SOA-C03 deep review — September 28, 2026

Read the complete guide, all 53 numbered skills across 13 tasks, root/in-scope pages and June 1 revision 1.1. Broad objectives match the accepted snapshot. Simplified Chinese/Korean delivery still retires after November 19; no additional overall exam retirement was found. The old-version comparison endpoint returned title-only content, so current root/revision pages support the transition account.

Learning changes

Add AI monitoring that distinguishes API success from useful answers and explains Bedrock metric denominators/retries. Specify composite-alarm action limits. Explain current Kiro, DevOps Agent and Security Agent/Continuum purposes and access boundaries. Recognize Database Insights at the old Performance Insights documentation path, X-Ray instrumentation maintenance and regional NAT behavior.

Expand S3 Files with versioning, delayed export, conflict handling, lost-and-found and per-object rename implications. The April 7 launch article is useful with current synchronization documentation; its demo was not executed and broad performance/zero-tradeoff claims were not adopted.

Four original worked checks cover alarms, a configured worker ceiling, full RTO/RPO evidence and file-export timing. Eight local assertions passed. Retain 40 original answers and add five for the new material. All eight cloud labs remain proposed.

Sources and limits

Pluralsight confirms 17 hours/five courses/four labs. Tutorials Dojo publicly lists 13.8+ video hours and practice modes; paid completeness is unverified, and actual-exam feedback marketing requires avoiding recalled material. O'Reilly/Udemy were blocked; Whizlabs/Skill Builder shells did not support detailed catalog claims. Kiro's purpose was checked through separately rendered documentation.

No AWS resource, paid course, agent, live model or recovery drill was executed. Independent human review remains pending. The operational receipt records objective hashes, mappings, sources and repository/site checks. Accepted snapshots were preserved.
