I feel ready for the OPS235 exam. There are a few areas I need to brush up on, but overall I feel I have a grasp  of most of the course content.

Strengths

• CentOS installation
• KVM administration via GUI
• Package/software installation and updates
• tar and file archiving/management
• fstab and partition management

Weaknesses

• Knowledge of specific commands and arguments/switches (rely on man pages)
  • iptables syntax
  • lvm commands
• CentOS/RedHat-specific commands and conventions (used to Debian/Ubuntu)
• SELinux
• Memorization of .conf file structures

Exam review topics

• KVM network configuration
• User and group management
