Segmentation Troubleshooting
RCCE students will learn network segmentation design and implementation including VLAN segmentation, micro-segmentation, zero trust network architecture, and segmentation testing. RCCE students will learn to design network segmentation architectures that limit lateral movement, implement VLANs, firewall zones, and software-defined segmentation, apply micro-segmentation to protect high-value assets, verify segmentation effectiveness through penetration testing, monitor inter-segment traffic for policy violations, troubleshoot segmentation-related connectivity issues, and maintain segmentation policies as organizational network architectures evolve across on-premises, cloud, and hybrid environments. This diagnostic course focuses on identifying, analyzing, and resolving common failures, misconfigurations, and operational issues. At an expert level, RCCE students will learn systematic troubleshooting methodologies that accelerate root-cause analysis and minimize downtime. Students work through realistic break-fix scenarios that build the diagnostic confidence needed for high-pressure production environments.
