What the exam tests

What to know about Manage implementation of cloud architecture

Cloud concepts questions usually test the service model (IaaS/PaaS/SaaS) and deployment model (public/private/hybrid/community) appropriate for a given scenario.

IaaS, PaaS and SaaS responsibilities and examples.

Public, private, hybrid and community cloud deployment models.

On-premises vs cloud trade-offs: cost, control, scalability.

How cloud connectivity options (VPN, Direct Connect, ExpressRoute) work.

Watch out for

Common Manage implementation of cloud architecture exam traps

  • ▸IaaS gives you infrastructure control; SaaS gives you only the application.
  • ▸Hybrid cloud combines on-premises and public cloud — not two public clouds.
  • ▸Cloud does not automatically mean cheaper or more secure.
  • ▸Management responsibility shifts with each service model (IaaS → PaaS → SaaS).

An organization has two Google Cloud projects: Project A hosts a Compute Engine instance with a MySQL database, and Project B hosts an application that needs to connect to the database. The network team set up VPC peering between the two VPCs. The application cannot connect to the database on port 3306. The database instance has a private IP. The network team has verified that firewall rules in both VPCs allow traffic from Project B's subnets to the database IP on port 3306. Ping from the application instance to the database IP succeeds. What should the architect do to resolve the connectivity issue?

Your company runs a critical application on Google Kubernetes Engine (GKE) in us-central1. The application consists of a frontend deployment with 3 replicas and a backend statefulset with 5 replicas using persistent volumes (SSD). Recently, the team noticed that during a regional outage in us-central1, the application became completely unavailable. They want to design a multi-region architecture that can survive a regional failure with RPO of 1 hour and RTO of 30 minutes. The application is stateless on the frontend but the backend stores critical data on persistent disks. The backend can operate in a read-only mode from a secondary region if needed. They have a limited budget and want to minimize ongoing costs. Which approach should they take?

Your company runs a containerized microservices application on Google Kubernetes Engine (GKE) with a regional cluster. The application consists of a frontend service, a backend API service, and a background worker service that processes messages from Cloud Pub/Sub. The worker service uses a Deployment with 3 replicas. Recently, the team noticed that the worker service is frequently failing with 'ContainerCreating' errors. The error message in the pod events is: 'Failed to pull image "gcr.io/my-project/my-worker:latest": rpc error: code = DeadlineExceeded desc = context deadline exceeded'. The image is stored in Container Registry in the same project. The cluster nodes are n1-standard-2 VMs with 10 GB of disk space. The team has confirmed that the image exists and that the nodes have internet access. What is the most likely cause of the issue?
