You are designing a fabricpath network that connects to a spine-and-leaf topology using Layer 2 IS-IS as the IGP. The solution must be able to detect changes in the network topology and calculate loop-free paths to other nodes in the network that are being used as top-of -rack switches, which three characteristics of this fabricpath design solution are true? (Choose three)

• A.The FabricPath domain must be replaced because it because it does not run STP.
  Varation
• B.To use the basic FabricPath functionality, you must configure IS-IS on every interface between the leaf-and-spine switches
• C.Each switch computes its shortest path to every other switch in the network using the SPF algorithm.
• D.FabricPath Layer 2 IS-IS uses the standard IS-IS functionality to populate up to 16 for a given destination switch.
• E.The switch operating system uses multiple equal-cost parallel links that provide ECMP.
• F.The interfaces in FabricPath network run only the FabricPath Layer 2 IS-IS protocol with FTags disabled.

A multicast network is using bidirectional PIM. Which two actions, when combined, can achieve high availability so that two RPs within the same network can act in a redundant manner? (Choose two.)

• A.Manipulate the multicast routing table by creating static mroutes to the two RPs.
• B.Advertise routes for the two RPs with the same subnet mask through the unicast routing protocol.
• C.Use a phantom RP address.
• D.Manipulate the administrative distance of the unicast routes to the two RPs.
• E.Use Anycast RP based on MSDP peering between the two RPs.
• F.Advertise routes for the two RPs with different subnet mask lengths through the unicast routing protocol.

A customer is using a service provider to provide a WAN backbone for a 30-site network. In establishing the network, the customer must work within these constraints:
The customer has a self-managed MPLS backbone.
The VPLS WAN backbone of the service provider does not support PIM snooping.
Multicast VPN must be used for multicast support inside some VRFs.
What can the customer do so that multicast traffic is NOT flooded to all sites?

• A.Configure static GRE tunnels and run the MPLS and multicast VPN inside these GRE tunnels.
• B.Use Label Switched Multicast for the multicast transport.
• C.Use PIM-SSM as the multicast routing protocol with IETF Rosen Draft multicast VPN.
• D.Configure a static mapping between multicast addresses and MAC addresses.
• E.Use GET VPN to encrypt the multicast packets inside the WAN.

A service provider must provide Internet connectivity to an MPLS Layer 3 VPN customer.
Which solution allows this customer to have Internet access?

• A.Implement policy-based routing between PE and CE
• B.Implement a global default route with a next hop in the VRF late on PE
• C.Implement a default route in the VRF with a next hop in the global routing table of PE
• D.Implement destination NAT between the VRF and the global RIB of PE

Refer to the exhibit.

You are planning the design of an encrypted WAN. IP packets will be transferred over
encrypted GRE tunnels between routers B and C.
The packet size is limited to a maximum of 1500 bytes inside the WAN between routers B and C.
If endpoint 1 tries to send 1500byte IP packets to endpoint 2, in what three ways will the network design handle the fragmentation in three different possible network configurations? (Choose three.)

• A.When router B fragments packets before the encryption, router C must reassemble these fragmented packets.
• B.When router A fragments packets, endpoint 2 must reassemble these fragmented packets.
• C.When router A fragments packets, router C must reassemble these fragmented packets.
• D.When router B fragments packets after the encryption, the endpoint 2 must reassemble these fragmented packets.
• E.When router B fragments packets before the encryption, endpoint 2 must reassemble these fragmented packets.
• F.When router B fragments packets after the encryption, router C must reassemble these fragmented packets.
