H3C Large-Scale Routing Network Technologies V2.0 Sample Questions:
1. In the IS-IS network as shown in the figure, RTA, RTC, RTD, and RTE establish Level-2 adjacency relationship with each other; RTB establishes Level-1 adjacency relationship with RTA and RTC. After the routes of each router are stable, RTB selects the next hop as ________ when accessing 192.168.14.1.
If at this time RTA and RTC are added with the following configurations:
RTA-isis-1]import-route isis level-2 into level-1
RTC-isis-1] import-route isis level-2 into level-1
Then when RTB accesses 192.168.14.1, the next hop is ________.
A) RTA;RTA
B) RTC; RTC
C) RTC;RTA
D) RTA;RTC
2. After the various routers in the figure establish IS-IS neighbor relationships and achieve synchronization, the routers that have sent CSNP messages are ______.
A) RTA
B) RTC
C) RTB
D) RTD
3. Which of the following statements about Route-polic is correct ______?
A) If more than one node is defined in the Route-polic, at least one of the nodes should have the matching mode permit
B) In a node of the Route-polic, at least one if-match clause must be included
C) In the same node of Route-polic, the relationship between different if-match clauses is and
D) In a Route-polic, the relationship between different nodes is or
4. As shown in the figure, RTA has configured each interface address and enabled the NAT-PT function. It is now required to configure a one-to-one static NAT-PT mapping on the RTA, which of the following configurations is correct?
A) RTA]natpt v6bound static 1::3 1.1.1.3 RTA]natpt v4bound static 1.1.1.2 1::2
B) RTA]natpt v6bound static 1::2 1.1.1.3 RTA]natpt v4bound static 1.1.1.3 1::3
C) RTA]natpt v6bound static 1::2 1.1.1.3 RTA]natpt v4bound static 1.1.1.2 1::3
D) RTA]natpt v6bound static 1::2 1.1.1.2 RTA]natpt v4bound static 1.1.1.3 1::3
5. In the IS-IS network shown in the figure, each router is configured as follows.
RTA-isis-1]cost-ste compatible
RTB-isis-1] cost-ste wide-compatible
RTC-isis-1]cost-ste narrow-compatible
Then it is _______ that can correctly calculate the link cost between each other.
A) RTA and RTC
B) RTA and RTB
C) RTB and RTC
D) None
