I am preparing for the CompTIA Security+ certification and want targeted, exam-style tutoring that zeroes in on Network Security—specifically firewalls and VPNs. The goal is to master the current exam objectives, clear up any conceptual gaps, and build enough confidence to score well on test day. Sessions should be live, interactive, and paced to my schedule. I learn best when theory is tied directly to hands-on examples, so walking through real-world firewall rules, VPN configurations, and related packet-flow scenarios is essential. Explanations must stay aligned with the Security+ wording and depth so I recognize the phrasing when it appears on the exam. Deliverables: • A structured lesson plan broken into manageable milestones • Live tutoring sessions with screen-sha...

This project covers the end-to-end creation of a brand-new Local Area Network for our premises. The environment will serve daily operations for both computers and servers as well as our shared printers and scanners, so stability, speed, and clean segmentation matter. The scope begins with planning: assessing the floor layout, sizing the switch stack, deciding on cable runs, and selecting hardware that fits future growth. Layer-2 and Layer-3 configuration must follow best practices—think VLAN separation for user groups, QoS where printing traffic needs it, and a security baseline that shuts unused ports, enforces 802.1X, and applies sensible ACLs at the edge. During implementation, I expect neat rack work, labelled cabling, and documented configurations (Cisco-style CLI or equivalen...

I have several Cisco-based lab and production environments that need hands-on attention from someone who already feels at home with CCNA-level work. Over the next few weeks I’ll be refining network configuration, tightening security, and—most importantly—sorting out a few stubborn routing-protocol issues that keep popping up. Here’s the situation: • Network configuration needs polishing on a mix of Catalyst switches and ISR routers, including VLAN planning, trunking, and interface tuning. • Day-to-day troubleshooting consumes far too much time; I want clear root-cause analysis when links flap, routes disappear, or access lists misbehave. • Security hardening is overdue—standard ACLs are in place, but I need smarter filtering and a quick r...
