Routers R1 and R2 are in different areas,

B.

Routers R1 and R2 are in the same area.

C.

Routers R1 and R2 will send a Level 1 Hello PDU and Level 2 Hello PDU, if the interface type between them is point-to-point.

D.

Routers R1 and R2 will send a Level 1 Hello PDU and Level 2 Hello PDU, if the interface type between them is broadcast.

Routers R1 and R2 will send a Level 1/2 Hello PDU, if the interface type between them is broadcast.

Which of the following statements regarding IS-IS DIS is false?

A.

L1 and L2 routers elect separate DIS's.

B.

DIS uses multicast address 0180x200:0015 to communicate with other routers on the broadcast network.

A.

A packet with a destination anycast address is sent to all nodes on the local link.

B.

A packet with a destination anycast address is sent to all nodes on the local network.

C.

A packet with a destination anycast address is sent to all nodes that have joined the anycast group.

D.

Which of the following statements regarding OSPF routing updates on a point-to-point link is true?

A.

On a point-to-point link, there is no need for a DR and BDR election; all routing updates are sent to 224.0.0.5.

B.

On a point-to-point link, a DR and BDR are elected. The DR sends link-state advertisements describing the network.

On a point-to-point link, a DR and BDR are elected. To ensure resiliency, both the DR and BDR send link-state advertisements describing the network.

D.

On a point-to-point link, there is no need for a DR and BDR election. All routing updates are sent to the unicast address of the neighbor's interface.
