Cisco CCNP Service Provider 350-501 Questions & Answers

  • Question 111:

    Refer to the exhibit.

    A network engineer is implementing multicast Source-A to send a multicast stream for Receiver-A, and multicast Source-B to send a multicast stream for Receiver-B. Router RC forwards the IGMP host a report and leaves messages to IP address 192.168.10.1. How must the multicast features be implemented to prevent RB from receiving multicast flooding from Source-A?

    A. Change the helper-address value to 192.168.10.2 on RC.

    B. Enable ip pim neighbor-filter on RC interface Ge0/0.

    C. Configure PIM-SSM on RB and RC interface Ge 0/0.

    D. Enable ip pim passive on RB interface Ge0/0.

  • Question 112:

    Refer to the exhibit.

    Tier 2 ISP A on AS 653 is connected to two Tier 1 ISPs on AS 321 and AS 51 respectively. The network architect at ISP A is planning traffic flow inside the network to provide predictable network services. Cisco Express Forwarding is disabled on the edge router. How should the architect implement BGP to direct all traffic via the Tier 1 ISP with next-hop 7.4.5.2?

    A. Implement the BGP routing protocol and run the bgp deterministic-med command.

    B. Implement MP-BGP with a 4-byte AS number with the bgp best path compare-routerid command.

    C. Implement the BGP routing protocol and the maximum-paths 2 configuration.

    D. Implement BGP route-reflector functionality with the bgp always-compare-med configuration.

  • Question 113:

    Refer to the exhibit.

    A network administrator implemented MPLS routing between routers R1, R2, R3, and R4. AToM is configured between R1 and R4 to allow Layer 2 traffic from hosts on RA1 and RA2. A targeted MPLS session is established between R1 and R4. Which additional action must the administrator take on all routers so that LDP synchronization occurs between connected LDP sessions?

    A. Disable the MPLS LDP IGP sync holddown.

    B. Configure OSPF or IS-IS as the routing protocol.

    C. Configure EIGRP as the routing protocol using stub areas only.

    D. Enable MPLS LDP sync delay timers.

  • Question 114:

    While an engineer deploys a new Cisco device to redistribute routes from OSPF to BGP, they notice that not all OSPF routes are getting advertised into BGP. Which action must the engineer perform so that the device allows O, OIA, OE1, and OE2 OSPF routes into other protocols?

    A. Configure the device to pass only O and E2 routes through it.

    B. Configure the synchronization keyword in the global BGP configuration.

    C. Configure the keyword nssa in the redistribution entry.

    D. Configure the keywords internal and external in the redistribution entry.

  • Question 115:

    A company is expanding its existing office space to a new floor of the building, and the networking team is installing a new set of switches. The new switches are running IGMPv2, and the engineers configured them for VLAN10 only. The rest of the existing network includes numerous Layer 2 switches in multiple other VLANs, all running IGMPv3. Which additional task must the team perform when deploying the new switches so that traffic is switched correctly through the entire network?

    A. Configure the new switches to use IGMPv3 on all VLANs on the network.

    B. Configure all switches on the network to support IGMPv2 and IGMPv3 on all VLANs on the network.

    C. Configure the new switches to use IGMPv3 on VLAN10 only.

    D. Configure all switches on the network to support IGMPv2 and IGMPv3 on VLAN10 only.

  • Question 116:

    Refer to the exhibit.

    LDP peering between routers R1 and R2 is dropped when the link between R1 and R2 is taken offline. However, LDP peering between R2 and R3 stays up when the link between R2 and R3 is taken offline. Which action allows MPLS traffic forwarding to continue normally if the link between R1 and R2 goes down?

    A. Enable IGP and LDP Synchronization on R1.

    B. Implement LDP Session Protection on R1.

    C. Enable IGP and LDP Synchronization on R2.

    D. Implement LDP Session Protection on R2.

  • Question 117:

    Which type of attack is an application attack?

    A. ping of death

    B. ICMP (ping) flood

    C. HTTP flood

    D. SYN flood

  • Question 118:

    Refer to the exhibit.

    A network engineer observed congestion between routers R1 and R4, which are connected on a point-to-point link. Two servers that reside on networks on R1 and R4 generate heavy traffic between them with most traffic going from R4 to R1. To improve overall performance, the engineer wants to drop inbound packets that exceed a configured threshold, without disrupting traffic that passes from R4 to R3. Which action must the engineer take to resolve the issue?

    A. Implement traffic policing to drop packets that exceed the given threshold.

    B. Implement FIFO to queue excess traffic for transmission when bandwidth is available.

    C. Implement traffic shaping to drop excess packets.

    D. Implement a service policy in the outbound direction on each interface on the link to tag traffic exiting each router.

  • Question 119:

    Refer to the exhibit A user is performing QoS marking on internet traffic and sending it with IPv4 and IPv6 headers on the provider edge device PE1. IPv4 traffic is classified with DSCP 4 and IPv6 traffic is classified with DSCP 6. Which action must the engineer take to begin implementing a QoS configuration on PE1 for the IPv6 traffic?

    A. Create an access list that includes any IPv6 traffic and apply it to CM-20.

    B. Create access list IPv6-match and configure match ip dscp 4 and match ip dscp 6 in class maps CM-10 and CM-20.

    C. Configure match ip dscp 4 in class map CM-10 and match ip dscp 6 in class map CM-20.

    D. Create access list IPv6-filter and remove DSCP value 4 and 6 in class maps CM-10 and CM-20.

  • Question 120:

    Refer to the exhibit.

    EIGRP is running between routers R5 and R1, and OSPF is used in the rest of the network. Users in a network attached to router R3 need to access a server connected to R5. Which task must the engineer perform so that only the users attached to R3 are able to access the server, but no other network is shared to OSPF?

    A. Configure redistribution using route maps to filter the routes that are shared

    B. Configure redistribution using an offset list to filter the routes that are shared.

    C. Configure an OSPF virtual link between R1 and R3 to route traffic between the two areas.

    D. Configure R1 as a stub router for EIGRP and OSPF so that only the default route is shared
