Scenario: A Citrix Administrator is troubleshooting a Citrix ADC issue. The administrator goes to the command line and from the Shell, tails the ns.log to view the log in real time to find the issue. After a few minutes, the administrator noticed that the logs stopped scrolling and the issue was missed.

How can troubleshooting continue using the ns.log?

A. The ns.log needs to be downloaded to the client machine for full viewing.
B. The ns.log service has stopped and needs to be restarted.
C. The ns.log is still running. Press ‘Enter’ and the ns.log will resume.

D. The ns.log has reached its 100 KB limit. Press ‘CTRL+C’ to stop it from running and issue the command “tail-f ns.log” to resume.
