Selected Answer: D
his method involves deploying the new version of your application alongside the old version (two separate but identical environments: blue for the old version and green for the new one). You then switch traffic from blue to green. If any issues arise with the green environment (the new version), you can instantly route traffic back to the blue environment (the old version). This approach offers the fastest rollback mechanism as it merely involves a change in the traffic routing.
