Question 722 of 952 from exam 200-125: Cisco Certified Network Associate Exam

D

The correct answer is A. show reload.

The command "show reload" reveals the last method used to powercycle a router. When a router is reloaded, the reload reason is stored in the configuration register, which is a 16-bit value that controls various aspects of the router's boot process.

The "show reload" command displays the contents of the reload log, which contains information about the last reload of the router, including the time and date of the reload and the reason for the reload.

Some of the common reasons for a reload are:

• Manual reload: This occurs when an administrator issues the "reload" command to restart the router.
• Power failure: This occurs when the router loses power and is subsequently restarted when power is restored.
• Software crash: This occurs when the router experiences a software error and needs to be restarted to recover.
• Hardware failure: This occurs when a hardware component in the router fails and the router needs to be restarted to recover.

By using the "show reload" command, network administrators can quickly determine the reason for the last router reload and take appropriate action if necessary.
