Question 1

Which of the following statements about inter-AS VPN Option A are true? (ACE)

AMore logical links must be configured between ASBR-PEs when more VPNs are deployed.

BOption A provides excellent scalability and supports a great number of VPNs.

CThe VPN instances on an ASBR-PE can be bound to both physical interfaces and logical interfaces.

DASBR-PEs communicate with each other only through EBGP.

EASBR-PEs communicate with each other through any multi-instance (PE-CE) capable routing protocol.

Answer : A, C, E

Question 2

Which statements about the edge access layer is true?

AUsing the packet technology it provides a comprehensive transport platform that boasts high reliability, quality of service (QoS) assurance, and large capacity.

BIt implement call control. With the software technology as the core, it completes basic real-time call control and connection control.

CIt connections users to the network by providing various access means, and converts the format of information can be transmitted on the network.

DIt process additional value-added service and operation support for established callas.

Answer : B

Question 3

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

Answer : A

Question 4

Exhibit:

The figure shows the typically mode in which a common softswitch access the bearer network. VRRP is enabled on RTA and RTB. In normal cases, RTA is the VRRP master router and RTB is the VRRP is the VRRP salve router. The ETH_trunk is enabled between RTA RTB. IF VRRP is not bounded to BFD and each [parameter uses their default settings, which statement is the true when the upstream link of RTA is faulty?

ARTB cannot receive the heartbeat packet from RTA, and both routers become master routers.

BThe VRRP status remain unchanged but the downstream traffic is directly forwarded from RTB to the MSoftx.

CThe ARRP status remain unchanged but the downstream traffic is forwarded from RTB to the MSoft through RTA

DThe ARRP status immediately between RTA and RTB and RTB, and RTB becomes the master router.

Answer : C

signaling?

ACross circuit connection (CCC)

BMartini

CKompella

Answer : B

Question 6

Which statement describes the delay requirement of the voice service for the IP bearer network?

ABearer network delay=50 ms, allowed maximum delay = 100 ms

BBearer network delay=150 ms, allowed maximum delay = 200 ms

CBearer network delay=10s, allowed maximum delay = 20s

DNo strict requirement.

Answer : A

Question 7

Refer to the exhibit.

As shown in the figure, inter-AS VPN Option A is used. CE 1 and CE 2 belong to the same VPN.AS 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 CE 2 can ping CE 1. Which router allocates an inner label when PE 2 forwards packets from CE 2 to CE
