Troubleshooting network services requires a systematic approach and the capacity to identify and resolve issues, especially those related to network operations like connectivity problems, slow performance, or service outages. In this course, you'll explore how to troubleshoot common cabling, physical interface and network service issues. First, you'll learn how to distinguish between frequently encountered cabling issues. Then, you'll learn about common hardware issues related to Power over Ethernet (PoE) and transceivers as well as common switching issues as they relate to STP, VLAN assignment, and ACLs. You'll also troubleshoot regular network services issues. Finally, you'll study a range of frequently occurring issues that impact switches, route selection, address pools, default gateways, as well as IP addresses and subnet masks. This course is one of a collection that helps prepare learners for the CompTIA Network+ (N10-009) certification exam.
