Refer to the exhibit.

As shown in the figure, RTA belongs to AS 100 and has an EBGP
neighbor relationship with RTB. RTB, RTC, RTD, RTE, and RTF belong to AS 200.RTB, RTD, and RTE are assigned to AS65001, RTC to AS65002, and RTF to AS65003.
1. When route 1.1.1.1/32 is imported from RTA, what is the AS_Path attribute of this route to be advertised to RTF?
2. When route 1.1.1.1/32 is imported from RTC, what is the AS_Path attribute of this route to be advertised to RTA?
3. When route 1.1.1.1/32 is imported from RTC, what is the AS_Path attribute of this route to be advertised to RTE?
The attributes are as follows:

• A.(65001) 200 100; (65002) (65001) 200; (65002)
• B.(65003) (65001) 200 100; 200; 200
• C.100; 200; empty
• D.(65001) 100; 200; (65002)

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

In MPLS QoS, traffic policies are developed based on simple traffic classification and complex traffic classification. In traffic policies based on simple traffic classification, the service class, color, and drop priority of packets are reset based on the tags in packets. In traffic policies based on complex traffic classification, measures such as traffic policing, priority re-marking, packet filtering, policybased routing, and traffic sampling are implemented based on the traffic type. Generally, simple traffic classification is applied on border routers in DiffServ domains, and complex traffic classification core routers. QoS traffic policies are configured by performing the following operations:
1. Defines DiffServ domains and configuring a traffic policy.
2. Classifies traffic.
3. Defines traffic behaviors and configures characteristics of behaviors.
4. Defines a traffic policy and specifies actions for traffic categories.
5. Applies the traffic policy.
6. Configures L-LSP.
7. Configures reverse address check.
8. Adds interfaces to the DiffServ domains.
Which of the preceding operations are required when you configure simple traffic classification?

• A.1 6 8
• B.1 5 6
• C.2 4 5 7
• D.2 3 4 8

Which of the following statements about the MAC address learning in VPLS are true? (ACD)

• A.The PE learns the MAC address of a directly connected CE through the attachment circuit (AC) and learns the MAC address of a remote CE through the pseudo wire (PW).
• B.The PE learns the MAC address of a directly connected CE through the PW and learns the MAC address of a remote CE through the AC.
• C.In qualified mode, the PE learns MAC addresses on a per-VLAN basis in each virtual switch instance (VSI). Each user VLAN has its own broadcast domain and independent MAC address space.
• D.In unqualified mode, the PE learns MAC addresses on a per-VSI basis and all user VLANs share a broadcast domain and a MAC address space.
