Which of the following commands would NOT check for PowerShell version?

• A. $PSVersion
• B. $PSVersionTable.PSVersion
• C. $PSVersionTable
• D. Get-Command -Name PowerShellVersion

Answer: (D)

The command that would not check for the PowerShell version is the one that references Get-Command -Name PowerShellVersion.

In PowerShell, the $PSVersion and $PSVersionTable.PSVersion are direct ways to retrieve the version of PowerShell currently in use. The variable $PSVersion retrieves a string that indicates the version, while $PSVersionTable.PSVersion provides a more structured object that includes the major, minor, build, and revision numbers of the version. Similarly, the $PSVersionTable command returns a table with detailed information about the PowerShell version, including various related properties, among which is PSVersion.

On the other hand, using Get-Command -Name PowerShellVersion does not actually check or return the version itself. Instead, this command searches for a command or function named "PowerShellVersion". Since no such cmdlet or function exists specifically with that name, it does not provide any version information. Thus, this option is not relevant for checking the PowerShell version.
