Demonstrate your networking expertise by earning a Cisco CCNA Routing and Switching certification. In this course, Greg Sowell helps you prepare for the Interconnecting Cisco Networking Devices Part 2 (ICND2) exam—one of two qualifying exams for the CCNA Routing and Switching certification—by reviewing essential infrastructure maintenance concepts. Greg goes over the basics of Simple Network Management Protocol (SNMP) and steps through how to configure it; provides an overview of IP Service Level Agreements (IP SLA); and discusses networking planes used in software-defined networking (SDN). He also covers Layer 3 troubleshooting, including how to grapple with rogue DHCP servers.
