When RADIUS servers are not reachable, the router falls back to the local database for authentication. In the provided configuration, there are two methods defined under aaa authentication login. The first method list group1 uses the local database where a username is not specified but a password is set to “cisco123”. The second method list group2 specifies the use of RADIUS (group radius) and if that fails, it falls back to local (local). Since RADIUS is not reachable in this scenario, we refer to the local database which does not require a username but requires the password “cisco123”.

The script should be completed with the code that opens a file in write mode for each device and writes the configuration into it in JSON format. Option C is correct because it uses a context manager to open a file named after the hostname variable with a .json extension. It then writes the device variable, which presumably contains the device configuration, into this file using json.dump(), ensuring the data is in JSON format.

Traffic policing is a mechanism used to control the rate of traffic in a network by applying limits to the traffic flow. It can be applied to both incoming and outgoing traffic directions. Policing monitors the data rate and can drop packets that exceed the defined rate or can mark them as out-of-profile for further processing. It ensures that network resources are allocated fairly and prevents any single user or service from consuming excessive bandwidth.
