Huawei H12-831_V1.0-ENU 問題集

質問 1：
A campus has deployed IPv6 for service testing. There are 4 routers (R1, 22, R3 and R4) in this network, running 0SPFV3 to realize the interconnection of IPv6 network. A new router R5 needs to be connected to the network for testing. An engineer introduces a direct route in the OSPFVV3 process of R4 so that devices in the campus network can access the GE0/0/1 port address of R5. Which of the following statements about the scene is true of?

A. R4will generate aType5 LSAdescribe bowIenteredIPv6routing prefix
B. R2will generate aType4 LSAdescribeR4ofRouter ID
C. R4will generate aType5 LSAonly inArea 1internal flooding
D. R2will generate aType4 LSAonly inArea 0internal flooding
正解：A,B,D

質問 2：
A company consists of a head office and two branch offices, and uses MPLS VPN technology to transmit private network routes. In the networking mode of HuB&Spoke.

質問 4：
A campus has deployed IPv6 for service testing. There are 4 routers in the network, running 0SPFv3 to implement IPv6 network interconnection. As shown in the figure, an engineer checked the LSDB of R2 and intercepted one of the Link-LSAs. Which of the following statements is true about the description of this LSA?

A. The SA shows 2 does not support external routing, but participates in IPv6 routing calculation
B. The router that generates this LSA is R2 port R2 connected
C. The link-local address of R2 interface GEO/0/0 is: FE80::2E0:FCFF:FEC, D:4F79
D. IPv6 address prefix for GEO/0/0: 2001:DB8:2345:23::/64
正解：B,C,D

質問 5：
The rules of RR advertising routes violate the rules of IBGP split horizon, so it may cause loops in the AS road. Which routing attributes does RR use to prevent loops?
A. Cluster List
B. AS-PATH
C. Nexthop
D. Originator ID
正解：A,D

質問 6：
OSPF is deployed in a campus to achieve network interworking, and OSPF is also enabled on the GEO/0/2 interface of R3. Area1 is deployed as an NSSA area, and the device addresses are shown in the figure. An engineer configures a static route on R3 to access the loopback interface address of R4, and imports the static route in the 0SPF process. At this point, in the Type5 LSA received by R1, the forwarding address (FA) is____. (Note: Please fill in the IP address without mask)

正解：
(10.1.23.2)
