Answer options:
A.
CodeDeploy with an Immutable deployment configuration.
B.
CodeDeploy with a Canary deployment configuration.
C.
CodeDeploy with a Linear deployment configuration.
D.
CodeDeploy with a Blue/Green deployment configuration.
How to approach this question
Distinguish between Canary (one initial shift, then the rest) and Linear (step-by-step increments).
Full Answer
C.CodeDeploy with a Linear deployment configuration.✓ Correct
CodeDeploy with a Canary deployment configuration.
A Linear deployment shifts traffic in equal increments with an equal number of minutes between each increment (e.g., 10% every 5 minutes). A Canary deployment shifts a percentage once, waits, and then shifts the remaining 100%.
Common mistakes
Confusing Canary (two steps) with Linear (multiple equal steps).
