And now... the answers!
1. "C". BPDU Guard will shut a port down that receives any kind of BPDU, whether inferior or superior.
2. "B". Of the three EIGRP tables, the feasible successor is found only in the Topology table. The successor is found in both the Route and Topology tables.
3. We're using a standard ACL, so the line will be access-list 45 permit any.
4. "C". With a /16 network, the wildcard mask we use with OSPF will be 0.0.255.255.
Thanks for taking today's practice exam, and I'll see you on YouTube and Udemy!
