H3C Large-Scale Routing Network Technologies V2.0 Sample Questions:

1. In the topology shown in the figure, the following configurations are performed on RTA and RTB respectively:
RTA-ospf-1-area-0.0.0.1]network 192.168.0.0 0.0.0.255
RTA-ospf-1-area-0.0.0.1]network 192.168.1.0 0.0.0.255
RTA-ospf-1-area-0.0.0.1]network 192.168.2.0 0.0.0.255
RTA-ospf-1-area-0.0.0.1]network 192.168.3.0 0.0.0.255
RTA-ospf-1-area-0.0.0.1]network 192.168.4.0 0.0.0.255
RTB] acl number 2000
RTB-acl-basic-2000] rule 0 permit source 192.168.1.0 0.0.0.255
RTB-ospf-1] filter-polic2000 import
Then the possible routes in the RTC routing table are _____

A) 192.168.1.0/24
B) 192.168.2.0/24
C) 192.168.0.0/24
D) 192.168.4.0/24

2. The networking is as shown in the figure, RTA and RTB are located in AS 100, RTC, RTD, RTE are located in AS 200, AS 100 advertises BGP route 1.0.0.0/24 to AS 200, the main configuration of BGP of RTC and RTD is as follows, if RTE, RTD The interconnect link is interrupted, RTE accesses the 1.0.0.0/24 network segment, which WAN link is preferred?

A) WAN link 2 is preferred, because the preferred-value of RTD is 300
B) WAN link 2 is preferred, because the preferred-value of RTD is 100
C) WAN link one is preferred, because the preferred-value of RTC is 200
D) WAN link one is preferred, because the preferred-value of RTC is 100

3. As shown in the figure, the MSR router of the headquarters is connected to the branch through the Ethernet interface E1/0, and the connection is backed up through the ISDN network. Which of the following options is the most feasible at this time?

A) The OSPF protocol runs on the Ethernet link between the headquarters and the branch. Set a static route, the outgoing interface is Bri2/0, and the priority value is 5
B) The OSPF protocol is run on the Ethernet link between the headquarters and the branch. Set a static route, the outgoing interface is Bri2/0, and the priority value is 0
C) The RIP protocol runs on the Ethernet link between the headquarters and the branch. Set a static route, the outgoing interface is Bri2/0, and take the default priority value
D) The RIP protocol runs on the Ethernet link between the headquarters and the branch. Set up a dynamic routing backup group on the outbound interface Bri2/0

4. Running the displaipv6 interface vlan-interface1 verbose command on a router displays the following information:
Vlan-interface1 current state: UP
Line protocol current state:UP
IPv6 is enabled, link-local address is FE80::2010:1
No global unicast address configured
Joined group address(es):
FF02::1:FF10:1
FF02::2
FF02::1
MTU is 1500 btes
ND DAD is enabled, number of DAD attempts: 1
ND reachable time is 30000 milliseconds
ND retransmit interval is 1000 milliseconds
ND advertised reachable time is 0 milliseconds
ND advertised retransmit interval is 0 milliseconds
ND router advertisements are sent ever600 seconds
ND router advertisements live for 1800 seconds
Hosts use stateless autoconfig for addresses
From the above information, it can be known that _______________.

A) The transmit function of ND RA is not enabled on the Vlan1 interface
B) The multicast addresses monitored by this interface include FF02::1 , FF02::2 , FF02::1:FF10:1
C) The IPv6 unicast address of the Vlan1 interface is only FE80::2010:1, and the global unicast address is not configured
D) Vlan1 interface is boring and IPv6 protocol status is Up

5. In OSPF protocol, when the interface network type is P2P (point-to-point), its default Hello interval and neighbor failure time are ______ respectively.

A) 30 , 120
B) 40 , 120
C) 10 , 40
D) 10 , 30
