Which of the following controls would stop attacks that are carried out by manipulating router route tables?

A.
Authentication

B.
ACLs

C.
Filters

D.
MICs

Explanation:
Hackers send ICMP messages to routers that contain status information.
This status information may indicate that a route is down or congested. Routers
accept these messages without requiring the sender to authenticate. If the router
required authentication, these types of attacks would not be successful.
