A company has several legacy systems which use both on-premises
servers as well as EC2 instances in AWS. The cluster nodes in AWS are
configured to have a local IP address and a fixed hostname in order for the
on-premises servers to communicate with them. There is a requirement to
automate the configuration of the cluster which consists of 10 nodes to
ensure high availability across three Availability Zones. There should also
be a corresponding elastic network interface in a specific subnet for each
Availability Zone. Each of the cluster node's local IP address and hostname

must be static and should not change even if the instance reboots or gets
terminated.
Which of the following solutions below provides the LEAST amount of effort
to automate this architecture?
Set up a CloudFormation child stack template which launches an Auto
Scaling group consisting of just one EC2 instance then provide a list of
ENIs, hostnames, and the specific AZs as stack parameters. Set both the
MinSize and MaxSize parameters of the Auto Scaling group to 1. Add a
user data script that will attach an ENI to the instance once launched. Use
CloudFormation nested stacks to provision a total of 10 nodes needed for
the cluster, and deploy the stack using a master template.

A company that develops smart home devices has a set of serverless APIs
that uses several independent AWS Lambda functions that handles web,
mobile, Internet of Things (IoT), and 3rd party API requests. The current
CI/CD pipeline builds, tests, packages, and deploys each Lambda function
in sequence using AWS CodePipeline and AWS CodeBuild. A CloudWatch
Events rule is used to monitor and ensure that the pipeline execution starts
promptly after a code change has been made. The SysOps team monitors
all of the AWS resources as well as the performance of each pipeline. They
noticed that for the past few days, the pipeline takes too long to finish the
build and deployment process. The team instructed a DevOps Engineer to
implement a solution that will expedite the deployment process of the
independent Lambda functions.
Which of the following is the MOST suitable solution that the DevOps
Engineer should implement?
Execute actions for each Lambda function in parallel by setting up a
configuration that specifies the same runOrder value in CodePipeline.
