In the IS-IS network shown in the figure, R1 introduces the default route through the "default-route-advertise always level-1" command. Which device is the next hop corresponding to the default route in R3’s routing table?
- A . R3
- B . R4
- C . R1
- D . R2
The OSPF protocol requires routers in the same area to save the same link state database LSDB. As the number of routes on the network continues to increase, some routers cannot carry so much routing information due to limited system resources. This state is called database overload.
If all routers in an OSPE network are configured with "Isdb-overf1low-limit number 7", which of the following scenarios may cause the router to enter the Overflow state? (Multiple choice)
- A . The number of Type 5 LSAs exceeds 7
- B . The number of Type 3 LSAs exceeds 7
- C . The number of Type 4 LSAs exceeds 7
- D . The number of Type 7 LSAs exceeds 7
Network engineers found that the multicast client could not receive multicast data correctly, so they suspected that the group address set by the multicast server was wrong. Which of the following cannot be the group address?
- A . 232.0.0.18
- B . 224.0.0.1
- C . 233.0.0.2
- D . 224.0.1.5
As shown in the figure, the message is forwarded based on MPLS in the network. When PE2 receives the message sent by P2, which of the following is the label value carried in the message?
- A . No label
- B . 1033
- C . 3,1033
- D . 3
Advanced ACL defines rules based on information such as source IP address, destination IP address, IP protocol type, TCP source/destination port, UDP source/destination port number, etc. Using routing policies to call advanced ACL can achieve BGP routing control.
- A . True
- B . False
A BGP router receives a BGP route whose AS_Path attribute is "100200300".
If the router wants to reject this route, which of the following as-path-filters can it use? (Multiple choice)
- A . ip as-path-filter l deny.*
- B . ip as-path-filter l deny 200
- C . ip as-path-filter l deny 00$
- D . ip as-path-filter l deny 00.*30
A campus network is connected through Huawei S series switches. The administrator has enabled the MAC drift detection function in the network. Which of the following descriptions of this function is wrong?
- A . This function can report alarms, including MAC address, VLAN, hop interface and other information
- B . If loops may occur only in a few VLANs in the network connected to the switch, it is recommended to configure the subsequent action to withdraw the interface from the VLAN instead of turning the interface Down.
- C . After the switch turns on this function, it can integrate the MAC address drift information of the entire network and report the alarm
- D . This function can provide interface protection actions, such as making the jump connection four Down to achieve automatic loop breaking
As shown in the OSPF network, the area numbers are marked in the figure, where area 1 is a common area, area 2 is a Totally NSSA area, and area 3 is an NSSA area. R5 introduces the external route 10.0.5.5/32 into OSPF.
Which of the following routers have a route entry for 10.0.5.5/32 in their routing tables? (Multiple choice)
- A . R2
- B . R3
- C . R4
- D . R6
A certain enterprise network is shown in the figure, in which CE and PE communicate with each other by deploying EBGP. At this time, CE1 transmits a private network route to PE1.
what are the errors in the following analysis of this scenario? (Multiple choice)
- A . If no additional measures are taken, CE3 will discard the route.
- B . If the commands peer 10.1.1.1 soo 200:1 and peer 10.1.2.1 soo 200:1 are configured on PE1, CE2 will receive the route.
- C . If the command peer 10.1.3.1 substitute-as is configured on PE2, CE3 will receive the route
- D . If you want CE3 to successfully receive the route, you need to configure the command peer 10.1.1.1 soo 200:1 on PE1.
