Project 1
Network & Wi-Fi Troubleshooting - DNS Fault Simulation & Recovery
Project Type: Personal Practical Lab
Focus: Network Troubleshooting, DNS, Wi-Fi Connectivity
Platform: Windows Networking
Tools: Command Prompt, ipconfig, ping, nslookup, ipconfig/flushdns
Status: Completed ✅
Project Overview
This practical lab was designed to simulate a real-world network troubleshooting scenario where a computer is connected to Wi-Fi but experiences a DNS resolution problem.
I followed a structured troubleshooting process to:
Check the computer's IP configuration.
Test connectivity to the local network gateway.
Test external Internet connectivity.
Identify a DNS resolution failure.
Restore the DNS configuration.
Flush the DNS resolver cache.
Verify that DNS resolution was working again.
The objective was to practice a structured, evidence-based troubleshooting approach rather than simply guessing the cause of a network problem.
Evidence

🎯 Project Outcome
The lab demonstrated my ability to follow a structured troubleshooting methodology:
Check → Test → Diagnose → Fix → Verify
Skills demonstrated:
Network & Wi-Fi Troubleshooting · IPv4 · DHCP · DNS · ipconfig · ping · nslookup · Fault Diagnosis · Recovery & Verification
Project 2
Backup & Data Recovery Simulation - Data Loss & File Recovery
Project Type: Personal Practical Lap
Platform: Windows 11 Pro
Focus: Backup . Data Recovery . Data Protection . File Management
Status: Backup & Revocery Verified ✅
Project Overview
I performed a practical backup and recovery lab to simulate a real-world situation where an important user file is accidentally deleted.
The objective was to create a backup, verify that the backup was accessible, simulate data loss, restore the deleted file from the backup, and confirm that the original data was successfully recovered.
Evidence
Screenshot1 - Test Data Preparation
Step 1 — Prepare Test Data
I created and organized three test .txt files inside an IT_Backup_Test folder:
Project_Report.txt
Important_Data.txt
User_Document.txt
Screenshot 2 - Backup Created
Step 2 — Create the Backup
I created a separate backup destination:
C:\IT_Backup_Lab\Backup_01
I then copied the three test files from the source folder into the backup location.
Screenshot 3 - Backup Verification
Step 3 — Verify the Backup
I opened Important_Data.txt directly from the backup location and confirmed that the file opened successfully and contained the original information.
This verified that the backup copy was accessible and contained the expected data.
Screenshot 4 - Simulated Data Loss
Step 4 — Simulate Data Loss
To simulate an accidental deletion scenario, I deleted:
Important_Data.txt
from the original IT_Backup_Test folder.
The backup copy was intentionally left untouched.
Screenshot 5 - File Recovery
Step 5 — Restore the Deleted File
I located Important_Data.txt in:
C:\IT_Backup_Lab\Backup_01
and copied it back into the original:
IT_Backup_Test
The deleted file was successfully restored.
Screenshot 6 - Recovery Verification
Step 6 — Verify the Recovery
I opened the restored Important_Data.txt and confirmed that the original text was still present.
This confirmed that the file had been successfully recovered and that the expected data was preserved.
Final Result
The complete backup and recovery process was successfully completed:
Create → Backup → Verify → Simulate Data Loss → Restore → Verify ✅
The deleted test file was successfully recovered from the backup, and its original contents remained intact.
