Join CommunityStudy Tips
Subnetting Mastery
- Practice subnetting calculations daily for at least 10 minutes until you can complete them in under 30 seconds
- Use the 'binary method' or 'shortcut method' - pick one and master it completely
- Create flashcards with different subnet mask notations (CIDR, dotted decimal, binary)
- Practice both forward (given network, find details) and reverse (given requirements, design network) problems
- Use online subnetting games to make practice more engaging
Port Numbers and Protocols
- Memorize at minimum the top 30 well-known ports (0-1023) and their associated protocols
- Create mnemonic devices for difficult-to-remember ports (e.g., 'HTTPS ate won' for 443)
- Understand not just the number but also the protocol's purpose and whether it uses TCP or UDP
- Group protocols by function (web, email, file transfer, remote access) for easier recall
- Quiz yourself randomly throughout the day using flashcard apps like Quizlet or Anki
Hands-On Lab Practice
- Install and configure Packet Tracer or GNS3 within your first week of study
- Complete at least 20 hands-on lab scenarios before taking the exam
- Practice using command-line tools (ping, tracert, ipconfig, nslookup, netstat) in both Windows and Linux
- Build common network scenarios from scratch (VLAN configuration, routing protocols, ACLs)
- Document your lab configurations - this reinforces learning and mimics real-world practices
Performance-Based Questions (PBQs)
- PBQs appear at the beginning of the exam - don't spend too much time if stuck; flag and return later
- Practice with simulation software to become comfortable with drag-and-drop and configuration interfaces
- Common PBQ topics include: configuring VLANs, troubleshooting with command output, matching cables/connectors, network diagram completion
- Read questions carefully - they often provide more information than you initially notice
- Time management is critical - allocate 5-7 minutes per PBQ maximum on first pass
Troubleshooting Methodology
- Memorize CompTIA's troubleshooting steps in order: Identify, Establish theory, Test theory, Establish plan, Implement, Verify, Document
- The exam frequently asks 'What should you do NEXT?' - always follow the methodology in sequence
- Practice applying the methodology to real-world scenarios, not just memorizing the steps
- Understand common symptoms and their typical causes (e.g., intermittent connectivity often relates to cable/physical issues)
- Create decision trees for troubleshooting common problems to internalize the logical flow
Acronym Management
- Network+ has over 200 acronyms - create a master list and review daily
- Group acronyms by category (routing protocols, security, wireless, etc.)
- Don't just memorize the words - understand what each technology does
- Use spaced repetition software like Anki for long-term retention
- The exam often tests acronym knowledge indirectly through scenario questions
Practice Exam Strategy
- Take your first practice exam after 3-4 weeks of study to establish a baseline
- Don't just focus on your score - analyze why you missed each question
- Take at least 5 full-length practice exams before scheduling your real exam
- Aim for consistent scores of 85%+ before attempting the actual certification
- Simulate real exam conditions: 90 minutes, no notes, minimal breaks
- Review incorrect answers immediately while the question is fresh in your mind
Wireless Networking Deep Dive
- Understand the evolution and specifications of 802.11 standards (a/b/g/n/ac/ax) including frequency, speed, and range
- Know wireless security protocols in order: WEP → WPA → WPA2 → WPA3 and why each was necessary
- Memorize 2.4GHz channels (1, 6, 11 are non-overlapping) and 5GHz channel characteristics
- Understand wireless encryption types (TKIP, CCMP, AES) and authentication methods (PSK, Enterprise)
- Practice calculating EIRP and understanding dBm/dBi measurements for antenna strength
Exam Day Tips
- 1Arrive 15 minutes early to your testing center or log in 15 minutes early for online proctoring
- 2Bring two forms of ID (one government-issued photo ID) - check CompTIA's current ID requirements
- 3Skip the tutorial unless you need to calm your nerves - it counts against your exam time
- 4Write down subnet masks, port numbers, and troubleshooting steps on your provided whiteboard/paper immediately
- 5Read each question twice before selecting an answer - CompTIA questions often have subtle wording
- 6When you see PBQs at the start, quickly assess difficulty and skip if they'll take more than 5-7 minutes each
- 7Flag questions you're unsure about and review them at the end if time permits
- 8For troubleshooting questions, eliminate options that don't follow the proper methodology
- 9Watch for keywords like 'BEST', 'MOST', 'FIRST', 'NEXT' - they're critical to choosing the right answer
- 10Don't change answers unless you're certain - your first instinct is usually correct
- 11Manage your time: aim for 1 minute per multiple choice question, leaving 20-30 minutes for PBQs and review
- 12If you're stuck between two answers, consider which aligns better with CompTIA's methodology and best practices
- 13Stay calm if you encounter unfamiliar topics - the exam is scaled, and you don't need 100% to pass
- 14Take a deep breath between sections if needed, but be mindful of the clock
- 15Remember that 720/900 is passing - you can miss questions and still succeed
