An administrator has both Avaya and Cisco VoIP phones that require the same DHCP option. What can the administrator do with these two different models of phones?
A.
Only one type of device can be online at any given time
B.
Both device types can be online at the same time, but they must be on different subnets
C.
Both device types can be on the same range through the use of separate Option Filters
D.
The administrator must contact the vendors to update the devices to use different DHCP options
Comprehensive and Detailed In-Depth Explanation:NIOS supports advanced DHCP configuration, including Option Filters, which match client requests based on DHCP options (e.g., Option 60 for Vendor Class Identifier). If Avaya and Cisco VoIP phones require the same DHCP option (e.g., Option 66 for TFTP server), the administrator can use separate Option Filters to distinguish the devices by their unique identifiers (like Vendor Class IDs: "Avaya" vs. "Cisco") and assign them IPs from the same range with the shared option. This allows both device types to coexist on the same subnet and range, eliminating the need for segregation (Option B) or vendor intervention (Option D). Option A is overly restrictive and incorrect. This is a practical DHCP troubleshooting scenario in the INE course.References:Infoblox NIOS Administrator Guide – DHCP Option Filters; INE Course Content: NIOS DDI DHCP Troubleshooting.
