Answer:

FF-FF-FF-FF-FF-FF and 255.255.255.255

Explanation:

FF-FF-FF-FF-FF-FF can be defined as the layer 2 address broadcast which is often used on ethernet frames as well as help to broadcast all equipment due to the fact broadcast is made possible through Ethernet networks in which the Frames are addressed to reach every computer system on a given LAN segment as far as they are addressed to MAC address FF:FF:FF:FF:FF:FF.

255.255. 255.255 can be seen as the layer 3 address which help to address the exact same hosts because it enables the broadcast address of the zero network which is the local network due to the fact that the IP broadcasts are often used by BOOTP and DHCP clients to find and send requests to their respective servers in which a message sent to a broadcast address may be received by all network-attached hosts.

Therefore the Layer 2 and Layer 3 destination addresses which the message contain are FF-FF-FF-FF-FF-FF and 255.255.255.255

Use the System Restore tool to restore the affected computers back to a point before the problematic updates. To forestall issues with problematic updates, one needs to install and configure the Windows Server Update Services (WSUS) Server role.

Explanation:

Windows Update creates a restore point prior to applying any updates and this makes it easier to rollback any problematic updates using the aptly named System Restore utility.  System Restore can be launched either from within Windows or during startup depending on whether the computer can be booted  or not.

One solution to preventing this kind of problem is the implementation of a Windows Server role, the Windows Server Update Services (WSUS), which helps administrators to safely manage Windows Update for clients within its network. WSUS allows administrators to test updates for issues and approve them before they are available for deployment to clients.
