Cisco 400-201 Online Questions & Answers

• Question 451:

  DRAG DROP

  Refer to the exhibit. ISP X must enable QoS propagation for prefix A via BGP from Site 1 to Site 2. Drag and drop the steps from the left into the correct order on the right. Not all options are used.

  

  Select and Place:

  

  

• Question 452:

  A router is unable to route packets over a PPPoE link. What could be the cause of this issue?

  A. incorrect IPCP connection for the agreed-upon IP address
  B. incorrect dialer map profile
  C. incorrect username of the PPP connection
  D. incorrect access list
  B. incorrect dialer map profile

• Question 453:

  

  Refer to the exhibit. IPTV video clients are connected to R6. Unicast and multicast traffic flows from R1 to R6. The OSPF cost of the R1-R2-R3-R6 path is lower than the R1-R5-R4- R3-R6 path.

  To enable load sharing and fast reroute, the design team decided to implement MPLS TE tunnels between R1 and R3 using the forwarding adjacency feature. After the MPLS TE tunnels are deployed, the multicast traffic stops working.

  While trouble shooting the issue, the operations engineer noticed that the OSPF route to the multicast source is learned via the MPLS TE tunnel, which causes the RPF check to fail. Which two solutions can prevent the multicast traffic from

  being affected by the RPF check failure due to the MPLS TE tunnel deployment? (Choose two)

  A. Replace forwarding adjacency by autoroute announce and enable the multicast-intact feature
  B. Enable PIM on the MPLS TE tunnel on both headend routers
  C. Enable the Multitopology routing feature
  D. Enable a new routing protocol, such as another OSPF process, on the core-facing links
  E. create a static mroute on R3 with the RPF pointing to the MPLS TE tunnel
  C. Enable the Multitopology routing feature
  E. create a static mroute on R3 with the RPF pointing to the MPLS TE tunnel

• Question 454:

  Refer to the exhibit. Which two actions must be applied to provide a seamless MPLS solution that integrates aggregation and core areas of the network by providing scalable end-to-end LSPs? (Choose two.)

  

  A. Replace Layer 3 VPN services with Layer 2 VPN services.
  B. Deploy BGP between PEs and ABRs with RFC 3107.
  C. Extend the IS-IS domain used in the core to the aggregation areas of the network.
  D. Set the next hop for the prefixes advertised by the ABR
  E. Enable VRF lite between core and aggregation links.
  B. Deploy BGP between PEs and ABRs with RFC 3107.
  D. Set the next hop for the prefixes advertised by the ABR

• Question 455:

  Which BGP feature protects the external BGP peering session from CPU utilization-based attacks that use forged IP packets?

  A. BGP multihop
  B. TTL security check
  C. BGP FlowSpec
  D. Secure BGP
  B. TTL security check

• Question 456:

  In MPLS-enabled networks, which two improvements does EVPN provide compared to traditional VPLS solutions? (Choose two)

  A. use of BGP as a control-plane protocol
  B. use of LDP to allocate EVPN-related labels
  C. optimized learning and flooding process
  D. leveraging of enhanced VFIs to provide greater scalability
  E. per-flow load balancing
  F. no need for exchange of MAC reachability between PEs
  C. optimized learning and flooding process
  E. per-flow load balancing

• Question 457:

  Which three statements about the Route Distinguisher (RD) are true? (Choose three.)

  A. The RD is a BGP extended community.
  B. The RD prefix and a route target make the VPNv4 address unique.
  C. RD, similar to the AS number, is assigned to a service provider by the Internet Assigned Numbers Authority (IANA).
  D. The RD is an 8-byte field.
  E. One customer may use different RDs for the same IPv4 route.
  B. The RD prefix and a route target make the VPNv4 address unique.
  D. The RD is an 8-byte field.
  E. One customer may use different RDs for the same IPv4 route.

• Question 458:

  Refer to the exhibit. Which Cisco IOS command is used to implement a VRF-aware GRE tunnel inside the MPLS network VRF Blue?

  

  A. tunnel destination vrf GREEN
  B. tunnel vrf GREEN
  C. ip vrf forwarding BLUE
  D. tunnel vrf BLUE
  E. tunnel destination vrf BLUE
  F. ip vrf forwarding BLUE
  D. tunnel vrf BLUE

• Question 459:

  Which statement about OSPFv3 and OSPFv2 is true?

  A. OSPFv3 supports multiple instances. and OSPFv2 does not.
  B. OSPFv3 and OSPFv2 by default include all address prefixes on an interface.
  C. OSPFv2 supports only IPv4 prefix advertisement, and OSPFv3 supports only IPv6 prefix advertisement.
  D. OSPFv3 does not support NBMA interfaces, and OSPFv2 does.
  A. OSPFv3 supports multiple instances. and OSPFv2 does not.

• Question 460:

  Which option describes a benefit of IPv6 VPN Provider Edge?

  A. Uses separate signaling plane, which provides more security than IPv4
  B. No requirement for a separate signaling plane
  C. Provides support for intra-AS and CSC scenarios
  D. BGP is the preferred routing protocol for connecting two SPs.
