Refer to the exhibit.

Which statement about Hub & Spoke MPLS VPN is false?
A . If two Spoke sites are connected to the same Spoke PE, they must be assigned to different VPN instances to prevent them from exchanging routing information.
B . The route of traffic from Spoke site 1 to Hub site 2: Traffic enters Hub site 3 through an interface under VPN1-Hub of the Hub PE and is then forwarded to Spoke site 2 through an interface under VPN1-Spoke of the Hub PE.
C . The route of traffic from Spoke site 2 to Hub site 1: Traffic enters Hub site 3 through an interface under VPN1-Spoke of the Hub PE and is then forwarded to Spoke site 2 through an interface under VPN1-Hub of the Hub PE.
D . The Hub PE can advertise aggregate Spoke site routes or default routes to Spoke PEs through VPNv4.
E .Routes advertised by a Spoke PE to Spoke site 1 of the Hub PE may be advertised back by the Hub PE through a VPNv4 neighbor.

If a route is imported to the routing table of VRF 1, which VRF can the route match?(A)

RTA is a leaf router that directly connects to host A through interface GigabiteEthernet 1/0/0. The interface is
configured as follows:

Hos a sends a IGMPv2 Report message to group 2321.2.3. Which entry can be displayed by the displayed by
the igmp ssm-mapping group command?

As shown in the figure, the mapping between links and administrative groups is as follows:
0x0F for A -> B; 0xFF for B -> C; 0xF0 for A -> C; 0xC3 for B -> D; and 0x3C for C -> D.
It is expected to configure a tunnel (affinity: 0x0C; mask: 0xFF) on node A to connect to RTD. Which path will be created along with the tunnel?

As shown in the figure, basic BGP/MPLS IP VPN configuration has been completed on routers. Which of the following configurations is incorrect for advertising default routes in VPN instances on the SPE?
Note: All configurations are performed on the SPE.
