• Question 615:

  

  Refer to the exhibit. The Service Provider is deploying Internet service to its VRF customers by using vrf INTERNET. A dedicated firewall provides NAT functionally towards the Internet. Assume that IP address overlapping between VRFs is not an issue.

  Which three configuration steps are required to add Internet service to the VRF customers? (Choose three.)

  A. Export the RD of vrf INTERNET from all customer VRFs.
  B. Originate a default route on PE4 in vrf INTERNET.
  C. Import the RD from vrf INTERNET in all customer VRFs.
  D. Originate a default route on the firewall in vrf INTERNET.
  E. Import the VRF "INTERNET" Route Target in all customer VRFs.
  F. Import the Route Target of all customer VRFs in vrf INTERNET.
  G. Leak all VRF routes to the global routing table.
  B. Originate a default route on PE4 in vrf INTERNET.
  C. Import the RD from vrf INTERNET in all customer VRFs.
  G. Leak all VRF routes to the global routing table.

• Question 616:

  On Cisco IOS devices, which IS-IS feature reduces the convergence time for prefixes designated as high priority?

  A. iSPF
  B. Fast-Flooding
  C. Prefix prioritization
  D. Advertise passive only
  C. Prefix prioritization

• Question 617:

  Which two network management models are supported by IPoDWDM? (Choose two.)

  A. virtual transponder protocol management
  B. segmented management
  C. integrated management

• Question 618:

  A service provider offers four classes of service for MPLS VPN customer with the following IPP/EXP values:

  i. voice = 5

  ii. video = 4

  iii. priority data = 3

  iv.

  best-effort data = 0

  The service-provider also supports multicast VPN services in the priority data and best-effort classes. Multicast VPN is implemented as a draft-rosen profile. On a P router, in the MPLS core, the ingress QoS policy-map must classify all

  incoming packets, so that different classes of traffic can be property handled in fabric queues and egress queues. All types of packets in the core network must be covered.

  Which ingress classification offers the optimal performance and provides the minimum number of actions that match the service provider QoS requirements?

• Question 619:

  An ISP has hundreds of routers that run IS-IS on its network. The ISP is currently redesigning the network, to improve performance and convergence. Which two IS-IS features meet the ISP requirements when changes happen on the network? (Choose two.)
