Amazon DOP-C01 Practice Test - Questions Answers, Page 49

When an Auto Scaling group is running in Amazon Elastic Compute Cloud (EC2), your application rapidly scales up and down in response to load within a 10-minute window; however, after the load peaks, you begin to see problems in your configuration management system where previously terminated Amazon EC2 resources are still showing as active. What would be a reliable and efficient way to handle the cleanup of Amazon EC2 resources within your configuration management system? (Choose two.)

A company recently migrated its legacy application from on-premises to AWS. The application is hosted on Amazon EC2 instances behind an Application Load Balancer, which is behind Amazon API Gateway. The company wants to ensure users experience minimal disruptions during any deployment of a new version of the application. The company also wants to ensure it can quickly roll back updates if there is an issue. Which solution will meet these requirements with MINIMAL changes to the application?

An Application team is refactoring one of its internal tools to run in AWS instead of on-premises hardware. All of the code is currently written in Python and is standalone. There is also no external state store or relational database to be queried.

Which deployment pipeline incurs the LEAST amount of changes between development and production?

A company manages an application that stores logs in Amazon CloudWatch Logs. The company wants to archive the logs in Amazon S3. Logs are rarely accessed after 90 days and must be retained for 10 years. Which combination of steps should a DevOps engineer take to meet these requirements? (Choose two.)

A company discovers that some IAM users have been storing their AWS access keys in configuration files that have been pushed to a Git repository hosting service. Which solution will require the LEAST amount of management overhead while preventing the exposed AWS access keys from being used?

A DevOps engineer is deploying an AWS Service Catalog portfolio using AWS CodePipeline. The pipeline should create products and templates based on a manifest file in either JSON or YAML, and should enforce security requirements on all AWS Service Catalog products managed through the pipeline.

Which solution will meet the requirements in an automated fashion?

You run a large number of applications on Amazon EC2 instances. Each application has associated metadata, such as cost center, support contact, and application ID. Many applications usually co-exist on each Amazon EC2 instance, so the amount of metadata per instance can range from 10 to 200 items. The customer wants to be able to quickly access this metadata using an API without logging into the instances. Which of the following options will satisfy their requirements?

(Choose two.)

A DevOps Engineer is designing a deployment strategy for a web application. The application will use an Auto Scaling group to launch Amazon EC2 instances using an AMI. The same infrastructure will be deployed in multiple environments (development, test, and quality assurance). The deployment strategy should meet the following requirements:

• Minimize the startup time for the instance

• Allow the same AMI to work in multiple environments

• Store secrets for multiple environments securelyHow should this be accomplished?

You are doing a load testing exercise on your application hosted on AWS. While testing your Amazon RDS MySQL DB instance, you notice that when you hit 100% CPU utilization on it, your application becomes non- responsive. Your application is read-heavy.

What are methods to scale your data tier to meet the application's needs? (Choose three.)
