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. > - linux skills to administer a small cluster My view: HA > - able to describe user impersonation and why it is needed > - able to set up ldap (users, groups) > - able to set up kerberos (kdc) 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. > - able to set up a traditional relational database (used to store schema > information for several services) > - able to set up HDFS (distributed FS) My view: Storage exam, especially DBs to support infrastructure > - able to set up Hive (distributed database) > - able to set up Kafka (distributed messaging) > - able to set up Zookeeper (resource locator akin to DNS) > - plus probably a few more servers. > I mentioned this on the devops track, not a traditional ops track, since I > can see people moving into from the cloud environment instead of a > traditional datacenter environment. > > I agree the exams should be as agnostic as possible.

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. - bjs _______________________________________________ lpi-examdev mailing list [email protected] http://list.lpi.org/cgi-bin/mailman/listinfo/lpi-examdev
