A company has a single AWS account. The company runs workloads on Amazon EC2 instances in multiple VPCs in one AWS Region. The company also runs workloads in an on-premises data center that connects to the company's AWS account by using AWS Direct Connect.
The company needs all EC2 instances in the VPCs to resolve DNS queries tor the internal.company.com domain to the authoritative DNS server that is located in the on-premises data center. The solution must use private communication between the VPCs and the on-premises network. All route tables, network ACLs. and security groups are configured correctly between AWS and the on-premises data center.
Which combination of actions will meet these requirements? (Select THREE.)
Answer : C, E

Answer : A
A startup company recently migrated a large ecommerce website to AWS The website has experienced a 70% increase in sates Software engineers are using a private GitHub repository to manage code The DevOps team is using Jenkins for builds and unit testing The engineers need to receive notifications for bad builds and zero downtime during deployments The engineers also need to ensure any changes to production are seamless for users and can be rolled back in the event of a major issue
The software engineers have decided to use AWS CodePipeline to manage their build and deployment process
Which solution will meet these requirements'?
Answer : B
GitHub Webhooks to Trigger CodePipeline:
Configure GitHub webhooks to trigger the AWS CodePipeline pipeline. This ensures that every code push to the repository automatically triggers the pipeline, initiating the build and deployment process.
Unit Testing with Jenkins and AWS CodeBuild:
Use Jenkins integrated with the AWS CodeBuild plugin to perform unit testing. Jenkins will manage the build process, and the results will be handled by CodeBuild.
Notifications for Bad Builds:
Configure Amazon SNS (Simple Notification Service) to send alerts for any failed builds. This keeps the engineering team informed of build issues immediately, allowing for quick resolutions.
Blue/Green Deployment with AWS CodeDeploy:
Utilize AWS CodeDeploy with a blue/green deployment strategy. This method reduces downtime and risk by running two identical production environments (blue and green). CodeDeploy shifts traffic between these environments, allowing you to test in the new environment (green) while the old environment (blue) remains live. If issues arise, you can quickly roll back to the previous environment.
This solution provides seamless, zero-downtime deployments, and the ability to quickly roll back changes if necessary, fulfilling the requirements of the startup company.

A company wants to migrate virtual Microsoft workloads from an on-premises data center to AWS The company has successfully tested a few sample workloads on AWS. The company also has created an AWS Site-to-Site VPN connection to a VPC A solutions architect needs to generate a total cost of ownership (TCO) report for the migration of all the workloads from the data center
Simple Network Management Protocol (SNMP) has been enabled on each VM in the data center The company cannot add more VMs m the data center and cannot install additional software on the VMs The discovery data must be automatically imported into AWS Migration Hub
Which solution will meet these requirements?
Answer : A
AWS Application Migration Service:
AWS Application Migration Service (MGN) facilitates the migration of virtual machines (VMs) to AWS without installing additional software on the VMs. This agentless service helps in seamlessly migrating workloads to AWS.
AWS Migration Hub Strategy Recommendations:
AWS Migration Hub Strategy Recommendations offer insights and guidance for planning and implementing migration strategies. It helps in generating a Total Cost of Ownership (TCO) report by automatically importing discovery data from the VMs.
Generating the TCO Report:
The combined use of AWS Application Migration Service and Migration Hub Strategy Recommendations enables the automatic import of discovery data and the generation of an accurate TCO report, ensuring a smooth and cost-effective migration process.
