Which statement is true about CDP on a Cisco device? Because it runs at the data link layer, the CDP protocol can only be implemented in switches. The show cdp neighbor detail command will reveal the IP address of a neighbor only if there is Layer 3 connectivity. CDP can be disabled globally or on a specific interface. To disable CDP globally, the no cdp enable command in interface configuration mode must be used.
CDP can be disabled globally or on a specific interface.

A technician is troubleshooting a network problem. After troubleshooting, the technician concludes that a switch should be replaced. What should the technician do next? Email all users to let them know they are replacing a switch. Escalate the trouble ticket to the manager to approve the change. Purchase a new switch and replace the defective one. Resolve the problem.
Escalate the trouble ticket to the manager to approve the change.
A small company has only one router as the exit point to its ISP. Which solution could be adopted to maintain connectivity if the router itself, or its connection to the ISP, fails? Have a second router that is connected to another ISP. Add more interfaces to the router that is connected to the internal network. Purchase a second least-cost link from another ISP to connect to this router. Activate another router interface that is connected to the ISP, so the traffic can flow through it.
