Network+: CompTIA Network+

Network+ validates the essential knowledge needed to design, configure, manage, and troubleshoot wired and wireless networks. It covers the OSI model, IP addressing (IPv4/IPv6), network security, and troubleshooting methodologies, providing a vendor-neutral foundation. It is considered a prerequisite "foundation" certification before moving into specialized security roles, as you cannot secure a network you do not understand. The exam includes performance-based questions that test your ability to troubleshoot connectivity issues and configure basic network devices. It ensures a solid grasp of ports, protocols, and topology.
