Your network contains two servers named Server1 andServer2 that run Windows Server 2012. Server1 is a
DHCP server that is configured to have a scope named Scope1. Server2 is configured to obtain an IP address
automatically.
In Scope1, you create a reservation named Res_Server2 for Server2.
A technician replaces the network adapter on Server2.
You need to ensure that Server2 can obtain the sameIP address.
What should you modify on Server1?

A.
The Advanced settings of Res_Server2

B.
The MAC address of Res Server2

C.
The Network Access Protection Settings of Scope1

D.
The Name Protection settings of Scope1

Explanation:
For clients that require a constant IP address, youcan either manually configure a static IP address,or assigna
reservation on the DHCP server.
Reservations are permanent lease assignments that are used to ensure that a specified client on a subnet
canalways use the same IP address.
You can use DHCP reservations for hosts that require a consistent IP address, but do not need to be
staticallyconfigured.
DHCP reservations provide a mechanism by which IP addresses may be permanently assigned to aspecific
client based on the MAC address of that client.
The MAC address of a Windows client can be found running the ipconfig /all command. For Linux systems
thecorresponding command is ifconfig -a. Once the MAC address has been identified, the reservation maybe
configured using either the DHCP consoleor at the command prompt using the netsh tool.
