RedHat 135 course (Week 2)

So much like week 1, the day started with intros and just general talk about Linux experiences. Most of the people from this class were also in the week 1 class I attended 2 weeks ago. A lot of the other students seem to be having a hard time grasping concepts.
Day 1
So far, I have learned more than I did in week 1. A lot of command line tasks to complete. Most of the Linux experience I have is all through using ssh and the CLI. So this really isnt that difficult for me so far. We covered 4 chapters on day 1. I will break them down here.
Chapter 1 - Automated Installation of Red Hat Enterprise Linux
Day 2
Day 2 went in depth in a few things. I feel like I learned some more as well as really solidified the concepts and objectives that are to be covered on the exam.
Chapter 5 - Network Configuration and troubleshooting
Day 3
Chapter 8 - Accessing Network File Sharing Services.
Chapter 10 - Network Users Accounts with LDAP

Are the questions like... Create a file named test1.txt and make it read-only to everyone?
Itll be something like
Create user 1
Add user 1 to group 1
Or find all files and list them in this file.
Pretty easy to understand. They arent trying to trick you.
Per the RHCSA exam objectives,
So, yeah, it's on the objectives and needs to be known.
Next up: eventually the RHCE and to start blogging again.

It's needed indirectly, just like KVM.
Let's say you want to share a file via ftp or http. If you copy file to the ftp/http root dir it should automatically inherit right SE Linux context. But if you move it, you'll need to correct context manually. So it depends.
Also, there are few bugs in SE Linux policy that one should be aware off and know workarounds. I think autofs service, and root password change in single user mode are affected.
Yes, I am taking it on March 30th.
I came across this today and thought it might be of interest regarding SELinux.
