Question: 118
When using routing policy for route filtering, which will be denied when the router prefix matching the following IP- Prefix? (Multiple Choice)
A . 1.1.1.1/24
B . 1.1.1.1/32
C . 1.1.1.1/26
D . 1.1.1.2/16
Question: 119
The community attribute of the route set through routing policy, does it affect route routing?
A . Indirectly, the route can be classified by setting the Community property of the route, and then different route routing related attributes such as Local_Pre, MED, etc. can be set according to the category, thereby affecting the purpose of route selection.
B . Can’t be affected because the Community attribute of the route is non-transitional and can’t be passed between routers.
C . Indirectly, the route can be classified by setting the community attribute of the route, and then different route selection related attributes can be set according to the categories. These attributes can only include Local_Pre and MED, thus affecting route selection.
D . After the router receives a route update with the community attribute No_Advertise, it will not be advertised outside the local A
Question: 120
The master-slave relationship of OSPF neighbors is negotiated through DD packets. A . True
B . False
Question: 121
The following is a partial output configuration of the Huawei router. The correct description about the configuration of this part is:
A . When the router advertises its own BGP routes to BGP neighbor 12.12.12.2, it will be allowed to advertise routes from 10.0.0.0 to 10.255.255.255.
B . When the router advertises its own BGP routes to BGP neighbor 12.12.12.2, it will allow advertisement of routes from 172.16.0.0 to 172.31.255.255.
C . When the router advertises its own BGP routes to BGP neighbor 12.12.12.2, it will filter out the routes from 172.16.0.0 to 172.31.255.255.
D . When the router advertises its own BGP routes to BGP neighbor 12.12.12.2, it filters out all routes.
Question: 122
When a router running BGP receives a route with an unreachable next hop, what should I do? A . Send an error message to the router that issued the Update.
B . Refused to join the BGP routing table and silently discarded.
C . Receive the route and add it to the BGP routing table. But this route will not be preferred by BGP and will not join the IP routing table.
D . Receive the route, join the BGP routing table, and participate in the BGP routing rules. It may be optimized as the best route and join the IP routing table.
Question: 123
OSPF supports multiple processes that can run multiple different OSPF processes on the same router, and they are independent of each other. Routing interactions between different OSPF processes correspond to routing interactions between different routing protocols.
A . True B . False
Question: 124
In the static LACP mode, the correct description of the active link selection is: (Multiple Choice)
A . After a member interface is added to the Eth-Trunk in static LACP mode, the member interface sends the information negotiation active port about the system priority, system MAC address, interface priority, and interface number to the peer.
B . The higher the system LACP priority is, the higher the priority is. At both endsI of the devices, select the system with the larger LACP priority value as the active end. If the system LACP priority is the same, select the one with the higher MAC address as the active end.
C . The passive end device determines the activity interface based on the active end interface LACP priority and interface ID (interface number).
D . The interfaces selected by two-end device are inconsistent and the data can be forwarded normally.
Question: 125
The OSFF NBMA network requires that routers in the network must select DR and BDR; otherwise, they can’t work.
A . True B . False
Question: 126

A . Forwarding B . Discarding C . ALTE
D . NONE
Question: 127
A . On the 10.0.192.0/8 network segment, the route with a mask length of 18 will be matched to the prefix list, the matching rule is allowed.
B . On the 10.0.192.0/8 network segment, the route with a mask length of 19 will be matched to the prefix list, the matching rule is allowed.
C . On the 10.0.192.0/8 network segment, the route with a mask length of 20 will be matched to the prefix list, the matching rule is allowed.
D . On the 10.0.192.0/8 network segment, the route with a mask length of 21 will be matched to the prefix list, the matching rule is allowed.
Question: 128
In multicast network environment, if IGMPv2 hosts and IGMPv1 routers (hereinafter referred to as version 2 host and version 1 router) are co-located on the same LAN, how do they work together?
A . version 1 router treats the IGMPv2 report as an invalid IGMP message type and ignores it.
B . When version 1 router is a valid IGMP querier, the version 2 host must send an IGMPv1 report.
C . When Version 2 host detects that the IGMP Querier is Version 1 router, it must always respond with the IGMPv1 report.
D . When version 2 host leaves, it still sends an IGMP leave message, and the message can’t be suppressed.
Question: 129
The following statement about OSPF neighbor information:
A . The router ID of this router is 1.1.1.1 B . The neighbor’s router ID is 2.2.2.2
C . The address of DR is 10.1.1.1 D . This router is Master
