65 questions · 130 minBuild practical AWS skills in an original local training account. Use service pages and familiar CLI command shapes to configure identity, storage, compute, networking, serverless workflows, data services, and monitoring. Continue into connected projects, incident cases, architecture decisions, and cloud interviews. Five original full-length practice forms follow the published Cloud Practitioner CLF-C02 guide and Solutions Architect Associate SAA-C03 guide. Practice results are independent learning feedback, not official scaled scores. All resources stay local; numeric rates are explicitly labeled fictional exercise inputs.
Interview practice
Explain what you've learned in a full-screen interview. Speak or type, then review your answers against the rubric for your level.
Interview loops by jobBeginner
Cloud foundations
Establish account context, cloud responsibilities, and reliable CLI habits.
Identity and access
Create identities and scope the permissions they need.
Object storage
Store, retain, and protect objects without confusing access and encryption.
Intermediate
Compute and disks
Choose compute, preserve disks, and configure a two-zone web platform.
Network paths
Trace routes and filters, then repair a private database connection.
Event services
Test functions, connect API routes, and buffer independent work.
Advanced
Data services
Design data access and recovery, then build a governed records lake.
Operations and delivery
Use monitoring, templates, and DNS evidence to explain operational behavior.
Security analysis
Evaluate permission boundaries and investigate denied reads and public exposure.
Expert
Architecture
Balance failure domains, asynchronous work, and migration requirements.
Economics and diagnosis
Calculate labeled example costs and make evidence-based technical recommendations.
Interviews and certification
Explain cloud decisions and practice five independent full-length exam forms.
