A company’s security team discovers that IAM access keys were potentially exposed. The DevOps team wants to implement a solution that will automatically disable any keys that are suspected of being compromised. The solution also must provide a notification to the security team.

Which solution will accomplish this?

Create an Amazon EventBridge (Amazon CloudWatch Events) event for Amazon Macie. Create an Amazon Simple Notification Service (Amazon SNS) topic with two subscriptions: one to notify the security team and another to invoke an AWS Lambda function that disables the access keys.

Which answer is the proper syntax for specifying two target hosts on the command line when running an Ansible Playbook?

ansible-playbook -h host1.example.com -i all playbook.yml
ansible-playbook -h host1.example.com -i all playbook.yml

ansible-playbook -i host1.example.com,host2.example.com playbook.yml
ansible-playbook -i host1.example.com,host2.example.com playbook.yml
Suggested answer: D

Explanation:

Ansible uses the `-i' flag for accepting an inventory file or host. To allow Ansible to determine if you are passing a host list versus an inventory file the list must be comma separated. If a single host is specified, a trailing comma must be present.

A company has a mission-critical application on AWS that uses automatic scaling. The company wants the deployment lifecycle to meet the following parameters:

• The application must be deployed one instance at a time to ensure the remaining fleet continues 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 deployment instance exceeds 85%. Which solution will meet these requirements?

Use AWS CloudFormation to create an AWS Step Functions state machine and Auto Scaling lifecycle hooks to move to one instance at a time into a wait state. Use AWS Systems Manager automation to deploy the update to each instance and move it back into the Auto Scaling group using the heartbeat timeout.

A retail company wants to use AWS Elastic Beanstalk to host its online sales website running on Java. Since this will be the production website, the CTO has the following requirements for the deployment strategy: Zero downtime. While the deployment is ongoing, the current Amazon EC2 instances in service should remain in service. No deployment or any other action should be performed on the EC2 instances because they serve production traffic. A new fleet of instances should be provisioned for deploying the new application version. Once the new application version is deployed successfully in the new fleet of instances, the new instances should be placed in service and the old ones should be removed. The rollback should be as easy as possible. If the new fleet of instances fail to deploy the new application version, they should be terminated and the current instances should continue serving traffic as normal. The resources within the environment (EC2 Auto Scaling group, Elastic Load Balancing, Elastic Beanstalk DNS CNAME) should remain the same and no DNS change should be made. Which deployment strategy will meet the requirements?
