What will be the preference of these two routes? Assume that all IS-IS routers are L1/L2 capable and are in the same area. Choose two answers.
- A . The OSPF internal preference
- B . The IS-IS Level 1 internal preference
- C . The IS-IS Level 2 internal preference
- D . The OSPF external preference
- E . The IS-IS Level 2 external preference
- F . The IS-IS Level 1 external preference

Which of the following statements best describes the function of an OSPF Type 4 LSA?
- A . A Type 4 LSA is originated by an ABR to describe a route to an ASBR to routers outside the area.
- B . A Type 4 LSA is originated by an ASBR to describe a route to itself to routers outside the area.
- C . A Type 4 LSA is originated by an ABR that is connected to a stub area. The LSA is injected into the backbone area to provide routing information.
