What represents a best practice concerning discovery protocols such as CDP and LLDP on network devices?

  • Enable CDP on edge devices, and enable LLDP on interior devices.
  • Use the open standard LLDP rather than CDP.
  • Use the default router settings for CDP and LLDP.
  • Disable both protocols on all interfaces where they are not required.

Explanation: Both discovery protocols can provide hackers with sensitive network information. They should not be enabled on edge devices, and should be disabled globally or on a per-interface basis if not required. CDP is enabled by default.
