NEW QUESTION # 17
Refer to the exhibit. Routers R1 and R2 reside in AS 65530, which is multihomed to the Internet.

- A. Remove the neighbor statements from the address family configuration and activate the neighbor globally on R1.
- B. Change the route map direction in the neighbor statement to out.
- C. Add a sequence number to the route map to remove the implicit deny.
- D. Configure the route map with a local preference of 200 or higher.

NEW QUESTION # 18
Which multicast routing protocol is most optimal for supporting many-to-many multicast applications?
- A. MSDP
- B. PIM-SM
- C. PIM-BIDIR
- D. MP-BGP
- E. DVMRP
Answer: C
Explanation:
PIM-Bidirectional Operations
PIM Bidirectional (BIDIR) has one shared tree from sources to RP and from RP to receivers.
This is unlike the PIM-SM, which is unidirectional by nature with multiple source trees - one per (S, G) or a shared tree from receiver to RP and multiple SG trees from RP to sources.
Benefits of PIM BIDIR are as follows:
As many sources for the same group use one and only state (*, G), only minimal states are required in each router.
No data triggered events.
Rendezvous Point (RP) router not required.
The RP address only needs to be a routable address and need not exist on a physical device.
NEW QUESTION # 19
An engineer warns to map a multicast IP address to a multicast MAC How many bits are used to make the conversion?
- A. high-order 24 bits
- B. higher-order 23 bits
- C. lower-order 24 bits
- D. low order 23 bits
Answer: D
NEW QUESTION # 20
Refer to the exhibit.
Routers RA and RB are IS-IS peers configured for NSF but router RC is an IS-IS peer without NSF capability If RA undergoes processor switchover what is the effect on the network environment?
- A. If RC is operating without the Cisco configuration option all three routers tear down their peering relationships and re-establish peering
- B. If RC is operating without the Cisco configuration option only 2 routers tear down their peering relationships and re-establish peering
- C. All peer relationships remain up and the link-state database is unchanged
- D. All peer relationships remain up, but the link-state database is rebuilt on each device
Answer: D
NEW QUESTION # 21
Refer to the exhibit.
An engineer is troubleshooting connectivity issues on the MPLS core network. A customer connected through R4 cannot reach the OSPF domain on R5. While checking the routing table of R1, the engineer cannot see all the routes from R3 and R5. Which task must the engineer perform so that R4 is able to reach R5?
- A. Enable MP-BGP peering on routers R1. R3, R4, and R5.
- B. Enable OSPF on the Area-0 routers and configure MP-BGP between routers R1 and R3.
- C. Enable OSPF peering and configure route redistribution between routers R4 and R1.
- D. Enable route filtering between routers R1 and R3.
Answer: C
NEW QUESTION # 22
What is the difference between RPL and route map actions?
- A. RPL uses match, pass, set, and drop actions, and route maps use match, set, and drop actions.
- B. RPL uses match, set, drop, and stop actions, and route maps use match, set, and drop actions
- C. RPL uses pass, set, and drop actions only, and route maps use match, set, and drop actions.
- D. RPL uses pass, set, drop, and done actions, and route maps use match and set actions only.
