Computer network assignments can often be daunting, especially for students new to the field. Whether you're tackling subnetting problems or troubleshooting network issues, it's essential to have a solid understanding of the concepts involved. That's where our expert solutions come in handy. Let's dive into a couple of master-level questions along with their solutions to give you a taste of what we offer.

Question 1:
You've been tasked with designing a network for a medium-sized company. The company requires separate networks for different departments, including Sales, Marketing, and IT. Each department should have its own subnet, and there should be interconnectivity between them. Design a suitable network topology for this scenario.

Solution:
To design an efficient network topology for the company, we'll opt for a hierarchical structure, commonly known as the hierarchical network design model. This model consists of three layers: Core, Distribution, and Access.

• Core Layer: This layer is responsible for high-speed backbone connectivity. It interconnects different distribution layer devices and provides fast transportation between them.
• Distribution Layer: The distribution layer aggregates the traffic from access layer devices and provides connectivity to the core layer. It also performs routing, filtering, and WAN access.
• Access Layer: The access layer connects end devices, such as computers, printers, and servers, to the network. It's responsible for user access and provides connectivity to the distribution layer.

For our scenario, we'll allocate separate VLANs for each department at the access layer and configure inter-VLAN routing at the distribution layer using Layer 3 switches. This setup ensures isolation between departments while allowing communication when necessary.

Question 2:
You're troubleshooting a network connectivity issue where a workstation in the Sales department cannot access resources on the Marketing department's server. Identify and troubleshoot the possible causes of this problem.

Solution:
When troubleshooting network connectivity issues, it's crucial to follow a systematic approach to identify and resolve the underlying problems. Here are some steps you can take:

1. Check Physical Connections: Start by ensuring that all physical connections, including cables and connectors, are properly seated and functional. A loose or faulty connection could be the culprit.
2. Verify IP Configurations: Verify the IP configurations of the workstation and the server. Ensure that they are in the correct subnet and have the appropriate gateway configured.
3. Check VLAN Configurations: Since the departments are on separate VLANs, verify that the workstation and server are assigned to the correct VLANs and that VLAN trunks are properly configured on the switches.
4. Inspect Access Control Lists (ACLs): Check if there are any access control lists configured on the switches or routers that could be blocking traffic between VLANs. Make necessary adjustments if required.
5. Test Connectivity: Use tools like ping or traceroute to test connectivity between the workstation and the server. This can help pinpoint where the issue lies.

By systematically troubleshooting each potential cause, you can identify and resolve the network connectivity issue efficiently.
