The interface facing the neighbor is down.

C.

The interface is included in a different area than the neighbor router.

D.

The router has not received a valid OSPF Hello packet from its neighbor.

Which three IS-IS PDU types are used for database synchronization?

A.

Hellos, CSNPs, PSNPs

B.

LSPs. Hellos, CSNPs

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.

D.

A Type 4 LSA is originated by an ABR that is connected to a stub area. The LSA is injected into the stub area to provide routing information.

C.

To allow interdomain routing between an IGP and EGP such as OSPF and BGP.

D.

To simplify the allocation of IP address space by defining a fixed size for the network portion of the address for each of the address classes.
