Question 1
An empty-configured MSR router is connected to the same OSPF network through multiple interfaces, and OSPF is enabled on all these interfaces. After the configuration is completed, the router has successfully learned the OSPF routes in the network.
Now run the following command on an OSPF interface of the router:
[MSR-GigabitEthernet0/0]ospf cost 256
In the case of keeping other configurations unchanged, the correct understanding of the configuration is _____.
Question 2
On the MSR router, if you want to modify some configuration after logging in to the device at the access level, you can use the ______ command to switch to level 3. (Multiple choice)
Question 3
Two empty-configured MSR routers MSR-1 and MSR-2 are interconnected back-to-back through their S1/0 interfaces, and their GE0/0 interfaces are respectively connected to the client hosts HostA and HostB:
HostA----GE0/0--MSR-1--S1/0---------S1/0--MSR-2--GE0/0----HostB
The versions of the two MSR routers are unified to Version 5.20, Release 1618P11, and the following configurations are made on the two routers:
Configuration on MSR-1:
[MSR-1]interface GigabitEthernet 0/0
[MSR-1-GigabitEthernet0/0] ip address 192.168.1.1 255.255.255.0
[MSR-1]interface Serial 1/0
[MSR-1-Serial1/0] link-protocol ppp
[MSR-1-Serial1/0]ip address 3.3.3.1 255.255.255.252
[MSR-1]rip
[MSR-1-rip-1]network 192.168.1.0
[MSR-1-rip-1]network 3.3.3.1
Configuration on MSR-2:
[MSR-2]interface GigabitEthernet 0/0
[MSR-2-GigabitEthernet0/0] ip address 10.10.10.1 255.255.255.0
[MSR-2]interface Serial 1/0
[MSR-2-Serial1/0] link-protocol ppp
[MSR-2-Serial1/0]ip address 3.3.3.2 255.255.255.252
[MSR-2]rip
[MSR-2-rip-1]network 10.10.10.0
[MSR-2-rip-1] network 3.3.3.1
According to the above configuration, the WAN interface between the two routers can communicate with each other, and the two hosts HostA and HostB can ping the address of their respective gateway GE0/0. Then which of the following statements is correct?
Question 4
The subnet mask of the IP address 132.119.100.200 is 255.255.255.240, so the IP subnet address where it is located is ______.
Question 5
If you want to achieve the entire network interoperability, as shown in the figure, there are 4 ways to divide the OSPF area, which is reasonable? (multiple choice)
