How can you ensure a router logs data to a remote Syslog server?

1. Enable logging

2. Configure a source interface

3. Set up an IP address for the Syslog server

4. All of the above

The correct answer is: All of the above

To ensure a router logs data to a remote Syslog server, several steps must be taken, which encompass all the options mentioned. First, enabling logging is essential as it activates the mechanism that allows the router to send log messages to external systems. Without this step, the router would not generate or send any logs regardless of other configurations. Second, configuring a source interface is crucial as it determines which interface on the router presents the log messages. This is particularly important in scenarios where the router has multiple interfaces, as the source IP address for the Syslog messages is derived from this configured interface. This helps the Syslog server know where the logs are coming from. Finally, setting up the IP address for the Syslog server is vital as this directs the log messages to the correct destination. Specifying the server's IP address in the configuration enables the router to know where to send its logs. Thus, all these actions must be taken together for the logging to function properly. This is why selecting the option that includes all the steps (enabling logging, configuring a source interface, and setting up an IP address for the Syslog server) is the comprehensive approach needed to ensure successful logging to a remote Syslog server.
