You have configured a group policy preference that creates a VPN connection for all computers in the GPO's scope. One user says the connection was there yesterday, but it's no longer showing in his Network Connections window. You suspect he might have deleted the connection accidentally. What can you do to make sure the VPN connection is re$-$created even if a user deletes it$?$

a$.$ Disable the "Remove this item when it is no longer valid" option.

b$.$ Configure the Read$-$only option.

c$.$ Configure item$-$level targeting.

d$.$ Disable the "Apply once and do not reapply" option.
