I have the following question and I can't the answer out. On one hand, 'erase nvram:' deletes the start config and the router boots in its default setting. But any certificates wouldn't be located in nvram. That's where we keep OS file and other files. Maybe even certificates, whatever certificates the question refers to. Or is this just a bad question?
You’ve recently upgraded a branch office from a Cisco 2610 to a Cisco 2811 and you’ve been requested by management to erase all configurations off the device that are company confidential including certificates. What command would you execute on the old Cisco 2610 series router?
a. format flash:
b. erase flash:
c. format nvram:
d. erase nvram:

Certificates and certificate revocation lists (CRLs) are used by your router when a CA is used. All CRLs are stored locally in a private location folder of NVRAM.

I guess that CCNA test wouldn't have a question like this. I don't seem to ever read about certificates from Cisco Netacademy CCNA material. Still it's good to know. Thanks.
