After a daily scrum with your development teams, you've agreed that using Blue/Green style deployments would benefit the team. Which technique should you use to deliver this new requirement?

An application has microservices spread across different AWS accounts and is integrated with an on-premises legacy system for some of its functionality. Because of the segmented architecture and missing logs, every time the application experiences issues, it is taking too long to gather the logs to identify the issues. A DevOps Engineer must fix the log aggregation process and provide a way to centrally analyze the logs. Which is the MOST efficient and cost-effective solution?

For AWS Auto Scaling, what is the first transition state an existing instance enters after leaving steady state in Standby mode?

A company hosts parts of a Python-based application using AWS Elastic Beanstalk. An Elastic Beanstalk CLI is being used to create and update the environments. The Operations team detected an increase in requests in one of the Elastic Beanstalk environments that caused downtime overnight. The team noted that the policy used for AWS Auto Scaling is NetworkOut. Based on load testing metrics, the team determined that the application needs to scale CPU utilization to improve the resilience of the environments. The team wants to implement this across all environments automatically. Following AWS recommendations, how should this automation be implemented?

If you want CloudFormation stack status updates to show up in a continuous delivery system in as close to real time as possible, how should you achieve this?

A company updated the AWS CloudFormation template for a critical business application. The stack update process failed due to an error in the updated template, and AWS CloudFormation automatically began the stack rollback process. Later, a DevOps engineer discovered that the application was still unavailable and that the stack was in the UPDATE_ROLLBACK_FAILED state. Which combination of actions should the DevOps engineer perform so that the stack rollback can complete successfully? (Choose two.)

Question 213

A company is building a solution for storing files containing Personally Identifiable Information (PII) on AWS. Requirements state:

All data must be encrypted at rest and in transit.

All data must be replicated in at least two locations that are at least 500 miles apart.

Which solution meets these requirements?

Create primary and secondary Amazon S3 buckets in two separate Availability Zones that are at least 500 miles apart. Use a bucket policy to enforce access to the buckets only through HTTPS. Use a bucket policy to enforce Amazon S3 SSECon all objects uploaded to the bucket. Configure cross-region replication between the two buckets.

Create primary and secondary Amazon S3 buckets in two separate AWS Regions that are at least 500 miles apart. Use a bucket policy to enforce access to the buckets only through HTTPS. Use a bucket policy to enforce S3-Managed Keys (SSES3) on all objects uploaded to the bucket. Configure cross-region replication between the two buckets.

Create primary and secondary Amazon S3 buckets in two separate AWS Regions that are at least 500 miles apart. Use an IAM role to enforce access to the buckets only through HTTPS. Use a bucket policy to enforce Amazon S3- Managed Keys (SSE-S3) on all objects uploaded to the bucket. Configure cross-region replication between the two buckets.

Question 214

A DevOps Engineer must track the health of a stateless RESTful service sitting behind a Classic ILoad Balancer. The deployment of new application revisions is through a CI/CD pipeline. If the service's latency increases beyond a defined threshold, deployment should be stopped until the service has recovered.

Which of the following methods allow for the QUICKEST detection time?

Use Amazon CloudWatch metrics provided by Elastic Load Balancing to calculate average latency. Alarm and stop deployment when latency increases beyond the defined threshold.

Use AWS Lambda and Elastic Load Balancing access logs to detect average latency. Alarm and stop deployment when latency increases beyond the defined threshold.

Use AWS CodeDeploy's MinimumHealthyHosts setting to define thresholds for rolling back deployments. If these thresholds are breached, roll back the deployment.

Use Metric Filters to parse application logs in Amazon CloudWatch Logs. Create a filter for latency. Alarm and stop deployment when latency increases beyond the defined threshold.

Question 215

A company has multiple environments that run applications on Amazon EC2 instances. The company wants to track costs and has defined a new rule that states that all production EC2 instances must be tagged with a CostCenter tag. A DevOps engineer has created a tag policy to validate the use of the CostCenter tag, has activated the option to prevent noncompliant tagging operations for this tag, and has attached the policy to the production OU in AWS Organizations. The DevOps engineer generates a compliance report for the entire organization and ensures that all the deployed instances have the correct tags configured. The DevOps engineer also verifies that the CostCenter tag cannot be removed from an EC2 instance that runs in one of the production accounts.

After some time, the DevOps engineer notices that several EC2 instances have been launched in the production accounts without the configuration of the CostCenter tag. What should the DevOps engineer do to ensure that all production EC2 instances are launched with the CostCenter tag configured?

Attach the tag policy to the organization root to ensure that the policy applies to all EC2 instances.

Create an SCP that requires the CostCenter tag during the launch of EC2 instances.

In the AWS Billing and Cost Management console of the management account, activate the CostCenter tag as a cost allocation tag.

Activate the AWS Config required-tags managed rule in all production accounts. Ensure that the rule evaluates the CostCenter tag.

Question 218

A company has a single Developer writing code for an automated deployment pipeline. The Developer is storing source code in an Amazon S3 bucket for each project. The company wants to add more Developers to the team but is concerned about code conflicts and lost work. The company also wants to build a test environment to deploy newer versions of code for testing and allow Developers to automatically deploy to both environments when code is changed in the repository.

What is the MOST efficient way to meet these requirements?

Create an AWS CodeCommit repository for each project, use the master branch for production code, and create a testing branch for code deployed to testing. Use feature branches to develop new features and pull requests to merge code to testing and master branches.

Create another S3 bucket for each project for testing code, and use an AWS Lambda function to promote code changes between testing and production buckets. Enable versioning on all buckets to prevent code conflicts.

Create an AWS CodeCommit repository for each project, and use the master branch for production and test code with different deployment pipelines for each environment. Use feature branches to develop new features.

Enable versioning and branching on each S3 bucket, use the master branch for production code, and create a testing branch for code deployed to testing. Have Developers use each branch for developing in each environment.
