Q12. Your customer asks you to assist with their traffic policy design. They want to guarantee a minimum amount of bandwidth to certain traffic classes. Which technique would you advise them to implement? 

A. Modular QoS CLI 

B. committed accessrRate 

C. policy-based routing 

D. traffic shaping 

Answer: A 


Q13. 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 

Answer: B 


Q14. In a large enterprise network with multiple data centers and thousands of access devices, OSPF is becoming unstable due to link flapping. The current design has the access devices multihomed to large aggregation routers at each of the data centers. How would you redesign the network to improve stability? 

A. Add a layer of regional Layer 3 aggregation devices, but leave the ABR function on the data center aggregation routers. 

B. Add a layer of regional Layer 2 aggregation devices, but leave the ABR function on the data center aggregation routers. 

C. Add a layer of regional Layer 3 aggregation devices and move the ABR function to the regional aggregation device. 

D. Add a layer of regional Layer 2 aggregation devices and move the ABR function to the regional aggregation device. 

Answer: C 


Q15. You are designing an Out of Band Cisco Network Admission Control, Layer 3 Real-IP Gateway deployment for a customer. Which VLAN must be trunked back to the Clean Access Server from the access switch? 

A. untrusted VLAN 

B. user VLAN 

C. management VLAN 

D. authentication VLAN 

Answer: A 


Q16. Your enterprise customer has asked where they should deploy flow monitoring in their network to monitor traffic between branch offices. What is your design recommendation? 

A. at the edge of the network so that user traffic will be seen 

B. at the central site, because all traffic from the remotes will be seen there. 

C. in the core, because all traffic will be seen there 

D. in the data center, because all user traffic will be seen there 

Answer: B 


Q17. A planned EBGP network will use OSPF to reach the EBGP peer addresses. Which of these conditions should be avoided in the design that could otherwise cause the peers to flap continuously? 

A. An ACL blocks TCP port 179 in one direction. 

B. IP addresses used to peer are also being sent via EBGP. 

C. The OSPF area used for peering is nonbackbone (not area 0). 

D. The routers are peered by using a default route sent by OSPF. 

Answer: B 


Q18. You have been tasked with designing a data center interconnect as part of business continuity. You want to use FCoE over this DCI to support synchronous replication. Which two technologies allow for FCoE via lossless Ethernet or data center bridging? (Choose two.) 

A. EoMPLS 

B. DWDM 

C. Multichassis EtherChannel over Pseudowire 

D. OTV 

E. VPLS 

F. SONET/SDH 

Answer: BF 


Q19. 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. 

Answer: A 


Q20. Which option is a benefit of using N-Port Virtualization? 

A. reduces the amount of domain IDs that are used in the fabric 

B. does not need to create zoning 

C. reduces latency when using local switching on Fibre Channel ports 

D. allows trunking to the upstream switch 

E. does not need to configure the upstream switches 

Answer: A
