IP Address Allocation and Assignment

Correct Answer: Configure DHCP relay on LAN1 interface

The best answer is to 'Configure DHCP relay on LAN1 interface'. The DHCP relay agent data option in a DHCP service configuration is used to aid a DHCP client address request to be forwarded across networks. Setting up a DHCP relay will enable the DHCP server on LAN2 to assign correct IP addresses to clients on LAN1. The other solutions are not ideal for addressing the situation. 'Configure static IP on the client' is not a reliable permanent fix because it would involve manual work for each device on the network and if a device joined the network, it would not automatically receive an IP. 'Create another DHCP server on LAN1' could lead to further issues like IP address conflicts and unnecessary network overhead. Lastly, 'Combine LAN1 and LAN2 into the same subnet' would mean a major changes to network architecture that may not be required or feasible.

Correct Answer: Create an exclusion range for 192.168.29.10-200

The correct action in this scenario is to 'Create an exclusion range for 192.168.29.10-200'. By creating an exclusion range, the network administrator would reserve a set of IP addresses specifically for the company Wi-Fi network, ensuring that they are not allocated to other devices on the network by the DHCP server. 'Increasing the DHCP pool range' would not necessarily ensure the specific IP addresses are available for the Wi-Fi network. 'Decreasing the DHCP pool range' could limit the number of devices that can be connected to the network, which is not ideal. 'Creating reservations for all devices' is impractical, especially for a large network, because it requires manually assigning an IP address for each device.

Correct Answer: Switch to IPv6

The best solution when facing exhaustion of private IPv4 address space due to rapid expansion is to switch to IPv6. IPv6 provides a far greater number of available addresses compared to IPv4, solving the problem of running out of address space. Changing DHCP lease time wouldn't solve the problem of not having enough addresses to assign in the first place. Subnetting the current IPv4 network can momentarily alleviate the problem by using the address space more efficiently, but it's a more complex procedure and still doesn't provide nearly as many addresses as switching to IPv6. Lastly, using only static IP addresses would actually exacerbate the problem, as static IP addresses remain assigned to devices even when they're not in use, reducing the availability of addresses even further.
