An architect needs to roll out a Lambda function update across many regions with progressive traffic shift and CloudWatch-alarm-based rollback. Which DOP-C02 service combination fits?
AAWS Snowball
BAmazon RDS
CManual `aws lambda update-function-code` in every region
DLambda versions + aliases + CodeDeploy traffic-shifting with linked CloudWatch alarms
Answer & Solution
Correct answer: D. Lambda versions + aliases + CodeDeploy traffic-shifting with linked CloudWatch alarms
Lambda aliases + CodeDeploy traffic shifting + alarm-gated rollback is the canonical Lambda progressive-deploy pattern (per DOP-C02 §1.4). Manual updates lack rollback; the others aren't deploy tools.
