KCNA Cloud Native Architecture Practice Question
Which CNCF project maturity level indicates that a project has adopted the CNCF Code of Conduct and is considered early-stage?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Sandbox
The CNCF has three maturity levels: sandbox (early-stage), incubating (growing), and graduated (mature). Sandbox projects are early-stage and have accepted the CNCF Code of Conduct.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Sandbox
Why this is correct
Sandbox is the earliest CNCF maturity level. Projects at this stage must adopt the CNCF Code of Conduct and are described as early-stage experiments, before progressing to Incubating and then Graduated. It directly matches the stem's requirement for the level indicating Code of Conduct adoption and early-stage status.
- ✗
Incubating
Why it's wrong here
Incubating is a later stage than the one described: projects there have demonstrated adoption and healthy governance, not merely Code of Conduct adherence. It tempts because it is genuinely early relative to Graduated, yet Sandbox is the entry level matching the stem's criteria.
- ✗
Graduated
Why it's wrong here
Graduated denotes the highest maturity tier, requiring broad production adoption, a security audit and a governing board, so it cannot indicate an early-stage project. It tempts as the best-known CNCF label, but Sandbox is the level tied to Code of Conduct adoption.
- ✗
Experimental
Why it's wrong here
Experimental is not a CNCF maturity level; the sanctioned stages are Sandbox, Incubating and Graduated. The term describes pre-CNCF or vendor-hosted projects, which is why it tempts, but Sandbox is the stage that requires Code of Conduct adoption for early-stage projects.
