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

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?

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:

Two records are generated for the same NBR ID, as shown in bold fonts. Which statement is true?

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?

On a BGP/MPLS VPN, a PE and a CE communicate with each other over OSPF. Which command cannot be configured on the PE?

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?
