What type of OSPF router generates a type 2 LSA?
- A . Area Border Router
- B . Autonomous System Boundary Router
- C . Designated Router
- D . All routers within an OSPF area.
Select the answer below that correctly lists the 5 different OSPF packet types.
- A . Hello, Link State Update, Link State Packet, Link State Acknowledgement, Database Descriptor
- B . Link State Update, Link State Refresh, Link State Acknowledgement, Database Descriptor, Notification
- C . Hello, Link State Refresh, Link State Update, Link State Acknowledgement, Link State Authentication
- D . Hello, Link State Update, Link State Request, Link State Acknowledgement, Database Descriptor
A router receives an OSPF database description packet from a neighbor that references an LSA, which is already in the router's LSDB.The sequence number in the DBD packet is lower than the sequence number of the LSA in the LSDB. What action does the router take?
- A . The router sends a link-state update to its neighbor.
- B . The router sends a link-state acknowledgement to its neighbor.
- C . The router updates the information in its LSDB with the information received from its neighbor.
- D . The router sends a link-state request to its neighbor.
- E . The router takes no action.
What is the metric and maximum routable value for RIP?
- A . Hop count and 16
- B . Hop count and 15
- C . Link cost and 15
- D . Link cost and 16

- A . 224.0.0.5
- B . 224.0.0.6
- C . 224.0.0.9
- D . 224.0.0.10
- E . RIPv2 does not have support for multicast
What are some of the characteristics of Nokia’s implementation of non-stop routing? (Choose two)

Choose the Distance Vector Protocols from the list below:
- A . OSPF
- B . RIPv1
- C . RIPv2
- D . IS-IS
Click on the exhibit.
Router R2 learns the networks shown from IS-IS.Router R2 is configured to redistribute routes from IS-IS to OSPF as shown.Assume the OSPF and IS-IS adjacencies are operational.

- A . 0
- B . 1
- C . 2
