The team asks a security engineer to help troubleshoot why some developers in the developer account (123456789012) in the developers group are not able to assume a cross-account role (ReadS3) into a production account (999999999999) to read the contents of an Amazon S3 bucket (productionapp). The two account policies are as follows: Which recommendations should the security engineer make to resolve this issue? (Select TWO.)
A security engineer recently rotated the host keys for an Amazon EC2 instance. The security engineer is trying to access the EC2 instance by using the EC2 Instance. Connect feature. However, the security engineer receives an error (or failed host key validation. Before the rotation of the host keys EC2 Instance Connect worked correctly with this EC2 instance. What should the security engineer do to resolve this error?

A company has an encrypted Amazon Aurora DB cluster in the us-east-1 Region. The DB cluster is encrypted with an AWS Key Management Service (AWS KMS) customer managed key. To meet compliance requirements, the company needs to copy a DB snapshot to the us-west-1 Region. However, when the company tries to copy the snapshot to us-west-1 the company cannot access the key that was used to encrypt the original database. What should the company do to set up the snapshot in us-west-1 with proper encryption?
A company's web application is hosted on Amazon EC2 instances running behind an Application Load Balancer (ALB) in an Auto Scaling group. An AWS WAF web ACL is associated with the ALB. AWS CloudTrail is enabled, and stores logs in Amazon S3 and Amazon CloudWatch Logs. The operations team has observed some EC2 instances reboot at random. After rebooting, all access logs on the instances have been deleted. During an investigation, the operations team found that each reboot happened just after a PHP error occurred on the new-user-creation.php file. The operations team needs to view log information to determine if the company is being attacked. Which set of actions will identify the suspect attacker's IP address for future occurrences?
A security engineer has noticed an unusually high amount of traffic coming from a single IP address. This was discovered by analyzing the Application Load Balancer's access logs. How can the security engineer limit the number of requests from a specific IP address without blocking the IP address?

A company receives a notification from the AWS Abuse team about an AWS account The notification indicates that a resource in the account is compromised The company determines that the compromised resource is an Amazon EC2 instance that hosts a web application The compromised EC2 instance is part of an EC2 Auto Scaling group The EC2 instance accesses Amazon S3 and Amazon DynamoDB resources by using an 1AM access key and secret key The 1AM access key and secret key are stored inside the AMI that is specified in the Auto Scaling group's launch configuration The company is concerned that the credentials that are stored in the AMI might also have been exposed The company must implement a solution that remediates the security concerns without causing downtime for the application The solution must comply with security best practices Which solution will meet these requirements'?

Suggested answer: C

Explanation:

The AWS documentation states that you can create a new AMI without the potentially compromised credentials and create an 1AM role that includes the correct permissions. You can then create a launch template for the Auto Scaling group to reference the new AMI and 1AM role. This method is the most secure way to remediate the security concerns without causing downtime for the application.
