SAA-C03 deep review — September 28, 2026

Read the complete guide, 189 knowledge/skill bullets across 14 tasks, root, service list and credential page. Broad objectives match the accepted baseline. Italian delivery retires after December 31, 2026; add the missing notice and mark delivery change scheduled while retaining the active certification.

Learning improvements

Explain MREC/MRSC consistency, witnesses, TTL/transaction restrictions and September 23 expansion to cross-continent combinations of supported Regions. Separate zero RPO from application RTO. Add regional NAT coverage/migration considerations, S3 Files synchronization, restricted LiveAnalytics/Snowball access, historical Elastic Transcoder shutdown and Requester Pays.

Repair the checkout database/event gap with an atomic outbox and retrying relay. Distinguish queue-age alarms from backlog-per-instance target tracking. Fill shared responsibility, API/container migration, analytical lake/governance, schema migration, hybrid compute and hibernation gaps. Preserve 42 original answers with corrected storage/scaling explanations.

Five original worked cases cover surviving AZ capacity, queue target, archive economics, eligible network savings and RPO/RTO. Nine arithmetic assertions passed. Eight labs remain proposed.

Selected reading and verification

The May 20 DynamoDB readiness article supplies replication/monitoring reasoning; current docs govern Region and feature support. The July 9 cost case supplies prioritization/staging ideas, not guaranteed savings or instant DNS rollback.

Pluralsight confirms 97 hours/12 courses/six labs. Dojo public descriptions were inspected with an explicit recalled-material boundary. O'Reilly/Udemy were blocked; Whizlabs/Skill Builder shells and video title metadata did not verify detailed counts/runtime. No paid lessons, blog code, AWS resources or failover drills were executed. Human review remains pending.

The operational receipt records hashed objectives, section mappings, evidence and repository/site checks. Accepted snapshots were preserved.
