The traffic classification behavior is configured to the single rate dual-bucket CAR in color-blind mode at the upstream interface of the router. Configurations are as follows:
[Quidway]display traffic policy user-defined test User Defined Traffic Policy Information:
Policy: test
Statistic Enable
Classifier: default-class
Behavior: be
-noneClassifier: test
Behavior: test
Committed Access Rate:
CIR 400 (Kbit/s), PIR 0 (Kbit/s), CBS 100000 (byte), PBS 200000 (byte)
Conform Action: pass
Yellow Action: pass
Exceed Action: discardIf the traffic on an interface matches the traffic policy, the traffic rate is 10,000 PPS and the packet frame length (including the CRC) is 125 bytes, which is the closest number of packets transmitted through the interface in the first one second?

• A.2000
• B.2800
• C.1200
• D.400

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 need to be met.VPNA-CE 1 can interwork with VPNA-CE 2. 2>VPNB-CE 1 can interwork with VPNB-CE 2.
The figure shows the types of links between CEs and PEs and the VC IDs used in Martini mode.
Which of the following VC ID configurations are correct?

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

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?

• A.Configure ssm-policy in the PIM view and use the ACL to set the SSM group address range to 232.1.1.1.
• B.Configure ssm-policy in the PIM view and use the ACL to set the SSM group address range to 233.1.1.1.
• C.Configure ssm-policy in the PIM view and use the ACL to set the SSM group address range to 232.1.1.1 and 233.1.1.1.
• D.Configure ssm-mapping 232.1.1.0 255.255.255.0 10.10.1.1 in the IGMP view.

When the RSVP LSP FRR protection is enables, which of the following statements about the original RSVP LSP are true?

• A.The PATH message is sent by the PLR to the MP through a bypass LSP after modified.
• B.The MP sends the ResvTear message to the upstream node of the original RSVP LSP.
• C.The point of local repair (PLR) and the merge point (MP) can perceive the application of FRR but other nodes on the original RSVP LSP
• D.The RESV message is sent by the MP to an upstream node through a bypass LSP after modified.

On the typical access network of a bearer network, a core network device connects to two upstream CEs. CEs connect to PEs in a square shape. This access network must bear voice and signaling services. A CE must be configured with two VPNs to separate the voice and signaling services and ensure high security and QoS. The signaling service works in active/standby mode, and the voice service works in load sharing mode. The VRRP must be enabled between the CEs to terminate the signaling flow. If the network robustness is ensured and the network architecture is rational, which of the following statements about the topological structure are true?

• A.Instead of POS links, GE links are recommended between CEs and PEs.
• B.The total link bandwidth between CEs cannot be less than that between CEs and PEs.
• C.GE and FE links need to be used as the Eth-trunk between CEs to improve reliability.
• D.The voice service must be carried by GE links and the signaling service must be carried by FE links.
