A company has implemented IAM WAF and Amazon CloudFront for an application. Theapplication runs on Amazon EC2 instances that are part of an Auto Scaling group. TheAuto Scaling group is behind an Application Load Balancer (ALB).The IAM WAF web ACL uses an IAM Managed Rules rule group and is associated with theCloudFront distribution. CloudFront receives the request from IAM WAF and then uses theALB as the distribution's origin.During a security review, a security engineer discovers that the infrastructure is susceptibleto a large, layer 7 DDoS attack.How can the security engineer improve the security at the edge of the solution to defendagainst this type of attack?
A. Configure the CloudFront distribution to use the Lambda@Edge feature. Create an IAMLambda function that imposes a rate limit on CloudFront viewer requests. Block the requestif the rate limit is exceeded.
B. Configure the IAM WAF web ACL so that the web ACL has more capacity units toprocess all IAM WAF rules faster.
C. Configure IAM WAF with a rate-based rule that imposes a rate limit that automaticallyblocks requests when the rate limit is exceeded.
D. Configure the CloudFront distribution to use IAM WAF as its origin instead of the ALB.

A. Create an Amazon CloudFront distribution and configure the ALB as the origin
B. Block the malicious IPs with a network access list (NACL).
C. Create an IAM Web Application Firewall (WAF). and attach it to the ALB

A company recently had a security audit in which the auditors identified multiple potentialthreats. These potential threats can cause usage pattern changes such as DNS access peak, abnormal instance traffic, abnormal network interface traffic, and unusual Amazon S3API calls. The threats can come from different sources and can occur at any time. Thecompany needs to implement a solution to continuously monitor its system and identify allthese incoming threats in near-real time.Which solution will meet these requirements?

A. Filter IAM CloudTrail logs for KeyRotaton events
B. Monitor Amazon CloudWatcn Events for any IAM KMS CMK rotation events
C. Using the IAM CLI. run the IAM kms gel-key-relation-status operation with the --key-idparameter to check the CMK rotation date

A security engineer needs to build a solution to turn IAM CloudTrail back on in multiple IAMRegions in case it is ever turned off.What is the MOST efficient way to implement this solution?
A. Use IAM Config with a managed rule to trigger the IAM-EnableCloudTrail remediation.
B. Create an Amazon EventBridge (Amazon CloudWatch Events) event with acloudtrail.amazonIAM.com event source and a StartLogging event name to trigger an IAMLambda function to call the StartLogging API.

D. Monitor IAM Trusted Advisor to ensure CloudTrail logging is enabled.
An application is running on an Amazon EC2 instance that has an IAM role attached. TheIAM role provides access to an AWS Key Management Service (AWS KMS) customermanaged key and an Amazon S3 bucket. The key is used to access 2 TB of sensitive datathat is stored in the S3 bucket.A security engineer discovers a potential vulnerability on the EC2 instance that could resultin the compromise of the sensitive data. Due to other critical operations, the securityengineer cannot immediately shut down the EC2 instance for vulnerability patching.What is the FASTEST way to prevent the sensitive data from being exposed?
A. Download the data from the existing S3 bucket to a new EC2 instance. Then delete thedata from the S3 bucket. Re-encrypt the data with a client-based key. Upload the data to anew S3 bucket.
B. Block access to the public range of S3 endpoint IP addresses by using a host-basedfirewall. Ensure that internet-bound traffic from the affected EC2 instance is routed throughthe host-based firewall.
C. Revoke the IAM role's active session permissions. Update the S3 bucket policy to denyaccess to the IAM role. Remove the IAM role from the EC2 instance profile.
D. Disable the current key. Create a new KMS key that the IAM role does not have accessto, and re-encrypt all the data with the new key. Schedule the compromised key fordeletion.

A company has an organization in AWS Organizations. The company wants to use AWSCloudFormation StackSets in the organization to deploy various AWS design patterns intoenvironments. These patterns consist of Amazon EC2 instances, Elastic Load Balancing(ELB) load balancers, Amazon RDS databases, and Amazon Elastic Kubernetes Service(Amazon EKS) clusters or Amazon Elastic Container Service (Amazon ECS) clusters.Currently, the company's developers can create their own CloudFormation stacks toincrease the overall speed of delivery. A centralized CI/CD pipeline in a shared servicesAWS account deploys each CloudFormation stack.The company's security team has already provided requirements for each service inaccordance with internal standards. If there are any resources that do not comply with theinternal standards, the security team must receive notification to take appropriate action.The security team must implement a notification solution that gives developers the ability tomaintain the same overall delivery speed that they currently have.Which solution will meet these requirements in the MOST operationally efficient way?
A. Create an Amazon Simple Notification Service (Amazon SNS) topic. Subscribe thesecurity team's email addresses to the SNS topic.

Configure theCI/CD pipeline to publish a notification to the SNS topic if any issues are found.
B. Create an Amazon Simple Notification Service (Amazon SNS) topic. Subscribe thesecurity team's email addresses to the SNS topic. Create custom rules in CloudFormationGuard for each resource configuration.

C. Create an Amazon Simple Notification Service (Amazon SNS) topic and an Am-azonSimple Queue Service (Amazon SQS) queue. Subscribe the security team's emailaddresses to the SNS topic. Create an Amazon S3 bucket in the shared services AWSaccount. Include an event notification to publish to the SQS queue when new objects areadded to the S3 bucket. Require the de-velopers to put their CloudFormation templates inthe S3 bucket. Launch EC2 instances that automatically scale based on the SQS queuedepth. Con-figure the EC2 instances to use CloudFormation Guard to scan the templatesand deploy the templates if there are no issues. Configure the CllCD pipe-line to publish anotification to the SNS topic if any issues are found.
D. Create a centralized CloudFormation stack set that includes a standard set of resourcesthat the developers can deploy in each AWS account. Configure each CloudFormationtemplate to meet the security requirements. For any new resources or configurations,update the CloudFormation template and send the template to the security team for review.When the review is com-pleted, add the new CloudFormation stack to the repository for thedevel-opers to use.
