Nearly all system administrators and IT support engineers concur that Microsoft’s PowerShell is incredibly powerful and is swiftly emerging as their go-to tool for automating tasks and saving time while managing their infrastructures. Some people would also be quick to mention the PowerShell community, which is quite helpful.
There are undoubtedly certain advantages to being able to demonstrate that you have a specific degree of skill, but certification can be burdensome in other areas. Eventually, the discussion turns to the subject of whether or not PowerShell should become a certified skill.
What is PowerShell Certification?
You can obtain, add, modify, clear, and destroy certificates and certificate stores using the PowerShell Certificate provider.
The certificate stores and certificates on your computer are organized in a hierarchical namespace called the certificate drive.
PowerShell is a free and open-source command-line interface (CLI) program that enables DevOps experts, IT administrators, and developers to automate processes and configurations.
Built using Microsoft.NET technology, PowerShell is a bifunctional tool. PowerShell is an open-source shell that may also be used as a scripting language. A command-line interface specific to the operating system is used in conjunction with PowerShell as a shell to control the computer using commands. In addition to the graphic user interface (GUI), which is used to transmit commands from a user to an operating system, another interface preference is the command-line interface.
PowerShell may be used to automate repetitive tasks thanks to its shell capabilities. This facilitates labor and lowers the likelihood of mistakes. Each command line is also immediately preserved, making it simple to recreate it whenever necessary.
PowerShell is a programming language used as a scripting language to transfer commands from one software to another. The PowerShell scripting language is handled like machine code, unlike other programming languages ??like Ruby, Python, etc.
Instead of using a compiler, a PowerShell interpreter reads commands line by line. With the help of this feature, the parent program’s functionality may be enhanced. Tasks can be automated, data can be extracted from data sets, management can be set up, etc.
PowerShell: How Does It Operate?
Because it was created using the.NET framework, PowerShell generally performs more like a programming language than a command-line program. PowerShell operates on objects, and everything in it is an object. These items stand for either instructions or qualities (methods). Even better, they can be set to run continuously throughout the program as an input or output. PowerShell has four different sorts of commands that it uses to manipulate things.
1. Cmdlets
The fundamental single-function PowerShell commands are known as cmdlets, which are pronounced: “command-lets.” The letters of each word in a paragraph, which is what PowerShell is, are represented by cmdlets. They can be used separately to complete a task or in combination to complete more important tasks. Keep in mind that each cmdlet continues to function independently to contribute to the combined function’s cmdlet output.
Cmdlets, however, are not created in PowerShell. They are translated into PowerShell after being compiled in another language. PowerShell cmdlets are essential since the developer’s imagination determines the extent of their functionality. Developers and DevOps engineers can use “pipes” to send an item from one cmdlet’s output to another’s input.
2. Powershell functions
One of the many commands used in PowerShell to run scripts is the function command. Functions are written in the PowerShell language, as opposed to cmdlets. They consist of a series of instructions that can be invoked to accomplish a task. It takes parameters as input, but it has two output options: it can display the output on the user’s screen or pipe it to another function or cmdlet input.
The power shell has two functions: basic and advanced. The simplest type of PowerShell function is called the basic function. There are no inherent or inherited features with fundamental functions. The body of the function is contained exclusively within a set of curly brackets. Advanced functions are those that, at their heart, contain the characteristics of a basic function but also have additional features.
3. Powershell Scripts
Cmdlets are used to create PowerShell scripts. Using these scripts, several tasks can be automated. In a PowerShell script, there are three different sorts of commands. The first command used to retrieve data from a file system is “get.” The windows component information can be changed using the “set” command. This includes giving various components varied qualities. The “remove” command is used to entirely remove actions. PowerShell scripts simplify the authoring of code and other automation-related use cases.
4. Executable commands
The commands needed to operate executable files are known as executable commands. Executable files are Microsoft Windows program components that contain the.exe extension. When running.exe files, there are three commands that are used. The “Invoke-expression” command is the first method. This is possibly the most common way to run these files.
The “start-process” cmdlet is the second command. While starting several processes on your device, this command yields the same outcome as the first command. The third choice is to add a period (“.”) before the filename. Although this is the simplest approach, all alternatives launch the.exe file.
PowerShell: Why Is It Used?
1. Making task automation possible
Task automation in DevOps is the first of these causes. PowerShell is mostly utilized for automating tasks as a scripting language. Each and every PowerShell use case includes automation. Because of PowerShell’s distinct format structure, automation is produced primarily in that language but also in other scripting languages. Another reason PowerShell is a superior choice is that it can be expanded with new functions, classes, cmdlets, and modules.
2. Facilitating access to data
Access to data is another factor in PowerShell’s appeal. Administrative tasks make up a sizable portion of PowerShell use cases. Many services operate independently and are managed by a central IT administrator in large computer networks. The IT administrator has quick access to various network services data repositories, such as file systems or registries, using PowerShell.
3. Taking control of “infrastructure as code”
Thirdly, PowerShell has a management framework that enables users to use configuration as code to manage the infrastructure of their business. Desired State Configuration is the name of this framework (DSC). Managers and IT administrators learn PowerShell skills so they can push and pull configuration models for easy composability as needed. These abilities are also required in order to obtain repeatable deployments, enforce configuration settings, and produce declarative setups.
4. Making remote instructions easier
The fact that PowerShell makes remote commands possible is another reason why it has such a high acceptance rate and use case. Software or technologies that permit remote work are becoming increasingly popular as remote use becomes the new gold rush. Administrators can remotely manage numerous systems using PowerShell. This is made possible by the WS-management protocol and Windows Management instrumentation.

Benefits of using PowerShell
Although there are several scripting languages ??and different shells, PowerShell as a standalone component has advantages that make it the “professional choice”. The main advantages of PowerShell for the user are:
1. Adaptable format system
By using PowerShell, the user can easily format their input and get the output they want. Three formatting options are available in PowerShell. Each method is easily adaptable to the situation the user needs.
“Form Wide” is the original format technique. When using this method, the user sees only one object property. It can be used to create lists or fill columns in tables. Another method is the “Format list”. This technique allows the user to list the properties of an item, with each property displayed on a separate line. The “format sheet” is on the third side of the mold. Users can easily render the output as a table this way.
2. Integrated data formats
PowerShell is capable of storing, transferring, and converting data into formats that are both machine- and human-readable. Comma-separated value (CSV), JavaScript Object Notation (JSON), and Extensible Markup Language are these data formats (XML). Table data is stored as plain text in the built-in CSV data format. Each file is separated from the next in this format by a comma.
Instantaneous communication between a browser and a client is accomplished using the JSON format. It is both a human-readable and open standard format. The “Invoke-WebRequest” or “Invoke-RestMethod” commands can be used to transform information from the web into PowerShell data. The XML format may be read by both computers and people.
3. Extensive type system
PowerShell’s Extensible Type System (ETS) allows script and cmdlet developers to work with .NET objects.
Utilizing the PSObject object, this system is completed. There are two ways to extend object types using the PSObject object. The PSObject object in the first method displays various views of particular object kinds. We refer to this as an adapted view.
The PSObject object in the second method offers a way to extend an existing object by adding members. By adding new members, the base object—the original object being worked on—expands by receiving new data that can be helpful for scripting.
4. A secure scripting tool
PowerShell’s configuration management capabilities allow users to control security.
Users can select which scripts to put through a visual review using this functionality. Given that dangerous scripts are difficult to spot visually, customers might benefit from automated security policies.
One of PowerShell’s security measures is the usage of an execution policy. The circumstances under which PowerShell will run particular configuration files and scripts are established by this execution policy. While the Windows platform is where this policy is used, Group Policy settings allow it to apply to a wide variety of computers and devices.
This policy, however, is only in effect at the user’s discretion. PowerShell only executes scripts that have been given an identifying name when it is made active.
5. Development that is self-service
Each team in an Exchange is able to independently create its own cmdlets thanks to PowerShell. Comparing this to other solutions has a big advantage. This “self-service” paradigm is essential because it enables developers to construct the administration of their features even as they create their features.
Better management and superior products follow from this. Because component teams that are “in charge” of their features are most effective, products benefit from this. Thus, a well-organized feature is guaranteed for the users. Additionally, because genuine codes can be tested on features early on, it speeds up construction. In the process of creating features and scripts, this removes bottlenecks.
6. Reliable API
Windows is known for using APIs like Windows Management Instrumentation (WMI) and Component Object Model (COM) that are inconsistent or insufficient. As a result, they are ineffective in transporting requests to and from browsers.
However, PowerShell is an API that third parties use that is entirely comprehensive and consistent. This is the Power Shell’s REST API. Utilizing the “Invoked-RestMethod” cmdlet, it is activated. Just request it via HTTP or HTTPS to activate it. An API request will be made to retrieve data from the URL.
7. Simple automated
To run the activity, PowerShell uses a simple one-time command tool. Cmdlets are single-purpose tools that can be used alone or in combination to accomplish complex tasks. PowerShell includes over ninety basic cmdlets. Developers can add other cmdlets as needed. Since PowerShell is an open-source feature, these custom cmdlets can also be distributed to others. Developers can easily create automation through the management of monotonous tasks.
Developers have an advantage over others if they understand how to build these cmdlets. Because of this advantage, the PowerShell toolkit provides users with a “pro option” in various situations.
8. Composability between products
PowerShell is appropriate for a variety of services and products thanks to its excellent cross-product composability concept. This suggests that PowerShell can be used for many services while still being under the control of a single IT administrator. This enables PowerShell to operate in networks, such as a corporate network, where different services are dependent on or independent of one another.
9. Simple information access
PowerShell can open data that is difficult to access, despite the fact that all command lines can access the computer’s file system. PowerShell is based on the Microsoft.NET framework, which explains this. With the help of this special function, IT specialists can automate and remotely manage each Windows PC connected to a business network. IT administrators can have complete visibility and control over every file system in their network with only one line of command-line code.
10. Management of corporate networks
Despite being the primary management interface for corporate Microsoft Office 365, PowerShell includes a number of helpful administrative commands that are missing from the latter. The pre-set password option is an illustration of a command. Either every user changes their password on a regular basis, or no user changes their password, is an option on the admin website. An IT administrator can create a 2-factor authentication (2FA) system using PowerShell to stop users from frequently changing their passwords.
11. Detectability
The Get-command cmdlets are one of PowerShell’s most useful features. With the help of this command, both end users and programmers can learn about the vast array of capabilities and commands offered by PowerShell. Get-command compiles a list of every cmdlet and function that is currently available on that PC. PowerShell aliases can be used to conveniently locate these nicknames or short forms for certain cmdlets. This supports users in using the program on a daily basis, regardless of expertise or knowledge.
12. Information about the Microsoft certification tests
Even while most people might not see this as a benefit, it nonetheless plays a significant role for individuals. PowerShell-specific questions have just been added by Microsoft to their certification examinations. You may not need to be familiar with every command’s whole syntax, but you should be able to see how various commands can be used in various situations. Because of this, choosing PowerShell over other tools can be a better option for people preparing to take a Microsoft Azure DevOps certification test.
Pitfalls of PowerShell
Framework: The.NET Framework is necessary.
Object-based: The text-based commands are used with the majority of shells to complete tasks when creating scripts. A user will need to adjust to a different way of thinking if they migrate from another form of the shell to Windows PowerShell. As a result, some people require additional time to learn PowerShell.
Security risks: Using PowerShell has the additional disadvantage of perhaps posing certain security vulnerabilities. It is a popular method used by IT experts to connect remotely to other servers and devices. PowerShell may leave some security gaps open during this procedure. It is one of the main drawbacks of PowerShell script usage.
Web Server: PowerShell also has the issue of requiring users to run a web server on their computer.
5 Microsoft Certs That Absolutely Require PowerShell
True Windows administrators can be distinguished from hackers using PowerShell. It’s cmd.exe on steroids, the administrator’s ideal tool for managing servers more quickly from the keyboard than by navigating windows and snap-ins with a mouse. It is a strong scripting engine that outperforms batch files. Additionally, Microsoft has been promoting it as the go-to tool for administrators. When you’re prepared to advance, enroll in our Advanced Windows Server course to step up your game.
Microsoft certifications now place an increasing amount of emphasis on PowerShell. These days, you won’t do well on exam day if you don’t know at least the fundamentals of PowerShell and important cmdlets.
Windows Server 2016 MCSA
We’re going to take a few PowerShell-related objectives and required abilities from each exam’s Microsoft exam description to get a sense of how PowerShell fits into the subject matter. MSCA on Server 2016 is seen below.
Admins and power users may automate activities in Windows with the aid of PowerShell, which was its original purpose. Given this, it is not unexpected that PowerShell knowledge is required for this certification. Regarding PowerShell’s use in the MSCA: Windows Server 2016 tests, Microsoft is extremely clear. Another excellent option is to research the relevant cmdlets, then just start performing any daily operations that you would typically perform with GUI tools. Though first more difficult, it will eventually become second nature. You’ll acquire the materials required for the test.
Productivity MCSE
Because it covers a variety of topics, the MCSE: Productivity certification can be thought of as a “jack of all crafts.” Even though PowerShell isn’t specifically tested in the exam, you should be familiar with it.
PowerShell can significantly enhance SharePoint management, a program with a less-than-stellar admin interface. Using scripts and cmdlets rather than the cumbersome admin website makes managing sites much easier and faster. But learn about those cmdlets, especially for managing users and groups. They should come in handy to ace the test, we think!
The administrator of Azure, Microsoft Certified
The PS extension Azure PowerShell was created specifically for PowerShell because it is so essential to Azure. It follows that learning PowerShell is a prerequisite for receiving this certification.
When one simple cmdlet can create new resource groups, deploy a new VM from a template, and move local data into cloud storage, why navigate through endless screens of menus? Also, scripting? From the gateway, put it behind you.
It’s simple to set up a lab at home and prepare for tests: Install Azure PS, create a new free Azure account, and then avoid using the admin portal. Storage, virtual machines (VMs), load balancers, and SQL databases can all be used to create an app using Azure.
The Mobility MCSE
For large, globally dispersed enterprises that require uniformity in their workstation configuration, patch management, and inventory, System Center is a potent tool. The system administrator can save their lives by automating this activity across huge groups of workstations. Running System Center is a beast, but PowerShell is up to the task. Like other tests, knowing those cmdlets before the test will pay off if you have experience using them in your lab or in the real world.
The administrator of Modern Desktops, Microsoft 365 Certified (Office 365)
Although Microsoft doesn’t specifically include PowerShell in the certification exam goals, we can’t exclude the possibility that these tests contain inquiries about the caliber of your cmdlet capabilities.
Joining the domain, installing applications and devices, and configuring local passwords can all be very frustrating during workstation installations. Even group policies struggle to handle these tedious chores effectively.
This is a big test that covers a lot of terrains, but PowerShell Remoting, which enables you to magically execute PowerShell across the network from the comfort of your desk, will be a crucial component. There won’t be any shocks caused by PS on your exam if you learn it and the important workstation management cmdlets.
PowerShell is a crucial tool for any administrator in charge of a Microsoft stack, which should come as no surprise. Knowing PowerShell is essential for automating your cloud environment, managing hundreds of workstations, and completing even the most challenging (or boring) jobs.
Microsoft is promoting PowerShell because it has been a major goal in several of its exams. Knowing PowerShell is therefore a given moving forward if you want to increase your admin authority.
