Cloud Concepts answer key

  1. A — IaaS. It preserves control of the guest OS and supports lift-and-shift scenarios.
  2. B — PaaS. The provider manages the OS and platform while developers focus on the application.
  3. C — SaaS. The requirement is a complete, ready-to-use application.
  4. C — Scale up. The size of one existing resource increases.
  5. A — Scale out. The number of instances increases.
  6. C — Hybrid. The solution combines connected on-premises and public-cloud resources.
  7. B — The customer. The customer remains responsible for identities, access decisions, and organizational data.
  8. A — Within the same region. Zones provide physical separation and independent infrastructure inside a region.
  9. C — No. Region pairing does not automatically replicate every resource.
  10. C — Management group. It provides a scope above subscriptions for governance at scale.
  11. B — No. A resource belongs to one resource group at a time.
  12. A. The tenant is the identity directory; the subscription is a management, billing, quota, and resource boundary.
  13. B — Elasticity. Capacity follows temporary demand, often automatically.
  14. C. Deleting the group deletes its resources. The resources can use different regions, and groups cannot be nested.
  15. A — Azure Functions/serverless. Event-driven execution without server administration is the key clue.
  16. A — Measured service. Cloud providers meter consumption using units appropriate to each service. The meter is not necessarily the same for every service.
  17. A — Private cloud. It is dedicated to one organization while still providing cloud characteristics such as self-service and automation.
  18. A — CapEx. Physical assets purchased upfront are capital expenditure. Ongoing service consumption is commonly associated with OpEx.
  19. A — Disaster recovery. Cross-region recovery addresses a regional disaster. High availability usually focuses on minimizing interruption during ordinary/local failures.
  20. A — Microsoft. App Service is PaaS, so Microsoft operates and patches the underlying OS and managed runtime platform.
  21. A — The customer. SaaS transfers application operation to the provider, but the customer still manages identities, sharing, access decisions, and organizational data.
  22. A. A zonal VM resides in one selected zone. Resilience requires additional instances across zones or a zone-redundant service design.
  23. A. Region selection balances legal requirements, service/SKU availability, latency, resilience features, capacity, and cost.
  24. A — Management group. It provides governance scope above subscriptions. Assignments can flow to subscriptions and resources below it.
  25. A. The resource group's region stores its metadata. Resources inside the group can be deployed to other supported regions.

Score guide

  • 22–25: Strong. Explain every wrong option before moving on.
  • 18–21: Good foundation. Review the comparisons behind missed questions.
  • 13–17: Revisit the relevant full lessons, then try new scenarios.
  • 0–12: Study the concept pages again before relying on the cheat sheet.

A score from a repeated quiz can measure memory rather than understanding. Use different practice sets and explain the distractors aloud.
