Question 1

Exhibit:

As shown in the figure, the AS number of operator 1 is 100 and that of

operator 2 is 200. Option C is used for exchanging VPN routes between AS 100 and AS 200. Which of the following statements about Option C are true?

AASBRs are required to exchange VPN-IPv4 routes.

BASBRs do not exchange VPN-IPv4 route.

CPEs in different ASs are connected using multi-hop EBGP for direct exchange of VPN-IPv4 routes.

DCompared with Option B, Option C greatly reduces the load of the ASBR; therefore, the ASBR will no longer be a bottleneck that hinders network development.

Answer : B, C, D

Question 2

Which of the following statements about IGP Shortcut and FA are true?

AAn MPLS TE tunnel is viewed as a link and the MPLS TE tunnel interface is used as the outbound interface of a route.

BWhen IGP Shortcut is enabled, MPLS TE tunnels can be advertised to routers as if they are links.

CIf FA is enabled on an MPLS TE tunnel, the MPLS TE tunnel can be shared by other routers.

DOSPF BFD does not need to be applied to IGP Shortcut-enabled tunnels.

Answer : A, C, D

Question 3

Which statement about the edge access layer is true?

AIt connects users to the network by providing various access means, and converts the format of
information so that the information can be transmitted on the network.

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

CIt implements call control. With the softswitch technology as the core, it completes basic realtime call control and connection control.

DIt provides additional value-added services and operation support for established calls

Answer : A

Question 4

BGP often uses AS PATH to control inter-area routes. Which of the following regular expressions helps ensure that routes within AS 100 and neighboring ASs are received from only one EBGP neighbor?

A100_([0-9]+)$

B^100_([0-9]+)$

C^100_([0-9]*)$

D^100_([0-9]*)

Answer : C

Question 5

Exhibit:

RTA is an edge route of the MPLS backbone network. It provides the access for users under layer 2 switches and differentiates user by subinterface. User access VALN 100 and has subscribed to the His ViIP , and services. According to 802 1p priorities, the value 0 indicates the HIS service, 1 indicates the VoIp service and 4 indicate the IPTV service. The DiffSerc model is deployed in E-LSP mode on the MPLS network,

And the STC is configured for subinterface on the access side of RTA (the qos phb disable command is not configured). Outgoing on the traffic on the G1/0/0.1 suninterface involves the His VoIP, and services on the access side of RT

AWhich statements about EXP about values corresponding to these three services is true?

AAt least three EXP values be contained, and the values are uncertain.

BOnly two EXP values be contains, and the values are certain.

CThe EXP values must be 0, 1, and 4.

DOnly one EXP may be contained, and the value is uncertain

Answer : A, A

Question 6

As shown in the figure, the bearer network is deployed in full mesh mode. For example, RTA uses the physical interface ATM 1/0/0. The interface is devised into ATM 10/0.2 connect to RTC and RTD, respectively . The GigabiteEthernet 2/0/0 and GigabitEthernet 3/0/0 interface are used to set up a trunk as the VRRP heartbeat cable. The UMG work in active/standby mode. Media interface connected to RTA and RTB belong to VLAN 10. VRRP is enable at the VLAN interface RTA is the master router. The interface is configured as follows:
