Cisco 300-510 Online Questions & Answers

  • Question 81:

    Refer to the exhibit.

    OSPF is an interior routing protocol on the network. R2 is in the backbone area, and R4 is in a totally NSSA area. R5 announces only the 0.0.0.0/0 route to R4 via BGP. R4 is configured with redistribute bgp 736 metric-type 2. After the most

    recent maintenance window, R2 no longer has the default route via R4.

    Which action must the network engineer take to correct the reachability problem?

    A. Configure area 2 nssa no-summary under the global router configuration on router R2.
    B. Configure default-information-originate under the OSPF configuration on router R4.
    C. Configure ip route 0.0.0.0 0.0.0.0 null0 under the global router configuration on router R4.
    D. Configure area 2 nssa translate type7 no-suppress-fa under the OSPF configuration on router R2.

  • Question 82:

    Refer to the exhibit.

    A network engineer must enable segment routing between the three autonomous systems with these requirements:

    OSPF link-state data for area 0 routers must be distributed to the controller via BGP LS.

    Routers must advertise peer node SIDs to the controller R1 via BGP LS.

    D. R2(config)# router ospf 100 R2(config-ospf)# distribute link-state instance-id 100 throttle 10 R2(config)# router bgp 100 R2(config-bgp)# neighbor 10.10.20.1 R2(config-bgp-nbr)# remote-as 300 R2(config-bgp-nbr)# egress-engineering R2(config-bgp-nbr)# neighbor 192.168.20.1 R2(config-bgp-nbr)# remote-as 100 R2(config-bgp-nbr)# address-family link-state link-state

  • Question 83:

    DRAG DROP

    An engineer is troubleshooting end-to-end customer traffic across an MPLS VPN service provider network.

    Which tasks should the engineer use to solve the routing issues?

    Drag and drop the table types from the left onto the most useful troubleshooting tasks/router types on the right. (Not all options are used.)

    Select and Place:

  • Question 84:

    Refer to the exhibit.

    After configuring IS-IS on routers R1 and R2, an engineer notices that only the loopback interface at 2000:1::1 /96 is known to router R2. Which change must be made so that only Loopback2 is advertised from R1 to R2?

    A. Configure the router isis area1 command under the Loopback0 interface on R1.
    B. Remove the advertise passive-only command under the IS-IS address family ipv6 configuration
    C. Remove the ipv6 router isis area1 command under the Loopback2 interface on R1.
    D. Remove the passive-interface Loopback0 command under the router isis area1 configuration.

  • Question 85:

    Which fact must a network architect consider when implementing IGMP in a multicast routing environment?

    A. If SSM is in use, IGMPv3 must be enabled.
    B. If BISS support is required, IGMPv2 must be enabled.
    C. If leave latency is critical, IGMPv3 must be enabled.
    D. If PIM-DM is required, IGMPv2 must be enabled.

  • Question 86:

    Refer to the exhibit.

    A network engineer is configuring router R3 to handle multicast streams, but Host-2 cannot send subscriptions messages to the IPTV source.

  • Question 89:

    Refer to the exhibit.

    The four routers in this network have formed adjacencies. Router R2 is an IS-IS Level 1-2 router that connects to other areas, and the attach bit is set in R2's Level 1 LSP advertisements to R1. According to the network design, R2 should push Level 2 routes from its routing table to R1's routing table. However, R1 installed a default route in its routing table. Which action resolves this problem?

    A. Use the is-type level-1-2 backdoor command to unset the attach bit on R1, and use a prefix list to filter prefixes from R2.
    B. Set the attach bit on R1 and use a prefix list to filter prefixes from R2.
    C. Use the is-type level-1-2 backdoor command to unset the attach bit on R2 and configure a distribute-list to redistribute prefixes to R1.
    D. Configure R2 as a Level 1 router and use a prefix list to filter prefixes to R1.

  • Question 90:

    Refer to the exhibit.
