H3C GB0-381-ENU Exam Syllabus Topics:

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

Question 1

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. RTB
C. RTD
D. RTC

Question 2

E As shown in the figure, RTB and RTC each learn EBGP route N from RTD, RTB is missing LOCAL_PREF is set to 200, IBGP neighbor relationship is established between RTA, RTB and RTC through loopback, in the RTA routing table, only N, RTB and RTC are The loopback and RTA itself are directly routed. If RTB goes down due to power failure, can route N be switched to RTC immediately on RTA?

A. Yes, because the neighbor relationship between RTA and RTB is broken, RTA immediately switches to RTC
B. No, because RTA and RTB establish IBGP neighbor relationship through loopback address. If the interconnection interface is improved, it can be switched up
C. No, because the neighbor relationship between RTA and RTB will not be interrupted until the holdtime expires, and it will take about 3 minutes to switch over.
D. Yes, because the next hop of the route N pointing to RTB is unreachable, RTA immediately switches to RTC

Question 3

In the topology shown in the figure, the following configurations are performed on RTA, RTB, RTC and RTD respectively:
RTA] ospf 1 router-id 1.1.1.1

RTB] ospf 1 router-id 2.2.2.2
RTB-ospf-1] area 0
RTB-ospf-1-area-0.0.0.0] network 192.168.1.0 0.0.0.255
RTB-ospf-1-area-0.0.0.0] network 2.2.2.2 0.0.0.0
RTB-ospf-1] area 1
RTB-ospf-1-area-0.0.0.1] network 192.168.2.0 0.0.0.255

RTC] ospf 1] import direct
RTC-ospf-1] area 1
RTC-ospf-1-area-0.0.0.1] network 192.168.2.0 0.0.0.255
RTC-ospf-1-area-0.0.0.1] vlink-peer 2.2.2.2
RTC-ospf-1] area 2
RTC-ospf-1-area-0.0.0.2] network 192.168.3.0 0.0.0.255
RTD] ospf 1 router-id 4.4.4.4
