using an encrypted SSH connection.

Sample questions
Select your answer before revealing the explanation. These questions are original exam-style — not copied from any exam or dump site.
Trap 1: Pricing differences between regions due to variations in compute…
Cost is a factor but not among the top three when low latency is critical.
Trap 2: Number of zones in the region to ensure high availability.
Most regions have three zones; difference is minimal.
Proximity to your user base to minimize network latency.
Closer regions reduce round-trip time.
Availability of the specific Google Cloud services required by the application.
Not all services are in all regions.
Pricing differences between regions due to variations in compute and storage costs.
Why wrong: Cost is a factor but not among the top three when low latency is critical.
Compliance with data residency requirements (e.g., GDPR, CCPA).
Data must stay within specific geographic boundaries.
Number of zones in the region to ensure high availability.
Why wrong: Most regions have three zones; difference is minimal.
Trap 1: Set the log bucket retention to 7 years
Log retention in Cloud Logging incurs costs and is more expensive than Cloud Storage.
Trap 2: Export logs to BigQuery and run scheduled queries to delete old data
BigQuery storage and queries are more costly for long-term archival.
Trap 3: Use Cloud Logging's default retention and rely on backups
Default retention is 30 days, insufficient for 7 years.
Set the log bucket retention to 7 years
Why wrong: Log retention in Cloud Logging incurs costs and is more expensive than Cloud Storage.
Export logs to Cloud Storage with Object Lifecycle management to delete after 7 years
Cloud Storage is cost-effective for long-term retention with lifecycle rules.
Export logs to BigQuery and run scheduled queries to delete old data
Why wrong: BigQuery storage and queries are more costly for long-term archival.
Use Cloud Logging's default retention and rely on backups
Why wrong: Default retention is 30 days, insufficient for 7 years.

Requires code changes and Cloud Spanner is not MySQL-compatible.
Use a managed instance group for the application VM and store the database on a persistent disk attached to the primary instance.
Why wrong: The database is still a single point of failure unless you manually configure replication.
Re-architect the application into microservices and use Cloud Run for stateless components.
Why wrong: This requires significant code changes and is not minimal effort.
Lift and shift the VM to Compute Engine, and migrate the database to Cloud SQL with a failover replica.
Minimal code changes, uses managed database with high availability.
Containerize the application and deploy on Google Kubernetes Engine (GKE) with Cloud Spanner as the database.
Why wrong: Requires code changes and Cloud Spanner is not MySQL-compatible.
Trap 1: Configure client-side encryption in the application code
Client-side encryption is not a recommended architecture pattern for Cloud SQL and would add complexity.
Trap 2: Rely on Google-managed default encryption for all data
Default encryption does not meet PCI DSS requirements for key management control.
Trap 3: Use Cloud HSM with a key generated outside of Google Cloud
Cloud HSM is a key management service, but the question asks for actions specifically for encryption at rest and in transit; CMEK already covers this.

Why wrong: Client-side encryption is not a recommended architecture pattern for Cloud SQL and would add complexity.
Rely on Google-managed default encryption for all data
Why wrong: Default encryption does not meet PCI DSS requirements for key management control.
Enable customer-managed encryption keys (CMEK) on Cloud SQL and Cloud Storage
CMEK provides control over key management required for PCI DSS.

VPC Service Controls prevent data exfiltration and help meet compliance.
Use Cloud HSM with a key generated outside of Google Cloud
Why wrong: Cloud HSM is a key management service, but the question asks for actions specifically for encryption at rest and in transit; CMEK already covers this.
Trap 1: Secret Manager
Secret Manager stores secrets, not key lifecycle management.
Trap 2: Cloud External Key Manager (Cloud EKM)
Cloud EKM is for managing keys outside Google Cloud.
Trap 3: Cloud Hardware Security Module (Cloud HSM)
Cloud HSM provides hardware-backed keys but management is still done via Cloud KMS.
