This guide covers the core requirements for the CCNA 3 Enterprise Networking, Security, and Automation (ENSA) Final Packet Tracer Skills Assessment (PTSA). This exam typically requires you to build and secure a network from scratch in Physical Mode, emphasizing OSPF, NAT, and ACLs. Part 1: Physical Topology & Connectivity

Unlike standard Packet Tracer labs, this PTSA often starts in Physical Mode. You must manually place and cable devices.

Device Placement: Move routers (e.g., R1, R2) and switches (e.g., S1–S4) from the shelf to the rack in the specified order (typically top-to-bottom).

End Devices: Place PCs and servers (like a DNS or TFTP server) on the designated tables.

Cabling: Connect devices according to the logical topology using correct cable types (Copper Straight-Through, Crossover, or Console).

Power: Ensure all devices are powered on before attempting to configure them. Part 2: Basic Configuration & Management

Secure management is a high-point task. Expect to configure:

Device Hardening: Set hostnames, disable DNS lookups, and configure encrypted passwords (service password-encryption and secret). SSH Setup: Set a domain name (e.g., ccna-lab.com). Generate an RSA key with a 1024-bit modulus.

Create a local admin user and set VTY lines to use the local database and accept only SSH.

IP Addressing: Configure IPv4/IPv6 addresses on router interfaces and switch SVIs (VLAN 1) according to the provided addressing table. Part 3: Routing with Single-Area OSPFv2 This is a critical section for connectivity.

Activation: Use a specific Process ID (e.g., router ospf 1).

Router IDs: Manually assign IDs like 0.0.0.1 for R1 and 0.0.0.2 for R2.

Network Statements: Use wildcard masks to advertise subnets or activate OSPF directly on interfaces. Optimizations: Set passive-interface on LAN-facing ports.

Adjust auto-cost reference-bandwidth to 1000 for Gigabit links.

Propagate a default route using default-information originate. Part 4: Security (ACLs) & NAT These tasks control traffic and provide internet access.

Standard ACLs: Use these for basic blocking (e.g., preventing LAN 1 from reaching LAN 2) or securing VTY lines with access-class.

Extended ACLs: Use these to block specific services, like HTTP (TCP port 80), while allowing other traffic. NAT (Network Address Translation): ¡Claro

Static NAT: Map a single internal server (like a web server) to a public IP.

Dynamic NAT with PAT: Create an access list for internal traffic and a NAT pool (if required), then apply overload to the outside interface. Part 5: Maintenance & Backup You are often required to manage device files.

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:

evaluates your ability to design and implement a secure, scalable enterprise network. This hands-on exam is typically performed in Packet Tracer's Physical Mode

, requiring you to physically place and cable devices before configuring them. Part 1: Physical Setup and Connectivity

In physical mode, you must organize the equipment rack and tables exactly as specified to receive full credit. Rack Organization

: Place routers (R1, R2) and switches (S1, S2, S3, S4) from top to bottom on the rack. Device Placement Table 1 (Left) to the left area and the DNS Server to the right area. Table 2 (Right) on the left and on the right. Power & Cabling

: Ensure all devices are powered on and connected using the correct cables (e.g., straight-through, crossover, or console) according to the provided topology. Part 2: Basic Configuration and IPv4 Addressing All device management is performed through a direct console connection Ccna 3 Examen Final De Habilidades De Ensa Ptsa Hot

The Story

It's a typical Monday morning for Carlos, a young and ambitious networking enthusiast. He had been preparing for months to pass the CCNA 3 (Cisco Certified Network Associate) exam, and today was the day of the final challenge: the PTSA (Practical Skills Assessment) exam.

As he arrived at the testing center, Carlos felt a mix of emotions: excitement, nervousness, and a hint of self-doubt. He had studied hard, but he knew that the PTSA exam was going to push his skills to the limit.

Upon entering the testing room, Carlos was greeted by a well-organized workspace with a rack of Cisco switches and routers, along with a computer terminal. He took a deep breath, booted up the terminal, and began to familiarize himself with the equipment.

The proctor provided Carlos with a written exam booklet and a set of instructions. The goal of the PTSA exam was to configure and troubleshoot a complex network topology, using a variety of Cisco devices. The exam was divided into several sections, each with its own set of challenges and requirements.

The Challenge Begins

The first section of the exam required Carlos to configure a small network with two switches and a router. The task was to create a basic network infrastructure, complete with IP addressing, VLANs, and routing. Carlos methodically worked through the configuration, using his knowledge of Cisco IOS commands and network protocols to bring the network online. Dispositivos de red (enrutadores, switches, servidores, etc

As he progressed through the sections, the challenges became increasingly complex. Carlos encountered issues with network connectivity, routing loops, and security configurations. He methodically troubleshot each issue, using his analytical skills and knowledge of network protocols to resolve the problems.

The Hotspot Section

The most challenging section of the exam, however, was the hotspot section. Carlos was presented with a complex network topology, complete with multiple routers, switches, and firewalls. His task was to configure the network to allow for secure access to a specific server, using a combination of access control lists (ACLs), firewall rules, and VPN configurations.

Carlos focused intently on the task, carefully analyzing the network topology and identifying the key components that needed to be configured. He methodically worked through the configuration, using his knowledge of network security protocols and Cisco device configurations to bring the network online.

The Final Stretch

As Carlos completed the final section of the exam, he felt a sense of accomplishment and relief. He had worked through the challenges methodically, using his knowledge and skills to overcome each obstacle.

The proctor reviewed Carlos's work, verifying that he had completed all the required tasks and configurations correctly. With a smile, the proctor informed Carlos that he had passed the PTSA exam with a high score.

The Aftermath

Carlos felt an overwhelming sense of pride and satisfaction as he left the testing center. He had pushed himself to the limit, and it had paid off. He knew that this achievement would open doors to new career opportunities and give him the confidence to tackle even more complex networking challenges.

As he looked back on the experience, Carlos realized that the CCNA 3 PTSA exam had been more than just a test of his technical skills. It had been a test of his problem-solving abilities, his attention to detail, and his perseverance.

From that day on, Carlos felt a sense of pride and accomplishment, knowing that he had earned the CCNA 3 certification and had demonstrated his expertise in networking.

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.

Understanding the Beast: The CCNA 3 Skills Exam

The "Skills Exam" is distinct from the standard multiple-choice final. This is a practical assessment. In CCNA 3 (Enterprise Networking, Security, and Automation - ENSA), you aren't just answering trivia; you are configuring.
