AWS Certified CloudOps Engineer Associate SOA-C03 Practice Question

An operations team manages a microservice that runs as an Amazon ECS service on AWS Fargate behind an Application Load Balancer. The team must deploy new container images with near-zero downtime, initially route only 10% of traffic to the new task set, and automatically roll back if a CloudWatch alarm triggers. Which deployment approach meets these requirements?

  • Use AWS CodeDeploy blue/green deployment for ECS with traffic shifting and CloudWatch-based automatic rollback.

  • Create a second target group and manually adjust Application Load Balancer listener rule weights with the AWS CLI.

  • Migrate the service to AWS Elastic Beanstalk and use the immutable deployment policy.

  • Update the ECS service with the rolling update deployment type and rely on the default minimumHealthyPercent setting.
