Question

Scenario: While using the GUI, a Citrix Administrator discovers that a Citrix ADC MPX appliance is unresponsive. The administrator needs to force a core dump for analysis and restart the appliance.

What can the administrator do to accomplish this?

A. Use the reset button on the front of the appliance.
B. Connect to a USB port to issue a restart command.
C. Use the non-maskable interrupt (NMI) button on the back of the appliance.
D. Turn off the appliance using the power button.

Answer

C. Use the non-maskable interrupt (NMI) button on the back of the appliance.

Explanation

If a Citrix ADC MPX appliance becomes unresponsive while a Citrix Administrator is using the GUI, the correct way to force a core dump for analysis and restart the appliance is to use the non-maskable interrupt (NMI) button located on the back of the appliance.

Pressing the NMI button triggers the appliance to save the current state of memory to the hard disk drive as a core dump file before restarting. This allows the issue that caused the appliance to become unresponsive to be diagnosed by analyzing the core dump.

The other options presented, such as using the reset button on the front, connecting via USB to issue a restart command, or turning the appliance off with the power button, would restart the appliance but fail to properly generate a core dump of the system state for troubleshooting. Only the NMI button achieves the stated goals of forcing a core dump and restarting the appliance.

Therefore, the correct answer is C. Use the non-maskable interrupt (NMI) button on the back of the appliance.
