• Flag difficult questions and return later
• Budget time: 60 min multiple choice, 40 min simulations, 20 min review

Common Mistakes to Avoid

1. 1 ❌ Not practicing enough with Packet Tracer/GNS3
2. 2 ❌ Memorizing without understanding concepts
3. 3 ❌ Skipping subnetting practice
4. 4 ❌ Ignoring automation topics (10% of exam!)
5. 5 ❌ Not taking practice exams
6. 6 ❌ Rushing through simulations

Simulation Tips

1. 1 Read requirements carefully - every word matters
2. 2 Start with "show" commands to understand topology
3. 3 Use exact Cisco IOS syntax (case-sensitive)
4. 4 Verify configuration before moving on
5. 5 Don't over-complicate - simplest solution is usually correct
