Which security implementation will provide control plane protection for a network device?
- encryption for remote access connections
- AAA for authenticating management access
- routing protocol authentication
- NTP for consistent timestamps on logging messages
Explanation: Control plane traffic such as ARP messages or routing protocol advertisements are generated by a network device in order to support network operations. Routing protocol authentication provides an extra measure of security to authenticate the source of routing updates. Encrypting remote access connections, utilizing the NTP protocol, and using AAA, are all measures implemented to secure management plane traffic.
