Refer to the exhibit.

As shown in the topology, RTB directly connects to RTC through the POS
interface. To implement the TE function, RTB and RTC are configured as follows:

정답: D
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?

정답: B,C
As shown in the figure, for SWA, Eth0/2 belongs to VLAN 2, and Eth0/24 (PVID = 2) is a trunk interface and permits packets from VLAN 2 and VLAN 3 to pass through; for SWB, Eth0/2 belongs to VLAN 2, Eth0/3 belongs to VLAN 3, and Eth0/24 (PVID) is a trunk interface and permits packets from VLAN 2 and VLAN 3 to pass through. Which statement is true?

정답: C
On the IP bearer network, different VPN users (VPN A and VPN B) must access the internet through the same egress. Which of the following schemes can achieve security isolation VPNs and have the best scalability?

정답: B
As shown in the figure, the costs of paths from RTA to RT 11, RT 12, RT
13, RT 14, and RT 15 are all 10 and the available bandwidth is 200 Mbit/s.
The costs of paths from RTB to RT 31, RT 32, RT 33, RT 34, and RT 35 are all 10 and the available bandwidth is 200 Mbit/s.
The costs of paths from RT 11 to RT 21 and from RT 21 to RT 31 are both 5. The available bandwidth is 200 Mbit/s.
The cost of the path from RT 12 to RT 32 is 5 and the available bandwidth is 120 Mbit/s. The cost of the path from RT 13 to RT 33 is 10 and the available bandwidth is 80 Mbit/s.
The cost of the path from RT 14 to RT 34 is 10 and the available bandwidth is 100 Mbit/s.
The cost of the path from RT 15 to RT 35 is 10 and the available bandwidth is 100 Mbit/s.
The load balancing rule of Constraint Shortest Path First (CSPF) is set to Random on RTA.
Which path will a 100 Mbit/s tunnel from RTA to RTB take?

정답: B,E
Which statement about the Ethernet clock synchronization technology used in actual solutions is true?

정답: D
RTA is a leaf router that directly connects to host A through interface GigabitEthernet 1/0/0. The interface is configured as follows:
interface Ethernet1/0/0
undo shutdown
ip address 192.168.4.2 255.255.255.0
pim sm
igmp enable
igmp version 3
igmp ssm-mapping enable
Configurations in the IGMP view are as follows:
igmp
ssm-mapping 233.1.1.0 255.255.255.0 10.10.1.1
A user sends an IGMPv2 Report message on host A to join groups 232.1.1.1 and 233.1.1.1 but the user cannot receive (10.10.1.1, 232.1.1.1) and (10.10.1.1, 233.1.1.1) messages. To solve this problem, which of the following configurations are required?

정답: B,C
Refer to the exhibit.

As shown in the figure, RT 5 is a stub area router, an external Internet route is imported by RT 1, and a virtual connection is established between RT 1 and RT 3.At present, the Internet is accessible to routers except RT 5. Why can the Internet not be accessed from RT 5?(Select two answers)

정답: A,D
Which of the following statements about the MAC address learning in VPLS are true? (ACD)

정답: B,C,D
Which statement describes the delay variation requirement of the voice service for the IP bearer network?

정답: B
As shown in the figure, the PHP function is enabled on all routers by default and an MPLS TE tunnel RT 1-RT 2-RT 3-RT 4-RT 5 is set up between RT 1 and RT 5. See the figure for label distribution of the TE tunnel. A bypass tunnel RT 2-RT 6-RT 4 is configured on RT 2 to protect RT 3. See the figure for the label distribution of the bypass tunnel. When RT 3 is faulty, RT 2 switches traffic to the bypass tunnel. How many MPLS labels do packets on the path from RT
6 to RT 4 have? What is the value of each label?

정답: B
Exhibit:

As shown in the figure, inter-AS VPN Option A is used. CE 1 and CE 2 belong to the same VPNAS 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 VPNs configured on the PE and ASBR are both named vpn-1 and CE 2 can ping CE1. Which command can be ruin on ASBR 2 to find out route 10.1.1.1/24?

정답: B
