C:\Users\[USERNAME]\AppData\Local\Packages\Microsoft.Windows.ContentDeliveryManager\LocalState\Asset is the correct answer... given 100 characters to work with. Since the backgrounds are downloaded, stored and overwritten.. they are stored here.
C:\ProgramData\Microsoft\Windows\SystemData is where the lock screen can be changed or overwritten, given permission.
C:\Windows\Web\Screen is the location of the windows prelogin screen background.
And C:\Windows\Web\Wallpaper is where default windows 7 wallpapers for your desktop are saved.

In a cluster, what VMware vSphere feature allows a virtual machine to run a replica of itself on a different host to allow for seamless fail-over in case of host failure?

In a cluster, what VMware vSphere feature allows a virtual machine to run a replica of itself on a different host to allow for seamless fail-over in case of host failure?

• Distributed Resource Scheduler
• Fault Tolerance
• High Availability
• vMotion 

 

EXPLANATION

With Fault Tolerance, a replica VM is created on a different host in the cluster to work in sync with the primary virtual machine on which Fault Tolerance is enabled. When host failure is detected,
the replica VM takes place of the primary virtual machine with no downtime. This differs from High Availability in that the virtual machine is typically restarted on to another host, requiring downtime.

• last /etc/users

EXPLANATION

The "tail" command outputs the last 10 lines of the file that it is passed.
