Subnetting Quick Reference

/8   = 255.0.0.0       = 16,777,214 hosts
/16  = 255.255.0.0     = 65,534 hosts
/24  = 255.255.255.0   = 254 hosts
/25  = 255.255.255.128 = 126 hosts
/26  = 255.255.255.192 = 62 hosts
/27  = 255.255.255.224 = 30 hosts
/28  = 255.255.255.240 = 14 hosts
/29  = 255.255.255.248 = 6 hosts
/30  = 255.255.255.252 = 2 hosts

Study Strategies

Effective Learning Techniques

Active Recall: Test yourself frequently
Spaced Repetition: Review material at increasing intervals
Hands-On Practice: Use simulators and labs
Teach Others: Explain concepts to solidify understanding
Practice Tests: Take full-length practice exams

Exam Day Tips

Get adequate sleep the night before
Arrive early to the testing center
Read each question carefully
Flag difficult questions and return to them
Manage your time (90 minutes for ~90 questions)

Troubleshooting Methodology

7-Step Process

Identify the problem: Gather information
Establish theory: Consider probable causes
Test the theory: Confirm or eliminate causes
Establish action plan: Plan resolution steps
Implement solution: Execute the plan
Verify functionality: Confirm resolution
Document: Record findings and actions

Layer-by-Layer Troubleshooting

Start at Physical (Layer 1):
├── Check cables and connections
├── Verify link lights
└── Test with known-good equipment

Move to Data Link (Layer 2):
├── Check MAC address table
├── Verify VLAN configuration
└── Test switch port settings

Continue up the stack...
