I am starting a class for a Linux RHCSA certification. No job guarantee. Just a certification.

You will acquire following skills after the training :

Understand and use essential tools for handling files, directories, command-line environments, and documentation
Operate running systems, including booting into different run levels, identifying processes, starting and stopping virtual machines, and controlling services
Configure local storage using partitions and logical volumes
Create and configure file systems and file system attributes, such as permissions, encryption, access control lists, and network file systems
Deploy, configure, and maintain systems, including software installation, update, and core services
Manage users and groups, including use of a centralized directory for authentication
Manage security, including basic firewall and SELinux configuration
Ability to diagnose as well as address permissions problems and SE Linux policy violations
Configuration of local storage using logical volumes and partitions
Managing groups and users including focusing on the use of centralized directory for authentication
Using VNC and ssh for accessing remote systems
Locating and reading on-line documentation using info, man, and files in /usr/share/doc
Proper management of system resources like identifying memory/CPU intensive processes, adjusting process priority
with renice, and kill processes
Managing security including using or installing basic firewall and SELinux configuration
Creation and configuration of file systems and attributes like encryption, permissions, network file systems, and access control lists.

I highly recommend to start in the IT career getting a certificate.

Cost of the training is $300.00 ( which includes lectures, practice exams, lot of training videos). Serious candidates only.
