1. What are the five pillars of the Well-Architected Framework?

C. The five pillars apply to every workload regardless of technology.

2. What does the WAF focus on, compared with the Cloud Adoption Framework?

D. CAF is organization-wide adoption; WAF guides the design of one workload.

3. Which pillar is about the workload meeting its commitments and recovering from failures?

B. Reliability = resiliency and availability against defined targets.

4. Which pillar is about confidentiality, integrity and availability of data and systems?

B. Security protects against threats using the CIA triad.

5. Which pillar covers DevOps practices, observability, automation and safe deployments?

B. Operational excellence is about how the workload is built, deployed and operated.

6. Which pillar is about a workload's ability to scale to meet demand efficiently?

B. Performance efficiency matches capacity to demand.

7. Which pillar is about getting the most value for money, not simply the lowest cost?

C. The goal is maximum return on investment, aligned with business requirements.

8. Why does the WAF talk about trade-offs?

B. Architects balance the pillars against business priorities.

9. Adding a second region improves reliability. Which pillar is most directly affected negatively?

C. Duplicated infrastructure costs money; operations also get more complex.

10. Which tool reviews a workload against the WAF pillars with a questionnaire and recommendations?

B. The assessment gives a score per pillar and links to guidance.

11. Which Azure service gives personalized recommendations aligned with the WAF pillars for deployed resources?

A. Advisor groups recommendations into reliability, security, performance, cost and operational excellence.

12. What are WAF service guides?

C. Service guides (e.g. for AKS, App Service) give pillar-by-pillar recommendations.

13. What's a design principle of all pillars?

D. Architecture is iterative; requirements and the platform change.

14. A design achieves 99.99% availability but the business only needs 99.9%. What does the WAF suggest?

D. Design to requirements; exceeding them costs money without business value.

15. Which pillar would "apply least privilege and Zero Trust" belong to?

B. Least privilege and Zero Trust are core security principles.

16. Which pillar would "use infrastructure as code" primarily belong to?

C. IaC enables consistent, repeatable deployments, an operational practice (with reliability benefits).

17. Which pillar would "autoscale based on load" primarily belong to?

A. Autoscaling matches capacity to demand (and helps cost).

18. Which pillar would "right-size underused VMs" primarily belong to?

B. Removing waste is cost optimization.

19. Which pillar would "define RTO and RPO for each flow" belong to?

A. Recovery targets are reliability requirements.

20. What are Azure Well-Architected workload guides (e.g. for SaaS, mission-critical, AI)?

C. Workload guides cover design areas and trade-offs typical for that workload type.

Part B

Design exercise

On paper · about 25 minutes

Copperleaf Books runs an online bookshop on a single VM with a SQL database on the same VM. Deployments are manual on Friday evenings. The site went down twice last quarter, and the monthly bill is higher than expected.

  1. Task

    Score the workload per pillar

    For each of the five pillars, write one weakness you see.

    Done when
    • Five pillars, five weaknesses.
    Model answer
    • Reliability: single VM, no redundancy, database on the same box.
    • Security: one machine holds everything, likely broad admin access, no WAF.
    • Cost: VM probably oversized for average load, no reservations.
    • Operational excellence: manual Friday deployments, no IaC, no monitoring.
    • Performance: can't scale out during sales.
  2. Task

    Propose one improvement per pillar and its trade-off

    For each weakness, propose a change and name the pillar it may hurt.

    Done when
    • Each proposal names a trade-off.
    Model answer
    • App Service across zones + Azure SQL Database (reliability, performance; cost up, partly offset by PaaS).
    • Front Door with WAF, managed identity, Key Vault (security; small cost).
    • Autoscale + reservations for the baseline (cost; commitment risk).
    • Bicep + pipeline + deployment slots (operations; time to build).
    • Application Insights + alerts (operations; ingestion cost).
