You have a code repository that uses Amazon S3 as a data store. During a recent audit of your security controls, some concerns were raised about maintaining the integrity of the data in the Amazon S3 bucket. Another concern was raised around securely deploying code from Amazon S3 to applications running on Amazon EC2 in a virtual private cloud.
What are some measures that you can implement to mitigate these concerns? Choose 2 answers.

• A.Create an Amazon Identity and Access Management role with authorization to access the Amazon 53 bucket, and launch all of your application's Amazon EC2 instances with this role.
• B.Add an Amazon S3 bucket policy with a condition statement to allow access only from Amazon EC2 instances with RFC 1918 IP addresses and enable bucket versioning.
• C.Add an Amazon S3 bucket policy with a condition statement that requires multi-factor authentication in order to delete objects and enable bucket versioning.
• D.Use AWS Data Pipeline to lifecycle the data in your Amazon S3 bucket to Amazon Glacier on a weekly basis.
• E.Use AWS Data Pipeline with multi-factor authentication to securely deploy code from the Amazon .5.3 bucket to your Amazon EC2 instances.
• F.Use a configuration management service to deploy AWS Identity and Access Management user credentials to the Amazon EC2 instances.
  Use these credentials to securely access the Amazon S3 bucket when deploying code.

A media customer has several thousand amazon EC2 instances in an AWS account. The customer is using a Slack channel for team communications and important updates. A DevOps Engineer was told to send all AWS-scheduled maintenance notifications to the company Slack channel.
Which method should the Engineer use to implement this process in the LEAST amount of steps?

• A.Integrate AWS Trusted Advisor with AWS Config. Based on the AWS Config rules created, the AWS Config event can invoke an AWS Lambda function to send notifications to the Slack channel.
• B.Integrate EC2 events with Amazon CloudWatch monitoring. Based on the CloudWatch Alarm created, the alarm can invoke an AWS Lambda function to send EC2 maintenance notifications to the Slack channel.
• C.Integrate AWS Support with AWS CloudTrail. Based on the CloudTrail lookup event created, the event can invoke an AWS Lambda function to pass EC2 maintenance notifications to the Slack channel.
• D.Integrate AWS Personal Health Dashboard with Amazon CloudWatch Events. Based on the CloudWatch Events created, the event can invoke an AWS Lambda function to send notifications to the Slack channel.
