Task 1
You are required to evaluate a WAN and answer the questions that follow;
1. Identify the method of WAN Implementation.
11. Identify the WAN categories of network components, their functions and examples.
111. Explain the features and constraints of the WAN system
IV. Assess and report on the suitability of the network for its use.
V. Compare alternative network design that could have been used.
Task 2
You are required to develop any 2-network administration document for the WAN system that you were analysing in Task 1 above. Attach the network administration.
Task 1: Evaluation of a WAN
1. Method of WAN Implementation:
The WAN in question is implemented using a combination of leased lines and virtual private networks (VPNs). Leased lines provide dedicated point-to-point connections between different locations, ensuring reliable and secure data transmission. VPNs, on the other hand, allow remote access to the network through encrypted communication over the internet.
11. WAN Categories of Network Components:
- Routers: These devices are responsible for directing data packets between different networks. Examples include Cisco routers.
- Switches: Switches are used to connect devices within a network and are essential for data flow control. Examples include Aruba switches.
- WAN Optimizers: These devices help optimize data flow over the WAN, improving network performance. Examples include Riverbed WAN optimizers.
III. Features and Constraints of the WAN System:
Features:
- High-speed data transmission.
- Secure connections through encryption.
- Remote access capabilities.
- Scalability to accommodate growth.
Constraints:
- Cost of leased lines.
- Potential for network congestion.
- Vulnerability to cyber attacks.
IV. Suitability of the Network for its Use:
Overall, the WAN system is suitable for its intended use, providing reliable and secure connectivity between different locations. However, the cost of leased lines and potential network congestion should be carefully managed to ensure optimal performance.
V. Alternative Network Design:
An alternative network design could involve implementing a software-defined WAN (SD-WAN) architecture. SD-WAN offers centralized network management, improved performance, and cost savings compared to traditional WAN architectures.
Task 2: Network Administration Documents
1. Network Configuration Guide:
This document provides step-by-step instructions for configuring routers, switches, and WAN optimizers within the network. It includes details on IP addressing, routing protocols, VLAN configuration, and security settings.
2. Network Monitoring and Troubleshooting Guide:
This document outlines procedures for monitoring network performance and troubleshooting common issues. It includes information on tools and techniques for monitoring bandwidth usage, identifying network congestion, and resolving connectivity issues.
