1. Question 481 · 578 in bank

   

   Refer to the exhibit. In Cisco DNA Center, a network engineer identifies that BGP-learned networks are repeatedly withdrawn from peers. Which configuration must the engineer apply to resolve the issue?

   

   • Arouter bgp 100 bgp dampening
   • Brouter bgp 100 bgp graceful-restart
   • Croute-map Dampening permit 10 set dampening 15 750 2000 60 router bgp 100 neighbor 10.140.212.5 route-map Dampening out
   • Droute-map Dampening permit 10 set dampening 15 750 2000 60 router bgp 100 neighbor 10.140.212.5 route-map Dampening in

   Show answer

   Answer: A

   Explanation

   I will go with "A" just because of "from peers" so not a single peer/route plus, while "D" has the config correct, but we dont know if that flapping happening only on that one single neighbor

3. Question 483 · 578 in bank

   Which router takes an active role between two LDP neighbors when initiating LDP session negotiation and LDP TCP connection establishment?

   • Awith one interface in the MPLS backbone
   • Bwith the higher IP address
   • Cwith the lowest IP address
   • Dwith the larger number of LDP TCP neighbors

   Show answer

   Answer: B

   Explanation

   This is correct. https://www.cisco.com/en/US/docs/ios-xml/ios/mp_ldp/configuration/15-2s/mp-ldp-overview.html To initiate an LDP session between routers, the routers determine which router will take the active role and which router will take the passive role. The router that takes the active role establishes the LDP TCP connection session and initiates the negotiation of the LDP session parameters. To determine the roles, the two routers compare their transport addresses. The router with the higher IP address takes the active role and establishes the session.

6. Question 486 · 578 in bank

   

   Refer to the exhibit. Which action adds the 10.1.7.6/32 route to the BGP table?

   • AAdd a static route for the 10.1.7.6/32 network.
   • BAdd summary-address 10.1.7.6 255.255.255.0.
   • CAdd the network 10.1.7.6 mask 255.255.255.255 backdoor command.
   • DAdd the network 10.1.7.6 mask 255.255.255.255 command.

   Show answer

   Answer: D

   Explanation

   This one looks to be correct. Loopback6 has IP: 10.1.7.6. So adding the network 10.1.7.6 mask 255.255.255.255 command will create an entry in the routing table for 10.1.7.6/32

7. Question 487 · 578 in bank

   A network engineer must configure an EIGRP stub router at a site that advertises only connected and summary routes. Which configuration performs this task?

   • Arouter eigrp 100 eigrp stub redistribute
   • Brouter eigrp 100 eigrp stub
   • Crouter eigrp 100 eigrp stub connected
   • Drouter eigrp 100 eigrp stub summary

   Show answer

   Answer: B

   Explanation

   The correct answer is B because the eigrp stub command, by default, advertises only connected and summary routes. This meets the requirement. A allows redistribution of routes. C only advertises connected routes. D only advertises summary routes.

   Refer to the exhibit. A network engineer configured routers R1 and R2 with MP-BGP. The engineer noticed that the routers cannot exchange any IPv6 routes; however, the IPv4 neighbor relationship is working fine. Which configuration must the engineer apply to router R2 to exchange IPv6 routes?

   • Aipv6 unicast-routing ipv6 cef ! interface Loopback100 ipv6 address 2001:DB8:128::2/128 ! interface GigabitEthernet1/0 ipv6 address 2001:DB8:1::2/64 ! router bgp 65002 no bgp default ipv4-unicast neighbor 2001:DB8:1::1 remote-as 65001 ! address-family ipv4 network 2001:DB8:128::2/128

   Answer: C

   Explanation

   Correct. It is the only option were this below is included. ipv6 unicast-routing ipv6 cef ______ ______ ______ address-family ipv6 network 2001:DB8:128::2/128 neighbor 2001:DB8:1::1 activate And of course the other commands in option C are correct.

9. Question 489 · 578 in bank

   

   Refer to the exhibit. Which configuration command establishes an EIGRP neighbor adjacency between the hub and spoke?

   • Anetwork 10.1.2.192 command on spoke router
   • Bnetwork 10.1.2.192 command on hub router
   • Ceigrp-peer 10.1.2.192 command on hub router
   • Dconnected 10.1.2.192 command on spoke router

   Show answer

   Answer: B

   Explanation

   The 'Neighbor not yet found' means that you are receiving updates, queries, or replies from an EIGRP router on this link, but the router does not recognize the sender as a valid neighbor https://www.cisco.com/c/en/us/support/docs/ip/enhanced-interior-gateway-routing-protocol-eigrp/118974-technote-eigrp-00.html

10. Question 490 · 578 in bank

    

    Refer to the exhibit. An engineer wanted to set a tag of 30 to route 10.1.80.65/32 but it failed. How is the issue fixed?

    • AModify route-map ospf-to-eigrp permit10 and match prefix-list ccnp2.
    • BModify prefix-list ccnp3 to add 10.1.64.0/20 ge 32.
    • CModify prefix-list ccnp3 to add 10.1.64.0/20 le 24.
    • DModify route-map ospf-to-eigrp permit 30 and match prefix-list ccnp2.

    Show answer

    Answer: A

    Explanation

    correct answer is A. 10.1.80.65/32 needed to add tag 30 so we must modify route-map ospf-to-eigrp permit 10 to match ip prefix-list ccnp2
