You are a junior network engineer with a medium$-$sized construction firm. They have multiple subnets to segregate traffic and only allow access between specific subnets. All subnets should be able to access the internet.

You are troubleshooting communications issues in your company's network. Devices on the network can communicate within their subnets, but they encounter obstacles when trying to communicate with other subnets and the internet.

To help resolve the issue, you want to determine which devices are likely causing the problems and, thus, require inspection first.
