The answer is Invoke-Command. This cmdlet is the correct choice because it is specifically designed for PowerShell remoting, allowing a technician to execute script blocks or commands on one or more remote computers from a local management workstation and return the results to the local session. In the CompTIA A+ Core 2 220-1202 exam, this question tests your understanding of remote administration tools and how to automate tasks across a domain without needing physical access to each machine. A common trap is confusing Invoke-Command with Enter-PSSession, but remember that Enter-PSSession creates an interactive remote session, whereas Invoke-Command runs a one-off command or script and collects output—perfect for piping to Export-Csv. A helpful memory tip: think of Invoke-Command as “fire and forget” for remote scripts, while Enter-PSSession is like sitting at the remote computer’s keyboard.
220-1102 Scripting Basics Practice Question
This 220-1202 practice question tests your understanding of scripting basics. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A technician is writing a PowerShell script to retrieve the IP configuration of all computers in a domain and output the results to a CSV file. The script must run on a management workstation and target remote machines. Which cmdlet should the technician use to execute commands on remote computers?
Correct. Invoke-Command runs a script block on one or more remote computers and returns results, perfect for gathering data from many machines.
B
Enter-PSSession
Why wrong: Incorrect. Enter-PSSession starts an interactive session with a single remote computer, not suitable for scripting across multiple machines.
C
Get-WmiObject
Why wrong: Incorrect. Get-WmiObject can query remote computers but is deprecated in favor of CIM cmdlets. It also doesn't handle complex script blocks as easily as Invoke-Command.
D
Out-File
Why wrong: Incorrect. Out-File writes output to a file on the local machine, but it doesn't execute commands on remote computers.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Invoke-Command
Invoke-Command is the correct cmdlet because it is designed to execute PowerShell commands or script blocks on one or more remote computers and return the results to the local session. This allows the technician to run the IP configuration retrieval script against all domain computers from the management workstation and then pipe the output to Export-Csv.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
CompTIA often tests the distinction between interactive remote sessions (Enter-PSSession) and one-off command execution (Invoke-Command), leading candidates to choose Enter-PSSession when the requirement is to run a script against multiple computers and capture output.

Detailed technical explanation
How to think about this question
Under the hood, Invoke-Command uses WinRM (Windows Remote Management) to establish a session and run the script block on the target machine, serializing results back as deserialized objects. A subtle behavior is that by default, Invoke-Command runs commands in a disconnected session context, so any modules or variables not explicitly passed via the -ArgumentList parameter are unavailable on the remote machine. In real-world scenarios, technicians often combine Invoke-Command with a computer list from Active Directory and use -AsJob for parallel execution across many machines.

Real-world example
How this comes up in practice
A practitioner preparing for the 220-1202 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
