Huawei HCIE-Routing & Switching (Written) V3.0 認定 H12-261_V3.0-ENU 試験問題:
1. In order to allow the routers at both ends of the IPv6 over IPv4 manual tunnel to exchange routing information, OSPFv3 can be enabled on the tunnel. OSPFv3 will be able to form a neighbor relationship normally, and the tunnel interface will be treated as a P2P link interface.
A) TRUE
B) FALSE
2. An engineer uses two routers to test IPv6 services, and simulates the interconnection between headquarters and branches by running BGP4+.
The logical topology of the network is shown in the figure. Regarding the transmission of IPv6 routes between two devices, which of the following statements is wrong?
A) BGP4+ transmits routing information between peers through Update packets
B) When routing is transmitted, it will carry recognized mandatory attributes such as AS_Path
C) If the Update message carries the MP_REACH_NLRI attribute, it means that the advertised route is reachable
D) When routing, the Next_Hop attribute must be an IPv6 global unicast address
3. Which of the following is the correct description of the Register message in PIM-SM? (Multiple choice)
A) Register message enables the RP to learn multicast source information.
B) Register message is sent by the receiver router
C) Register message is sent to the RP by unicast instead of multicast.
D) Register message is sent by the source DR
4. As shown in the configuration, if the administrator configures OSPF on R1 but R1 cannot learn the routes of other routers, what are the possible reasons? (Multiple Choice)
[R1] ospf
[Rl-ospf-1] area 2
[R1-ospf-1-area-0.0.0.2] network 10.0.13.1 0.0.0.0
A) This router is not configured with authentication, but the neighbor router is configured with authentication.
B) The area ID configured by this router is different from the area ID of its neighbor router.
C) This router is not configured with an OSPF process ID.
D) The router's announcement network address does not match the interface mask
5. Which of the following statements are true about IPSec VPN? (Multiple Choice)
A) Two routers can establish OSPF neighbor relationships through IPSec VPN tunnels and exchange intranet routes.
B) Two routers establish IPSec VPN through the main mode. Starting from the fifth packet (including), the payload data is often encrypted.
C) Savage mode can support NAT traversal, while main mode does not support NAT traversal
D) Two routers establish IPSec VPN through aggressive mode, then only two packets are exchanged between the two devices to establish a tunnel.
