Exam question from Amazon's AWS Certified Advanced Networking - Specialty ANS-C01
Question #: 117
Topic #: 1
[All AWS Certified Advanced Networking - Specialty ANS-C01 Questions]

Two companies are merging. The companies have a large AWS presence with multiple VPCs and are designing connectivity between their AWS networks. Both companies are using AWS Direct Connect with a Direct Connect gateway. Each company also has a transit gateway and multiple AWS Site-to-Site VPN connections from its transit gateway to on-premises resources. The new solution must optimize network visibility, throughput, logging, and monitoring.

Which solution will meet these requirements?

  • A. Configure a Site-to-Site VPN connection between each company's transit gateway to establish reachability between the respective networks. Configure VPC Flow Logs for all VPCs. Publish the flow logs to Amazon CloudWatch. Use VPC Reachability Analyzer to monitor connectivity.
  • B. Configure a Site-to-Site VPN connection between each company's transit gateway to establish reachability between the respective networks. Configure VPC Flow Logs for all VPCs. Publish the flow logs to Amazon CloudWatch. Use AWS Transit Gateway Network Manager to monitor the transit gateways and their respective connections.
  • C. Configure transit gateway peering between each company's transit gateway. Configure VPC Flow Logs for all VPCs. Publish the flow logs to Amazon CloudWatch. Use VPC Reachability Analyzer to monitor connectivity.
  • D. Configure transit gateway peering between each company's transit gateway. Configure VPC Flow Logs for all VPCs. Publish the flow logs to Amazon CloudWatch. Use AWS Transit Gateway Network Manager to monitor the transit gateways, their respective connections, and the transit gateway peering link.

transit gateway peering will allow the communication between all networks. To monitor the overall infrastructure, AWS Transit Gateway Network Manager is utilized for this purpose. https://aws.amazon.com/transit-gateway/network-manager/

VPC Reachability Analyzer is a network diagnostics tool that troubleshoots reachability between two endpoints in a VPC, or within multiple VPCs. this is not in the requirement. Moreover, site-to-site vpn only allows 1.25Gbps which seems not allowing throughput optimization between companies as in the requirement.
