Learning path on PluralsightCOMPTIA Professional License: Complete Roadmap
Follow this path to maximize your chances of passing on the first try
Master Networking Concepts (Domain 1 - 23%)You are here
Start with the OSI model (all 7 layers and devices at each layer), TCP/IP model, and core protocols by port number (DNS 53, DHCP 67/68, HTTP 80, HTTPS 443, FTP 20/21, SSH 22, SMTP 25, SNMP 161). Practice IPv4 subnetting (CIDR notation, VLSM) and IPv6 address types.
Study Network Implementation (Domain 2 - 20%)
Learn VLANs (trunking, access ports, 802.1Q), Spanning Tree Protocol (STP/RSTP/MSTP), EtherChannel/LACP, wireless standards (802.11ax/Wi-Fi 6 and 6 GHz Wi-Fi 6E context), cable categories, fiber types (single-mode vs multi-mode), and core network services (DHCP lease process, DNS record types, NAT types).
Learn Network Operations and Cloud (Domain 3 - 19%)
Study network monitoring tools (SNMP traps, NetFlow, syslog levels), high availability concepts (FHRP - HSRP/VRRP, load balancing algorithms), network documentation (logical vs physical diagrams, rack diagrams), change management procedures, and cloud networking (VPC, SD-WAN, SD-LAN).
Learn Network Security (Domain 4 - 14%)
Cover attack types (ARP spoofing, VLAN hopping, DNS poisoning, DDoS amplification, on-path attacks), defense mechanisms (IDS vs IPS, NGFW, UTM, honeypots), VPN technologies (IPSec tunnel/transport mode, SSL VPN, split tunneling), and AAA frameworks (RADIUS, TACACS+, 802.1X NAC).
Practice Network Troubleshooting (Domain 5 - 24%)
Drill the CompTIA troubleshooting methodology (7 steps), master CLI tools (ping with TTL, traceroute, nslookup, ipconfig/ifconfig, netstat -an, arp -a, Wireshark filters), identify physical layer symptoms (attenuation, crosstalk, EMI), and practice wireless troubleshooting (channel overlap, interference, RSSI thresholds).

Quality Exam Prep Shouldn't Cost Hundreds
I'm Ran Chen, an engineer with 20+ years of coding experience. I passed my Life Insurance license, EA exam, SIE, Series 6, 63, 65, and finally the CFP® exam.
Through all these exams, one thing became clear: exam prep is expensive. But with AI, we can change that. Quality preparation can now be free for everyone.
