Essential Topics to Master
OSI Model Layers
- Physical: Cables, hubs, signals
- Data Link: Switches, MAC addresses, frames
- Network: Routers, IP addresses, packets
- Transport: TCP/UDP, ports, segments
- Session: Session management
- Presentation: Data formatting, encryption
- Application: HTTP, FTP, DNS, DHCP
Critical Port Numbers
- FTP: 20/21 | SSH: 22 | Telnet: 23
- SMTP: 25 | DNS: 53 | DHCP: 67/68
- HTTP: 80 | POP3: 110 | IMAP: 143
- HTTPS: 443 | SMB: 445 | RDP: 3389
Subnetting
You must be able to quickly determine:
- Network and broadcast addresses
- Number of usable hosts
- Subnet masks in CIDR notation
- Valid host ranges
Pro Tip: Practice Subnetting Daily
Subnetting appears throughout the exam. Practice until you can calculate subnet information in your head. Use online subnetting practice tools daily during your study period.
Troubleshooting Methodology
- Identify the problem
- Establish a theory of probable cause
- Test the theory to determine cause
- Establish a plan of action
- Implement the solution or escalate
- Verify full system functionality
- Document findings, actions, and outcomes
Network Tools to Know
- ping: Test connectivity
- traceroute/tracert: Map network path
- nslookup/dig: DNS troubleshooting
- ipconfig/ifconfig: View IP configuration
- netstat: View network connections
- Wireshark: Packet analysis
- nmap: Network scanning
- arp: View ARP cache
Frequently Asked Questions
How long should I study for CompTIA Network+?
Most candidates need 2-3 months of study time, dedicating about 10-15 hours per week. Those with prior networking experience may need less. Focus on both conceptual understanding and practical application of networking principles.
What is the Network+ exam format?
The CompTIA Network+ exam consists of up to 90 questions to be completed in 90 minutes. Question types include multiple-choice and performance-based questions. The passing score is 720 out of 900.
Should I get A+ before Network+?
While not required, CompTIA recommends having A+ certification or equivalent knowledge before attempting Network+. The A+ provides foundational IT knowledge that makes Network+ concepts easier to understand.
How much does the Network+ exam cost?
The CompTIA Network+ exam costs $358 USD. Look for exam bundles or academic discounts to save money on your certification journey.
Is Network+ harder than CCNA?
They cover different scopes. Network+ is vendor-neutral and broader, while CCNA is Cisco-specific and deeper. Many find CCNA more challenging due to its hands-on requirements, but Network+ covers more general concepts.
