Map the Network from SR-WKS-118

It's your first week on the bench at Saltmarsh Robotics. Before you change anything, your lead wants you to learn the network the safe way — by reading it. From the workstation SR-WKS-118, use the built-in command-line tools to find your way out to the gateway, confirm which of the two external resolvers is actually answering, and trace the path to the Harborview partner site. Type your commands in the console, watch the checklist fill in, then answer the questions.

What IPv4 address is set as this workstation's default gateway?

In your trace to the partner host 192.0.2.80, how many hops did it take to reach the destination?

One of the two external resolvers returned 100% packet loss. Which IP address failed to reply?

Hop 3 of the trace showed Request timed out. yet the trace still reached 192.0.2.80. What is the most likely explanation?

The destination host is unreachable. That router forwarded the packet but didn't answer the probe itself. The workstation's default gateway is misconfigured. DNS name resolution failed for the partner site.
