A company uses AWS CodePipeline and AWS CodeDeploy to deploy application code to Amazon EC2 instances. The EC2 instances send application logs and CodeDeploy logs to Amazon CloudWatch.

Recently, the company manually rolled back a deployment because of application errors. The company wants to automate the rollback process when application errors occur.

Which solution will meet these requirements?

Options:

A.

Create a CloudWatch metric based on the application logs. Create a CloudWatch alarm based on the metric that will activate when application errors occur. Change the deployment group settings to use the CloudWatch alarm configuration. Configure the deployment group to use an auto rollback configuration.

B.

Configure a CloudWatch alarm that uses a custom metric for application errors that are recorded in the CodeDeploy agent logs. Configure the current deployment to use the CloudWatch alarm for its alarm configuration. Configure the deployment to use an auto rollback configuration.

C.

Create an AWS Lambda function that will create a new deployment by using the last successful application deployment. Create an Amazon EventBridge rule that matches events from CodeDeploy that have a deployment status of FAILURE. Configure the EventBridge rule to target the Lambda function.

D.

Create an AWS Lambda function that will create a new deployment group for the application deployment. Create a CloudWatch alarm based on metrics from the application logs. Configure the alarm to activate when an application error occurs on an EC2 instance. Configure the CloudWatch alarm to invoke the Lambda function.

Question 2

A DevOps engineer is working on a member account in an organization in AWS Organizations with all features enabled. The account has sensitive data stored in Amazon S3 buckets.

The DevOps engineer must ensure that all public access to S3 buckets in the account is blocked. If the account-level public access settings change in the future, the changes must be reverted automatically so that all public access is blocked again.

Which solution meets these requirements?

Options:

A.

Enable AWS Security Hub in the account. Enable the Security Hub control to evaluate the account-level block public access settings. Enable automated remediation for the Security Hub control.

B.

Set up AWS Config in the account. Create an AWS Config managed rule that evaluates the S3 block public access settings. Enable automated remediation for the rule by using a predefined AWS Systems Manager runbook to configure S3 block public access settings.

C.

In the organization ' s management account, create an SCP that denies S3 actions from outside the AWS account. Attach the SCP to the member account.

D.

Enable Amazon Macie in the account. Create an Amazon EventBridge rule with an event pattern that matches Macie policy findings. Configure the rule with an EventBridge target to run a predefined AWS Systems Manager runbook to configure S3 block public access settings.

Question 3

A company runs a workload on Amazon EC2 instances. The company needs a control that requires the use of Instance Metadata Service Version 2 (IMDSv2) on all EC2 instances in the AWS account. If an EC2 instance does not prevent the use of Instance Metadata Service Version 1 (IMDSv1), the EC2 instance must be terminated.

Which solution will meet these requirements?

Options:

A.

Set up AWS Config in the account. Use a managed rule to check EC2 instances. Configure the rule to remediate the findings by using AWS Systems Manager Automation to terminate the instance.

B.

Create a permissions boundary that prevents the ec2:Runlnstance action if the ec2:MetadataHttpTokens condition key is not set to a value of required. Attach the permissions boundary to the IAM role that was used to launch the instance.

C.

Set up Amazon Inspector in the account. Configure Amazon Inspector to activate deep inspection for EC2 instances. Create an Amazon EventBridge rule for an Inspector2 finding. Set an AWS Lambda function as the target to terminate the instance.

D.

Create an Amazon EventBridge rule for the EC2 instance launch successful event. Send the event to an AWS Lambda function to inspect the EC2 metadata and to terminate the instance.
