Question 1
If you configure syslog messages without specifying the logging trap level, which log messages will the router send?
A. error conditions only
B. warning and error conditions only
C. normal but significant conditions only
D. all levels except debugging
E. informational messages only
Answer: D
Explanation
Syslog levels are listed below
| Level | Keyword | Description |
| 0 | emergencies | System is unusable |
| 1 | alerts | Immediate action is needed |
| 2 | critical | Critical conditions exist |
| 3 | errors | Error conditions exist |
| 4 | warnings | Warning conditions exist |
| 5 | notification | Normal, but significant, conditions exist |
| 6 | informational | Informational messages |
| 7 | debugging | Debugging messages |
The highest level is level 0 (emergencies). The lowest level is level 7. By default, the router will send informational messages (level 6). That means it will send all the syslog messages from level 0 to 6.

Default level is 7 and not 6. The question doesn’t have the right answer.
I just had a look at Cisco website, and it seems that 2960 devices still have level 6 as the default for trap messages, and level 7 for console, monitor and logging to a file on the flash.
Router(config)# logging trap level
Specifies the kind of messages, by severity level, to be sent to the syslog server. The default is informational and lower. The possible values for level are as follows:
Emergency: 0
Alert: 1
Critical: 2
Error: 3
Warning: 4
Notice: 5
Informational: 6
Debug: 7
Be default, syslog servers receive informational messages and lower.
