Cisco 300-510 Online Questions & Answers

• Question 211:

  Refer to the exhibit.

  

  XR1 and XR2 are sending the prefix 10.11.11.0/24 to XR3. A configured policy on XR1 is incorrectly prepending AS path 11 11 12 12 onto this prefix. A network operator wants to add a policy onto XR3 that will not allow the falsely prepending prefix from being installed.

  Which policy configuration applied to the XR3 neighbor configuration for XR1 can accomplish this requirement without impact to other or future received routes?

  

  A. Option A
  B. Option B
  C. Option C
  D. Option D
  D. Option D

• Question 213:

  Refer to the exhibit.

  

  Refer to the exhibit. The initial BGP configuration of the network is complete, and all the routers have established BGP neighborship. The engineer configured Router 2 with additional BGP paths to install and advertise more paths to Router 1

  and Router 3.

  A. router bgp 65005 address-family ipv4 bgp additional-paths select all
  B. router bgp 65005 address-family ipv4 neighbor 2.2.2.2 additional-paths receive bgp additional-paths select all bgp additional-paths all
  C. router bgp 65005 address-family ipv4 bgp additional-paths select all bgp additional-paths install
  D. router bgp 65005 address-family ipv4 neighbor 2.2.2.2 additional-paths receive bgp additional-paths select all bgp additional-paths install
  D. router bgp 65005 address-family ipv4 neighbor 2.2.2.2 additional-paths receive bgp additional-paths select all bgp additional-paths install

• Question 214:

  Which feature provides service independence in service provider networks?

  A. node SID that identifies the network device
  B. prefix SID that contains router hops toward the destination
  C. adjacency SID that represents a path between the routers
  D. binding SID that is used to stitch different domains
  A. node SID that identifies the network device

  SIMULATION

  Guidelines

  This is a lab item in which tasks will be performed on virtual devices.

  1. Refer to the Tasks tab to view the tasks for this lab item.

  2. Refer to the Topology tab to access the device console(s) and perform the tasks.

  3. Console access is available for all required devices by clicking the device icon or using the tab(s) above the console window.

  4. All necessary preconfigurations have been applied.

  5. Do not change the enable password or hostname for any device.

  6. Save your configurations to NVRAM before moving to the next item.

  7. Click Next at the bottom of the screen to submit this lab and move to the next question.

  8. When Next is clicked, the lab closes and cannot be reopened.

  Topology

  

  Tasks

  Troubleshoot and configure OSPF according to the topology to achieve these goals:

  1. R1 and R2 must not have OSPF BR/DR election over their E0/0 interfaces and must not advertise the OSPF host route for the OSPF connected neighbors.

  2. E0/0 interfaces on R1 and R2 to be preferred over E0/1 interfaces for OSPF traffic. Only the numerical value of 15 is allowed.

  3. Set the OSPF hello interval to 5 and the OSPF dead interval to 10 between R1 and R2 on interface E0/1.

  A. Check the answer in the explanation
  B. Placeholder
  C. Placeholder
  D. Placeholder
  A. Check the answer in the explanation

• Question 218:

  Refer to the exhibit.

  

  All backbone interfaces on the network are in VRF_MPLS, and ip rsvp signaling hello is preconfigured on all MPLS routers in the network. After router R2 was upgraded and its configuration restored from backup, the LSP signaled via RSVP that the tunnel from R1 had been torn down. The network engineer confirmed IP reachability in the backbone network. Which action must the engineer take to fix the issue?

  A. Configure ip rsvp udp neighbor 172.16.10.1 vrf VRF_MPLS under the global configuration on R2.
  B. Configure ip rsvp listener outbound reply 172.16.10.1 vrf VRF_MPLS under the global configuration on R2.
  C. Configure ip rsvp signaling hello refresh interval 20 under the interface Gi0/0 configuration on R1.
  D. Configure ip rsvp udp-multicast 172.16.10.2 vrf VRF_MPLS under the interface Gi0/0 configuration on R1.
  C. Configure ip rsvp signaling hello refresh interval 20 under the interface Gi0/0 configuration on R1.

• Question 219:

  Refer to the exhibit.

  

  An engineer applied the summarization configuration on R1 for four networks (192.168.20.0/24 to 192.168.23.0/24) in area 1 and eight networks (192.168.32.0/24 to 192.168.39.0/24) in area 2 to stop the flooding of all the customer routes. While checking the routing table of R2, the engineer noticed that R1 is still sending only specific routes to R2. Which configuration should the engineer apply on R1 to summarize routes?

  

  A. Option A
  B. Option B
  C. Option C
  D. Option D
  D. Option D
