.SYNOPSIS
 This script restores active directory OU's and reconfigures SQL server.
.DESCRIPTION
A. Create a PowerShell script named “restore.ps1” within the “Requirements2” folder.
 For the first line, create a comment and include your first and last name along with your student ID.
Note: The remainder of this task shall be completed within the same script file, “restore.ps1.”
B. Write a single script within the “restore.ps1” file that performs all of the following functions without
user interaction:
1. Create an Active Directory organizational unit (OU) named “finance.”
2. Import the financePersonnel.csv file (found in the “Requirements2” directory) into your Active
Directory domain
 and directly into the finance OU. Be sure to include the following properties:
 • First Name
 • Last Name
 • Display Name (First Name + Last Name, including a space between)
 • Postal Code
 • Office Phone
 • Mobile Phone
3. Create a new database on the UCERTIFY3 SQL server instance called “ClientDB.”
4. Create a new table and name it “Client_A_Contacts.” Add this table to your new database.
5. Insert the data from the attached “NewClientData.csv” file (found in the “Requirements2” folder)
into the table created in part B4.
C. Apply exception handling using try-catch for System.OutOfMemoryException.
D. Run the script within the uCertify environment. After the script executes successfully,
 run the following cmdlets individually from within your Requirements2 directory:
1. Get-ADUser -Filter * -SearchBase “ou=finance,dc=ucertify,dc=com” -Properties
DisplayName,PostalCode,OfficePhone,MobilePhone > .\AdResults.txt
2. Invoke-Sqlcmd -Database ClientDB –ServerInstance .\UCERTIFY3 -Query ‘SELECT * FROM
dbo.Client_A_Contacts’ > .\SqlResults.txt
Note: Ensure you have all of the following files intact within the “Requirements2” folder, including the
original files:
 • “restore.ps1”
 • “AdResults.txt”
 • “SqlResults.txt”
