·   All the departments must be separated with unique subnet and should not communicate with each other unless there is a special requirement.

·   IPs should assign using DHCP.

·   ERP and CRM Systems need to be implemented in this in local servers.

·   Number of servers required for the Server room need to be Uses static IPs.

·   High level of redundancy is expected in network design to eliminate single point of failures and traffic bottle necks.

·   Sales and Marketing need to access Network resources using WIFI connectivity.

·   Proper methods for networking monitoring and troubleshooting need to be established.

·   All possible network security mechanisms should be implemented.

·     Prepare a written network design plan to meet the above mentioned user requirements including a blueprint drawn using a modeling tool. (Ex: EdrawMax).

ANSWER:

A subnet, or subnetwork, is a segmented piece of a larger network. Organizations will use a subnet to subdivide large networks into smaller. One goal of a subnet is to split a large network into a grouping of smaller, interconnected networks to help minimize traffic. By using DHCP protocol it automatically assign networks to the above departments.

The networks should be given the following subnet mask to make easy allocation of a certain department.

 

Customer Care 10 -subnet mask is 255.192.0.0

Sales and Marketing 20-subnet mask is 255.255.240.0

Finance 25-subnet mask is 255.255.255.128

Legal 5- subnet mask is 248.0.0.0

HR 10- subnet mask is 255.192.0.0

Developers 55 -subnet mask is 255.252.0.0 this fall under 64 bit

Network Team 5-subnet mask is 248.0.0.0

In this case you should include ERP and CRM systems to help enterprises share data smoothly among department

Static IPs for few servers because this address is not secure hackers might take advantage of it but by reducing the number of servers may work well. 

Need for High level of redundancy -Network redundancy is the process of adding additional instances of network devices and lines of communication to help ensure network availability and decrease the risk of failure along the critical data path.

Businesses that offer Wi-Fi access to visitors are seeing higher sales and customer satisfaction, while Wi-Fi at the business drives employee productivity and collaboration.  Employees rely on Wi-Fi more than ever to perform their jobs and stay productive.

Monitoring of network-the use of <span style="font-size:10.0pt;line-height:107%;font-family: &quot;Helvetica&quot;,&quot;sans-serif&quot;;color:#0D47A1;border:none windowtext 1.0pt;mso-border-alt: none windowtext 0in;padding:0in;background:white">Simple Network Management Protocol</span>. SNMP is a device protocol that provides monitoring tools and nodes a common language to communicate with each other. An SNMP manager sends out polls to devices to inquire about their current status, and devices can send traps when significant network events occur.

 

Network troubleshooting -It's a logical process that network engineers or IT professionals use to resolve network problems and improve network performance. In this department there should be an engineer that deals with troubleshooting problems if incase of any occurrence he is available to fix arising problem.

Types of network security:-

1.Access Control :

This mechanism is used to stop unattended access to data which is being send. It can be achieved by various techniques such as applying passwords, using firewall.

Digital Signature :

This security mechanism is achieved by adding digital data that is not visible to eyes. It is form of electronic signature which is added by sender which is checked by receiver electronically.
