A company has business operations in the United States and in Europe. The company's public applications are running on AWS and use three transit gateways. The transit gateways are located in the us-west-2, us-east-1, and eu-central-1 Regions. All the transit gateways are connected to each other in a full mesh configuration. The company accidentally removes the route to the eu-central-1 VPCs from the us-west-2 transit gateway route table. The company also accidentally removes the route to the us-west-2 VPCs from the eu-central-1 transit gateway route table. How can a network engineer identify the misconfiguration with the LEAST operational overhead?
