1.
Which security implementation will provide control plane
protection for a network device?
o A.
Encryption for remote access connections
o B.
AAA for authenticating management access
o C.
Routing protocol authentication
o D.
NTP for consistent timestamps on logging messages
Correct Answer
C. Routing protocol authentication
Explanation
Routing protocol authentication is a security implementation that
provides control plane protection for a network device. It ensures that
only authorized routers can participate in the routing process by
verifying the authenticity of routing updates. This prevents unauthorized
devices from injecting false routing information and helps in protecting
the network against attacks such as route poisoning or route hijacking.
By authenticating the routing protocol, the control plane of the network
device is protected, enhancing the overall security of the network.
