Which statement is true?

7. 1- On the backbone network, if a PE is connect to a CE, VPN instances need to b reconfigured on the PE, and interface on the PE for connecting to the CE must be bound to a VPN instance. After binding an interface to a VPN instance, you must configure the IP address of the interface between PEs, IS-IS configured for PE interworking. PLSA basic capabilities and MPLS LSP are configured for LSP establishment, and MP _IBGP is configured for VPN route exchange VPN routes exchange , LDAP is short for Label Distribution Protocol, and IBGP is short for interior Border gateway protocol.

Configuration principles are as follows:

On the backbone network VPNs are not connected to a CE, VPN instance need to be configured on the PE, and an interface on the PE for connecting to the CE must be bounded to a VPN instance. After binding an interface to a VPN instance, you must configure the IP address of the interface Between

As shown in the figure, Super VLAN is enabled on SWA (a LAN switch).

The Super VLAN configuration is as follows:

Which of the following specifics the time order in which the preceding debugging information is generated?

13. Configure VRFs and relevant policies on a PE as follows:

If a route is imported to the routing table of VRF 1, which VRF can the route match?

14. Which statement about the configuration of route target (RT) and route distinguisher (RD) is true?

15. Which statement about the Hub s MPLS VPN networking is false?

16. Exhibit:

Which statement about inter-AS MPLS VPN Option_B is false?

17. Exhibit:

As shown in the figure, inter-AS VPN Option A is used. CE 1 and CE 2 belong to the same VPNAS 100 and AS 200 run IGP and LDP, respectively.

ASBRs communicate with each other through EBGP. the loopback interface address of CE 1 is 10.1.1.1/24 Suppose VPNs configured on the PE and ASBR are both named vpn-1 and CE 2 can ping CE1 .

Which command can be ruin on ASBR 2 to find out route 10.1.1.1/24?

18. Which of the following statements about the merits of the HoVPN networking are true?

19. Exhibit:

As shown in the figure, OSPF process 100 runs on both PEs and CEs, and VPN routers are transmitted between PE 1 and PE 2 through PGB CE 1 enables interface address 43.1.1.0/24 in area 0.A route to 43.1.10/24 .

How ever, does not exist in the routing table of CE 2 .

What are the possible causes?

20. As shown in the figure, a CE requires access to the internet, and PE 1is connected to the gateway.

Configurations on PE 1 are as follows:

PE 1 is connected to the internet gateway through interface 175.311.2 CE and CE 2 cannot ping the interface .

Which of the following statements are true?

21. Which statement about primary VPN tunnel binding is false?

22. As shown in the figure, CE and CE 2 belong to VPN A, CE 3 and CE 4 belong to VPN B, VPN A and VPN B share the public network tunnels between border PE 1 and PE 2, and LDP tunnels are configured between PE 1 and PE 2. To isolate resources for VPN service data from PE 2 to PE 1, a unidirectional TE tunnel is configured t forward data from PE1. The QoS policy propagation though the border gateway protocol (QPPB) feature is configured on PE 2, and a QoS policy is defined when VPNs are bound to tunnel interfaces.

Which of the following statements about the configurations on PE 2 are true?

23. Which of the following statements about control words in the L2VPN are true?

24. Which of the following statements about the VPLS packet forwarding are true?

26. On a VPLS network a PE router receive a packet that containers layer 2 user data from a PE .

How does the PE router determine the source VSI of this packet?

27. When the RSVP LSP FRR protection is enables, which of the following statements about the original RSVP LSP are true?

30. In MPLS QoS , traffic policies are developed on simple traffic classified and complex traffic classification policies based on simple traffic classification the service class color, and drop priority of packet are reset based on the packet in the traffic policies on complex traffic classification measures such as traffic classification is applied on border routers in Different domain, and traffic classification core routers.

QoS policies are configured by performing the following operations:

Defines DiffSer domain and configuring a traffic policy.

Classification traffic

Defines traffic behavior and configures characteristics of behaviors.

Defines a traffic policy and specifies for traffic categories

Applies the traffic policy

Configure L-LSP

Configures reserve address checks
