While investigating questionable traffic, a shipping company discovered that some routes between branch and distribution facilities were overshadowed, permitting unauthorized infiltration. Which action reduces this security risk?
Block incoming data from the distribution site
Add a domain suffix on the branch routers
Raise the TTL to mitigate counterfeited routes
Enable routing protocol authentication to validate updates
Enabling routing protocol authentication ensures route advertisements are validated, preventing outsiders from manipulating or overshadowing a legitimate path. Adding a domain suffix does not strengthen route integrity, raising the TTL does not address counterfeit routes, and blocking incoming data fails to remove malicious route influences.
