Q151. A Mobile Service Provider would like to design and deploy an Ethernet service which has similar physical link failover/failback characteristics on the active/backup links as the APS/MSP SONET properties. Which Layer 2 services should be considered to address this design feature? 

A. Port-Channel 

B. MLPPP 

C. Flex Link 

D. Ethernet Pseudowires 

Answer: C 

Q152. You are designing a multisite VPN solution for a customer and you are concerned with the additional overhead of point-to-point tunnels and the associated overlay routing with DMVPN. How does a GDOI-based VPN eliminate the additional tunnel and routing overhead found in DMVPN? 

A. The GDOI-based VPN requires overlaying a secondary routing infrastructure through the tunnels. 

B. In a GDOI-based VPN, all group members share a common security association. 

C. The GDOI-based VPN requires the provisioning of a complex connectivity mesh. 

D. The GDOI-based VPN leverages the routing protocol to find its peer for tunnel setup. 

Answer: B 

Q153. Refer to the exhibit.

A. PVRST 

B. REP 

C. MST 

D. G.8031 

E. BFD 

Answer: B

B. allows up to 32 optical carriers to be multiplexed onto a single fiber 

C. shares the same transmission window as DWDM 

D. uses the 850-nm band 

E. Passive CWDM devices require no electrical power. 

Answer: CE

Q156. The network administrator of a branch office network has decided to deploy Unicast RPF at the access layer. He insists that the design must guarantee that all the packets arriving on the router interfaces are assigned to the same interface subnet. 

Which mode of Unicast RPF would you recommend as the lead network designer? 

A. uRPF strict mode 

B. uRPF loose mode 

C. uRPF VRF mode 

D. RPF feasible mode 

Answer: A 

Q157. An IBGP mesh design is being scoped, and in the discussions, one of the design engineers proposes the use of route reflectors. Which limitation is valid when using route reflectors in this design? 

A. The configuration complexity on the routers will be increased. 

B. Route reflectors will limit the total number of routes in the topology. 

C. Multipath information is difficult to propagate in a route reflector topology. 

D. Route reflectors will cause an opportunity to create routing loops. 

Answer: C 

Q158. 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 

Q159. Refer to the exhibit. 

Acme Corporation hired you as a network designer to upgrade their network so that it supports IPv4 and IPv6 multicast. Which two protocols are needed on the LAN switch? (Choose two.) 

A. PIM sparse mode 

B. IGMP snooping 

C. PIM snooping 

D. Source Specific Multicast 

E. MLD snooping 

Answer: BE 

Q160. Refer to the exhibit. 

When designing an MPLS-based LAN extension between DC-1 and DC-2, what are three advantages of deploying VSS? (Choose three.) 

A. Layers 2, 3, and 4 flow-based load balancing 

B. native VSS and MEC failover without using scripts 

C. sub-second failover 

D. required to configure VPLS 

E. failover time depends on Cisco IOS EEM and STP convergence
