A factory switch failed and will not boot. The replacement must be rebuilt from a copy of the configuration that was stored somewhere other than that switch. Which practice makes the rebuild possible?
Select an answer to reveal the explanation.
Short Explanation
The box that held the recipe will not turn on, so the recipe had to live somewhere else. You rebuild from a configuration backup that was stored off the switch while it was still healthy. A drawing of the cables and a picture of the wireless signal do not contain the startup configuration.
Full Explanation
A configuration backup stored off the device is what lets you load a known configuration onto a replacement when the original will not boot. The factory switch is dead, so the practice that makes the rebuild possible is that off-box copy, taken while the switch was healthy. The running configuration of a switch that will not boot is not readable. Depending on it leaves you with a blank replacement. A cable diagram records physical runs. It does not contain VLAN, routing, or management configuration. A wireless heat map records signal. It does not store a startup configuration. Exam caveat: the backup has to be recent. A copy from before the last approved change will restore an old network. Operational check: after the replacement boots, load the backup, compare it with the last approved change, and confirm the factory VLANs and the management address return. Load the backup onto the replacement and compare it with the last approved change. Store the backup where a dead chassis cannot take it with it, and date the file so you know which change it includes.
