In this scenario, the correct setup involves AWS Systems Manager for vulnerability detection on EC2 instances. Systems Manager helps in ensuring that instances meet compliance requirements and isn't limited solely to configuration management. It’s key in checking the state of your patches which is crucial for security. Moreover, integration with CloudTrail allows for capturing and analyzing login activities and other system-level operations, providing a comprehensive audit trail. This thorough approach addresses both requirements put forward by cyber security protocols in infrastructure management, combining the benefits of patch and configuration management with monitoring and logging.

For successful S3 cross-region replication when targeting a different AWS region and account, follow these steps: Firstly, create an IAM role in the source account specifically for replication (A). Next, set up a replication rule directly in the source bucket to manage where and how objects are replicated (E). Finally, it’s essential to modify the bucket policy of the target bucket to permit the replication IAM role from the source account to replicate objects into it (D). These steps ensure smooth replication across different accounts and regions while maintaining appropriate access controls.

To manage AWS EC2 instances centrally and ensure compliance with company policies, leveraging AWS Systems Manager is pivotal. Using AWS Config, as noted in option B, ensures that all instances are centrally managed under AWS Systems Manager, providing a unified platform for configurations. Option C effectively uses AWS Systems Manager to manage essential services like Amazon Inspector, Patch Manager, and CloudWatch, crucial for logging, security assessments, and patching. Moreover, option E utilizes AWS Systems Manager maintenance windows for scheduling these tasks effectively, standardizing operations across all instances. Combining these services secures, patches, and monitors EC2 instances consistently, aligning with standard operational procedures.

To optimize the performance of a CI/CD pipeline that builds, tests, and deploys multiple independent Lambda functions, consider adjusting the pipeline configuration to allow for parallel execution of these functions. Specifically, by setting actions for each Lambda function to have the same runOrder in the pipeline's stage, you establish concurrent processing which drastically cuts down the overall completion time. This method leverages AWS CodePipeline's ability to manage simultaneous actions effectively, improving throughput without the need for additional compute resources or environment alterations.

The optimal solution involves using Amazon DynamoDB to manage licenses dynamically as it allows for real-time tracking and updates, which is crucial for scalability up to 200 nodes. DynamoDB's ability to effectively handle these updates and queries ensures that the system can dynamically assign and reclaim licenses as instances scale up or down. This setup not only automates the process but also provides an efficient way to integrate a dashboard for real-time license tracking, catering directly to the company's requirements for automation and monitoring.
