Huawei HCIE-Routing & Switching (Written) V3.0 認定 H12-261_V3.0 試験問題:

1. When the BFD detection time intervals at both ends are 30ms and 40ms respectively. Which of the following options is correct?

A) bfdSession can be established. each at its own time interval
B) bfdSession could not be established
C) bfdSession can be established, after negotiation 30ma
D) bfdSession can be established, after negotiation 40ms

2. [R1]ospf 1
[R1-ospf-1]area 2
[R1-ospf-1-area-0.0.0 2] network 10.0.13.1 0.0.0.0
As shown in the configuration, the administrator has configured OSPF on R1, but R1 cannot learn the routes of other routers, so the possible reason is ().

A) This router's advertised network address does not match the interface mask
B) The area ID configured by this router and the area I of its neighbor routersD is different
C) This router is not configured with the authentication function, but the neighbor router is configured with the authentication function
D) This router does not have an OSPF process ID configured

3. As shown in the figure, an enterprise hopes to realize the secure mutual access between the head office and each branch through MPLS/VPN, and requires that the VPN traffic of the branches must be forwarded through the head office to monitor the traffic. Which of the options described in this solution is wrong?

A) BGP packets can be used to exchange VPN routing information between CEs and PEs
B) Spoke- Establish an MP-IBGP peer relationship between PEs to exchange VPN routing information.
C) Hub-CE and When the Hub-PE transmits routing information, the Hub-PE It is necessary to configure a route that allows the receiving AS number to be repeated once to receiveRoutes advertised by the Hub-CE
D) Hub-CE and Hub-PE, Spoke-PE with Spoke-CEs can use OSPF to exchange routing information

4. There is a network consisting of router R1, router R2, router R3 and router R4. The 4 routers are interconnected through a LAN network. All 4 routers have basic oSPF deployed. When you execute the command "display ospf peer" on the router R2, find the router R2 and the route

A) Router R2 is DR or BDR
B) Router R3 is not a DR, nor a BDR
C) router there is no full adjacency between R2 and router R3
routerR4 is DR
D) device the state between R3 is "2-way". So what can you conclude from this output?
Router R2 is not a DR

5. in command aggregateate ipv4-address { mask | mask-length } [as-set I attribute-policy route-policy-name1 ldetail- suppressed I origid-policy route-policy-name2 |suppress-policy route-policy-name3], multiple parameters can be used toAffects summary routes and their results. Which description is correct about this command?

A) If As is configured-set, the AS_PATH of the summary route contains the AS path information of all specific routes to prevent routing loops
B) If Supp is configuredress-policy also generates aggregated routes. The if-match clause in Route-policy is used to select suppressed detailed routes. Detailed routes matching the Route-policy will still be advertised to other BGP neighbors
C) If Attrbute-policy is configured, you can change the attributes of the aggregated route
D) If Origin is configured-policy, only with Route Only the detailed routes matching the policy can participate in the aggregation
