H3C Large-Scale Routing Network Technologies V2.0 Sample Questions:
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. Five routes, and perform the following configurations on RTA, RTB and RTC respectively:
RTA]ospf 1
RTA-ospf-1]area 1
RTA-ospf-1-area-0.0.0.1]network 10.0.0.0 0.0.0.255

Then the routes that cannot exist in the routing table of RTC are _____
A) 192.168.0.0/20
B) 1.1.1.1/32
C) 192.168.3.0/24
D) 2.2.2.3/32
2. For the NSEL field in the NSAP address, the following description is correct ________.
A) NET can be seen as an NSAP address with NSEL 0
B) NSEL is used to indicate the upper layer protocol type, similar to the Protocol field in the IP protocol
C) NSEL is used to indicate the link layer protocol type
D) In an IP routing environment, the value of NSEL is usually FF
3. Which of the following features is not supported by IPv6 Neighbor Discover?
A) Duplicate Address Detection
B) Path MTU Discover
C) link address resolution
D) Neighbor Unreachable Detection
E) route redirection
F) Stateful address autoconfiguration
4. After executing the displaospf interface command on the MSR router RTA, the router output is as follows:
From the above output, it can be judged that ________.
A) RTA is elected as DR in the network segment where this interface is located
B) The Router ID of OSPF process 1 of RTA is 2.2.2.2
C) The OSPF network type of the current interface is Broadcast
D) The IP address of the current interface is 192.168.1.1
5. Regarding the comparison between OSPF protocol and RIPv2 protocol, the following statement is correct
A) OSPF protocol supports VLSM, while RIPv2 protocol does not support
B) Both protocols are common IGP routing protocols, and both support automatic aggregation by class
C) RIPv2 uses hop count as routing metric, and OSPF protocol cost (cost) as routing metric
D) Both protocols support routing information triggered updates
