Question 4 5 pts
This question has two parts
1) (2 pts) Write the single Powershell statement using Get-ADUser that will retrieve references to all the user accounts on the currently logged-on system and store them into a variable called $accounts.
2) (3 pts) Give 2 Powershell commands for showing just the SAMAccountName information for all the accounts that are referenced in the $accounts variable (see first part of this question), one without using piping and one using piping.

Question 6 14 pts
This question has 3 parts.
Assume we have a DN hierarchy structure that looks like the following: DC=Net
DC=OurCourse OU=Area1
OU=Accounts OU=Staff
OU=Students OU=Area2
OU=Accounts OU=Faculty OU=Staff OU=Students
NOTE: There could be other account categories (OUs) besides Students, Faculty, and Staff, as well.

4/15/2018 Quiz: Test3 – Canvas – CSU
Accounts are created within the respective OUs, and each account’s CN (Common Name) and SAMAccountName all have the same value. Some sample DNs are listed here:
CN=SmitD,OU=Faculty,OU=Accounts,OU=Area2,DC=OurCourse,DC=Net CN=SmitC,OU=Faculty,OU=Accounts,OU=Area2,DC=OurCourse,DC=Net CN=SmitS,OU=Staff,OU=Accounts,OU=Area1,DC=OurCourse,DC=Net CN=SmitH,OU=Students,OU=Accounts,OU=Area1,DC=OurCourse,DC=Net CN=BrowSa,OU=Students,OU=Accounts,OU=Area1,DC=OurCourse,DC=Net
1) (5 pts) Write the Powershell command-line that will use Get-ADUser to retrieve all the students and store references to them into a variable called $studentsAll. (Remember that the Filter for Get-ADUser is “brain dead” when it comes to filtering on DistinguishedName with wildcards, so you have to pipe the output of Get-ADUser to Where-Object and phrase the DN “filter” with wildcards there instead.)
2) (4 pts) Write the Powershell command-line that will use Get-ADUser to retrieve all the students in Area2 and store references to them into a variable called $studentsArea2. (Remember that the Filter for Get-ADUser is “brain dead” when it comes to filtering on DistinguishedName with wildcards, so you have to pipe the output of Get-ADUser to Where-Object and phrase the DN “filter” with wildcards there instead.)
3) (5 pts) Assume that references to all the users (no matter what category) are in a variable called $usersAll. Write the Powershell command-line that will pipe the information in $usersAll to the Where-Object command to get just the users who are not students, and store these into a variable called $usersNotStudents.

Question 7 9 pts
This question has 3 parts.
Assume that we have VMware virtual machines and can access their snapshots via the
Get-Snapshot VMware/Powershell PowerCLI cmdlet. The syntax for using this cmdlet is: Get-Snapshot [[-Name] ] [-Id ] [-VM]
[-Server ] []
This can be used to retrieve any snapshots that exist on the VMware VCenter Server system.
New-Snapshot is also available, and it can be used for creating snapshots:
New-Snapshot [-VM] [-Name] [-Description ] [- Memory] [-Quiesce] [-Server ] [-RunAsync] [-WhatIf] [-Confirm] []
1) (3 pts) Write the line of code that will get the snapshot(s) for the VM referenced in the $vm variable on the currently-connected default VIServer and store any resulting references into a variable called $snapshots. (You can force $snapshots to be an array even if there is only a single item in it, if you enclose the call to Get-Snapshot inside the @() operator – put the Get-Snapshot cmdlet and any parameters inside the parentheses.)
2) (1 pts) Assume that the variable $snapshots is an array of references to VMware snapshots. Write the single line of Powershell code that will tell us how many snapshots

there are in the $snapshots array variable.
3) (5 pts) Assume you want to create snapshots for all the VMs that are referenced in the variable $vms. In a nicely-formatted / readable manner (multiple lines, appropriate indenting), write the code that would take each VM in $vms, pipe it to a ForEach-Object block, and, in this block create a snapshot called “Test3-Snapshot” and send the reference to the VM to the output stream. Do all this asynchronously, quiescing memory in the process.
