Answer:
Organizations use different kinds of networks based on their size, budget, and requirements. A local area network (LAN) is suitable for small organizations with a limited number of devices. LAN connects devices within a limited area, such as a building or a campus. Wide area networks (WAN) are used to connect devices over a larger geographical area. WAN can connect devices across cities, countries, or continents. Organizations may also use a virtual private network (VPN) to securely connect remote workers to the organization's network.
The network topology depends on the organization's requirements. A bus topology is suitable for small networks, while a star topology is used in larger networks. In a bus topology, devices are connected to a single cable. In a star topology, devices are connected to a central hub or switch. A ring topology is used in networks where all devices are connected in a loop.
Security measures are essential to protect networks from internal and external threats. External threats include hackers, viruses, and malware, while internal threats include unauthorized access by employees. Organizations use firewalls, intrusion detection systems (IDS), and intrusion prevention systems (IPS) to prevent external threats. Firewalls filter incoming and outgoing traffic based on predefined rules. IDS and IPS detect and prevent attacks in real-time. Organizations also use encryption to protect sensitive data.
Administrators constantly monitor the network to ensure its smooth functioning. They use network monitoring tools to identify and resolve issues. They also perform regular backups and disaster recovery planning to prevent data loss in case of a network failure.
If you were to interview a network administrator, they may have unique insights into the specific challenges and opportunities of their organization's network. They may also have suggestions for improvements or updates to the network infrastructure to better meet the organization's needs.
