• Question 11:

  You were provided a network diagram that told you to number your network from the 191.255.0.0/16 space. OSPF is enabled and adjacencies are up, but no routers are learning any routes. What can explain this?

  A. The default OSPF export policies advertise nothing, so you need to apply export policy
  B. The default OSPF import policy rejects all OSPF routes, so you need to apply import policy
  C. You need to modify the martian table with a 191.255.0.0/16 accept statement
  D. You need to enable OSPF on the lo0 interface to provide a route to the RID of each router in the network
  C. You need to modify the martian table with a 191.255.0.0/16 accept statement

• Question 13:

  If an EX Series switch receives a frame with a known destination MAC address, what is the expected behavior?
