Ccna 3 Examen Final De Habilidades De Ensa Ptsa Hot < 2025 >

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.

Si tienes una duda específica sobre un comando o un concepto de configuración, siéntete libre de preguntar y te ayudaré a entenderlo.

CCNA 3 ENSA Final PT Skills Assessment (PTSA) is a critical hands-on component of the Cisco Networking Academy's "Enterprise Networking, Security, and Automation" (ENSA) course

. Unlike standard assessments, it often requires students to work entirely in Packet Tracer's Physical Mode , simulating the manual setup of a server room. 1. Physical Device Placement and Cabling

The most distinctive challenge of this exam is the requirement to physically place and power on equipment within the wiring closet. Rack Configuration

: You must move routers (typically R1 and R2) and switches (S1–S4) from the shelf to the rack in a specific top-to-bottom order. Workstation Setup

: End devices like PC-A, PC-B, and DNS servers are placed on specific tabletop areas (e.g., Table 1 or Table 2) before they can be configured. Power and Cables

: Connectivity only works once devices are powered on and physically cabled according to the provided (but often hidden) logical topology. 2. Core Technical Configuration Tasks

Once the physical setup is complete, you must configure a secure enterprise network. Detailed guides on sites like ITExamAnswers highlight these key areas: CCNA3 v7 – ENSA Hands On Skills Exam Answers - InfraExam ccna 3 examen final de habilidades de ensa ptsa hot

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:

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. I understand you're asking for help with the

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):

Static NAT: Map a single internal server (like a web server) to a public IP. Si tienes una duda específica sobre un comando

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.

It sounds like you’re looking for a feature list or summary for the CCNA 3 (Enterprise Networking, Security, and Automation – ENSA) final skills-based exam (often called the Practical PT Skills Exam or "Hot" lab) in Packet Tracer.

Below is a breakdown of typical features you need to configure on this exam, based on the official Cisco CCNAv7 curriculum.

access-list 100 deny ip 192.168.10.0 0.0.0.255 192.168.100.0 0.0.0.255
access-list 100 permit ip any any

Aplicar en interfaz: ip access-group 100 in (en la interfaz del router conectada a Ventas).

interface g0/1
 ip nat outside

access-list 1 permit 192.168.1.0 0.0.0.255
ip nat inside source list 1 interface g0/1 overload

En la parte de seguridad, debes proteger los puertos de acceso contra ataques MAC flooding.

El CCNA 3 v7 - ENSA (Enterprise Networking, Security, and Automation) representa la tercera y última parte del currículo oficial de Cisco antes del examen de certificación CCNA 200-301. Dentro de este curso, el Examen Final de Habilidades (PTSA - Packet Tracer Skills Assessment) , conocido coloquialmente como el "examen hot" o "PT Hot", es la prueba práctica definitiva.

A diferencia de los exámenes teóricos de opción múltiple, el PTSA (Prototype Testing Skills Assessment) evalúa tu capacidad para:
