"Erase nvram" and "erase startup-config", do these two commands do exactly the same thing?
Do we have to issue any other commands to get rid of more things to re-configure a route?

Yes, those two commands have the same result. The erase startup-config is the older method, erase nvram: is the newer, recommended command. At least according to Odom. I trust him.

To be honest I didn't even know about erase nvram and erase startup-config. I probably used them originally but now I always use "write erase" I don't know anyone who does otherwise.Lab:

Where did you learn "write erase". The command doesn't make sense to new learners like me, just like many other puzzling IOS commands.
I'm with Cisco Netacad. The chapter didn't mention "write erase" at all. Would Cisco expect us to know or use "write erase"? -

write erase is old school.. in fact that command isnt even in NXOS so I wouldnt worry about it.
There are alot of old or even "hidden" commands in IOS.. -

It's not even supported in the exams as far as I remember.
It's the same as write instead of copy run start. I don't know anyone who does copy run start, we just do write. If you know about write, then write erase makes sense.
write isn't supported though in NX-OS. As far as I remember, they are old commands... though I much rather use them than the alternatives "wr" is much easier to type than "copy r s".
So my answer would be, no Cisco don't expect you to know this for exams.Lab:

LOL, all this drove me nuts. When I was learning to configure routers, switches, and ASA's the commands seem never consistant, or at least in my opinion. It can really get the mind going all over the place.2012/2013 Certification Goals:

It's just a stupid concept of Cisco about their exams. They want you to learn syntax that in real world many times is not in use...
Many of their commands that they force you to learn for the CCNA exam are uncomfortable and/or too long etc... I mean, why should you write:
write running-config startup-config
when you can just simply type
wr
...? -

But you wouldn't write copy running-config startup-config -- you would do copy r s
If you really want to write every letter than use the tab key
