Study Notes

Google Cloud Practice Test Highlights

Google Account Access Management: Grant the compute.osAdminLogin role to Google group members for SSH access, allowing individual public key management.
Custom VPC Creation: Use Deployment Manager to create a custom VPC with a single large subnet, adhering to Google's best practices.
Kubernetes Deployment: Deploy a Dockerfile by creating a Docker image, uploading it to Container Registry, and using a Deployment YAML file along with kubectl.
Jenkins Server Deployment: Simplest deployment of Jenkins server is through GCP Marketplace, enabling quick setup with minimal steps.
Deployment Manager Updates: To avoid downtime, use the specific command for rolling updates in Deployment Manager.
App Engine Deployment Analysis: For deployment issues, check Google Cloud configuration with the gcloud config list command in Cloud Shell.
Compute Engine Instance Configuration: For high availability with automatic restart during maintenance, use instance groups with Autohealing health checks configured.
Service Account Communication: Establish TCP communication between different tiers in Compute Engine through specific ingress firewall rules targeting service accounts.
Cloud Run and Pub/Sub Integration: For Cloud Run applications processing Pub/Sub messages, grant the service account the Cloud Run Invoker role and create a subscription that uses this service account as the push endpoint.
Cost-Effective Application Deployment: For minimal cost applications with low HTTP request traffic, deploy on Cloud Run instead of GKE or App Engine Flexible.
