Scenario: A Citrix Administrator needs to set up a new provisioning environment. The
administrator builds and configures two Provisioning Servers to support 200 target devices. All of
the target devices are configured to start up using vDisks that are caching in device HD. Network
Engineering mandates that the administrator configure the TFTP service and DHCP scope to
assign IP addresses to all the target devices.
When the administrator tries to start any target devices, the machines hang and show the error in
the attached exhibit.
Refer to the Exhibit to view the error message.
Which action could the administrator take to resolve this issue?
A.
Enable DHCP options 66 and 67.
B.
Assign a vDisk to the target devices.
C.
Set the firewall to allow UDP 67 and 68.
D.
Configure the correct VLAN ID for the target devices.

This answer does not make sense…

I think it should be option D:

BOOTP/DHCP Codes
• PXE-E51: No DHCP or proxyDHCP offers were received. The client did not receive any valid DHCP, BOOTP or proxyDHCP offers. To resolve this issue, check each of the following network configuration items:
DHCP services are not available on the network to which the PXE-enabled NIC is connected.
A DHCP proxy or IP helper address is not configured for the subnet on which the PXE client is connected.
The switch port connected to the PXE NIC is running Spanning Tree Protocol, EtherChannel Protocol, or Port Aggregation Protocol and is thus not activated immediately when a link is detected. This forces the DHCP request from the PXE client to timeout.
DHCP is available on the network, but PXE is not.
The network cable is not attached to the PXE-enabled NIC on the target server.
