Your network contains a single Active Directory domain. All servers run Windows Server 2008 R2. You deploy a new server that runs Windows Server 2008 R2. The server is not connected to the internal network. You need to ensure that the new server is already joined to the domain when it first connects to the internal network. What should you do() ["From a domain controller, run sysprep.exe and specify the \/oobe parameter.

You have a file server named Server1 that runs Windows Server 2003 Service Pack (SP2). Server1 has a 10-gigabit network adapter and is connected to a 100-Mb switch. You replace the 100-Mb switch by using a 1-GB switch. You discover that copying files to Server1 over the network is slow. You need to reduce the amount of time it takes to copy files to Server1 over the network. Which connection type should you specify for the network adapter?
