Which two practices are essential for securing a CI/CD pipeline? (Choose two.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Implement code signing for all build artifacts.
Options B and C are correct. Code signing ensures artifact integrity, and vulnerability scanning prevents deploying insecure images. Option A is insecure. Option D lacks necessary review. Option E is beneficial but not as essential as B and C.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Real-world example
How this comes up in practice
A practitioner preparing for the CAS-004 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
