Introduction
You are required to design and build an internet-connected secure server network for Smith Logistics, which is a medium-sized warehouse and logistics company.
2.2 Scenario
A recent minor outage has alerted senior management to the importance of the company’s IT system to day-to-day operations and has given more weight to your company’s recommendation for upgrading.

Currently, the existing network infrastructure has been shoe-horned onto an ageing server which is running Windows 2003 Small Business Server with clients as old as Windows XP and some as new as Windows 10.

The company acknowledges that, given recent network and computer system
breaches such as Wanna Cry, that they need to update their IT infrastructure and are looking to create a more secure IT infrastructure with room for expansion.
Due to the current company data governance framework, the company has no plan to move to a cloud solution yet, apart from the email service, such as Office 365. Therefore, the current plan is to upgrade their existing network to a fault tolerant server network, which can spread existing workloads across multiple servers. You will also need to build Windows 10 clients which you can
join to the domain to use to help document that all the services are working correctly.

The required workloads across the servers are:
 Internally facing
 Active Directory Domain Services
 DNS
 DHCP
 Internal File Sharing Services
 Externally facing
 Web Server – Apache, PHP and MySQL

The company has limited budget for this upgrade. Therefore, you have to consider how many servers and which operating systems are required, in order to achieve such requirement.

Smith Logistics has emphasised that they want to take this opportunity to strengthen their network security and are looking for you to explain what security considerations and/or improvements you
can make as you outline the solution.
Smith Logistics store a lot of information and data, and they want to ensure that their servers, in particular, their file server has the appropriate disk redundancy in place so that they can tolerate
disk failures without having to depend upon a backup solution.

They also acknowledge that given they are rebuilding their entire server infrastructure they will also need to revisit backup options and
have therefore asked you for advice both on disk redundancy and backup solutions.
