According to the exhibit, the DHCP server scope for the FortiLink interface has a vci-string setting

with the value “Cisco AP c2700”. This setting is used to match the vendor class identifier (VCI) of the

DHCP clients that request an IP address from the DHCP server. The VCI is a text string that uniquely

identifies a type of vendor device. Therefore, option C is true because the vci-string setting restricts

the IP address assignment to FortiSwitch and FortiExtender devices, which use the VCI “Cisco AP

c2700”. Option A is false because the vci-string setting does not ignore DHCP requests coming from

FortiSwitch and FortiExtender devices, but rather accepts them. Option B is false because the vci-

string setting does not reserve IP addresses for FortiSwitch and FortiExtender devices, but rather

assigns them dynamically. Option D is false because the vci-string setting does not restrict the IP

address assignment to devices that have FortiSwitch or FortiExtender as their hostname, but rather

to devices that have “Cisco AP c2700” as their VCI.
