CompTIA Network+ Exam Tips: Pass on Your First Attempt

Expert CompTIA Network+ exam tips to pass on your first attempt. These proven test-taking strategies, subnetting shortcuts, and insider advice come from successful candidates who passed their Network+ exam.

Before the Exam

• Master subnetting: You should be able to subnet in under 30 seconds — this is non-negotiable
• Memorize ports: Know common ports cold — 20/21, 22, 23, 25, 53, 67/68, 80, 110, 143, 443, 445, 3389
• Score 85%+ consistently on practice tests before scheduling — aim for 5+ consecutive tests at this level
• Review the OSI model: Know each layer's protocols, devices, and data units (PDUs)
• Prepare your subnetting chart: Practice writing it from memory so you can do it instantly in the exam

During the Exam

• Skip PBQs at first: Do multiple choice questions first, then return to simulations with remaining time
• Use the whiteboard immediately: Write down your subnet chart before answering any questions
• Read carefully: Look for keywords like BEST, MOST LIKELY, FIRST, EXCEPT, NOT
• Eliminate wrong answers: Usually 2 answers are clearly wrong — narrow it down
• Manage time: Aim for ~1 minute per question, save 15-20 minutes for PBQs
• Check the clock: At question 30 and question 60 to ensure you're on pace

Subnetting Exam Strategies

Subnetting questions are guaranteed on Network+. Here's how to tackle them quickly:

• Write your chart immediately: Powers of 2 (2, 4, 8, 16, 32, 64, 128, 256) and CIDR conversions
• Practice CIDR notation conversions: /24 = 255.255.255.0, /25 = 255.255.255.128, etc.
• Know how to find: Network ID, broadcast address, first host, last host, number of hosts
• Use the magic number method: 256 minus subnet mask = increment
• Practice daily: Use subnetting practice tools until it's automatic

High-Yield Topics

These topics appear most frequently on the Network+ exam based on candidate feedback:

• Network troubleshooting methodology: Identify problem, establish theory, test, implement, verify, document
• Wireless security protocols: WPA2-Personal, WPA2-Enterprise, WPA3, authentication methods
• Common network attacks: DoS/DDoS, man-in-the-middle, ARP spoofing, DNS poisoning
• VLAN configuration concepts: Tagging, trunking, native VLAN, inter-VLAN routing
• Cable types and specifications: Cat5e/6/6a, fiber types, maximum distances, speeds
• Routing protocols: OSPF, EIGRP, BGP, static vs dynamic routing
• Network monitoring: SNMP, syslog, NetFlow, packet capture

Performance-Based Question (PBQ) Tips

PBQs are worth more points and test practical skills. Here's how to handle them:

• Expect 3-5 PBQs typically at the beginning of your exam
• Practice network diagram analysis: Identifying misconfigured devices, tracing paths
• Know command-line tools: ping, traceroute, nslookup, netstat, arp, ipconfig/ifconfig
• Practice Wireshark basics: Reading packet captures, identifying protocols
• Understand routing tables: Reading and interpreting route entries
• Partial credit is possible: Attempt every part even if unsure

Common Mistakes to Avoid

• Underestimating subnetting: It must be automatic — practice until you can do it in your sleep
• Confusing similar protocols: Know the differences between OSPF/EIGRP, TCP/UDP, IPv4/IPv6
• Not knowing port numbers: Memorize both TCP and UDP ports for common services
• Skipping cable/connector questions: These are easy points if you study the physical layer
• Rushing through PBQs: Read all instructions carefully; they often have specific requirements
