Realistic Environment

Get comfortable with the remote desktop environment before the exam to ensure you don't waste any valuable time. For example, practice how to copy and paste from the Terminal, access the Terminal/commands, etc.

Time is limited during the real exam, and if quick actions are essential, there are preparation steps, such as setting aliases or configuring vim, that can help you save time. We've included a section to guide you through these essential optimizations.

Note: In the actual exam, you won't have access to this practice mode. This feature is specifically designed to help you prepare and build speed before you take the test.
