1. Install and configure a DHCP server

Dynamic Host Configuration Protocol (DHCP) is a client/server protocol that automatically provides an Internet Protocol (IP) client device (client, smartphone, etc.) with its IP address and other related configuration information such as the subnet mask and default gateway. DHCP allows client devices to obtain necessary TCP/IP configuration information from a DHCP server.

• Sign in as w99-admin and complete all remaining work using this account.  

• On W99 SERVER1 add the DHCP role using ‘Server Manager’. 

• Complete the post-deployment configuration by clicking on the ‘Notifications’ icon (yellow triangle with exclamation mark) of the ‘Server Manager’ and select ‘Complete DHCP configuration’ in the ‘Notifications’ area of the ‘Server Manager’. 

• Use the default settings to complete the DHCP setup. 

• Click again on the ‘Notifications’ icon to list the messages. 

a) Take a screenshot of the two notification messages. The screenshot must also show the VM title bar. Insert the screenshot below this line.

• On W99 SERVER1 open the DHCP management console (found with the ‘Administrative Tools’ on the server).

• Create a new DHCP scope:

  o Select ‘IPv4’ and invoke the ‘New Scope Wizard’.

  o In the ‘New Scope Wizard’ specify only the values listed below, keep all other default settings: 

• Make sure to activate the scope if it is not active.  

• Open a PowerShell prompt and issue the command set (all on one line):

Get-Date; whoami ; Get-DHCPServerv4Scope 


b) Take a screenshot of the PowerShell window showing the output of the last command set. Insert the screenshot below this line.

On W99-CLIENT1:

• Start W99-CLIENT1 if it is not already running. 

• Change the W99-CLIENT1 IPv4 settings to obtain IP and DNS settings automatically.

• Confirm that W99-CLIENT1 has received its IPv4 settings from W99-SERVER1. Resolve any issues that may prevent this from occurring.

• Open a PowerShell prompt, and type the command:   ipconfig /all

c) Take a screenshot of the PowerShell window. Insert the screenshot below this line. 


2. Server Backup 

In this exercise W99-SERVER3 will be backed up then recovered using the previously taken backup. W99-CLIENT1 will provide the backup store. To recover the server using a network share a functional DHCP service must be available on the network. The required DHCP service will be provided by W99-SERVER1 and this VM must therefore be running. 

On W99-CLIENT1:

W99-CLIENT1 must use the IPv4 address from Assessment 2 (10.19.99.201) and Network Discovery must be enabled. If necessary, change the IPv4 address to 10.19.99.201 / 24. 

• On the new volume create the folder ‘Z:Server-Backup’.

• Open the ‘Properties’ of ‘Z:Server-Backup’, select ‘Sharing’ and click on ‘Advanced Sharing…’.

• Select ‘Share this folder’, click on ‘Permissions’, in the ‘Allow’ column assign ‘Full Control’ for the ‘Everyone’ group and click OK to close all properties windows.

• Confirm that W99-CLIENT1 can successfully ping W99-SERVER3, resolve any communication issues if required.

On W99-SERVER3:

W99-SERVER3 must use the IPv4 address from Assessment 2 (10.19.99.3) and ‘Network Discovery’ must be enabled. If necessary, change the IPv4 address to 10.19.99.3 / 24.

If any of the following four steps does not work, you will have to go back and resolve the issue before proceeding to the next step

• Confirm that W99-SERVER3 can successfully ping W99-CLIENT1, resolve any communication issues if required

• Open Windows Explorer and in the left pane click on ‘Network’. If prompted, turn on ‘Network Discovery’ and use the setting ‘No, make the network that I am connected to a private network’.

• You should now see W99-CLIENT1 in the list of computers. Double-click on W99-CLIENT1 and select the ‘Server-Backup’ share. 

• If prompted for credentials provide the administrator account and password for W99-CLIENT1

• To confirm that you can write to the network folder, open Notepad, write one or two words and save the file as W99-testfile.txt in this folder.

In order to run backups, the ‘Windows Server Backup’ feature must first be installed. 

• Using ‘Add roles and features’ add the ‘Windows Server Backup’ feature on W99-SERVER3.

Running a backup is a disk intensive task. You are to monitor the disk activity while running a backup on W99-SERVER3.   

• Open ‘Task Manager’ and switch to the ‘More details’ view

• Select the ‘Performance’ tab and click on ‘Open Resource Monitor’

• In the ‘Resource Monitor’ select the ‘Disk’ tab

You are now ready to take a backup of W99-SERVER3

• Start the ‘Windows Server Backup’ tool 

• Once the backup has started, switch the focus to the ‘Resources Monitor’ and observe the ‘Disk 0 (C:) Queue length’

a) Take a screenshot of the queue length value while the backup is running (the screenshot must also show the VM title bar commands). Insert the screenshot below this line. 

• Close the ‘Windows Server Backup’ tool once the backup has successfully completed and close the ‘Resource Monitor’ and ‘Task Manager’. 

• Rename the server to W99-SERVER333

On W99-CLIENT1:

• Open a PowerShell prompt, and change to the Z:Server-Backup folder by typing the commands:

Z:

CD Z:Server-Backup

• Then issue the following commands sequence (executing the commands separately is not acceptable): 

Dir ; whoami ; Get-Volume | ft ; dir WindowsImageBackupW99-SERVER3

b) Take a screenshot of the PowerShell window (the screenshot must also show all commands). Insert the screenshot below this line.

• In the PowerShell window issue the command sequence (executing the commands separately is not acceptable: 

Netsh advfirewall show all state ; ping W99-SERVER333 ; Get-Date

Resolve any communication issues if the ping command is not successful before providing the required screenshot. 

c) Take a screenshot showing the output of the commands (the screenshot must the VM title bar and the output of the above command set). Insert the screenshot below this line.


3. Server Recovery

In this exercise the Windows 2016 recovery process will be used to restore the server from a network backup to its original configuration. 

On W99-SERVER333:

• Restart the server into the advanced boot options by issuing the command: 

Shutdown /r /o

• Under ‘Choose an options’ select ‘Troubleshoot’. 

• In the ‘Advanced options’ select ‘System Image Recovery’ to invoke the recovery process.

• After the reboot specify w99-admin as the account to continue with and provided the required password.

• Select ‘Cancel’ when the message will pop up informing you that no system image was found on the computer to continue with the ‘Re-image your computer’ wizard.

• Click ‘Next’ to get to the ‘Select the location of the backup …’ screen.

• Click on ‘Advanced’, select ‘Search for a system image on the network’ and confirm with ‘Yes’ that this is what you want to do.

• Specify the location of the system image: W99-CLIENT1Server-Backup

Note that this will only work if ‘Network Discovery’ is enabled on the target system

• When entering the credentials use the following format:

User name: W99-CLIENT1Administrator 

Password: <provide the password for the above account>

• The backup that you previously should now be listed.

• Select this backup and click on ‘Next’.

• If the entry listed in the ‘Select the date and time of the system image to restore’ screen is correct, select it and click on ‘Next’.

Note that the time stamp is listed in GMT-8:00 and would therefore need to be converted to GMT+10 (+Daylight Saving) to match the corresponding Australian time. 

• On the ‘Choose additional restore options’ click ‘Next’ to get to the final screen. 

a) Before clicking on ‘Finish’, take a screenshot showing the final screen of the ‘Re-image your computer’ wizard (the screenshot must the VM title bar). Insert the screenshot below this line.

• To initiate the restore process click ‘Finish’ followed by ‘Yes’ when the warning pops up that all data on the drives to be restored will be replaced.

• Take a note of the time when the system initiates the automatic restart. You will use this time to find the corresponding events in the EventLog. 

• Sign in as w99-admin after the system has rebooted and open ‘Event Viewer’.

• Under ‘Windows Logs’ select the ‘System’ log.

• By default, events are ordered by time. The first event when the system boots is generated by the ‘EventLog’ source. Scroll down to the first entry after the restore and select the 1st EventLog entry. You will notice that there is a time gap to the previous entry that corresponds to the time difference between the time the backup was taken and the time when the system was restored. 

• Make sure that in ‘Filter Current Log…’ no filtering is enabled (all events must be displayed).  

• Select the 1st EventLog entry that follows the last entry of the time of the backup.  

b) Take a screenshot showing the last backup event and the first restore event (the screenshot must also show the VM title bar). Insert the screenshot below this line.

• W99-SERVER1 and W99-CLIENT1 are not required for the remaining tasks of this assessment an may be shut down. 


4. Adding disks to the server

RAID allows storing of data across multiple disks. The RAID level of a storage system determines its performance characteristics and its ability to protect data against a storage component failure. Choosing an appropriate storage environment is critical when designing and deploying a server. 

As first step you have to use VirtualBox to add new disk resources (storage) to W99 SERVER3. In VirtualBox the VM cannot be running when adding disks. 

• Shut down W99-SERVER3 and add three virtual disks to the W99-Win2016-Full-3-DE-Eval VM:

o Each disk is to be dynamically allocated and 10GB in size

o The virtual disk files are to be located in your work area in the same folder that is holding the first disk of W99-SERVER3:

The example below shows the location and file names to be used for the disks:

C:Users<your local account>W99-SERVER3W99-SERVER3-Disk1.vdi

C:Users<your local account>W99-SERVER3W99-SERVER3-Disk2.vdi

C:Users<your local account>W99-SERVER3W99-SERVER3-Disk3.vdi

Make sure you replace the highlighted values with your own settings when creating the VM disks. 

a) Provide a screenshot of the VirtualBox ‘Global Tools’ showing the ‘Hard disk’ tab. Insert the screenshot below this line.

• Start the W99-Win2016-Full-3-DE-Eval VM and sign in as w99-admin.

• Open ‘Disk Management’ in ‘Computer Management. 

• Accept the defaults when prompted to initialize the disks for writing a signature to the new disks

• The original disk containing the OS will be shown as ‘Disk 0’; the 3 new disks will be shown as ‘Disk 1’, ‘Disk 2’ and ‘Disk 3’. 

• Convert the 3 new ‘Basic’ disks to ‘Dynamic disks’ (do not change ‘Disk 0’). 


5. RAID0

Perform the following:

• Open ‘Disk Management’ in ‘Computer Management’.
