- C. Ethernet frames sent to an Ethernet multicast address.
- D. IP packets sent to an IP unicast address.
Answer: A
NEW QUESTION # 56
When redistributing OSPF into RIP V2 what must be taken into consideration for the redistribution to take place?
- A. The metric must be set accordingly for RIP
- B. You must divide the cost of the OSPF route by three
- C. The router must be configured as an ASBR
- D. The subnet mask must be removed from the OSPF route
Answer: A
NEW QUESTION # 57
What is the source IP address in an OSPF update?
- A. 224.0.0.6
- B. 224.0.0.5
- C. The system address of the router
- D. The unicast IP address of the interface the update is being sent on.
Answer: D

The OSPF packets shown have been exchanged between two neighbors. What state is the OSPF adjacency in?
- A. The adjacency state is two way because both routers have received a database description packet.
- B. The adjacency is in the exchange state. The next step is to exchange link state request and link state update packets.
- C. The adjacency is in the ex start state. The routers have exchanged database description packets, but still have to negotiate the starting sequence number.
- D. The adjacency state is full. The routers are exchanging database description packets to notify each other that all link state advertisements have been received.
Answer: C

If router R2 redistributes the IS-IS route to 192.168.3.0/24 into OSPF, router R3 preference of these two routes? Choose two answers.
- A. The IS-IS Level 1 external preference
- B. The IS-IS Level 2 external preference
- C. The IS-IS Level 2 internal preference
- D. The OSPF external preference
- E. The IS-IS Level 1 internal preference
- F. The OSPF internal preference
Answer: D,E
NEW QUESTION # 60
Refer to the exhibit.
Assume that OSPFv3 is properly configured on all routers and that R4 advertises its system prefix into Area 0. Which of the following statements best describes how R5 learns R4's IPv6 system prefix?
- A. With an Inter-Area Prefix LSA originated by R4
- B. With a Router LSA originated by R5
- C. With an Inter-Area Prefix LSA originated by R1
- D. With an Inter-Area Prefix LSA originated by R5
- E. With a Router LSA originated by R4
- F. With a Router LSA originated by R1
Answer: C
NEW QUESTION # 61

What triggers convergence of the routing protocol when the link between switch 1 and switch 2 goes down?
- A. Convergence will not be triggered because switches cannot run routing protocols between them.
- B. Convergence is triggered when the switches notify the routers about the link state information. At this point, both routers R1 and R2 re-compute their link state database and send updates to their adjacent routers. Once the process is complete for all routers, the networks have converged
- C. Convergence is triggered when the physical interfaces between routers R1 and R2 go down. At this point, both routers R1 and R2 re-compute their link state database and send updates to their adjacent routers. Once the process is complete for all routers, the networks have converged.
- D. Convergence is triggered when an LSA is sent from router R1 to router R2 to indicate that the link is down. At this point, both routers R1 and R2 re-compute their link state database and send updates to their adjacent routers. Once the process is complete for all routers, the networks have converged.
- E. Convergence is triggered when the adjacency between routers R1 and R2 drops as a result of Hello timeouts. At this point, both routers R1 and R2 re-compute their link state database and send updates to their adjacent routers. Once the process is complete for all routers, the networks have converged.
Answer: E
NEW QUESTION # 62

NEW QUESTION # 64
Which of the following statements apply to link state protocol behavior? Choose three answers.
- A. Routers broadcast the entire route table to all neighbors.
- B. Information about directly connected links is sent to all neighbors.
- C. An adjacency database is maintained by each router.
- D. The sequence number for an update is incremented as it is flooded from router to router.
- E. The topological database is the same for all routers in a single area.
Answer: B,C,E
NEW QUESTION # 65

Answer: D
NEW QUESTION # 66
What causes an adjacency to change from "Init" to "Two Way"?
- A. When a Link State Update is received in response to a Link State Request
- B. When a Link State Acknowledgement is received in response to a Link State Update
- C. When OSPF neighbors exchange Database Descriptor packets
- D. When a router receives a Hello packet from a neighbor that contains its router id in the neighbor list
Answer: D
NEW QUESTION # 67
