Q6. Company X will be integrating an IPv6 application into their network and wants to develop a test environment to evaluate application performance across the network. This application will require both unicast and multicast communications. The company can do this implementation only in certain areas of its existing IPv4-only network, but wants all areas to communicate with each other. When developing the design to provide connectivity between these testing locations, what tunneling technology would work in this scenario? 

A. ISATAP 

B. 6to4 

C. DMVPN 

D. 6vPE 

E. 6PE

Q7. Which technique can you use to detect forwarding path failures at a uniform rate, and reconvergence times will be consistent and predictable when your routers are in the same broadcast domain? 

A. Enable BFD on your routers. 

B. Configure your routers with IP-SLA to ping the peer router. 

C. Configure your routers with IP-SLA and track to ping the peer and switch to a default route if the pings fail. 

D. Tune your routing protocol timers.

Q8. Company A has grown nationwide in the U.S., and each new remote branch has a Metro Ethernet circuit provisioned back to the data center at the headquarters on the West Coast. The operations team says that it cannot manage hundreds of circuits as the company continues to grow. You review the topology and notice that many of the branches are close to each other in geographical zones. How can you redesign this network to improve manageability and increase scalability? 

A. Add an aggregation layer router in each geographical zone. 

B. Add a redundant data center on the East Coast to serve some of the traffic there. 

C. Add a default route in each branch toward the data center on the West Coast. 

D. Use Optimized Edge Routing at the data center. 

E. Build an overlay MPLS network with Layer 3 VPN.

Q9. When you design a network, when would it be required to leak routes into a Level 1 area? 

A. when a multicast RP is configured in the nonbackbone area 

B. when MPLS L3VPN PE devices are configured in the Level 1 areas 

C. when equal cost load balancing is required between the backbone and nonbackbone areas 

D. when unequal cost load balancing is required between the backbone and nonbackbone areas
