As long as it's Open Source, it's has merit for inclusion, in my
individual, peer view.  Then it just becomes both an 1) Market survey
/ popularity question and 2) a matter of SME's to write objectives
and, ultimately, exam questions.

So, again, 100% my individual views here (speaking only as myself, as
a peer) ...

This is why I'm wondering if a Storage-centric 300 exam is warranted,
allowing more coverage of content, and allows more room in any HA
and/or Virtualization exams.

My view:  HA

My views:

Client/library-level LDAP and Kerberos is already 200-level.  This
should include basic setup of ...
 - [OpenLDAP] ldapsearch/ldapmodif and LDIF aspects
 - [MIT] kinit/kadmin usage
 - SSSD (which has made it into 300 level as well), realmd, etc...

Sever-level LDAP and Kerberos setup should be replaced by FreeIPA**
 - FreeIPA's schema should be the baseline -- e.g., in addition to
standard IETF user/groups ... SSH Keys, Sudoers, Certificates etc...
 - Coverage of other schema should be justified, if in widespread use
 - I.e., FreeIPA is using most of the standards -- e.g., in addition
to 389 (which FreeIPA uses as its LDAP), SSH, Sudoers, etc... schema
feature support are the same in OpenLDAP and eDirectory too.
 - Advanced usage can still be included, but it needs to be justified,
if in widespread use (things FreeIPA doesn't do)
 - I.e., beyond basic setup/usage (that should be 200 level)

We don't want a FreeIPA exam, that would be too Red Hat-centric.  But
FreeIPA's schema and related services should be the 'baseline' as it
takes so many standard tools and unifies them.  It also does
Multi-Master Replication, and is a heck of a lot easier to setup than
even 389 (or any other LDAP).

>  - able to set up SSL (for Kerberos + SSL configs)

My views:
 - We definitely want to cover OpenSSL certificate management
 - And we definitely want coverage of k* tools, however ...
 - If we start looking all sorts of combs, then FreeIPA also does
Kerberos + SSL management

It's key we test admins for the tools, so they can troubleshoot.  But
when we start getting fancy, I think FreeIPA would be better to cover.

I.e., there's a reason Microsoft tests basic AD, but not AD-LDS or
AD-FS, in its base exams.  FreeIPA is the AD for the IETF/POSIX world.

My view:  Storage exam, especially DBs to support infrastructure

My view:  There's more than enough to justify a 300 level Storage
exam.  It just becomes a matter of Open Source, Market
Survey/popularity and available SMEs/objective-exam writers.

As always, just my views, as a peer individual.
