Microsoft MCSE 070-980 : Recertification for MCSE: Server Infrastructure

070-980 Latest Exam Braindumps

Question 1: Your network contains a server named Server1 that runs Windows Server 2012. Server1 has
the DHCP Server server role installed. The network contains a Virtual Desktop Infrastructure (VDI).
All virtual machines run Windows 8.
You identify the following requirements for allocating IPv4 addresses to client computers:
All virtual desktops must have static IP addresses.
All laptop computers must receive dynamic IP addresses.
All virtual desktops must be prevented from obtaining dynamic address.
You need to recommend a DHCP solution that meets the requirements for allocating IPv4 addresses.
The solution must use the least amount of administrative effort.
What should you recommend?
More than one answer choice may achieve the goal. Select the BEST answer.
A. Configure DHCP filtering.
B. Configure DHCP policies.
C. Create two physical subnets. Connect the laptop computers to the subnet that contains Server1.
D. Create two physical subnets. Configure 802.1X authentication for each subnet.
Correct Answer: B
The DHCP Server role in Windows Server 2012 introduces a new feature that allows you to create
IPv4 policies that specify custom IP address and option assignments for DHCP clients based on a set
of conditions.
The policy based assignment (PBA) feature allows you to group DHCP clients by specific attributes
based on fields contained in the DHCP client request packet. PBA enables targeted administration
and greater control of the configuration parameters delivered to network devices with DHCP.
Example: In a subnet which has a mix of wired and mobile computers, you might want to assign a
shorter, 4 hour lease duration to mobile computers and longer, 4 day lease duration to wired
computers.
Incorrect:
not A: DHCP filtering provides security by filtering untrusted DHCP messages. An untrusted message
is a message that is received from outside the network or firewall, and that can cause traffic attacks
within network.
