Q11. Refer to the exhibit. A customer is running IS-IS within a network and is using BGP as a CE-PE routing protocol. Which action allows CE1 to get the subnet 10.10.2.0/24 over the CE1-PE1 link, regardless of whether there is a flap in the MPLS link or backdoor link?
A. Configure the neighbor <PE1-IP>weight 33768 command on CE1 under the BGP process.
B. Configure the distance bgp 115 200 200 command on CE1 under the BGP process.
C. Configure the distance 30 ip command on CE1 under the IS-IS process.
D. Configure the distance bgp 115 200 200 command on CE2 under the BGP process.
E. Configure the neighbor <PE1-IP>weight 33768 command on CE2 under the BGP process.
Answer: B
Q12. DRAG DROP

Answer:
Q13. A service provider is implementing Ethernet solutions for clients that are not being provisioned within the MPLS core network. Which solution allows the Service Provider to complete Ethernet circuit provisioning in this scenario?
A. L2TPv3
B. VPLS
C. AToM
D. PPPoE
Answer: A
Explanation:
L2TPv3 defines the L2TP protocol for tunneling Layer 2 payloads over an IP core network using Layer 2 virtual private networks (VPNs). Benefits of this feature include the following:
. Simplifies deployment of VPNs.
. Does not require Multiprotocol Label Switching (MPLS) virtual private network (VPN).
. Supports Layer 2 tunneling over IP for any payload.
. Supports data encapsulation directly over IP (IP protocol number 115), not using User Datagram Protocol (UDP) .
Supports point-to-point sessions, not point-to-multipoint or multipoint-to-point sessions .
Supports sessions between the same Layer 2 protocols, for example Frame Relay-to-Frame Relay or ATM-to-ATM.
Q14. Refer to the exhibit.
Customer ABC is peering with two service providers for Internet Access In order to prevent the AS100 from becoming a transit AS between ISP_1 and ISP_2 Which BGP configuration must be applied to achieve this goal?

Answer: C
Q15. A service provider is designing control policies at the customer edge of the network, in order to prevent usage that exceeds the contracted terms A new client that is contracted for only 2 Gbps is connecting to the service provider edge with a 10 Gbps interface. Which two OoS strategies meet the design goal? (Choose two.)
A. On the customer edge device, enable policing on the interface that is connected to the service provider.
B. On the service provider edge, enable WRED on the customer port.
C. On the customer edge, enable WRED on the interface that is connected to the service provider
D. I On the service provider edge, enable policing on the customer port
E. the customer edge device, enable traffic shaping on the interface that is connected to the service provider.
F. C On the service provider edge, enable traffic shaping on the customer port
Answer: D,E
Q16. Refer to the exhibit.
OSPF is already running with the default OSPF parameters. R1 has added a new subnet (loopback 11). What will occur in regards to SPT computing on R2 router?
A. Adding ispf command on R2 router, the entire SPT will be computed on R2 router.
B. Because 10.11.11.11/32 prefix information will be in a LSA type 3 on R2 router's OSPF database, R2 router will run partial SPF computation.
C. Adding ispf command on R2 router, R2 router will recompute only the affected part of tree.
D. Because 10.11.11.11/32 prefix will be a LSA type 1 on R2 router's OSPF database. R2 router will always run a full SPF computation, even though an OSPF optimization is applied on R2 router.
Answer: C
Q17. Refer to the exhibit.
In the topology, networks in VRF A use the service provider network for transport. PE1 and PE2 run MP-BGP VPNv4 peering. Links between PE and P routers have MPLS enabled. Links between R1 and P routers do not support MPLS.
Which technology can be implemented to build MPLS services between P1 and P2?
A. Layer 3 VPN over GRE Tunnels
B. L2TPv3
C. RSVP Signaled Tunneling
D. MPLS LDP Tunnels
E. MPLS TE
Answer: B
Q18. Refer to the exhibit. Router RT1 has three equal-cost paths back to the source. Which configuration should be applied in order to load-balance the multicast traffic across all three links.
A. Create three static multicast routes where each pointing out to one or three interfaces.
B. Enable PIM multipath.
C. Create a tunnel interface between RT1 and RT2. Enable PIM on the interface tunnel and disable PIM on the three interfaces part of equal-cost path between RT1 and RT2.
D. PIM load balance is not possible. PIM only chooses one interface for RFC check and prunes the other interfaces.

Answer: B,C
Q20. Refer to the exhibit.
A CE connected to a service provider has an agreement to use 512Mbps of bandwidth. Which QoS configuration must be modified to ensure that the traffic matches the agreed bandwidth?
A. Apply the same CE QoS configuration on PE on inbound direction.
B. Change the outbound direction of the service-policy to inbound for ingress traffic shaping.
C. Treat the class-default as best-effort by removing the shape average 512000 command
D. Replace the shape keyword with police keyword in both classes
E. Reconfigure the policy-map as a nested policy with the shaping applied as a parent for all child policies
Answer: E
