Network Troubleshooting Activity

This repository contains a practical hands-on activity on Network Troubleshooting completed as part of a university course in Computer Information Systems (CIS). The document demonstrates essential networking tools and techniques to diagnose and resolve network-related issues. The goal was to apply hands-on troubleshooting techniques to resolve real-world network problems effectively.

Project Overview

This project involves completing and documenting tasks from Hands-On Activity 5A (CIS 2347). It focuses on the following areas of network troubleshooting:

• Analyzing IP configurations and connectivity using commands like IPCONFIG, PING, and ARP.
• Investigating Domain Name System (DNS) issues and caching mechanisms.
• Implementing advanced tools like NSLOOKUP and TRACERT to trace routes and find IP addresses.
• Identifying common failure points in network operations.

Features

• Detailed Command Demonstrations:
  • Commands like IPCONFIG /DISPLAYDNS, PING, and TRACERT are explained with output examples.
• Diagnostic Insights:
  • How tools like ARP and DNS Cache contribute to resolving network inefficiencies.
• Failure Analysis:
  • Comprehensive listing of potential failure points in a request lifecycle, including AWS-specific issues like:
    • DNS resolution and API gateway failures.
    • Misconfigurations in IAM policies and VPC settings.
    • Issues with services like ELB, EC2, and RDS.
