Cisco CCNP Enterprise 300-410 Questions & Answers

• Question 821:

  Refer to the exhibit. After redistribution is enabled between the routing protocols; PC2, PC3, and PC4 cannot reach PC1.

  Which action can the engineer take to solve the issue so that all the PCs are reachable?

  

  A. Set the administrative distance 100 under the RIP process on R2.

  B. Filter the prefix 10.1.1.0/24 when redistributed from OSPF to EIGRP.

  C. Filter the prefix 10.1.1.0/24 when redistributed from RIP to EIGRP.

  D. Redistribute the directly connected interfaces on R2.

  Correct Answer: A

  This Config works: Answer A

  R2#sh run | s rip redistribute rip metric 1 1 1 1 1 router rip version 2 redistribute eigrp 100 metric 1 network 10.0.0.0 network 12.0.0.0 distance 100 no auto-summary

  R3#sh run | s router router eigrp 100 network 34.34.34.0 0.0.0.255 redistribute ospf 100 metric 1 1 1 1 1 router ospf 100 redistribute eigrp 100 subnets network 10.3.3.0 0.0.0.255 area 0 network 23.23.23.0 0.0.0.255 area 0

  Answer B is wrong: the Correct is to filter 10.1.1.10 when redistribute from EIGRP to OSPF: Configs are

  ip prefix-list DNA seq 5 deny 10.1.1.0/24 ip prefix-list DNA seq 10 permit 0.0.0.0/0 le 32 route-map DDD permit 10 match ip address prefix-list DNA ! router eigrp 100 network 34.34.34.0 0.0.0.255 redistribute ospf 100 metric 1 1 1 1 1 ! router ospf 100 redistribute eigrp 100 subnets route-map DDD network 10.3.3.0 0.0.0.255 area 0 network 23.23.23.0 0.0.0.255 area 0 !

• Question 823:

  Refer to the exhibit. After applying IPsec, the engineer observed that the DMVPN tunnel went down, and both spoke-to-spoke and hub were not establishing. Which two actions resolve the issue? (Choose two.)

  

  A. Change the mode from mode tunnel to mode transport on R3.

  B. Remove the crypto isakmp key cisco address 10.1.1.1 on R2 and R3.

  C. Configure the crypto isakmp key cisco address 192.1.1.1 on R2 and R3.

  D. Configure the crypto isakmp key cisco address 0.0.0.0 on R2 and R3.

  E. Change the mode from mode transport to mode tunnel on R2.

  Correct Answer: BD

• Question 824:

  Which statement about route distinguishers in an MPLS network is true?

  A. Route distinguishers allow multiple instances of a routing table to coexist within the edge router.

  B. Route distinguishers are used for label bindings.

  C. Route distinguishers make a unique VPNv4 address across the MPLS network.

  D. Route distinguishers define which prefixes are imported and exported on the edge router.

  Correct Answer: C

• Question 825:

  Refer to the exhibit. What is the result of applying this configuration?

  

  A. The router can form BGP neighborships with any other device.

  B. The router cannot form BGP neighborships with any other device.

  C. The router cannot form BGP neighborships with any device that is matched by the access list named "BGP".

  D. The router can form BGP neighborships with any device that is matched by the access list named "BGP".

  Correct Answer: C

  After bgp session are UP.I configured the CoPP to drop 10.3.3.3 bgp traffic (R3). R3 bgp traffic that matched the ACL 100 is dropped and the state is in IDLE ----------------------------? access-list 100 permit tcp host 10.3.3.3 any eq bgp access-list 100 permit tcp host 10.3.3.3 eq bgp any ! class-map match-all class-bgp match access-group 100 !

  policy-map policy-bgp class class-bgp drop ! control-plane service-policy input policy-bgp ! The 10.3.3.3 neighbor goes to IDLE

• Question 826:

  C. show run vrf

  D. show ip protocols vrf

  Correct Answer: B
