Question 26

The two routers of the customer are connected back-to-back through V.35 cables, and the PPP protocol is running on the V.35 interface, and the following interface information is available on one of the routers:
[MSR-Serial0/0]display interface Serial 0/0
Serial6/0 current state: UP
Line protocol current state: DOWN
From the above information, it can be inferred that ______. (Multiple choice)
  • Question 27

    Which of the following options are the features of 802.1x authentication based on MAC address? (multiple choice)
  • Question 28

    The WAN interface S0/0 of the customer's two routers MSR-1 and MSR-2 uses the PPP protocol, and the routers learn the routes from each other by configuring RIP. The following configuration is available on MSR-1: rip 1 network 0.0.0.0 import -route static # ip route-static 0.0.0.0 0.0.0.0 Serial0/0 Then the wrong explanation about this configuration is ______.
  • Question 29

    The main link of the WAN of a company's MSR router is a synchronous and asynchronous serial port, which is connected to the operator's network through a V.35 cable; the router also uses an ISDN BRI interface as a backup link.
    Regarding the line bandwidth, which of the following statements are correct? (multiple choice)
  • Question 30

    Two MSR routers implement dynamic routing learning through OSPF. On one of the routers MSR-1, there are three interface IP addresses 192.168.8.1/24, 192.168.13.254/24 and 192.168.29.128/24, so they must pass a network Command to start OSPF on these three interfaces, which of the following configuration is feasible? (multiple choice)
