Question 1: Designing a Scalable Network Infrastructure

You've been tasked with designing a network infrastructure for a medium-sized company with offices in multiple locations. The network must be scalable to accommodate future growth, resilient to minimize downtime, and secure to protect sensitive data. How would you approach this design challenge?

Solution:

To design a scalable network infrastructure for the company, we would first conduct a thorough analysis of their current requirements and anticipated future growth. This would involve gathering information about the number of employees, their network usage patterns, the types of applications they use, and any projected expansion plans.

Based on this analysis, we would then design a hierarchical network architecture, with core, distribution, and access layers. The core layer would consist of high-speed switches or routers to provide fast and reliable connectivity between different parts of the network. The distribution layer would handle routing between different subnets and provide access control and policy enforcement. Finally, the access layer would connect end-user devices such as computers, printers, and IP phones to the network.

To ensure scalability, we would use technologies such as VLANs (Virtual Local Area Networks) to segment the network into smaller, more manageable broadcast domains, and implement dynamic routing protocols like OSPF (Open Shortest Path First) or EIGRP (Enhanced Interior Gateway Routing Protocol) to allow for automatic network reconfiguration as new devices are added.

In terms of resilience, we would implement redundant links and devices at critical points in the network to minimize the risk of single points of failure. This could include using technologies like Spanning Tree Protocol (STP) to prevent loops in the network and implementing redundant power supplies and network connections for critical devices.

Finally, to ensure security, we would implement measures such as access control lists (ACLs) to restrict access to sensitive data, encryption to protect data in transit, and intrusion detection systems (IDS) to monitor for any unauthorized access attempts.

By following these principles and leveraging the latest networking technologies, we can design a scalable, resilient, and secure network infrastructure that meets the needs of the company both now and in the future.

Question 2: Implementing Quality of Service (QoS) for VoIP Traffic

Your organization has recently deployed a VoIP (Voice over Internet Protocol) system for internal communication, but users are experiencing poor call quality during periods of high network congestion. How would you implement Quality of Service (QoS) to prioritize VoIP traffic and improve call quality?

Solution:

To improve call quality for VoIP traffic, we would implement Quality of Service (QoS) mechanisms to prioritize voice packets over other types of traffic on the network. This involves identifying VoIP traffic, marking it with the appropriate priority level, and then giving it preferential treatment as it traverses the network.

One approach to implementing QoS for VoIP traffic is to use DiffServ (Differentiated Services), a protocol that allows network devices to classify and prioritize traffic based on the value of the DiffServ Code Point (DSCP) in the IP header. We would configure routers and switches throughout the network to recognize VoIP packets based on their DSCP value and then assign them to a high-priority queue with guaranteed bandwidth and low latency.

Additionally, we could use traffic shaping and traffic policing techniques to limit the bandwidth consumed by non-essential traffic during periods of congestion, ensuring that VoIP packets have sufficient bandwidth to maintain call quality.

By implementing these QoS mechanisms, we can prioritize VoIP traffic on the network and ensure that users experience high-quality voice calls even during periods of heavy network usage.
