In an MPLS VPN network, which of the following operations can "ensure that the PE device correctly associates with the corresponding VPN instance after receiving a VPNv4 route"?

• A.Configure the BGP protocol on the CE device and specify the VPN instance.
• B.No configuration is required; the PE device automatically associates with the VPN instance.
• C.Configure a VPN instance on the P device to pass routing association information.
• D.Configure routing policies on the PE device to import VPNv4 routes to the corresponding VPN instance.

In Huawei's WAN bandwidth optimization solution, for "high-definition video surveillance streams transmitted across regions," which of the following technologies can "reduce bandwidth usage while ensuring video clarity"?

• A.H.265-based video compression technology (saving 50% bandwidth compared to H.264)
• B.Transmit the raw video stream directly without compression.
• C.Reduce video resolution, sacrificing clarity for bandwidth.
• D.Reducing the video frame rate causes stuttering.

In an MPLS VPN network, which of the following descriptions conforms to the allocation logic of
"public network labels"?

• A.Assigned by the CE device based on the VPN instance, used to identify the VPN service type.
• B.Fixed to a preset value, not adjusted with changes in network topology.
• C.Assigned by the PE device based on the CE device's IP address, used for VPN instance identification.
• D.Dynamically allocated by PE/P devices via the MPLS LDP protocol, used for backbone network forwarding path identifiers.
