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)

Exhibit.

As shown in the figure, RTA belongs to AS 100 and has an EBGP neighbor relationship with RTC, RTD, and
TTB is an IBGP neighbor of RTC, RTD, and RTE, and the four router all belong to AS 200.
(Note: The attributed not involved In the question use the default values)
1. Import route 1.1.1/32 from RTA and advertise this route to RTB by way of RTC, RTD, and RTE,
respectively (suppose the three routers between is IGP, EGP, and INCOMPL:ETE, respectively. Whichroute
will RTB prefer?
2. Suppose the preceding policy is retained. Apply inbound routing policies on RTC, RTD, and RTE so that
the values of the MED attribute of route 1.1.1.32 learned by RTB are 40, and 20 respectively. Which route will
RTB prefer?
3. Suppose the preceding policy is retained. Apply an inbound routing policy on RTB so that the values of the
AS_ PATH attribute of route 1.1.1.1/32
Learned from RTC, RTD, and RTE are 10 20 30,and 10 20, respectively. Which route will RTB prefer?
4. Suppose the preceding policy is retained. Apply an inbound routing policy on RTB so that the values of the
local-preference attribute of route 1.1.1.1.32 learned from RTC and RTE are 30 and 120 , respectively. Which
route will RTB prefer.
5. Suppose the preceding policy is retained. Apply inbound policies on RTC. RTD and RTE so that the values
of the preferred-value attribute of route 1.1.1.132 are 50.40 and 30 respectively. Which route will RTB prefer?
