KCNA Cloud Native Architecture Practice Question
Which CNCF project maturity level indicates that a project has successfully adopted the CNCF governance and is considered stable for production use?
⚠ Common exam trap
CNCF often tests the distinction between Sandbox and Incubating, where candidates mistakenly think Sandbox implies production readiness, but Sandbox is explicitly for early-stage projects that have not yet demonstrated stability or adopted full CNCF governance.

Correct answer & explanation
✓
Graduated
The Graduated maturity level is the highest in the CNCF project lifecycle, indicating that a project has both successfully adopted CNCF governance and is considered stable for production use. To achieve Graduated, a project must meet rigorous criteria including adoption by multiple end users, a defined governance structure, and completion of a security audit. This distinguishes it from lower maturity levels such as Sandbox (early-stage) and Incubating (growing but not yet stable).
