Question # 1

A company has a mission-critical application on AWS that uses automatic scaling Thecompany wants the deployment lilecycle to meet the following parameters.• The application must be deployed one instance at a time to ensure the remaining fleetcontinues to serve traffic• The application is CPU intensive and must be closely monitored• The deployment must automatically roll back if the CPU utilization of the deploymentinstance exceeds 85%. Which solution will meet these requirements?

Question # 2

A company has 20 service learns Each service team is responsible for its ownmicroservice. Each service team uses a separate AWS account for its microservice and aVPC with the 192 168 0 0/22 CIDR block. The company manages the AWS accounts withAWS Organizations.Each service team hosts its microservice on multiple Amazon EC2 instances behind anApplication Load Balancer. The microservices communicate with each other across thepublic internet.

A. Create a new AWS account in AWS Organizations Create a VPC in this account anduse AWS Resource Access Manager to share the private subnets of this VPC with theorganization Instruct the service teams to launch a new. Network Load Balancer (NLB) and EC2 instances that use the shared private subnets Use the NLB DNS names forcommunication between microservices.
B. Create a Network Load Balancer (NLB) in each of the microservice VPCs Use AWSPrivateLink to create VPC endpoints in each AWS account for the NLBs Createsubscriptions to each VPC endpoint in each of the other AWS accounts Use the VPCendpoint DNS names for communication between microservices.
C. Create a Network Load Balancer (NLB) in each of the microservice VPCs Create VPCpeering connections between each of the microservice VPCs Update the route tables foreach VPC to use the peering links Use the NLB DNS names for communication betweenmicroservices.
D. Create a new AWS account in AWS Organizations Create a transit gateway in thisaccount and use AWS Resource Access Manager to share the transit gateway with theorganization. In each of the microservice VPCs. create a transit gateway attachment to theshared transit gateway Update the route tables of each VPC to use the transit gatewayCreate a Network Load Balancer (NLB) in each of the microservice VPCs Use the NLBDNS names for communication between microservices.

Question # 3

A security team is concerned that a developer can unintentionally attach an Elastic IPaddress to an Amazon EC2 instance in production. No developer should be allowed toattach an Elastic IP address to an instance. The security team must be notified if anyproduction server has an Elastic IP address at any timeHow can this task be automated'?

B. Attach an 1AM policy to the developers' 1AM group to deny associate-addresspermissions Create a custom AWS Config rule to check whether an Elastic IP address isassociated with any instance tagged as production, and alert the security team
C. Ensure that all 1AM groups associated with developers do not have associate-address permissions. Create a scheduled AWS Lambda function to check whether an Elastic IPaddress is associated with any instance tagged as production, and alert the secunty team ifan instance has an Elastic IP address associated with it
D. Create an AWS Config rule to check that all production instances have EC2 1AM rolesthat include deny associate-address permissions Verify whether there is an Elastic IPaddress associated with any instance, and alert the security team if an instance has anElastic IP address associated with it.

Question # 5

A company has an AWS CodeDeploy application. The application has a deployment groupthat uses a single tag group to identify instances for the deployment of ApplicationA. Thesingle tag group configuration identifies instances that have Environment=Production andName=ApplicattonA tags for the deployment of ApplicationA.The company launches an additional Amazon EC2 instance with Department=MarketingEnvironment^Production. and Name=ApplicationB tags. On the next CodeDeploydeployment of ApplicationA. the additional instance has ApplicationA installed on it. ADevOps engineer needs to configure the existing deployment group to preventApplicationA from being installed on the additional instanceWhich solution will meet these requirements?

A. Change the current single tag group to include only the Environment=Production tagAdd another single tag group that includes only the Name=ApplicationA tag.
B. Change the current single tag group to include the Department=MarketmgEnvironment=Production and Name=ApplicationAtags
C. Add another single tag group that includes only the Department=Marketing tag. Keepthe Environment=Production and Name=ApplicationA tags with the current single tag group
