In the OSPF network shown in the figure, the network engineer found that the Router ID configuration of R1 and R2 is the same, and both R1 and R2 have introduced the default route (default-route-advertise always). Which of the following descriptions of this scenario is wrong?
- A . R1 and R2 can establish a neighbor relationship
- B . R2 and R4 can establish a neighbor relationship
- C . A routing loop may occur between R3 and R4
- D . R1 and R3 can establish a neighbor relationship
In the network shown in the figure, adjacent routers use directly connected interfaces to establish EBGP neighbor relationships. The Router ID of each device is 10.0.XX, and the AS number is 6500X, where X is the router number. R1 and R4 both have static routes to 192.168.1.0/24, which are introduced into BGP through import.
Which of the following statements are correct by default? (Multiple choice)
- A . The traffic path from R3 to 192.168.1.0/24 is R3-R2-R1
- B . The traffic path from R5 to 192.168.1.0/24 is R5-R4
- C . The traffic path from R2 to 192.168.1.0/24 is R2-R1
- D . The traffic path from R6 to 192.168.1.0/24 is R6-R5-R4
In the IS-IS network shown in the figure, the link cost value has been marked in the figure. R1 turns on IS-IS Auto FRR, then the main path for R1 to reach 10.0.3.3/32 is R1-R2-R3, and the backup path is R1-R4-R2-R3.
- A . True
- B . False
When the device logs in to other devices as an SSH client and fails to log in using public key authentication, which of the following are possible reasons? (Multiple choice)
- A . The user public key stored on the server is wrong
- B . The client does not enable the first authentication function
- C . Missing local key pair
- D . The server private key saved on the client is wrong
In the OSPFv3 network shown in the figure, the OSPFv3 related parameters are the default configuration. When checking the LSDB on one of the devices, some content is omitted in the LSDB. The Router IDs of R1, R3, and R4 are 10.0.1.1, 10.0.3.3, and 10.0.4.4 respectively. The Origin Router part of some LSAs is hidden. Please complete this part.
The R2 device has the file information shown in the figure. When the network engineer uses the "dir|include4" command to view the file information, which of the following files will be seen? (Multiple choice)
- A . 3.zip
- B . 2.cfg
- C . 4.zip
- D . 3.dat
In the OSPFv3 network shown in the figure, area 1 is a stub area, area 2 is a common area, and area 3 is an NSSA area. The IPv6 address of the R6Loopback0 interface is 2000::6/128. The Router ID of each device is 10.0.XX, where X is the device number.
Which of the following descriptions is wrong?
- A . The R4 LSDB contains the Inter-Area-Prefix-LSA describing 2000::6/128 generated by R2.
- B . The Inter-Area-Prefix-LSA describing 2000::6/128 generated by R2 exists in R1’s LSDB.
- C . The R6 LSDB contains the Inter-Area-Prefix-LSA describing 2000::6/128 generated by R3.
- D . The R5 LSDB contains the Inter-Area-Prefix-LSA describing 2000::6/128 generated by R1.
In a BGP/MPLS IP VPN network, routing between CE and PE devices can only be established through IGP or BGP protocol.
- A . True
- B . False
The AS-External-LSA generated by a router is shown in the figure. Based on this LSA, which of the following descriptions are correct? (Multiple choice)
- A . The router ID of the router is 10.0.3.3
- B . The cost value of other routers to reach 2000::3 is always 1
- C . This LSA is generated by converting NSSA LSA
- D . The Route Tag value carried by this LSA is 1
When a device is abnormal or fails, it will generate a variety of information. According to the severity or urgency of the information, the information is divided into 8 levels. Which of the following has the highest severity level?
- A . Informational
- B . Debugging
- C . Notification
- D . Warning
