To provide a final opportunity to practice some of what you have learned in this course, we have designed a case study in which you will put into practice what you have learned.
In the last module of this course, you will complete a series of exercises in which you respond to scenarios and troubleshoot various problems that occur within a fictitious company.
Within each exercise, we provide various resources, such as company information, user information, user history, and system architecture, which will help you with each task. You can access these items from a case file that looks like this:

You are one of the two Linux system administrators for the newly formed ValWare Corporation.
ValWare specializes in Web-enabling legacy mainframe applications for large Fortune 500 clients. ValWare uses proprietary software developed in-house for this purpose. ValWare currently has three Linux servers, thirty Linux workstations for developers, and a few Windows clients for management personnel.
Your job is to work with a fellow system administrator to manage user and group accounts, to maintain the filesystem including making sure your backup policy is followed, and to handle server security. ValWare is growing rapidly and you and your system administrator colleague have been continually adapting the servers to meet the changing needs of the company. The next module will start the course by introducing you to Red Hat Linux and the Internet.
