Q1. A service provider has a Resilient Ethernet Protocol ring running as a metro backbone between its locations in one city. A customer wants to connect one site with one box redundant to theResilient Ethernet Protocol ring at two different service provider locations. How can this be done without producing any Layer 2 loops within the network design? 

A. Spanning tree at the service provider side only must be enabled. 

B. Spanning tree at the customer side only must be enabled. 

C. Flex Links at the service provider side only must be enabled. 

D. Flex Links at the customer side only must be enabled. 

E. EtherChannel at the service provider side and the customer side must be enabled. 

F. Spanning tree at the service provider side and the customer side must be enabled. 

G. Flex Links at the service provider side and the customer side must be enabled.

Q2. 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.

Q3. Refer to the exhibit. 

The design is being proposed for use within the network. The CE devices are OSPF graceful restart-capable, and the core devices are OSPF graceful restart-aware. The WAN advertisements received from BGP are redistributed into OSPF. A forwarding supervisor failure event takes place on CE A. During this event, how will the routes learned from the WAN be seen on the core devices? 

A. via CE A and CE B 

B. via CE A 

C. via CE B 

D. no WAN routes will be accessible

Q5. You are designing a network that includes IP QoS. Which two architectures could be used to ensure that IP QoS is implemented properly? (Choose two.) 

A. Differentiated Services, where the user, with the assistance of the RSVP signaling protocol, reserves the resources end to end before sending the data 

B. Integrated Services, where the user, with the assistance of the RSVP signaling protocol, reserves the resources end to end before sending the data 

C. Integrated Services, which relies on the information carried within each packet to make resource-allocation decisions at each network node 

D. Differentiated Services, which relies on the information carried within each packet to make resource-allocation decisions at each network node 

E. Integrated Services, where the user, with the assistance of the DSCP signaling protocol, reserves the resources end to end before sending the data

Q6. A company wants to connect two data center sites using a hub-and-spoke design with 2000 remote sites. One design consideration is the requirement to transfer MPLS packets over the public Internet. In addition, one router at each site should be used, and the MPLS packets must be encapsulated inside IP packets because the public Internet cannot transfer native MPLS packets. Which feature can be used to simplify the network design? 

A. GET VPN can be used to encrypt the MPLS packets with IPsec. 

B. DMVPN can be used to build up GRE tunnels dynamically with MPLS encapsulation inside. 

C. L2TPv3 can be used to encapsulate the MPLS packets. 

D. Site-to-site IPsec without GRE can be used to encapsulate the MPLS packets. 

E. PPPoE can be used to encapsulate the MPLS packets.

Q7. A network design includes a long signaling delay in notifying the Layer 3 control plane that an interface has failed. Which two of these actions would reduce that delay? (Choose two.) 

A. Enable lower data link layer recovery systems to have an opportunity to restore the interface. 

B. Increase the notification of interface flaps. 

C. Reduce the time for the network to reconverge. 

D. Increase network stability.

Q8. You are creating a network design that will influence the traffic path across the MPLS core on a virtual private LAN. Which parameter is included in your design to manage the traffic? 

A. Deploy MPLS traffic engineering and modify the path using the preferred path. 

B. Deploy MPLS traffic engineering and modify the path using auto-route, static routing, or PBR. 

C. Create an MPLS traffic engineering tunnel and modify the path using a static route. 

D. Create an MPLS traffic engineering tunnel and modify the path using auto-route announce.
