This flow shows how Enter-PSSession starts an interactive remote session, lets you run commands remotely, then exit back to local.

Execution Sample

PowerShell

Enter-PSSession -ComputerName Server01
Get-Process
Exit-PSSession

Starts a remote session to Server01, runs Get-Process remotely, then exits back to local shell.

Execution Table

Step	Action	Evaluation	Result
1	Run Enter-PSSession -ComputerName Server01	Connects to Server01	Interactive remote session started
2	Run Get-Process	Executes on Server01	Lists processes running on Server01

Key Moments - 3 Insights

Why does the prompt change after running Enter-PSSession?

Because Enter-PSSession opens an interactive remote session, the prompt changes to show you are connected to the remote computer (see execution_table step 1).

Are commands run after Enter-PSSession executed locally or remotely?

Commands run after Enter-PSSession are executed on the remote computer until you exit the session (see execution_table step 2).

How do you return to your local PowerShell prompt?

You run Exit-PSSession to end the remote session and return to local (see execution_table step 3).

Full Transcript

Enter-PSSession is a PowerShell command that lets you connect to another computer and run commands there as if you were sitting at that computer. When you run Enter-PSSession with a computer name, PowerShell opens a remote session and changes the prompt to show you are connected remotely. Any commands you type now run on that remote computer. When you are done, you type Exit-PSSession to close the remote connection and return to your local PowerShell prompt. This lets you manage remote computers easily and interactively.

Practice

1. What is the main purpose of the Enter-PSSession cmdlet in PowerShell?

easy

A. To create a new local PowerShell script

B. To copy files between computers

C. To list all running processes on the local computer

D. To start an interactive session on a remote computer

Solution

1. Step 1: Understand the cmdlet purpose

   Enter-PSSession is designed to open a remote interactive session on another computer.

2. Step 2: Compare options

   Only To start an interactive session on a remote computer describes starting an interactive remote session, which matches the cmdlet's purpose.

3. Final Answer:

   To start an interactive session on a remote computer -> Option D

4. Quick Check:

   Enter-PSSession = start remote interactive session [OK]

Hint: Remember: Enter-PSSession = remote interactive session [OK]

Common Mistakes:

• Confusing Enter-PSSession with file copy commands
• Thinking it runs commands locally only
• Assuming it creates scripts

2. Which of the following is the correct syntax to start a remote session on a computer named 'Server01' using Enter-PSSession?

easy

A. Enter-PSSession -ComputerName Server01

B. Enter-PSSession Server01 -ComputerName

C. Enter-PSSession -Name Server01

D. Enter-PSSession -Session Server01

Solution

1. Step 1: Recall correct parameter usage

   The correct parameter to specify the remote computer is -ComputerName.

2. Step 2: Match syntax

   Enter-PSSession -ComputerName Server01 uses Enter-PSSession -ComputerName Server01, which is the correct syntax.

3. Final Answer:

   Enter-PSSession -ComputerName Server01 -> Option A

4. Quick Check:

   Correct parameter for remote computer = -ComputerName [OK]

Hint: Use -ComputerName to specify remote computer [OK]

Common Mistakes:

• Using wrong parameter names like -Name or -Session
• Placing parameters in wrong order
• Omitting the -ComputerName parameter

3. What will be the output of the following commands?

Enter-PSSession -ComputerName Server01
Get-Process
Exit-PSSession

medium

A. Lists processes running on Server01, then returns to local session

B. Lists processes running on local computer, then exits session

C. Throws an error because Get-Process is invalid remotely

D. Starts a new local PowerShell window

Solution

1. Step 1: Understand Enter-PSSession effect

   The command opens a remote session on Server01, so subsequent commands run there.

2. Step 2: Analyze commands inside session

   Get-Process runs on Server01, listing its processes. Exit-PSSession ends the remote session and returns to local.

3. Final Answer:

   Lists processes running on Server01, then returns to local session -> Option A

4. Quick Check:

   Commands run remotely inside Enter-PSSession = Lists processes running on Server01, then returns to local session [OK]

Hint: Commands after Enter-PSSession run remotely until exit [OK]

Common Mistakes:

• Assuming commands run locally after Enter-PSSession
• Thinking Get-Process is invalid remotely
• Confusing Exit-PSSession with closing PowerShell

4. You run Enter-PSSession -ComputerName Server01 but get an error: "Access is denied." What is the most likely cause?

medium

A. You forgot to run PowerShell as administrator locally

B. You do not have permission to access Server01 remotely

C. PowerShell is not installed on Server01

D. The Server01 computer name is misspelled

Solution

1. Step 1: Understand "Access is denied" meaning

   This error usually means your user account lacks permission to connect remotely.

2. Step 2: Evaluate other options

   Misspelling would cause "computer not found" error, not access denied. PowerShell missing would cause different error. Running as admin locally is not always required.

3. Final Answer:

   You do not have permission to access Server01 remotely -> Option B

4. Quick Check:

   Access denied = permission issue [OK]

Hint: Access denied means permission problem on remote computer [OK]

Common Mistakes:

• Assuming computer name typo causes access denied
• Thinking local admin rights fix remote permission
• Ignoring remote user permissions

5. You want to run a command on multiple remote computers named Server01 and Server02 using Enter-PSSession. Which approach is best to automate this?

hard

A. Use Enter-PSSession with -ComputerName Server01; then run Enter-PSSession again for Server02 without exiting first

B. Run Enter-PSSession once with both computer names separated by comma

C. Use a loop to run Enter-PSSession for each computer, then run commands inside each session

D. Run Enter-PSSession on Server01, then copy commands manually to Server02

Solution

1. Step 1: Understand Enter-PSSession scope

   Enter-PSSession opens one interactive session at a time; it does not accept multiple computers simultaneously.

2. Step 2: Automate multiple sessions

   Using a loop to open a session for each computer, run commands, then exit is the best way to automate multiple remote sessions.

3. Final Answer:

   Use a loop to run Enter-PSSession for each computer, then run commands inside each session -> Option C

4. Quick Check:

   Enter-PSSession handles one computer at a time; loop to automate [OK]

Hint: Enter-PSSession is single computer; loop for multiples [OK]

Common Mistakes:

• Trying to enter multiple sessions at once
• Not exiting session before starting another
• Manually copying commands instead of automating
