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.

There are two hub-and-spoke networks in the following exhibit. Each has about 60 branches spread over a wide area. Connect routers P4S-RE and P4S-RF to two different frame providers. Problems with one provider have impacted branches connected to the other provider and reaching the data center.
Which is the best place to build flooding domain boundaries to isolate these WAN issues?

• A.at routers P4S-RB and P4S-RC, because this will provide a good balance between separating the complex topologies behind routers P4S-RD, P4S-RE, and P4S-RF from the core and good route aggregation
• B.at routers P4S-RB and P4S-RF, because this will provide good route aggregation and prevent routing along suboptimal paths in the case of link failure
• C.at router P4S-RA, because this will provide optimal route aggregation and prevent suboptimal routing in the case of link failure
• D.at routers P4S-RD, P4S-RE, and P4S-RF, because this will provide good route aggregation and also separate complex topologies within the network from one another

You have been hired to redesign a network due to issues with congestion. How will a router function if the QoS mechanism of congestion avoidance is integrated into the existing network design?
34

• A.the router handles the overflow of traffic by using FIFO
• B.the router handles the possible buildup of congestion by using WRED
• C.the router forces inbound and outbound traffic to stay within a defined profile by using rate limiting
• D.the router separates packets based on certain characteristics by using NBAR
• E.the router marks packets based on certain characteristics by using PBR

A network administrator is having problems with redistribution routing loops between two EIGRP processes. You've looked at the configurations and determined there is no filtering configured on the routes being redistributed. To avoid having a single point of failure, there are three routers configured to redistribute between the two routing protocols. Which solution would you recommend to minimize management complexity?

• A.use tags to control redistribution between the two processes
• B.reduce the number of routers redistributing between the two routing processes
• C.build and apply a route filter based on the networks being redistributed between the two processes
• D.replace one of the EIGRP processes with an alternate IGP

You are the SAN designer for the ABC Company. Due to budget constraints, there is increased pressure by management to further optimize server utilization by implementing virtualization technologies on all servers and increase virtual machines density. Faced with some SAN challenges, the server team requests your help in the design and implementation of the SAN in the new virtualized environment.
In which two ways can NPIV be used in your proposed design? (Choose two.)

• A.NPIV is used to assign multiple FCIDs to a single N Port.
• B.NPIV can be used to allow multiple applications on the same port to use different IDs in the same VSAN.
• C.You recommend NPIV so that hosts can be members of different zones.
• D.NPIV is used to define and bind multiple virtual WWNs (VIs) to a single physical pWWN.
