Analyze and optimize technical and business processes practice questions

This domain covers cost and performance optimization plus process automation on Google Cloud. Expect scenario questions on Dataflow, Pub/Sub, Cloud Storage classes, and Cloud Functions, where you pick the right service, storage tier, or ordered steps to cut spend, reduce shuffle, and implement disaster recovery.

Courseiva uses original exam-style practice questions designed for learning and revision. The goal is to understand the concepts, recognise exam patterns, and improve through explanations — not memorise copied exam dumps.

What the exam tests

What to know about Analyze and optimize technical and business processes

Be able to select the cheapest suitable storage class, tune Dataflow and Pub/Sub for lower shuffle and processing cost, and sequence Cloud Functions-based disaster recovery correctly. The key skill is matching access patterns and cost trade-offs to the right Google Cloud service.

Choosing Cloud Storage classes (Nearline, Coldline, Archive) by access frequency and retrieval tolerance

Reducing Dataflow streaming cost via right-sizing workers, autoscaling, and fewer shuffle operations

Ordering disaster recovery steps using Cloud Storage buckets and Cloud Functions triggers

Optimizing Pub/Sub ingestion and Dataflow windowing to lower processing and shuffle overhead

Watch out for

Common Analyze and optimize technical and business processes exam traps

  • ▸Picking Archive or Coldline for data needing frequent access, ignoring minimum storage durations and early-deletion fees.
  • ▸Assuming Dataflow autoscaling alone fixes shuffle cost, missing that pipeline design and key distribution drive it.
  • ▸Treating Cloud Functions disaster recovery steps as unordered, when the exam requires a specific correct sequence.

Question 8mediummultiple choice
Review the full routing breakdown →

You are a cloud architect for an e-commerce company. Their application runs on Google Kubernetes Engine (GKE) with a Regional cluster. The application consists of a frontend service, a backend service, and a Redis cache. Traffic is routed via an external HTTP(S) Load Balancer to the frontend. Recently, customers have reported intermittent 502 Bad Gateway errors during peak hours. The frontend logs show 'upstream connect error or disconnect/reset before headers. retried and limit reset' errors. The backend service is deployed with 3 replicas, each with resource requests of 1 CPU and 2 GB memory. The cluster autoscaler is enabled with a minimum of 3 nodes and a maximum of 10 nodes, using e2-standard-4 instances. The backend service's HPA is configured with CPU utilization target of 80%. During peak hours, CPU utilization on the backend pods reaches 90%, but the HPA does not scale up. The cluster has sufficient node capacity. What should you do to resolve the issue?
