Network Engineer Professional Certificate

Build, secure and automate networks with Cisco Packet Tracer, following the Cisco CCNA (200-301) exam topics from first principles to exam practice.

Learn how networks and the internet work, then address and subnet them, switch and route them, run their services, secure them and automate them with Python. Each course follows the published CCNA exam topics for its area, with labs in Cisco Packet Tracer, and the series ends with a full exam-preparation course. It's independent of Cisco and doesn't give you a Cisco certification, but it prepares you for the exam.

Prepares you for

Network engineer, Network administrator, Network support technician, NOC engineer

  • Networking Fundamentals: How Networks and the Internet Work: Understand how data crosses networks and the internet, from cables and switches to IP, TCP and DNS, and troubleshoot a connection yourself. (Beginner, about 9.5 hours)
  • IP Addressing and Subnetting: IPv4 and IPv6: Read, plan and configure IPv4 and IPv6 addresses with confidence, from binary and masks to subnetting, VLSM and SLAAC, proved on devices in Packet Tracer. (Beginner, about 12 hours)
  • LAN Switching: VLANs, Trunks and Spanning Tree: Configure, verify and troubleshoot Cisco switched networks: VLANs, 802.1Q trunks, inter-VLAN routing, Rapid PVST+ and EtherChannel, built and tested in Packet Tracer. (Intermediate, about 12 hours)
  • IP Routing: Static Routes and OSPF: Read routing tables, build static, default and floating routes, run single-area OSPFv2 and keep gateways available with HSRP, on Cisco routers in Packet Tracer. (Intermediate, about 13 hours)
  • IP Services: DHCP, DNS, NAT, NTP and Network Management: Configure and verify the services every IP network depends on, from DHCP, DNS and NAT to NTP, syslog, SNMP, SSH and configuration backups, on Cisco routers in Packet Tracer. (Intermediate, about 10 hours)
  • Network Security and Wireless Fundamentals: Protect a Cisco network from the router to the access port: harden device access, filter traffic with ACLs, stop Layer 2 attacks, and build wireless LANs secured with WPA2 and WPA3. (Intermediate, about 12 hours)
  • CCNA Exam Preparation: Practice Labs and Review: Review all six CCNA (200-301) domains with Packet Tracer practice labs, learn a structured troubleshooting method, and prove your skills on a multi-site network you build and then fix. (Intermediate, about 14 hours)
