What represents a best practice concerning discovery protocols such as CDP and LLDP on network devices?
- Use the open standard LLDP rather than CDP.
- Disable both protocols on all interfaces where they are not required.
- Use the default router settings for CDP and LLDP.
- Enable CDP on edge devices, and enable LLDP on interior devices.
Answers Explanation & Hints:
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.
