Join CommunityStudy Tips
Hands-On Practice is Essential
- Spend at least 40% of study time doing hands-on labs, not just watching videos
- Use Packet Tracer daily - build the same topology multiple times until configuration is automatic
- Break equipment in labs intentionally, then practice troubleshooting to fix it
- Create your own lab scenarios based on exam topics rather than only following guided labs
- Document your configurations in a notebook - writing reinforces memory
Master Subnetting Completely
- Practice subnetting until you can calculate any subnet in under 60 seconds without tools
- Use the subnetting practice website daily for at least 20 problems
- Learn both the traditional method and shortcut techniques
- Don't rely on calculators - the exam doesn't allow them for subnetting questions
- Practice IPv6 address shortening and expansion - it's commonly tested
Focus on Cisco-Specific Implementations
- Understand Cisco command syntax, not just theory - exact commands are tested
- Know Cisco's default settings (STP mode, OSPF cost calculations, etc.)
- Learn to read 'show' command outputs - you'll get multiple simulation questions
- Understand Cisco's three-tiered hierarchical model (access, distribution, core)
- Know the differences between Cisco proprietary and open standard protocols
Practice Exam Strategy
- Take practice exams under timed conditions starting at week 8
- Review every wrong answer thoroughly - understand why you missed it
- Flag difficult questions and move on - don't get stuck on one question
- For simulation questions, verify your configuration with show commands before moving on
- Score 85%+ consistently on Boson exams before scheduling your real exam
Memorization Techniques
- Create mnemonics for OSI layers, port numbers, and protocol suites
- Use flashcards (Anki or Quizlet) for commands, port numbers, and definitions
- Build comparison tables for similar technologies (HSRP vs VRRP, RADIUS vs TACACS+)
- Draw network diagrams repeatedly from memory to reinforce topology concepts
- Record yourself explaining concepts and listen during commute
Don't Neglect Automation Domain
- Many candidates fail by ignoring the automation section - it's 10% of your score
- You don't need to be a programmer, but understand JSON/YAML structure
- Know REST API basics: GET, POST, PUT, DELETE operations and status codes
- Understand configuration management concepts and why automation is beneficial
- Use Cisco DevNet sandbox for hands-on practice with APIs - it's free
Troubleshooting Methodology
- Learn Cisco's structured troubleshooting approach (bottom-up, top-down, divide-and-conquer)
- Practice reading and interpreting show commands: show ip interface brief, show ip route, show spanning-tree
- Understand common error messages and what they indicate
- For simulation questions, use verification commands to confirm your solution works
- Build a mental troubleshooting flowchart for common issues
Exam Day Tips
- 1Arrive at the test center 30 minutes early; bring two forms of ID (one must be government-issued with photo)
- 2Read each question carefully - Cisco questions often include unnecessary information to distract you
- 3Budget your time: 120 minutes for 100-120 questions means about 60-70 seconds per question
- 4Answer simulation questions carefully - they're worth more points but take more time (5-10 minutes each)
- 5Use the erasable noteboard provided immediately to write down memory dumps (subnetting chart, port numbers, OSI model)
- 6Flag difficult questions and return to them later - don't let one hard question consume too much time
- 7For multiple-choice questions with multiple correct answers, the exam will tell you how many to select
- 8Trust your first instinct unless you find clear evidence you were wrong upon review
- 9There's no penalty for guessing - never leave a question unanswered
- 10Take the optional break after simulation questions if you need it to reset mentally
- 11Stay calm if you see unfamiliar topics - not every question counts toward your score (some are experimental)
- 12Review all flagged questions if time permits before submitting the exam
