Passleader 的dump,感觉答案不靠谱的太多,比如以下这个
NEW QUESTION 654
A company built an application based on AWS Lambda deployed in an AWS CloudFormation stack. The last production release of the web application introduced an issue that resulted in an outage lasting several minutes. A solutions architect must adjust the deployment process to support a canary release. Which solution will meet these requirements?
A. Create an alias for every new deployed version of the Lambda function.
Use the AWS CLI update-alias command with the routing-config parameter to distribute the load.
B. Deploy the application into a new CloudFormation stack.
Use an Amazon Route 53 weighted routing policy to distribute the load.
C. Create a version for every new deployed Lambda function.
Use the AWS CLI update-function- configuration command with the routing-config parameter to distribute the load.
D. Configure AWS CodeDeploy and use CodeDeployDefault.OneAtATime in the Deployment configuration to distribute the load.
Answer: C

我觉得答案应该是A, https://aws.amazon.com/blogs/compute/implementing-canary-deployments-of-aws-lambda-functions-with-alias-traffic-shifting/
通篇讲的都是如何用alias实现canary

NEW QUESTION 652
A company is manually deploying its application to production and wants to move to a more mature deployment pattern. The company has asked a solutions architect to design a solution that leverages its current Chef tools and knowledge. The application must be deployed to a staging environment for testing and verification before being deployed to production. Any new deployment must be rolled back in 5 minutes if errors are discovered after a deployment. Which AWS service and deployment pattern should the solutions architect use to meet these requirements?
A. Use AWS Elastic Beanstalk and deploy the application using a rolling update deployment strategy.
B. Use AWS CodePipeline and deploy the application using a rolling update deployment strategy.
C. Use AWS CodeBuild and deploy the application using a canary deployment strategy.
D. Use AWS OpsWorks and deploy the application using a blue/green deployment strategy.
Answer: A


这个应该是D吧,要用chef兼容模式就只能是opsworks

Q19. During a review of business applications, a Solutions Architect identifies a critical application with a relational database that was built by a business user and is running on the user's desktop. To reduce the risk of a business interruption, the Solutions Architect wants to migrate the application to a highly available, multi-tiered solution in AWS.
What should the Solutions Architect do to accomplish this with the LEAST amount of disruption to the business?

A. Create an import package of the application code for upload to AWS Lambda, and include a function to create another Lambda function to migrate data into an Amazon RDS database
B. Create an image of the user's desktop, migrate it to Amazon EC2 using VM Import, and place the EC2 instance in an Auto Scaling group
C. Pre-stage new Amazon EC2 instances running the application code on AWS behind an Application Load Balancer and an Amazon RDS Multi-AZ DB instance
D. Use AWS DMS to migrate the backend database to an Amazon RDS Multi-AZ DB instance.
Migrate the application code to AWS Elastic Beanstalk

Answer: D


这个我觉得是C.目标是追求最小的影响,应该用alb慢慢转移流量
