CCNP ENARSI PART 13

What are two features of BFD? (Choose two.). A. reliable. B. replaces hello messages. C. requires routing protocols. D. scalable. E. intensive on CPU for Layer 2 links.

What is the role of LDP in MPLS networks?. A. It creates MPLS packet forwarding along with the IGP routes. B. It enables label binding information to exchange with peer LSRs. C. It disables label binding information to exchange with peer LSRs. D. It enables label binding that exchanges route descriptors.

Which Layer 3 VPN attribute allows different customers to connect to the same MPLS network with overlapping IP ranges?. A. RT. B. RD. C. VRF. D. MP-BGP.

Refer to the exhibit. An engineer configured IP SLA to monitor a next hop on a router for reachability. When the next hop is unreachable, the router is executing tracking and falling over another route, but packet loss is experienced because the reachability is flapping. Which action resolves the issue?. A. Increase the frequency of the sla probe to 60. B. Append delay up 60 down 60 to the track command. C. Append delay up 0 down 0vto the track command. D. Increase the timeout of the sla probe to 6000.

Refer to the exhibit. The services at branch B are down. An engineer notices that router A and router B are not exchanging any routes. Which configuration resolves the issue on router B?. A. router eigrp 100 network 192.168.168.0 key-chain EIGRP key 1 key-string CCNP interface serial0/0/0 ip address 192.168.168.2 255.255.255.0 ip authentication key-chain eigrp 100 EIGRP negotiation auto. B. router eigrp 100 network 192.168.168.0 key-chain CCNP key 1 key-string EIGRP interface serial0/0/0 ip address 192.168.168.2 255.255.255.0 ip authentication mode eigrp 100 md5 ip authentication key-chain eigrp 100 EIGRP negotiation auto. C. router eigrp 100 network 192.168.168.0 key-chain EIGRP key 1 key-string CCNP interface serial0/0/0 ip address 192.168.168.2 255.255.255.0 ip authentication mode eigrp 100 md5 negotiation auto. D. router eigrp 100 network 192.168.168.0 key-chain EIGRP key 1 key-string CCNP interface serial0/0/0 ip address 192.168.168.2 255.255.255.0 ip authentication mode eigrp 100 md5 ip authentication key-chain eigrp 100 EIGRP negotiation auto.

What is the use of IPv6 snooping?. A. captures IPv6 routing protocol packets to analyze. B. requires an external IPv6 packet analyzer. C. required for the operation of IPv6 RA Guard. D. captures any type of user traffic to create a binding table.

Refer to the exhibit. An engineer must troubleshoot a connectivity issue impacting the redistribution of the subnet 172.16.2.48/28 into the OSPF domain. Which configuration on router R1 advertises this subnet into the OSPF domain?. A. R1(config)#route-map CCNP permit 10 R1(config-route-map)#match tag 200 R1(conflg-route-map)#exit - R1(config)#router ospf 10 - R1(config-router)#redistribute eigrp 100 subnets route-map CCNP. B. R1(config)#route-map CCNP deny 10 R1(conflg-route-map)#match tag 200 R1(config)#route-map CCNP permit 10 R1(config)#router ospf 10 - R1(conflg-router)#redistrlbute eigrp 100 subnets route-map CCNP. C. R1(config)#route-map CCNP permit 10 R1(config-route-map)#match route-type internal R1(config)#router ospf 10 - R1(config-router)#redistribute eigrp 100 subnets route-map CCNP. D. R1(config)#route-map CCNP permit 10 R1(config-route-map)#match route-type level-2 R1(config)#router ospf 10 - R1(config-router)#redistribute eigrp 100 subnets route-map CCNP.

Which feature drops packets if the source address is not found in the snooping table?. A. IPv6 Destination Guard. B. IPv6 Source Guard. C. Binding Table Recovery. D. IPv6 Prefix Guard.
