You work as the security administrator at Certpaper.com. You must ensure that internal access to
other parts of the network is controlled and restricted. The solution which you implement to restrict
network access must be hardware based. You also want to use the least amount of administrative
effort to accomplish your task.
How will you accomplish the task?

A.
Deploy a VPN (Virtual Private Network).

B.
Deploy a VLAN (Virtual Local Area Network) Deploy.

C.
Deploy a proxy server Deploy.

D.
Deploy firewalls between your subnets.

Explanation:

Implement a VLAN (Virtual Local Area Network) to restrict network access is the best answer.
VLAN’s would restrict access only to their local VLAN, and this would require less administrative
overhead than setting up firewalls at each subnet. They are also hardware based (at the switch
and MAC level) Firewalls are used so that external users (outside the organization cannot get in),
whereas VLAN’s are used within an organization to provide security.
