Question 1

On a BGP/MPLS VPN, a PE and a CE communicate with each other over OSPF. Which command cannot be configured on the PE?

Aroute-tag 3

Bdomain-id 3

Cvpn-instance-capability simple

Dsham-hello

Answer : C

Question 2

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?

ANAT translation must be configured on interface pos2/1.0 instead of interface s0./01.0

BA private network route must be configured on the internet gateway.

CThe public parameter of a static default route must be configured.

DA default must be configured on CE an CE 2.

Answer : B

Which of the following statements are false?

AIf the PIM-DM is enabled at Ethernet 6/2/0 on a router, the PIM-SM cannot be enabled at other interfaces on the router.

BEthernet 6/2/0 sends a PIM hello message every 100 seconds.

CThe TTL value is 60 in state-refresh messages sent by the router.

DEthernet 6/2/0 sends a state-refresh message every 10 seconds.

Answer : B, D

Question 4

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

Adds interface to the DiffSer domain

Which of the proceeding operations are required when you configured simple traffic classification?

A1 6 8

B2 3 4 8

C1 5 6

D2 4 5 7

Answer : B

Question 5

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?

Avrf4

Bvrf3

Cvrf2

Answer : C

Question 6

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

AIf routes need to exchange between two VPNs, the value of import RT of one VPN must be partially the same as Export RT of the other VPN.

BRD and RT of a VPN instance cannot be the same as those of another VPN instance on the same PE.

CIf routers need to exchanged two VPNs, the value of import RT of one of the same as that of RT of the other VPN.

DTwo instances of a VPN share an RT.

Answer : A

Question 7

As shown in the figure, RTA, RTB, and RTC use the OSPF protocol. The default cost value is used for links, and unicast routes converge on the entire network. The Loopback 0 interface is set to configure RTC as the RP or BSR. The SPT switching threshold uses the default value on RTB. The receiver joins the multicast group 225.1.1.1. The multicast source sends multicast data to the destination address 225.1.1.1. Which interface is the inbound interface in the (10.1.1.1, 225.1.1.1) entry on RTB?

AEthernet 1/0/0

BEthernet 1/0/1

CEthernet 2/0/0
