Your company’s DevOps team is in charge of deploying a large number of Lambda functions with AWS CodeDeploy service. The team has already created new applications in CodeDeploy. Then relevant deployment groups are being set up which include configurations used during the deployment. For the deployment configurations, which ways are supported?

Answer options:

A.CodeDeployDefault.LambdaAllAtOnce (Shifts all traffic to the new Lambda functions at once)
B.CodeDeployDefault.Immutable (Shifts the traffic to the new Lambda functions by performing an immutable update)
C.CodeDeployDefault.LambdaLinear10PercentEvery10Minutes (Shifts 10 percent of traffic every 10 minutes)
D.CodeDeployDefault.LambdaHalf (Shifts half traffic to the new Lambda functions and then shifts the other half)
E.CodeDeployDefault.AllAtATime ( Deploys the new version to all Lambda functions at a time )
F.CodeDeployDefault.LambdaCanary10Percent5Minutes (Shifts 10 percent of traffic in the first increment. The remaining 90 percent is deployed five minutes later)

Correct Answer – A, C, F
When the Deployment Group of AWS CodeDeploy is created, users need to configure the rules that determine how fast an application will be deployed, which is also called the “Deployment Configuration”:
About the supported deployment configurations for Lambda functions, refer to https://docs.aws.amazon.com/codedeploy/latest/userguide/deployment-configurations.html for details.
Option A is CORRECT: Because LambdaAllAtOnce is a supported configuration that shifts all traffic at a time.
Option B is incorrect: Because there is no Immutable configuration for Lambda.
Option C is CORRECT: Because the Linear method is supported for Lambda according to the above link.
Option D is incorrect: Because LambdaHalf is not supported. However, the Half mode is a supported configuration for the EC2/On-Premises Compute Platform.
Option E is incorrect: Because there is no AllAtATime mode for the Lambda function, according to the below link.
Please refer to page 283 on the below link

Option F is CORRECT: Because Canary is a supported mode that shifts 10% at first and then shifts the remaining items.
