Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Blue/green deployment
Why it's wrong here
Blue/green switches all traffic at once; does not shift traffic gradually.

Rolling deployment
Why it's wrong here
Rolling replaces instances one by one but does not shift traffic percentages or provide automated rollback based on monitoring.
- ✗
Recreate deployment
Why it's wrong here
Recreate terminates all old pods before creating new ones, causing downtime.
- ✓
Canary deployment
Why this is correct
Canary gradually shifts traffic percentage, monitors, and can auto-rollback.
