   A service provider is experiencing a DDoS attack targeting a customer's public web server. The attack traffic is sourced from many different IPs but always targets TCP port 443 on the customer's server. The provider wants to drop this traffic at the edge router without impacting legitimate traffic to other destinations. The edge router has an established iBGP session with a route reflector. What should the provider configure on the edge router?

   • AA static route for the customer's server IP with a next-hop of discard, redistributed into BGP.
   • BA firewall filter applied to the loopback interface matching source port 443 and discarding the traffic.
   • CA routing policy applied to the iBGP session that sets the next-hop to a blackhole route for the customer's prefix.
   • DA BGP Flowspec route matching destination port 443 with a discard action, advertised to the route reflector.
