Question:
When troubleshooting Ethernet connectivity issues, how can you verify that an IP address is known to a router?

• Check whether the IP address is in the routing table
• Check whether an ACL is blocking the IP address
• Check whether the IP address is in the CAM table
• Check whether the IP address is in the ARP table

Explanation: If the IP address exists in the routing table then we can say the local router knew the way to reach that destination. But this question wants to ask if the destination has communicated to the local router or not (“an IP address is known to a router”). Maybe it is a tricky question.
