Question 1

A popular e-commerce website which has customers across the globe is hosted in the us-east-1 AWS region with a backup site in the us-west-1 region. Due to an unexpected regional outage in the us-east-1 region, the company initiated their disaster recovery plan and turned on the backup site. However, they discovered that the actual failover still entails several hours of manual effort to prepare and switch over the database. They also noticed that the database is missing up to three hours of data transactions when the regional outage happened. Which of the following solutions should the DevOps engineer implement which will improve the RTO and RPO of the website for the cross-region failover?

A : eate a snapshot every hour using Amazon RDS scheduled instance lifecycle events which will also allow you to monitor specific RDS events. Perform a cross-region snapshot copy into the us-west-1 backup region once the SnapshotCreateComplete event occurred. Create an Amazon CloudWatch Alert which will trigger an action to restore the Amazon RDS database snapshot in the backup region when the CPU Utilization metric of the RDS instance in CloudWatch falls to 0% for more than 15 minutes.

B : Step Functions with 2 Lambda functions that call the RDS API to create a snapshot of the database, create a cross-region snapshot copy, and restore the database instance from a snapshot in the backup region. Use CloudWatch Events to trigger the function to take a database snapshot every hour. Set up an SNS topic that will receive published messages from AWS Health API, RDS availability and other events that will trigger the Lambda function to create a cross-region snapshot copy. During failover, Configure the Lambda function to restore the database from a snapshot in the backup region.

C : Use an ECS cluster to host a custom python script that calls the RDS API to create a snapshot of the database, create a cross-region snapshot copy, and restore the database instance from a snapshot in the backup region. Create a scheduled job using CloudWatch Events that triggers the Lambda function to snapshot a database instance every hour. Set up an SNS topic that will receive published messages about AWS-initiated RDS events from Trusted Advisor that will trigger the function to create a cross-region snapshot copy. During failover, restore the database from a snapshot in the backup region.

D : nfigure an Amazon RDS Multi-AZ Deployment configuration and place the standby instance in the us-west-1 region. Set up the RDS option group to enable multi-region availability for native automation of cross-region recovery as well as for continuous data replication. Set up a notification system using Amazon SNS which is integrated with AWS Health API to monitor RDS-related systems events and notify the Operations team. In the actual failover where the primary database instance is down, RDS will automatically make the standby instance in the backup region as the primary instance.

Answer: B

Question 2

A company hosts its staging website using an Amazon EC2 instance backed with Amazon EBS storage. The company wants to recover quickly with minimal data losses in the event of network connectivity issues or power failures on the EC2 instance.

Which solution will meet these requirements?

A : the instance to an EC2 Auto Scaling group with the minimum, maximum, and desired capacity set to 1.

B : the instance to an EC2 Auto Scaling group with a lifecycle hook to detach the EBS volume when the EC2 instance shuts down or terminates.

C : eate an Amazon CloudWatch alarm for the StatusCheckFailed System metric and select the EC2 action to recover the instance.

D : eate an Amazon CloudWatch alarm for the StatusCheckFailed Instance metric and select the EC2 action to reboot the instance

Answer: C

Question 3

You have developed an app that lets users quickly upload and share image snippets across various platforms such as mobile app, desktop web browser, and third party instant messaging apps. Your app relies on a Lambda function that detects each request’s User-Agent and automatically sends a corresponding image resolution based on the device. You want to have a consistent and fast experience for all your users around the world.

Which of the following options will you implement?

A : load your function on S3 and set it as CloudFront origin to run it.

B : ploy your function on Amazon API Gateway and set up an Edge-optimized API endpoint.

C : eate your function on Lambda and deploy it with Lambda@Edge.

D : eate your function on AWS Lambda and set it as a CloudFront origin.

Answer: C

Question 4

A company uses Amazon S3 to store proprietary information. The development team creates buckets for new projects on a daily basis. The security team wants to ensure that all existing and future buckets have encryption, logging, and versioning enabled. Additionally, no buckets should ever be publicly read or write accessible.

What should a DevOps engineer do to meet these requirements?

A : able AWS CloudTrail and configure automatic remediation using AWS Lambda.

B : able AWS Config rules and configure automatic remediation using AWS Systems Manager documents.

C : able AWS Trusted Advisor and configure automatic remediation using Amazon EventBridge.

D : able AWS Systems Manager and configure automatic remediation using Systems Manager documents.

Answer: B

Question 5

A software team is using AWS CodePipeline to automate its Java application release pipeline. The pipeline consists of a source stage, then a build stage, and then a deploy stage. Each stage contains a single action that has a runOrder value of 1.

The team wants to integrate unit tests into the existing release pipeline. The team needs a solution that deploys only the code changes that pass all unit tests.

Which solution will meet these requirements?

A : Modify the build stage. Add a test action that has a runOrder value of 1. Use AWS CodeDeploy as the action provider to run unit tests.

B : Modify the build stage. Add a test action that has a runOrder value of 2. Use AWS CodeBuild as the action provider to run unit tests.

C : Modify the deploy stage. Add a test action that has a runOrder value of 1. Use AWS CodeDeploy as the action provider to run unit tests.

D : Modify the deploy stage. Add a test action that has a runOrder value of 2. Use AWS CodeBuild as the action provider to run unit tests.
