PowerShell Hands-On Exercises Primer 2

Here are the initial instructions and explanation of the lab environment. Read this while your environment is busy creating itself from nothing. Yes, this violates physics; we know. How fun!

To start this lab, you will examine the process in three fundamental stages. Firstly, you will import a .NET library into the PowerShell environment. Then, you will construct two functions devoted to encoding and decoding string values. Finally, you will secure the two functions further by adding a required key. By the end of this challenge, you'll be able to create functions using .NET components for encoding and decoding string values.

In this challenge, you will gather data on the existing partitions of a computer. Following this, you will extract crucial storage metrics, concentrating on the available versus utilized space. Lastly, you will develop a script that regularly monitors these metrics, empowering you to act when storage reaches critical levels.

Automating backup data security and integrity. You will begin by identifying critical data directories, and will then automate the backup process using PowerShell. By the end of this challenge, you'll have a hands-off, systematic backup process ensuring your data remains intact and retrievable.

You will start with extracting real-time CPU usage metrics and using PowerShell's logging capabilities to record these metrics over time. Wrapping up the challenge, you will institute alerts and notifications for scenarios where CPU usage breaches predefined thresholds. Once done, you'll have a PowerShell script for CPU performance monitoring.

You will now list all existing scheduled tasks and extract key attributes. You will then work with PowerShell to manipulate these tasks, such as starting, stopping, or modifying them. Finally, you will create a report detailing the status of these tasks. By the end of the challenge, you will be able to query and report on Windows automation tasks.

In this challenge, you examine a directory's content and familiarize yourself with its structure. As you progress, you'll develop a PowerShell script capable of parsing the content based on provided keywords. You will then optimize the search function to return results quickly and accurately. At the end of this challenge, you'll know how to search and find what you need when you need it.

Further file management can be done by enumerating all files within a specified directory, and cataloging them based on size. You will do this, and will then filter this list to identify the top 10 largest files. To wrap up, you'll display the output, making the information user-friendly. By the end of this challenge, you'll know how to identify large files within any given directory.

To finish up the lab, you will read a list of computers or IPs from an external file. You'll then integrate the classic ping command within a PowerShell script, measuring the online status of each entry. You'll then compile and display these results in an organized, easy-to-read format. By the end of the challenge, you'll be able to check the connectivity of many devices, streamlining network management.
