Consider the following PowerShell command: Cmdlet Which of the following BEST describes the actions performed by this command?

Setting the execution policy uses the Set-ExecutionPolicy cmdlet to change the script permission level and does not involve downloading or running any remote content.

PowerShell commands that combine Net.WebClient with DownloadString or use Invoke-WebRequest alongside Invoke-Expression (IEX) fetch and execute scripts hosted on remote systems entirely in memory. This technique is commonly used in post-exploitation to pull payloads without writing files to disk. The command performs network retrieval and in-memory execution of remotely hosted code rather than operating on local resources.

Running an encoded command uses the -EncodedCommand flag with a Base64-encoded string passed directly on the command line, which is a distinct technique from fetching and invoking a remote script.

Instantiating an object using New-Object creates a .NET object in memory but does not by itself perform the retrieval and execution of remotely hosted script content.
