You are designing a new insurance claims processing application that will be deployed on Google Kubernetes Engine (GKE) Your company’s compliance team requires a complete and non-repudiable audit trail for all administrative actions from day one. Your application must capture who deploys a new container image, who modifies the GKE cluster's configuration, and who interacts with running pods or Kubernetes secrets using kubectl.
What should you do?

  1. Enable Binary Authorization on the GKE cluster, and create a policy that requires all deployed container images to be signed by a trusted attestor.
  2. Deploy a DaemonSet to every node in the GKE cluster that runs a logging agent to collect and forward all container logs to Cloud Logging.
  3. Enable GKE Audit Logging to send Kubernetes API server logs to Cloud Logging, and ensure Cloud Audit Logs are enabled for the project.
  4. Activate the Security Command Center Premium tier to analyze GKE logs and detect threats, vulnerabilities, and misconfigurations in real time.

Answer(s): C

Explanation:

Enable GKE Audit Logging to send Kubernetes API server logs to Cloud Logging, and ensure Cloud Audit Logs are enabled for the project.
Reasoning
Comprehensive Coverage: GKE Audit Logs record all interactions with the Kubernetes API server. This includes:
Deployments: Captures who creates or updates deployments (deploys new container images).
Cluster Modifications: Records changes to cluster configuration via the API.
kubectl Interactions: Every command executed via kubectl (e.g., kubectl exec into pods or kubectl get secrets) generates an audit entry.



Your product team is building a critical, customer-facing application on Google Cloud. The development team wants to use Spanner for their database to take advantage of its horizontal scalability and low operational overhead However, the FinOps team is concerned about the direct monthly cost of Spanner and proposed using a self-managed PostgreSQL database on Compute Engine VMs instead. You need to resolve this conflict and ensure the project moves forward with an architecturally sound database choice that balances technical requirements with financial constraints.
What should you do?

  1. Provide the development team with a reference architecture for deploying a highly available PostgreSQL cluster on a regional managed instance group (MIG).
  2. Suggest using Cloud SQL for PostgreSQL as a compromise to get a managed service at a lower cost than Spanner.
  3. Develop a total cost of ownership (TCO) analysis that includes operational overhead, and present it in a workshop to facilitate a decision.
  4. Cite the reliability and performance optimization pillars of the Google Cloud Well-Architected Framework to formally justify the use of Spanner.

Answer(s): C

Explanation:

C: Develop a total cost of ownership (TCO) analysis that includes operational overhead, and present it in a workshop to facilitate a decision.
Total Cost of Ownership (TCO) vs. Direct Cost: The FinOps team is concerned about "direct monthly cost" (the raw line items on a bill). However, a true architectural decision must account for "operational overhead," which includes the labor costs of managing a database (patching, backups, high availability setup), the cost of potential downtime, and the technical debt of self-managed systems.
Data-Driven Decision Making: Developing a TCO analysis provides a quantitative, evidence-based foundation for a decision, rather than just citing abstract frameworks.
Stakeholder Alignment: Presenting this analysis in a workshop ensures that both the technical (development) and financial (FinOps) teams are aligned on the trade-offs between managed services (like Spanner) and self-managed options.



You are deploying a critical application with a stateless, containerized frontend on Cloud Run and a Cloud SQL for PostgreSQL backend. The application experiences unpredictable traffic spikes, and the business requires the ability to immediately roll back a failed deployment to the last known good state. You need to apply a deployment strategy that aligns with Site Reliability Engineering (SRE) principles for both the application code and the database schema updates, while meeting the business's requirements.
What should you do?

  1. Package the database schema migration script within the container to be executed on every container startup before the application process begins.
  2. Configure the CI/CD pipeline to use the :latest container tag for deployments, with database schema changes applied manually as needed.
  3. Separate CI/CD pipelines for database schema migrations from application deployments.
    When deploying a new Cloud Run revision, use gradual traffic split.
  4. Use a single CI/CD pipeline that first applies database schema changes and then deploys the new Cloud Run revision.

Answer(s): C

Explanation:

C: Separate CI/CD pipelines for database schema migrations from application deployments.
When deploying a new Cloud Run revision, use gradual traffic split.
SRE Principles and Requirements
Ability to immediately roll back: This is a key SRE requirement for reliability and a business need. Rolling back application code is straightforward with Cloud Run's revision system and traffic splitting. However, rolling back a database schema can be complex, error-prone, and slow, potentially violating the "immediate" rollback requirement.
Unpredictable traffic spikes: Cloud Run's serverless nature and automatic scaling handle this effectively.
Stateless, containerized frontend: This is an ideal architecture for Cloud Run and flexible deployment strategies.

For this question, refer to the Altostrat Media case study. Altostrat stores a large library of media content, including sensitive interviews and documentaries, in Cloud Storage. They are concerned about the confidentiality of this content and want to protect it from unauthorized access. You need to implement a Google-recommended solution that is easy to integrate and provides Altostrat with control and auditability of the encryption keys.
What should you do?

  1. Configure Cloud Storage to use server-side encryption with Google-managed encryption keys. Create a bucket policy to restrict access to only authorized Google groups and required service accounts.
  2. Use Cloud Storage default encryption at rest. Implement fine-grained access control using IAM roles and groups to restrict access to sensitive buckets
  3. Implement client-side encryption before uploading it to Cloud Storage. Store the encryption keys in a HashiCorp Vault instance deployed on Google Kubernetes Engine (GKE). Implement fine-grained access control to sensitive Cloud Storage buckets using IAM roles.
  4. Use customer-managed encryption keys (CMEK) for all Cloud Storage buckets storing sensitive media content. Implement fine-grained access control using IAM roles and groups to restrict access to sensitive buckets.

For this question, refer to the Altostrat Media case study. Altostrat is experiencing fluctuating computational demands for its batch processing jobs. These jobs are not time-critical and can tolerate occasional interruptions. You want to optimize cloud costs and address batch processing needs.
What should you do?

  1. Configure reserved VM instances
  2. Deploy spot VM instances.
  3. Set up standard VM instances.
  4. Use Cloud Run functions.

Answer(s): B

Explanation:

Answer(s): Deploy spot VM instances (Option B).
Cost-optimized compute: Spot VMs run on spare capacity at up to 80 % discount compared with on-demand pricing, which directly addresses Altostrat’s goal of reducing cloud spend for non-time-critical batch workloads. Interruption tolerance: Batch jobs can be checkpointed or restarted, so occasional pre-emptions do not affect overall throughput. Scalable capacity: Spot pools can be sized to match fluctuating demand, allowing Altostrat to scale out during peak processing windows and scale back when demand drops, improving resource utilization. Integration with existing GKE/CI-CD: Spot VMs can be used as node pools in GKE or as standalone Compute Engine resources, fitting naturally into the current containerized deployment pipeline without requiring new services.
Why the other options are less suitable
A – Reserved VM instances: Provide a lower unit price only when committing to 1- or 3-year usage. They are best for steady, predictable workloads; they do not accommodate the variable, interruptible nature of batch jobs and would lock Altostrat into over-provisioned capacity. C – Standard VM instances: Charge full on-demand rates and do not leverage spare capacity, leading to higher costs for workloads that could tolerate interruptions. D – Cloud Run functions: Are designed for event-driven, short-lived stateless requests, not for large-scale, CPU-intensive batch processing that benefits from persistent VM resources and custom runtime environments.
