HOTSPOT
You have a server named Server1. Server1 runs Windows Server 2012 R2 and has the Windows
Deployment Services (WDS) server role installed.
You install the DHCP Server server role on Server1.
You need to ensure that Server1 can respond to DHCP clients and WDS clients.
What should you configure for the DHCP service and the WDS service?
To answer, configure the appropriate options in the answer area.
Answer: See the explanation
Explanation:
Enable Option 60 PXEClient
Enable the Do not listen on DHCP ports optionTraditionally, only DHCP listened on port UDP 67, but now WDS also listens on port UDP 67 WDS and
DHCP are installed on the same server: You must tell WDS not to listen on port UDP 67, leaving it
available for DHCP traffic only. But then how does the client find the WDS server? You set option 60
in DHCP.
The DHCP option 60, when set to “PXEClient” is used only to instruct the PXE clients to try to use a
PXE Service bound on UDP port 4011. Actually, if there is a bootp or dhcp service bound on UDP port
67 of a host (usually called a server), a PXE service cannot bind on that port on that host. Since the
PXE Service uses BOOTP/DHCP packets to send the options 66 and 67 to the clients, it needs to be
able to bind to the associated port (bootps) or to an alternated port (4011) that the clients know
they must use as the alternate port. And to instruct the clients to use this alternate port, you have to
set dhcp option 60 to “PXEClient”.
If Windows Deployment Services and DHCP are running on the same computer, configuring
Windows Deployment Services to not respond to any client computers will not work. This is because
although Windows Deployment Services will not respond, DHCP will. You should disable WDS if you
have both installed and using DHCP.
To configure Windows Deployment Services to run on the same computer as Microsoft DHCP
Right-click the server and click Properties. On the DHCP tab, select Do not listen on port 67 and
Configure DHCP Option #60 Tag to PXEClient.
This procedure does the following: Sets
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WDSServer\Parameters
\UseDhcpPorts to 0.
Adds the option 60 PXEClient tag to all of your DHCP scopes.
