Red Hat retired courses free publication for general public

[cyb3rx]

As the old courses like RH254 and many more are retired why don't Red Hat make these courses & guides publicly available as they are of no use for exam now, I got this idea while watching this demo video on youtube 

I always feel difficulties when searching about old technologies which is not being covered in today's RHCSA/RHCE courses, like NIC Teaming, BIND, iSCSI, Samba, iptables etc. 

organizations still using these technologies how can I learn in depth about these technologies, few days ago I was searching for iptables, being today's RHCE I know about ansible automation platform I know about firewalld but I don't have strong base of iptables, iSCSI, BIND...  

how can I get old versions of student/study guides to learn about these technologies?

PS: documentations are different, it does not provide in depth guidance as student guide does

Two comments here... the exam contents are NOT retired, they are part of the RH358 / EX358 exam curriculum, as shown here: https://www.redhat.com/en/services/training/ex358-red-hat-certified-specialist-services-management-a... . 

As per the documentation itself, it is still freely available under the Red Hat Enterprise Linux documentation at : https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/9 .

358 still not cover NIC Teaming & iptables,

student guides are not comparable with documentations

The exam objective shows:

* Manage Firewall Services

Configure system firewalls to allow access to specific services or ports
Configure system firewalls to allow or deny access from only specific network domains or IP subnets.

That's firewalld (and its backend, nftables. IPtables is deprecated as of RHEL9 )

* Manage Link Aggregation
Create a network team interface consisting of two network interfaces
Make a network team interface persistent across boots
Assign a network address to a network team interface
Configure a teamd runner.

As you can see, that is still included. However, it has been deprecated in RHEL9 , as per the RHEL 9.0 release notes at: https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/9/html-single/9.0_release_not... . 

"""The teamd service and the libteam library are deprecated. As a replacement, configure a bond instead of a network team."""
