Amazon ANS-C01 Exam - Topic 5 Question 11 Discussion

A company has a global network and is using transit gateways to connect AWS Regions together. The company finds that two Amazon EC2 instances in different Regions are unable to communicate with each other. A network engineer needs to troubleshoot this connectivity issue.What should the network engineer do to meet this requirement?
B) Use AWS Network Manager Route Analyzer to analyze routes in the transit gateway route tables. Verify that the VPC route tables are correct. Use AWS Firewall Manager to analyze the IP traffic that security group rules and network ACL rules accept or reject in the VPC. and D) Use VPC Reachability Analyzer to analyze routes in the transit gateway route tables. Verify that the VPC route tables are correct. Use VPC flow logs to analyze the IP traffic that security group rules and network ACL rules accept or reject in the VPC.

I’m leaning towards option D because it mentions VPC Reachability Analyzer, which I think is specifically designed for this kind of issue, but I need to double-check how it compares to the other options.

Okay, let me think this through. The console is used to manage system settings, so that's likely one of the true statements. I'm not sure about the other options, though.

Hmm, Option D looks tempting, but why use VPC Reachability Analyzer when we have the tried and true VPC flow logs? Option C is the way to go, no doubt about it.
