Adaface Sample PowerShell Questions

You're tasked with dynamically invoking functions based on their names stored in an array. Additionally, you're required to filter out functions that have the term "Admin" in their name. Your colleague suggests the following approach:

Assuming no other functions are defined in the session, which of the following will $results contain after executing the script?

You're analyzing a script designed to interact with a remote API. The script fetches data, processes it, and then ensures that all temporary files are deleted. You come across the following code block:

After a successful data fetch, the script occasionally throws the custom error. When this happens, what will be the output and state of the system?

A: The output will display "Network error
            B: The output will display "General error
            C: The script will exit without any output due to the custom error, but the temporary file will be deleted.
            D: The output will display "General error
            E: The script will terminate prematurely, not executing the finally block.

A server you are working on has the PowerShell execution policy set to "Restricted", preventing scripts from running. You need to execute a script named "Deploy.ps1". You recall a technique to bypass the execution policy without changing it permanently. Which of the following methods would allow you to run "Deploy.ps1" without permanently altering the execution policy?

A: Set-ExecutionPolicy Unrestricted -Scope Process; .\Deploy.ps1
            B: PowerShell -ExecutionPolicy Bypass -File .\Deploy.ps1
            C: Invoke-Command -ScriptBlock { .\Deploy.ps1 }
            D: Start-Process PowerShell -ArgumentList "-ExecutionPolicy Unrestricted", "-File .\Deploy.ps1"
            E: Import-Module .\Deploy.ps1

You're reviewing a script designed to automate server maintenance tasks. One requirement is to log every action and potential error for auditing purposes. The script utilizes Start-Transcript and Stop-Transcript cmdlets to capture the session. Here's a snippet:

After several successful runs, you notice that some logs are missing crucial information regarding errors. Which of the following could be a reason for the missing error details?

A: The -Append parameter is causing overwritten logs.
            B: Not all errors are displayed in the console, hence not captured by the transcript.
            C: The Stop-Transcript cmdlet needs to be invoked with an -ErrorAction Continue parameter.
            D: Transcription only captures standard output, not error streams.
            E: The log file path should be specified again in Stop-Transcript.

You're optimizing a script for performance by leveraging runspaces to execute tasks concurrently. Each runspace is supposed to increment a shared counter object. Here's your setup:

You expect the $global:counter to be 5 after all runspaces complete. However, it's not consistently reaching that value. What's the most probable reason for this behavior?

A: Runspaces can't access global variables.
            B: The counter increment operation is not thread-safe, leading to race conditions.
            C: The runspace pool size is limiting the number of concurrent operations.
            D: The $global:counter initialization should be inside the script block.
            E: The runspace pool's Close and Dispose methods are prematurely terminating the runspaces.
