NEW QUESTION # 129
A company is building a dataset catalog that runs on AWS Lambda functions. The company uses AWS CodeBuild to deliver product updates to the Lambda functions as container images by using AWS Serverless Application Model (AWS SAM).
The company uses a multi-account environment. The company has a test AWS account, a production account, and a central shared services account. A company policy requires all software build processes to occur within the shared services account. The company requires a solution that provides artifact storage and CI/CD tooling.
The company creates a pipeline in AWS CodePipeline in the shared services account.
Which combination of solutions will meet these requirements? (Select THREE.)
Answer: C,D,E
Explanation:
The build must run in the shared services account, while deployments must reach separate test and production accounts. Cross-account CodePipeline actions require roles in the target accounts and access to the pipeline artifact bucket. Therefore, the design needs a CodePipeline execution role in shared services, target-account cross-account roles, and a CodeBuild service role. CodePipeline artifacts belong in Amazon S3, while Lambda container images belong in Amazon ECR; CodeArtifact is for software packages, not pipeline artifacts or container image storage. The pipeline stages also need to reflect the actual delivery model: source, build container image, deploy to test, then deploy to production. AWS guidance shows CodeBuild creating Docker images and publishing them to ECR, which Lambda then uses as the container image source.
NEW QUESTION # 130
A company has a search application that has a web interface. The company uses Amazon CloudFront, Application Load Balancers (ALBs), and Amazon EC2 instances in an Auto Scaling group with a desired capacity of 3. The company uses prebaked AMIs. The application starts in 1 minute. The application queries an Amazon OpenSearch Service cluster. The application is deployed to multiple Availability Zones. Because of compliance requirements, the application needs to have a disaster recovery (DR) environment in a separate AWS Region. The company wants to minimize the ongoing cost of the DR environment and requires an RTO and an RPO of under 30 minutes. The company has created an ALB in the DR Region. Which solution will meet these requirements?
Answer: C
NEW QUESTION # 131
A company has a fleet of Amazon EC2 instances that run Linux in a single AWS account. The company is using an AWS Systems Manager Automation task across the EC2 instances.
During the most recent patch cycle, several EC2 instances went into an error state because of insufficient available disk space. A DevOps engineer needs to ensure that the EC2 instances have sufficient available disk space during the patching process in the future.
Which combination of steps will meet these requirements? {Select TWO.)
Answer: A,D
Explanation:
Ensure that the Amazon CloudWatch agent is installed on all EC2 instances:
* The Amazon CloudWatch agent collects and logs metrics and sends them to Amazon CloudWatch.
* To install the CloudWatch agent:
* Download the CloudWatch agent package.
* Install the agent on your EC2 instances.
* Configure the agent to collect disk space metrics.
Create an Amazon CloudWatch alarm to monitor available disk space on all EC2 instances Add the alarm as a safety control to the Systems Manager Automation task:
* Create CloudWatch alarms to monitor the available disk space and trigger notifications or actions when the disk space falls below a defined threshold.
* Add the CloudWatch alarm to the Systems Manager Automation task to halt or fail the task if disk space is insufficient.
* To create the alarm:
* Navigate to the CloudWatch console and create a new alarm.
* Set the metric to monitor (e.g., disk space utilization).
* Define the threshold and notification actions.
References:
* Amazon CloudWatch agent
* Creating Amazon CloudWatch alarms
NEW QUESTION # 132
A software engineering team is using AWS CodeDeploy to deploy a new version of an application. The team wants to ensure that if any issues arise during the deployment, the process can automatically roll back to the previous version.
During the deployment process, a health check confirms the application's stability. If the health check fails, the deployment must revert automatically.
Which solution will meet these requirements?
Answer: B
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
AWS CodeDeploy supportsautomatic rollbackcapabilities, which allow the deployment to automatically revert to the last known good revision if a failure occurs during the deployment or if health checks fail.
* You can enable automatic rollback on CodeDeploy deployments by configuring rollback settings in the deployment group.
* Automatic rollback triggers can include failed deployments and alarms failing during the deployment lifecycle, which means if the health check fails, CodeDeploy will automatically roll back without manual intervention.
* Lifecycle event hooks (Option A) provide custom scripting capabilities during deployment but do not provide built-in rollback automation.
* CloudFormation (Option B) can deploy and manage infrastructure but does not control CodeDeploy rollback.
* CloudWatch alarms (Option C) can trigger notifications but require manual or additional automation to trigger rollback.Hence, enablingCodeDeploy's automatic rollback settingsis the simplest and most reliable method for automatic rollback upon health check failure.
Reference from AWS Official Documentation and Study Guide:
* AWS CodeDeploy Automatic Rollback:"You can configure automatic rollback in AWS CodeDeploy to roll back a deployment if it fails or if specified CloudWatch alarms are triggered."(AWS CodeDeploy User Guide - Automatic Rollbacks)
* AWS Certified DevOps Engineer Professional Study Guide:"Leverage CodeDeploy automatic rollback features to reduce downtime and ensure application stability during deployments."
NEW QUESTION # 133
A company has chosen AWS to host a new application. The company needs to implement a multi-account strategy. A DevOps engineer creates a new AWS account and an organization in AWS Organizations. The DevOps engineer also creates the OU structure for the organization and sets up a landing zone by using AWS Control Tower.
The DevOps engineer must implement a solution that automatically deploys resources for new accounts that users create through AWS Control Tower Account Factory. When a user creates a new account, the solution must apply AWS CloudFormation templates and SCPs that are customized for the OU or the account to automatically deploy all the resources that are attached to the account. All the OUs are enrolled in AWS Control Tower.
Which solution will meet these requirements in the MOST automated way?
Answer: B
