H3C Large-Scale Routing Network Technologies V2.0 認定 GB0-381-ENU 試験問題:

1. In the IPV6 stateless address auto-configuration, the PC can get the RA message of the router in the following ways

A) PC receives the RA periodically sent to FF02::1 by the router
B) PC receives NA periodically sent by router to FF02::1
C) PC actively sends RS to FF02::2, requesting RA from all routers on the link
D) PC actively sends NS to FF02::2 to request RA from all routers on the link

2. As shown in the figure, RTA has established IBGP peer relationship with RTB, RTC and RTD. When RTA advertises routes to these three IBGP peers, it uses a unified filter 3001, which is implemented through peer groups.
To achieve the above purpose, the administrator configures the RTA as follows:
RTA-BGP]group in internal
RTA-BGP]peer in connect-interface Loopback0
RTA-BGP]peer 10.0.0.2 group in
RTA-BGP]peer 10.0.0.3 group in
RTA-BGP]peer 10.0.0.4 group in
RTA-BGP]peer in filter-polic3001
Then in the above configuration statement, the error is ______

A) RTA-BGP]peer 10.0.0.2 group in RTA-BGP]peer 10.0.0.3 group in RTA-BGP]peer 10.0.0.4 group in
