The command logging trap 3
sets the logging level to severity level 3 on the router, which corresponds to the "Error" level according to the standard syslog severity levels. This means that messages with a severity level of 3 or higher will be sent to the syslog server.
In syslog, the severity levels are as follows:
- 0: Emergency (system is unusable)
- 1: Alert (action must be taken immediately)
- 2: Critical (critical conditions)
- 3: Error (error conditions)
- 4: Warning (warning conditions)
- 5: Notice (normal but significant condition)
- 6: Informational (informational messages)
- 7: Debug (debug-level messages)
Since logging trap 3
includes severity levels 3 (Error), 2 (Critical), and 1 (Alert), the two message types that will be sent to the syslog server from the choices provided are:
- Critical
- Error
So, the correct answer is Critical and Error.
