Your company has a main office. The main office is located in a building that has 10 floors.
A datacenter on the ground floor contains a Windows Server 2012 failover cluster. The failover cluster contains a DHCP server resource named DHCP1. All client
computers receive their IP addresses from DHCP1. All client computers are part of the 131.107.0.0/16 IPv4 subnet.
You plan to implement changes to the network subnets to include a separate subnet for each floor of the office building. The subnets will connect by using routers.
You need to recommend changes to the DHCP infrastructure to ensure that all of the client computers can receive their IP configuration by using DHCP.
What should you recommend?
More than one answer choice may achieve the goal. Select the BEST answer.

A.
Install a remote access server on each floor. Configure a DHCP relay agent on each new DHCP server. Create a scope for each subnet on DHCP1.

B.
Install a DHCP server on each floor. Create a scope for the local subnet on each new DHCP server. Enable DHCP Failover on each new DHCP server.

C.
Configure each router to forward requests for IP addresses to DHCP1. Create a scope for each subnet on DHCP1.

D.
Configure each router to forward requests for IP addresses to DHCP1. Create a scope for the 10.0.0.0/16 subnet on DHCP1.

Explanation:
Excerpt: In TCP/IP networking, routers are used to interconnect hardware and software used on different physical network segments called subnets and forward IP
packets between each of the subnets. To support and use DHCP service across multiple subnets, routers connecting each subnet should comply with DHCP/
BOOTP relay agent capabilities described in RFC 1542.
