Refer to the exhibit. After an engineer configured a new Cisco router as a DHCP server, users reported two primary issues:
• Devices in the HR subnet have intermittent connectivity problems.
• Workstations in the LEGAL subnet cannot obtain IP addresses.
Which configurations must the engineer apply to ROUTER_1 to restore connectivity for the affected devices?
The correct configuration must ensure that the IP helper addresses are set correctly for each VLAN interface to forward DHCP requests to the DHCP server, and that the IP addresses are excluded appropriately to avoid conflicts. Option D correctly configures the IP helper addresses for each VLAN and excludes a manageable range of IP addresses. It also accurately sets the DHCP pools for the HR and LEGAL subnets with the appropriate network ranges and default routers. This ensures both subnets can obtain IP addresses and have proper connectivity.
Difference between B and D relies on ip helper address. D its he only one that has the same ip helper addresses and properly excluded the address
D == 1. excludes IP consistently (not crazy amount are excluded) 2. uses correct consistent DHCP server IP with the "ip helper-address .."
D for spot the difference
