What should you recommend?

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.

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.
