Demo Questions

Question 1
Refer to the exhibit. In this BGP setup, 10.1.1.0/24 is advertised by AS 400 to its peers. Border routers in AS 100 reset the next-hop router to themselves. R2, R3, and R4 are route reflector clients of R1 and R5 is a non-client iBGP peer of R1. What is the BGP next hop on R5 for the address 10.1.1.0/24?
  1. R1
  2. R2
  3. R3
  4. R4
  5. R6
Correct answer: D
Question 2
Refer to the exhibit. Your junior design engineer presents this configuration design. What is the next-hop router for CE3, and why?
  1. CE1. BGP weight is higher than CE2.
  2. CE2. EBGP administrative distance is lower than RIP.
  3. CE2. The link between CE2 and PE1 has more bandwidth than CE1-to-PE1.
  4. CE1. HSRP on CE1 is in active state.
Correct answer: A
Question 3
A network design includes a long signaling delay in notifying the Layer 3 control plane that an interface has failed. Which two of these actions would reduce that delay? (Choose two.)
  1. Enable lower data link layer recovery systems to have an opportunity to restore the interface.
  2. Increase the notification of interface flaps.
  3. Reduce the time for the network to reconverge.
  4. Increase network stability.
Correct answer: AD
Question 4
When developing a multicast network design, SSM should be used for which type of source and receiver distribution?
Correct answer: To work with this question, an Exam Simulator is required.
Question 5
A service provider has a Resilient Ethernet Protocol ring running as a metro backbone between its locations in one city. A customer wants to connect one site with one box redundant to the Resilient Ethernet Protocol ring at two different service provider locations. How can this be done without producing any Layer 2 loops within the network design?
  1. Spanning tree at the service provider side only must be enabled.
  2. Spanning tree at the customer side only must be enabled.
  3. Flex Links at the service provider side only must be enabled.
  4. Flex Links at the customer side only must be enabled.
  5. EtherChannel at the service provider side and the customer side must be enabled.
  6. Spanning tree at the service provider side and the customer side must be enabled.
  7. Flex Links at the service provider side and the customer side must be enabled.
Correct answer: D
Question 6
A company plans to include Nonstop Forwarding and Bidirectional Forwarding Detection as a part of their network redundancy plan. In which two ways do NSF and BFD work together when different hardware platforms are compared? (Choose two.)
  1. During supervisor engine or routing engine failover, the NSF feature will always ensure that the BFD at the peer router will not trigger a link down independent of the used hardware platform.
  2. At some hardware platforms, BFD and NSF are not supported together. During supervisor engine or routing engine failover, the BFD at the peer router will trigger a link down.
  3. To ensure that BFD at the peer router will not trigger a link down during NSF, the BFD packets must be processed fast enough, and, during supervisor engine or routing engine failover, by processing the BFD independent from the supervisor engine or routing engine.
  4. Because BFD is always processed at the line cards (not at the supervisor engine or routing engine), a supervisor engine or routing engine failover will not affect the BFD peer router.
  5. Because BFD is always processed at the supervisor engine or routing engine, a supervisor engine or routing engine failover will always trigger a link down at the peer router.
Correct answer: BC
Question 7
Why is H-VPLS considered more scalable than flat VPLS?
  1. It minimizes signaling overhead by building two separate layers pseudowire meshes.
  2. It minimizes signaling overhead by only requiring a full pseudowire mesh among N-PEs.
  3. It eliminates signaling overhead on core devices.
  4. It eliminates signaling overhead between the N-PE and U-PE.
Correct answer: AB
Question 8
You are designing a network to support data, voice and video. Which two main factors will you address to improve network convergence? (Choose two.)
  1. event propagation delay
  2. failure detection delay
  3. forwarding engine update delay
  4. routing table recalculation delay
Correct answer: BD
Question 9
Refer to the exhibit. You are developing a migration plan to enable IPv6 in your IPv4 network.
Starting at R3 and assuming default IS-IS operations, what is likely to happen when you enable IPv6 routing on the link from R3 to R2?
  1. Only R3 and R2 have IPv4 and IPv6 reachability.
  2. R2 receives an IPv6 default route from R3.
  3. Loopback reachability between all routers for IPv4 is lost.
  4. All routers except R2 are reachable through IPv4.
  5. R3 advertises the link from R3-R2 to R1, R4 and R5 only.
Correct answer: C
Question 10
Your design plan includes mutual redistribution of two OSPF networks at multiple locations, with connectivity to all locations in both networks. How is this accomplished without creating routing loops?
  1. Use route maps on the ASBRs to allow only internal routes to be redistributed.
  2. Use route maps on the ASBRs to allow internal and external routes to be redistributed.
  3. Use route maps on the ASBRs to set tags for redistributed routes.
  4. Use route maps on the ASBRs to filter routes with tags so they are not redistributed.
Correct answer: D
Question 11
Service provider XYZ plans to provide dedicated Internet access and MPLS L3VPN services to business customers. XYZ has these design specifications:
  • MP-BGP running on the core MPLS P routers with external Internet routes.
  • The core network will include 16 Point of Presence IP POPs throughout the Asia-Pacific region.
  • An additional nine non-P routers will use EBGP peering with multiple providers for Internet traffic.
  • An additional 50 PE routers will provide end customers with dedicated Internet access and L3VPN services throughout the Asia-Pacific region.
In what two ways can the MP-BGP be removed from the MPLS P core routers and still provide dedicated Internet access and MPLS L3VPN services? (Choose two.)
  1. Disable BGP from the MPLS core P routers and have the MPLS core P routers run OSPF and LDP.
  2. Enable separate BGP control plane routers using a route reflector server concept that will be fully meshed with peer route reflector servers and have clients as MPLS PE routers and EBGP peering routers.
  3. Enable all EBGP routers as route reflector servers and MPLS PE routers as their clients.
  4. It is not possible to disable BGP from the MPLS core P routers without impacting the dedicated Internet access and MPLS L3VPN services.
