Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
A blue environment running the old version
Why it's wrong here
Blue/green uses two environments; canary can use more than two, but a 'blue' environment isn't specifically required.
- ✗
A CI/CD pipeline with automated testing
Why it's wrong here
While helpful, it's not strictly essential for the canary strategy itself.
- ✗
An auto scaling group for the new version
Why it's wrong here
Auto scaling is not required for canary; manual scaling can work.
- ✓
A load balancer to distribute traffic between versions
Why this is correct
Needed to control traffic percentages.
- ✓
Monitoring to track error rates and performance
Why this is correct
Monitoring triggers automatic rollback if issues are detected.
