- Question 1Modernizing Infrastructure and Applications with Google Cloud
What is the difference between Compute Engine, GKE, App Engine, and Cloud Run?
Show Answer & Explanation
Correct Answer: BExplanation:Compute Engine: full VM control. GKE: managed K8s for container orchestration. App Engine: PaaS (standard=sandboxed, flex=containers). Cloud Run: serverless containers, auto-scale to zero. Choice depends on control needs and operational maturity.
- Question 2Infrastructure and Application Modernization
What is Google Anthos used for?
Show Answer & Explanation
Correct Answer: BExplanation:Anthos: multi-cloud/hybrid application platform. Run Kubernetes workloads consistently on GCP (GKE), on-premises (Anthos on VMware/bare metal), and other clouds (Anthos on AWS/Azure). Provides: unified management, service mesh (Anthos Service Mesh), config management, and policy enforcement.
- Question 3Infrastructure and Application Modernization
What is Google Kubernetes Engine (GKE)?
Show Answer & Explanation
Correct Answer: BExplanation:GKE: managed Kubernetes environment. Google handles the control plane, node upgrades, security patches, and monitoring. Supports Autopilot mode (fully managed nodes) and Standard mode (more control). Ideal for microservices architectures.
- Question 4Infrastructure and Application Modernization
What is Google Kubernetes Engine (GKE) used for?
Show Answer & Explanation
Correct Answer: BExplanation:GKE provides a managed Kubernetes environment for deploying, scaling, and managing containerized applications, handling cluster infrastructure, upgrades, and maintenance.
- Question 5Infrastructure and Application Modernization
What are the benefits of Cloud Run over GKE?
Show Answer & Explanation
Correct Answer: BExplanation:Cloud Run advantages: zero infrastructure management, scale to zero (cost savings), rapid deployments (seconds), any language/binary (container-based), and built-in HTTPS. GKE advantages: persistent workloads, custom scheduling, sidecars, service mesh, stateful sets, and DaemonSets. Choose Cloud Run for: stateless microservices, event-driven workloads. Choose GKE for: complex orchestration needs.
Key Infrastructure Concepts for CDL
CDL Infrastructure Exam Tips
Infrastructure and Application Modernization questions in CDL are typically scenario-based. Focus on service-level decision making aligned to official exam objectives. Priority concepts: compute engine, gke, cloud run, app engine, anthos, containers.
What CDL Expects
- Anchor your answer in select the most practical, secure, and scalable answer for the stated scenario.
- Infrastructure scenarios for CDL are frequently mapped to Domain 3 (~25%), so read the objective carefully before picking controls or architecture.
- Expect multi-service scenarios where Infrastructure interacts with IAM, networking, storage, or observability patterns rather than appearing as an isolated service question.
- When two options are both technically valid, prefer the choice that best aligns with the exam's operational scope (Foundational) and managed-service best practices.
High-Value Infrastructure Concepts
- Know the core Infrastructure building blocks cold: compute engine, gke, cloud run, app engine.
- Review the edge-case features and limits for anthos, containers; these details are commonly used to differentiate answer choices.
- Practice service-integration reasoning: how Infrastructure pairs with Digital Transformation, Security & Operations in real deployment patterns.
- For CDL, explain why the chosen Infrastructure design meets reliability, security, and cost expectations better than the alternatives.
Common CDL Traps
- Watch for answers that partially solve the requirement but miss operational constraints.
- Questions in Infrastructure and Application Modernization often include distractors that look correct for Infrastructure but violate least-privilege, durability, or availability requirements.
- Avoid picking options purely by feature name; validate data path, failure handling, and governance impact before answering.
- If the prompt hints at automation or repeatability, eliminate manual-only operational answers first.
Fast Review Checklist
- Can you compare at least two Infrastructure implementation paths and justify which one best fits the scenario?
- Can you map the chosen answer back to Infrastructure and Application Modernization (~25%) outcomes for CDL?
- Can you explain security and access boundaries for Infrastructure without relying on default-open assumptions?
- Can you describe how Infrastructure integrates with Digital Transformation and Security & Operations during failure, scaling, and monitoring events?
