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

1. In the topology shown in the figure, by executing the import-route direct command on the RTA, 192.168.0.0/24 , 192.168.1.0/24 , 192.168.2.0/24 , 192.168.3.0/24 and 192.168.4.0/24 are injected. There are five routes. Now it is required that the above routes cannot be learned on the RTB. What configurations can be performed on the RTA?

A) RTA-ospf-1]asbr-summar192.168.0.0 255.255.0.0 not-advertise
B) RTA-ospf-1-area-0.0.0.1]asbr-summar192.168.0.0 255.255.240.0 not-advertise
C) RTA-ospf-1-area-0.0.0.1]asbr-summar192.168.0.0 255.255.248.0 not-advertise
D) RTA-ospf-1]asbr-summar192.168.0.0 255.255.224.0 not-advertise

2. Based on the topology shown in the figure, which of the following statements about OSPF router types is true is ________.

A) RTB is both a backbone router and an ABR
B) RTD is both a backbone router and an ASBR
C) RTE is not an intra-area router
D) RTA is both an intra-area router and a backbone router

3. Two MSR routers, MSR-1 and MSR-2, are interconnected on the 172.16.16.0/20 network segment. Now it is necessary to configure OSPF protocol on router MSR-1 to establish an adjacency relationship with MSR-2. Which of the following configurations is infeasible? (Select one or more) (Select one or more)

A) MSR-1] ospf MSR-1-ospf-1] area 0 MSR-1-ospf-1-area-0.0.0.0] network 172.16.16.0 0.0.31.255
B) MSR-1] ospf MSR-1-ospf-1] area 0 MSR-1-ospf-1-area-0.0.0.0] network 172.16.16.0 0.0.15.255
C) MSR-1] ospf MSR-1-ospf-1] area 0 MSR-1-ospf-1-area-0.0.0.0] network 172.16.16.0 0.0.255.255
D) MSR-1] ospf MSR-1-ospf-1] area 0 MSR-1-ospf-1-area-0.0.0.0] network 172.16.16.0 0.0.32.255

4. There are a lot of static routes with tags 100 and 200 on the RTA. RTA and RTB run OSPF routing protocol, and RTB needs to learn all static routes on RTA. At the same time, it is required that on RTB, the priority of the route with tag 200 is 200.
If the above requirements are fulfilled, which of the following configurations is incorrect?

A) RTA configuration: route-polic1 permit node 10 if-match tag 100 appltag 100 route-polic1 permit node 20 if-match tag 200 appltag 200 ospf import-route static route-polic1 RTB configuration: route-polic2 permit node 10 if-match tag 200 applpreference 200 ospf preference ase route-polic2 150
B) RTA configuration: route-polic1 permit node 10 if-match tag 100 appltag 100 route-polic1 permit node 20 if-match tag 200 appltag 200 ospf import-route static route-polic1 RTB configuration: route-polic2 permit node 10 if-match tag 200 ospf preference ase route-polic2 200
C) RTA configuration: route-polic1 permit node 10 if-match tag 100 route-polic1 permit node 20 if-match tag 200 ospf import-route static route-polic1 RTB configuration: route-polic2 permit node 10 if- match tag 200 applpreference 200 ospf preference ase route-polic2 150
D) RTA configuration: ospf import-route static RTB configuration: route-polic2 permit node 10 if-match tag 200 ospf preference ase route-polic2 200

5. Running the command on the router and its display information is as follows:
<RTA>displaisis brief
ISIS (1) Protocol Brief Information:
network-entit:
01.1111.1111.1111.00
is-level: level-1-2
cost-ste: narrow
preference: 15
Lsp-length receive: 1497
Lsp-length originate: level-1 1476
level-2 1476
maximum imported routes number: 10000

From the above information, we can know that RTA______.

A) Its Stem-ID is 1111.1111.1111.00
B) Its Stem-ID is 1111.1111.1111
C) is a Level-1 router
D) is a Level-1-2 router
