Question 26

According to this picture, we can judge:

  1. R1 is configured with regional authentication
  2. The device type of R1 is Level-1
  3. The device type of R1 is Level-2
  4. R1 has configured the routing domain authentication

Question 27

According to this picture, we can judge:

  1. The device type of R3 must be Level-1-2
  2. Unable to determine the device type of R3
  3. The device type of R3 must be Level-1
  4. The device type of R3 must be Level-2

Question 28

The IS-IS neighbor between R3 and R1 is not established. According to the information in this figure, what is the possible cause?

  1. The IIH certification of R3 and R1 failed
  2. The System ID of R3 and R1 are duplicated
  3. The IS-Level of R3 and R1 do not match
  4. The circuit-type of the interconnection interface between R3 and R1 does not match

Question 29

The network administrator A wants to use ACL to match only the four routing entries 1, 3.5, and 7 in the figure. How many ACL rules does the network administrator A need to configure at least?

  1. 2
  2. 1
  3. 4
  4. 3

Question 30

As shown in the figure, an engineer uses 4 routers to test branch network interoperability. Among them, R1, R2, and R3 in branch 1 deploy OSPF to achieve network interoperability. R2, R3, and R4 in branch 2 deploy IS-S to achieve network interoperability. Now the engineer wants to realize the loopback address of R1 to R4. Which of the following operations can meet this requirement?

  1. In the OSFF process and the IS-IS process of R2, respectively advertise the default route
  2. No configuration is required
  3. Advertise the default route only in the IS-IS process of R2
  4. Advertise the default route only in the OSPF process of R2
