Q267. B As shown in the figure, RTA, RTB, and RTC run OSPF, and the process number is 100; OSPF process 200 runs between RTA, RTB, and RTD. The cost of all interconnected links is set to 10. Set the external route priority of OSPF 100 on RTA and RTB to 190, and import an external route 172.16.1.0/24 into OSPF 100 on RTC. Both RTA and RTB are configured to import OSPF100 routes into OSPF200.
According to the above scenario analysis, the following description about RTD learning external routing 172.16.1.0/24 is correct.

There are two equal-cost routes to 172.16.10.0/24 on RTD, and the next hop points to RTA and RTB respectively

There is a route to 172.16.10.0/24 on RTD, and the next hop must point to RTA

The route of 172.16.10.0/24 cannot be learned on RTD

There is a route to 172.16.10.0/24 on RTD, and the next hop may point to RTA or RTB

Q268. The role of IP Internal ReachabilitInformation CLV in IS-IS packets is ______.

Area code carrying IS

Carry the Stem-ID information of IS

Carry the IP address information of the IS-IS interface enabled

Carry IP prefix information, that is, IP routing information

Q269. Which of the following methods for route filtering are feasible?

By filtering routing protocol packets

By filtering routing information carried in routing protocol packets

For OSPF, route information calculated by filtering LSDB

For OSPF, pass Type 3 LSA

Q270. In the IS-IS network shown in the figure, RTB is configured with route aggregation.
So which of the following routes are included in the IS-IS routing table of RTC?

172.16.1.0/24

172.16.2.0/24

172.16.3.0/24

172.16.0.0/22

Q271. About the difference between system policy routing and interface policy routing. The correct statement is _________

System policy routing only works on local packets, not on forwarded packets

System policy routing affects both locally generated packets and forwarded packets

Interface policy routing only works on forwarded packets, not on locally generated packets

Interface policy routing works on both locally generated and forwarded packets

Q272. Regarding the LSDB in the OSPF protocol, the following statement is correct is ________.

The function of LSDB is to record all the link state description information received by the router

There are as many LSDBs as there are areas in the router, and the link state description information received from different areas is stored in separate LSDBs

After completing the LSA exchange, the LSDBs of the routers in the same area should be consistent

When the route changes, the router should first update its own LSDB according to the update message received, and then update the routing table

Q273. Which of the following statements is true in the alliance deployment shown in the figure?

Execute the bgp 65002 command on RTA to start the BGP process, and execute displabgp peer on RTE, you should see the EBGP neighbor RTA belonging to AS65002

Execute displabgp peer on RTA, you can see that RTB is an IBGP neighbor, and RTC is an EBGP neighbor.

Assuming that the RTE advertises the route 10.1.1.0, the RTD will see that the AS-PATH attribute of the route is ( 65002 ) 100 .

Compared with the reflector, a disadvantage of confederation is that all routers must support confederation, so RTB and RTD must be configured with confederation id and confederation peer-as and other related commands.

Q274. In the regular expression, the local route is ________.

Graphical answer 1

Graphical answer 2

Graphical answer 3

Graphical answer 4

Q275. The networking is as shown in the figure, eBGP runs between AS 100, AS 200, and AS 300, and ATM links between RTC and RTA, and RTC and RTB are connected. 2M line as backup, how to implement it on RTC?

No need to adjust BGP properties, RTC will automatically select the path with high bandwidth

RTC filters all BGP routes learned from RTA and accesses AS 100 through AS 200

RTC filters the MED attribute from BGP, the MED of the route learned from RTA is set to 200, and the MED of the route learned from RTB is set to 100

Adjust the BGP LP attribute on RTC, set the LP of the route learned from RTA to 100, and set the LP of the route learned from RTB to 200

Q276. IS-IS protocol messages are divided into IIH, CSNP, PSNP and LSP. These four message classifications are identified by ______.

Link layer header

IS-IS general header

IS-IS dedicated header

CLV

Q277. In the network shown in the figure, the default next hop of PTA is RTC, and the configuration of PBR is as follows:
policy-based-route pbr_a permit node 10
if-match acl 3000
appldefault output-interface serial 2/0
policy-based-route pbr_a dennode 20
According to the above configuration, what is wrong about the data stream matching Acl 3000 on the RTA?

When all links in the network are normal, the message will be sent to PTC

When all links in the network are normal, the packet will be sent to PTB

When the PTA and PTC link fails at the same time, the packet will be discarded

When the PTA and PTC link fails at the same time, the message will be sent to the PTB

Q278. ND protocol packets are encapsulated by _______.

IPv6

IPv4

Ethernet

PPP

ICMPv6

Q279. Among the following statements about BGP load sharing, the correct one is ______.

BGP does not support load sharing, only IGP supports responsible sharing

It is possible to form equal-cost routes by learning the same route from EBGP and IBGP neighbors at the same time

IBGP supports equal-cost routing, EBGP does not support equal-cost routing

BGP only performs load balancing on routes with the same AS_PATH, ORIGIN, local preference, and MED

Q280. Drag and drop

1.1.1.1

2.2.2.2

3.3.3.3

192.168.1.1
