Introduction
This comprehensive practice assessment is designed to evaluate and enhance the
technical proficiency required for the AWS Certified DevOps Engineer professional
level. The exam focuses on the implementation and management of continuous
delivery systems and methodologies on the AWS platform. Candidates will be
assessed on their ability to automate infrastructure, deploy code using CI/CD
pipelines, and maintain robust monitoring and logging solutions. The questions are
,structured as multiple-choice and complex scenario-based inquiries, mirroring the
rigor of the official certification. Emphasis is placed on real-world application, security
best practices, and strategic decision-making within high-scale cloud environments to
ensure operational excellence and reliability.
SECTION ONE: QUESTIONS 1–100
1. A company needs to automate the deployment of a serverless application using
AWS CodePipeline. The application consists of AWS Lambda functions and
Amazon API Gateway. Which service should be used to define the serverless
resources and handle the deployment via the pipeline?
A. AWS Elastic Beanstalk
B. AWS OpsWorks
C. AWS Serverless Application Model (SAM)
D. AWS CloudTrail
🟢 C. AWS Serverless Application Model (SAM)
🔴 RATIONALE: AWS SAM is specifically designed for defining serverless
applications. It integrates natively with AWS CodeDeploy and CodePipeline to
,automate the deployment of Lambda functions, API Gateway, and DynamoDB tables
using a simplified syntax built on CloudFormation.
2. A DevOps Engineer is implementing a blue/green deployment strategy for an
application running on Amazon EC2 instances behind an Application Load
Balancer (ALB). Which method provides the most control over shifting traffic in
small increments?
A. Swapping CNAME records in Amazon Route 53
B. Using AWS CodeDeploy with a linear deployment configuration
C. Modifying the Auto Scaling group launch template
D. Updating the ALB listener rules to point to a new target group manually
🟢 B. Using AWS CodeDeploy with a linear deployment configuration
🔴 RATIONALE: AWS CodeDeploy supports "Linear" and "Canary" deployment
configurations for traffic shifting. Linear configurations allow a specific percentage of
traffic to shift every fixed number of minutes, providing granular control and easy
rollback capabilities.
3. An organization requires that all Amazon S3 buckets created in their account
must have logging enabled. How can this policy be enforced automatically?
, A. Use an IAM policy that denies the s3:CreateBucket action
B. Create an AWS Config rule with a remediation action via AWS Systems Manager
C. Schedule a Lambda function to run every hour to check bucket settings
D. Enable S3 Block Public Access at the account level
🟢 B. Create an AWS Config rule with a remediation action via AWS Systems
Manager
🔴 RATIONALE: AWS Config can monitor resource configurations against desired
rules. By pairing a managed rule (s3-bucket-logging-enabled) with an AWS Systems
Manager Automation document, the system can automatically remediate non-
compliant buckets.
4. A development team uses a Git-based workflow. They want to ensure that every
time code is merged into the 'main' branch, a build is automatically triggered in
AWS CodeBuild. Which mechanism should be used?
A. AWS Trusted Advisor
B. CloudWatch Logs filter
C. Webhooks or repository triggers in AWS CodeCommit
D. Periodic polling via an EC2 cron job
