Question 21

Refer to the exhibit.

As shown in the figure, VPN routes are transmitted between PE 1 and
PE 2 through BGP. OSPF process 100 runs on both PEs and CEs. The following BGP route exists on PE 2.
[PE 2]display bgp vpnv4 vpn-instance red routing-table 43.1.1.0
BGP local router ID: 194.1.1.1
Local AS number: 100

A.The domain ID in the BGP route is the same as that configured on PE 2 and the route type is specified by a Type 1 LSA. Therefore, PE 2 needs to generate a Type 5 LSA and send it to CE 2.

B.The domain ID in the BGP route is the same as that configured on PE 2 and the route type is specified by a Type 1 LSA. Therefore, PE 2 needs to generate a Type 3 LSA and send it to CE 2.

C.The domain ID in the BGP route is different from that configured on PE 2 and the route type is specified by a Type 1 LSA. Therefore, PE 2 needs to generate a Type 5 LSA and send it to CE 2.

D.The domain ID in the BGP route is the same as that configured on PE 2 and the route type is specified by a Type 1 LSA. Therefore, PE 2 needs to generate a Type 1 LSA and send it to CE 2.

Question 22

Which of the following is the maximum length of the Ethernet frame encapsulated by QinQ?

A.1530

B.1522

C.1518

D.1526

Question 23

Exhibit.

As shown in the figure, one enterprise has VPN A, the other has VPN B, and the two VPNs each have two
CEs. The following requirements needs to be met.
VPNA-CA 1 can interwork with VPNA-CE 2
2>VPNA-CE 1 can interwork with VPNA-CE 2.
The figure shows the types of links between CEs and PEs and the IDs used in Martini mode. Which the
following VC ID configurations are correct?

A.VCID1 =1, VCID2 = 2, VCID3 =1, VCID4 +2

B.VCID1 =1, VCID2 = 2, VCID3 =3, VCID4 +4

C.VCID1 =2, VCID2 = 2, VCID3 =2, VCID4 +2

D.VCID1 =1, VCID2 = 1, VCID3 =2, VCID4 +2

Question 24

On a metropolitan area network, VIP customers access the network through the MPLS VPN to ensure their security. Which of the following security deployments are required for PEs?

A.Configure the ACL to filter out IP packets that use the IP address of the CE-connected interface as the destination address.

B.Deploy protocol authentication if a router protocol is used between PEs and CEs.

C.Configure the CP-CAR on the interface connected to the CE.

D.Configure the ACL to filter out data packets with common network viruses at the interface connected to the CE.

Question 25

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:
