Exam Professional Cloud Developer topic 1 question 320 discussion

Omiting A & D directly, option B looks more simpler than C , option C says more about not providing traffic directly but later splits the traffic, based on this im going with B

Backward Compatibility: By deploying the new revision with no traffic allocated initially, you ensure that existing clients continue to receive responses from the current service without any disruptions. This approach preserves backward compatibility, allowing clients that rely on the previous response structure to continue functioning. Traffic Splitting: After deploying the new revision, you can then proceed to split the traffic between the current service and the new revision. In this case, directing 10% of the traffic to the new revision allows you to test the changes with a subset of users while monitoring for any issues.
