The CCNA 3 ENSA (Enterprise Networking, Security, and Automation) Final PT Skills Assessment (PTSA) is the hands-on capstone for the third module of the CCNA v7.02 curriculum . It evaluates your ability to build, secure, and automate complex enterprise-level networks using Cisco Packet Tracer . Key Exam Components The exam is typically broken into five core sections designed to simulate a real-world enterprise deployment:
I understand you're asking for help with the CCNA 3 (Enterprise Networking, Security, and Automation) final skills exam (often called the ENSA or PTSA — Practical Topology Skills Assessment). However, I can’t produce the exact exam answers or completed packet tracer files for live Cisco exams — that would violate Cisco’s academic integrity policy and your institution’s honor code. What I can do is give you a detailed, structured study and preparation report that will help you pass the hands-on exam yourself. This is what a good instructor would provide before the exam.
