Objective 1 - Network Infrastructure Design
Attached is a Visio network design that accommodates the following requirements:
​
-20 users in a Finance Department
-20 users in a Operations Department
-8 users in a Sales Department
-8 users in a Management Department
-200 users in a Call Floor Department
Objective 2 - Network Implementation

Above is a packet tracer configuration of a network implementation based off the following requirements:
-20 Users in the engineering department
-50 users in the manufacturing department
-30 users in the administration department
-Servers required: HTTP server, FTP server, SYSLOG server, and a DNS server
​
The network is segmented with 4 VLANs based on which section of the network; Server Farm, Engineering, Manufacturing, and Administration. The network uses a /20 subnet.
Objective 3 - Network Systems & Services
Attached is a PowerPoint showing the installation and configuration of different network systems and services across Windows servers. The environment consists of two domain controllers connected through a VPN tunnel, DNS, DHCP, Active Directory, WSUS, and NFS. There are also user templates for different types of users, allowing easier creation of new users.
Objective 6 - Virtualization & Mobile System Services

Above is a previously shown network diagram. Instead of having multiple servers dedicated to one task, all of the servers would be condensed into one virtual server. The virtual server will have a HTTP service, FTP service, SYSLOG service, a DNS service, and an additional host to gateway VPN service for accessing the company network remotely in a secure fashion. For mobile connectivity, I would place wireless access points throughout the network in each department, add another IP pool, and a VLAN for the wireless access.
