I agree,
It's embarrassing for a junior sysadmin not to be able to edit /
manipulate files with VI.
LPIC-1, is base of all Linux Certification, so you need a strong
learning base.
VI and nano, "is like" RHEL / CentOS, SUSE / OpenSUSE, Debian / Ubuntu,
you don't have to be an expert at all, but you need to know how to work
on both (rpm, yun, dnf, zypper, dpkg, apt *, etc).
Need not be "expert" on VI or nano, but know how to edit, save, delete,
insert .... basic edits.

personally don't think this stuff is really worth examining; we
don't examine
people on how to hit the “Enter” key, either.
And yet, I still run into sysadmins who don't know Vi, and are lost in
minimal OS modes, let alone emergency ones. Basically anything where
only Vi is installed, busybox or similar.
I'm talking people who are gurus with OpenShift, OpenStack, RHV, et
al. To me, Vi isn't optional when it comes to interactive sysadmin.
I'm really talking from experience here, and one of the reason I
professionally look for LPIC-1 in addition to RHCSA/RHCE.**
Now if we want to talk about changing LPIC-1 and, subsequently, LPIC-2
with a wholesale shift _away_ from _interactive_ skills, then I'm all
ears. And that would be a far, far more radical change, but I'm open
to that.
**SIDE NOTE: For those not aware, the RHCSA/RHCE certification no
longer requires passing generic RHEL
exams. Red Hat is offering 200/300 alternative exams in things like
OpenShift (e.g., EX210 and EX310) at, and has tipped its hat that
others are coming.
E.g, there's no reason there cannot be a historical 101+102 and a new
set of 111+211 for those who want more of a non-traditional option,
possibly the latter 2 replacing the former at some point, after a
period of concurrent release. Of course, this means a crapload more
work for Fabian, so I'm not one to go there. But just wanted to point
it out.
In other words, what are you going to learn about whether somebody
spent those
10 minutes in vimtutor by asking them three questions, that you
won't learn by
asking them one question?
Yes, just like many other things learned in 10 minutes. ;)
It's about practice and muscle memory from experience, not memorizing.
Again, my argument applies in the context of ... _if_ we are going to
test for _interactive_ skills.
If not, then we're talking a wholesale change in the objectives, not
just Vi. ;)
There are lots of topics on the exam that are more complex,
interesting, and
essential to a junior Linux professional's work and require a lot
more time
than 10 minutes to master that are weighted *way* lower than vi.
One question
on vi should do very nicely and that would free up two weight
points for more
interesting stuff that is actually worth examining (and will also
tell us more
about a candidate's proficiency with Linux).
Maybe I'm an old fart (guilty), but if someone doesn't know Vi, I
don't think they are even a junior GNU/Linux sysdmin capable of
_interactive_ break-fix. Again, personal experience here.
If you're asking me if I'm okay for a 'gimme' set of questions in Vi,
absolutely! If you know Vi, and can answer basic questions, I'll spot
you some great pointage. That's how it supposed to be ... ubiquitous,
common knowledge and application. And beyond that, I made the further
argument that those who don't know Vi in minimal modes, busybox only
situations, etc... are going to be hurting (and calling me over).
That's my case ... _if_ we're talking an interactive sysadmin focused
LPIC-1 program.

Rite of passage.
Because people like me get tired of when junior sysadmins crap a
system, and cannot recover, and call me over and I find out it's
because they use nano. It's a pretty bad day when a Sev 1 results,
and they cannot edit files because they only know nano.
Sorry, but I'm not backing down on this _unless_ we're going to get
away from testing interactive break-fix. It's required knowledge in
my book for break-fix, especially considering minimal modes when
junior admins are on-call, and systems shouldn't be down and awaiting
the senior admins to arrive or get on-line because the junior admin
cannot edit a file.
I'm fine with it being a 'gimme' in points. That's the point, it
should be for those who use Vi day in, day out.
