Your company is growing dramatically via acquisitions of other companies. As the network
administrator, you need to keep up with the changes because they affect the workstations,
and you need to support them. When you started, there were 15 locations connected via
routers, and now there are 25. As new companies are acquired, they are migrated to Win-
dows Server 2012 R2 and brought into the same domain as another site. Management says
that they are going to acquire at least 10 more companies in the next two years. The engi-
neers have also told you that they are redesigning the company's Class B address into an IP
addressing scheme that will support these requirements and that there will never be more
than 1,000 network devices on any subnet. What is the appropriate subnet mask to support
this network when the changes are completed?
A.
255.255.252.0
B.
255.255.248.0
C.
255.255.255.0
D.
255.255.255.128

You work for a small printing company that has 75 workstations. Most of them run stan-
dard office applications such as word processing, spreadsheet, and accounting programs.
Fifteen of the workstations are constantly processing huge graphics files and then sending
print jobs to industrial-sized laser printers. The performance of the network has always been
an issue, but you have never addressed it. You have now migrated your network to Windows
8 and Windows Server 2012 R2 and have decided to take advantage of the routing capability
built into Windows Server 2012 R2. You choose the appropriate server and place two NICs
in the machine, but you realize that you have only one network address, 201.102.34.0, which
you obtained years ago. How should you subnet this address to segment the bandwidth hogs
from the rest of the network while giving everyone access to the entire network?
A.
255.255.255.192
B.
255.255.255.224
C.
255.255.255.252
D.
255.255.255.240

You work for Carpathian Worldwide Enterprises, which has more than 50 administrative
and manufacturing locations around the world. The size of these organizations varies greatly,
with the number of computers per location ranging from 15 to slightly fewer than 1,000.
The sales operations use more than 1,000 facilities, each of which contains 2 to 5 computers.
Carpathian is also in merger talks with another large organization. If the merger materializes
as planned, you will have to accommodate another 100 manufacturing and administrative
locations, each with a maximum of 600 computers, as well as 2,000 additional sales facilities.
You don't have any numbers for the future growth of the company, but you are told to keep
growth in mind. You decide to implement a private addressing plan for the entire organiza-
tion. More than half of your routers don't support variable-length subnet masking. Which
subnet masks would work for this situation? (Choose all that apply.)
A.
255.255.224.0
