What are two reasons to enable OSPF routing protocol authentication on a network? (Choose two.)
- to prevent data traffic from being redirected and then discarded
- to ensure faster network convergence
- to provide data security through encryption
- to prevent redirection of data traffic to an insecure link
- to ensure more efficient routing
Explanation: The reason to configure OSPF authentication is to mitigate against routing protocol attacks like redirection of data traffic to an insecure link, and redirection of data traffic to discard it. OSPF authentication does not provide faster network convergence, more efficient routing, or encryption of data traffic.
