Description
CompTIA a+ Network is a 25-hour, beginner-friendly course focused on networking fundamentals for entry-level IT and support roles.
Training combines instructor-led lessons, demonstrations, practical exercises, and troubleshooting scenarios covering TCP/IP, IP addressing, DNS, DHCP, network operations, enterprise applications, Linux server basics, automation essentials, and data management. Participants learn how networks are structured, monitored, and supported in business environments.
After completion, learners can explain core networking concepts, support basic network operations, identify common connectivity issues, and continue preparing for CompTIA networking-related certification study.
What You Will Learn
Topic 1: Networking Fundamentals
Review TCP/IP, IPv4 and IPv6 addressing, subnetting, DNS, DHCP, NAT, common ports, protocols, and the OSI model.
Identify routers, switches, wireless access points, firewalls, cables, connectors, and basic network services.
Topic 2: Enterprise Applications
Study common business application services, including web, database, directory, email, file, and remote access services.
Review how enterprise applications depend on network availability, authentication, logging, and service configuration.
Topic 3: Network Operations
Work with network documentation, change records, asset information, diagrams, monitoring, and basic service checks.
Practice operational tasks used in small business and enterprise environments.
Topic 4: Network Troubleshooting Fundamentals
Apply structured troubleshooting methods for connectivity, DNS, DHCP, routing, wireless, and performance issues.
Use tools such as ping, traceroute, nslookup, dig, ip, netstat, ss, tcpdump, and Wireshark.
Topic 5: Linux Server Basics
Use Linux command-line tools to inspect files, users, permissions, processes, services, logs, and network settings.
Topic 6: Automation Essentials
Practice basic Bash scripting, variables, conditionals, loops, scheduled tasks, and simple automation for repeatable support work.
Topic 7: Data Management
Review data storage, backups, permissions, retention, integrity checks, and basic database concepts.
The course combines instructor-led teaching, demonstrations, guided labs, and case-based troubleshooting. After completion, participants should be able to explain core network services, perform basic Linux server tasks, create simple Bash scripts, support enterprise application connectivity, and troubleshoot common network issues in a documented, repeatable way.
Certification & Exam
CompTIA a+ Network is a beginner stepping stone toward the CompTIA Network+ N10-009 certification, not a replacement for full Network+ exam preparation. It introduces core networking topics and can help participants assess readiness before moving into complete Network+ training.
Participants may complete the course’s own a+ Network CompCert assessment. Those who pass can download a Competency Certificate from the provider, showing completion of this course assessment. This certificate is separate from the official CompTIA Network+ certification. To earn Network+, candidates must register for and pass the official CompTIA Network+ N10-009 exam through CompTIA’s testing process. For current exam objectives, format, scoring, and policies, refer to the official CompTIA Network+ certification page.
What You Will Achieve
Identify common network types, topologies, and devices, including routers, switches, modems, firewalls, wireless access points, servers, and end-user systems.
Apply core IP networking concepts, including IP addresses, subnet masks, default gateways, DHCP, DNS, Ethernet, Wi-Fi, and basic device connectivity.
Configure basic network settings on Windows and Linux devices to support local network access, internet connectivity, and shared services.
Manage Linux server basics, including user accounts, groups, services, file ownership, file permissions, and common command-line administration tasks.
Create basic Bash scripts to automate routine support tasks, such as checking system status, managing files, running commands, and producing simple logs.
Explain database and data management fundamentals, including basic database operations, data storage concepts, backup methods, and restore considerations.
Support enterprise applications on networks by checking connectivity, verifying service access, reviewing basic logs, and documenting application-related issues.
Troubleshoot common connectivity, server, automation, data, and application issues using a structured process that includes testing, isolation, documentation, and escalation when needed.
