NEW QUESTION # 185
A company has an organization in AWS Organizations with many OUs that contain many AWS accounts.
The organization has a dedicated delegated administrator AWS account.
The company needs the accounts in one OU to have server-side encryption enforced for all Amazon Elastic Block Store (Amazon EBS) volumes and Amazon Simple Queue Service (Amazon SQS) queues that are created or updated on an AWS CloudFormation stack.
Which solution will enforce this policy before a CloudFormation stack operation in the accounts of this OU?
Answer: A
Explanation:
The requirement specifies enforcing encryption before CloudFormation creates or updates resources. This is key because preventive enforcement must occur during the provisioning workflow, not after resources already exist. AWS provides CloudFormation Hooks specifically for this purpose. A Hook allows an organization to intercept a CloudFormation stack operation and validate resource configurations before provisioning occurs.
This feature is recommended by AWS for pre-deployment governance such as enforcing encryption policies, tag compliance, or security restrictions.
By enabling trusted access between CloudFormation StackSets and AWS Organizations, the Hook can be deployed centrally from the delegated administrator account across all accounts in the specified OU. Any attempt to create or update EBS volumes or SQS queues through CloudFormation is validated first by the Hook. If encryption is not configured, the operation fails immediately.
Option C (SCP) blocks API calls globally, but SCPs cannot perform conditional logic based on resource properties passed by CloudFormation prior to creation. Option B (AWS Config) detects violations after resources already exist, which does not satisfy "before stack operation." Option D (Lambda remediation) also occurs after the resource is created.
Thus, CloudFormation Hooks distributed via StackSets provide the only solution that enforces compliance before the provisioning lifecycle
NEW QUESTION # 186
A DevOps engineer is implementing governance controls for a company that requires its infrastructure to be housed within the United States. The company has many AWS accounts in an organization in AWS Organizations that has all features enabled. The engineer must restrict which AWS Regions the company can use. The engineer must also ensure that an alert is sent as soon as possible if any activity outside the governance policy occurs. The controls must be automatically enabled on any new Region outside the United States. Which combination of steps will meet these requirements? (Select TWO.)
Answer: D,E
NEW QUESTION # 187
A company's DevOps engineer uses AWS Systems Manager to perform maintenance tasks during maintenance windows. The company has a few Amazon EC2 instances that require a restart after notifications from AWS Health. The DevOps engineer needs to implement an automated solution to remediate these notifications. The DevOps engineer creates an Amazon EventBridge rule.
How should the DevOps engineer configure the EventBridge rule to meet these requirements?
Answer: B
Explanation:
AWS Health provides real-time events and information related to your AWS infrastructure. It can be integrated with Amazon EventBridge to act upon the health events automatically. If the maintenance notification from AWS Health indicates that an EC2 instance requires a restart, you can set up an EventBridge rule to respond to such events. In this case, the target of this rule would be a Lambda function that would trigger a Systems Manager automation to restart the EC2 instance during a maintenance window. Remember, AWS Health is the source of the events (not EC2 or Systems Manager), and AWS Lambda can be used to execute complex remediation tasks, such as scheduling maintenance tasks via Systems Manager.
The following are the steps involved in configuring the EventBridge rule to meet these requirements:
* Configure an event source of AWS Health, a service of EC2, and an event type that indicates instance maintenance.
* Target a newly created AWS Lambda function that registers an automation task to restart the EC2 instance during a maintenance window.
The AWS Lambda function will be triggered by the event from AWS Health. The function will then register an automation task to restart the EC2 instance during the next maintenance window.
NEW QUESTION # 188
A company containerized its Java app and uses CodePipeline. They want to scan images in ECR for vulnerabilities and reject images with critical vulnerabilities in a manual approval stage.
Which solution meets these?
Answer: C
Explanation:
* Amazon ECR enhanced scanninguses Amazon Inspector for vulnerability detection.
* EventBridge can capture Inspector scan findings.
* Lambda can process scan findings and reject manual approval if critical vulnerabilities exist.
* Options A and C use incorrect or less integrated services (basic scanning or Detective).
* Option B adds unnecessary complexity with SBOM and Athena.

NEW QUESTION # 189
A DevOps engineer manages an AWS CodePipeline pipeline that builds and deploys a web application on AWS. The pipeline has a source stage, a build stage, and a deploy stage. When deployed properly, the web application responds with a 200 OK HTTP response code when the URL of the home page is requested.
The home page recently returned a 503 HTTP response code after CodePipeline deployed the application. The DevOps engineer needs to add an automated test into the pipeline. The automated test must ensure that the application returns a 200 OK HTTP response code after the application is deployed. The pipeline must fail if the response code is not present during the test.
The DevOps engineer has added a CheckURL stage after the deploy stage in the pipeline.
What should the DevOps engineer do next to implement the automated test?
Answer: D
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
To add an automated test in AWS CodePipeline that checks the HTTP response code of a deployed application, the most straightforward and operationally efficient method is to create an AWS Lambda function that makes an HTTP request to the application URL, checks the response code, and then reports success or failure back to CodePipeline.
The Lambda function can be invoked as an action in the pipeline stage.
If the response code is not 200 OK, the Lambda function can return a failure, causing the pipeline stage to fail and halt further execution.
Option A's CloudWatch synthetic canary monitors are useful for ongoing monitoring but are not natively integrated as CodePipeline actions to control pipeline flow.
Option C incorrectly uses CodeDeploy action for testing, which is not designed for this purpose.
Option D introduces unnecessary complexity by deploying API Gateway and Device Farm, which is not required for a simple HTTP status check.
Therefore, option B provides a clean, simple, and fully automated way to enforce HTTP response validation within the pipeline.

"You can create Lambda invoke actions in your pipeline stages to run custom validation or testing functions." (AWS CodePipeline User Guide - Lambda Actions) AWS Lambda Function for Health Checks:
"Lambda functions can be used to perform health checks or API response validations and report results back to invoking services." (AWS Lambda Developer Guide)
