You are capturing logs to troubleshoot an issue with IS-IS; however, the logs are Increasing In size too quickly. Referring to the exhibit, which configuration statement would solve this problem?
The logs are increasing in size too quickly due to the amount of information being captured. One way to control the size of the logs is to eliminate tracing of normal operations, which include routine events that do not provide much insight for troubleshooting specific issues. By deleting the 'normal' trace flag, the log file size can be significantly reduced as only specific events such as 'hello' messages and 'packets' will be logged. Therefore, removing the 'normal' trace flag is the best option to control log file size effectively.
Why not A? Ref: traceoptions (Protocols IS-IS) | Junos OS | Juniper Networks "traceoptions (Protocols IS-IS) ... Options ... Global Tracing Flags ... normal—All normal operations, including adjacency changes ..." Wouldn't it be useful to avoid tracing "normal" operation and log only "hello" and IS-IS protocol packets, to save disk space and have lighter log files?
it's not D but B. B is the correct answer
B should be correct.
B is correct

I believe A is correct answer
I think it´s D. Because the other ones do not really make sense (got that confirmed by one of our engineers)
you are using the default size which is 10 files D is not correct ^_^
The default value for the number of log files stored for IS-IS tracing is not 10. The default value is 5. Therefore, if you want to limit the number of log files to the default value, you don't need to add any additional configuration statement. If you want to change the default value and set it to 10, you can use the following configuration statement: set protocols isis traceoptions file files 10 This configuration statement will limit the number of log files stored for IS-IS tracing to 10.
According to this, the default is 10, not 5. https://www.juniper.net/documentation/us/en/software/junos/is-is/topics/ref/statement/traceoptions-edit-protocols-isis.html
Option B would solve this problem: set protocols isis traceoptions flag hello detail. By specifying the detail flag, only detailed logs related to IS-IS hello messages will be captured, reducing the amount of data being logged and the rate at which the logs increase in size.
we have other trace options in place and this will save the file size.
D. set protocols isis traceoptions file files 10 This configuration statement limits the number of log files that are stored for IS-IS tracing to 10. By specifying a maximum number of log files, you can control the amount of storage space consumed by the logs and prevent them from growing indefinitely.
B is the correct answer
A option saves file size.
