User A want to obtain a better network service for business development and signs an SLA with a corner. User A purchases a bandwidth of 5 Mbit/s to ensure the voice service (requiring short delay), vide service, key data services, and other services, If you were corner network administrator.

The Huawei router is the hop RD where the SSM mapping function is enabled at the interface. Some IGMPv2 hosts expect to receive (1.0.01,232.1.0.1) (1.0.0.1232.1.0.2), and (2.0.0,232.1.3.2) dat a. How can you satisfy the preceding requirement with the least configurations?

Which of the following will cause an MPLS L2VPN VC to be Down?

In MPLS QoS , traffic policies are developed on simple traffic classified and complex traffic classification policies based on simple traffic classification the service class color, and drop priority of packet are reset based on the packet in the traffic policies on complex traffic classification measures such as traffic classification is applied on border routers in Different domain, and traffic classification core routers. QoS policies are configured by performing the following operations:
Defines DiffSer domain and configuring a traffic policy.
Classification traffic
Defines traffic behavior and configures characteristics of behaviors.
Defines a traffic policy and specifies for traffic categories
Applies the traffic policy
Configure L-LSP
Configures reserve address checks
Adds interface to the DiffSer domain
Which of the proceeding operations are required when you configured simple traffic classification?

Exhibit:
