When you are planning a network, strong design policies are very important to ensure the system works well both now and in the future. One of the most critical policies is security. A network must have rules that control who can access it and how data is protected, such as through firewalls, strong passwords and encryption. Without security, the network becomes an easy target for attacks. Another key policy is scalability. A good network design should be able to grow as the company or organization grows. This means making sure there is room to add new devices, users, and applications without needing to completely redesign the system. Finally, a quality of service policy helps keep important traffic flowing smoothly. By prioritizing business critical applications such as video calls or database access, the network reduces delays and ensures users can stay productive. Together, these policies create a reliable and an effective network.
