Question 1: Designing a Multi-Site Network
You have been tasked with designing a multi-site network for a multinational corporation. The network should facilitate seamless communication between headquarters located in New York (NY) and branch offices in London (LDN), Tokyo (TKY), and Sydney (SYD). Each site should have its own subnet, and there should be secure connectivity between all sites.

Solution:
To design this multi-site network efficiently, we will utilize the following steps:

1. Determine IP Addressing Scheme:

• Assign unique IP address ranges to each site: NY (10.0.0.0/24), LDN (10.1.0.0/24), TKY (10.2.0.0/24), and SYD (10.3.0.0/24).
• Implement subnetting to accommodate the required number of hosts at each site.

1. Configure Router Interfaces:

• Configure router interfaces with IP addresses from the respective subnets.
• Enable routing protocols such as OSPF to establish communication between sites dynamically.

1. Implement VLANs:

• Create VLANs for different departments within each site to enhance network segmentation and security.
• Assign VLAN IDs and IP addresses accordingly.

1. Establish VPN Tunnels:

• Configure VPN tunnels between headquarters and branch offices using IPsec.
• Implement encryption and authentication mechanisms to ensure secure communication over public networks.

1. Test Connectivity:

• Conduct thorough testing to verify connectivity between headquarters and branch offices.
• Use tools like ping and traceroute to diagnose and troubleshoot any connectivity issues.

By following these steps, you can design a robust multi-site network that fulfills the requirements of the multinational corporation while ensuring secure and efficient communication across all sites.

Question 2: Implementing Quality of Service (QoS)
You are required to implement Quality of Service (QoS) on a network to prioritize VoIP traffic over other types of traffic. The network consists of routers, switches, and VoIP phones, and it experiences occasional congestion during peak hours.

Solution:
To implement QoS effectively and prioritize VoIP traffic, adhere to the following guidelines:

1. Identify VoIP Traffic:

• Use access control lists (ACLs) or layer 4 port-based classification to identify VoIP traffic based on protocols such as SIP and RTP.

1. Configure Traffic Classification:

• Classify VoIP traffic into a separate class using Modular QoS CLI (MQC) on routers and switches.
• Assign a higher priority (e.g., EF - Expedited Forwarding) to VoIP traffic compared to other types of traffic.

1. Define Traffic Policing:

• Implement traffic policing to limit the bandwidth consumption of non-essential traffic classes during periods of congestion.
• Set appropriate bandwidth limits for different traffic classes to prevent oversubscription of network resources.

1. Enable Traffic Shaping:

• Implement traffic shaping to smooth out bursts of VoIP traffic and ensure consistent transmission rates.
• Configure shaping parameters such as committed information rate (CIR) and excess burst size to meet the requirements of VoIP applications.

1. Monitor and Fine-Tune:

• Continuously monitor network traffic using QoS statistics and performance metrics.
• Fine-tune QoS policies based on observed traffic patterns and user feedback to optimize network performance.

By implementing these QoS mechanisms, you can prioritize VoIP traffic effectively and mitigate congestion issues, thereby ensuring high-quality communication for users across the network.
