CCNA 3: Examen Final de Habilidades de ENSA (PTSA) - Guía Completa de Preparación

El examen CCNA 3 ENSA (Enterprise Networking, Security, and Automation) v7.0 representa la culminación del currículo de Cisco Networking Academy. El Examen Final de Habilidades Prácticas (PTSA) es una de las pruebas más exigentes, ya que requiere que el estudiante demuestre su capacidad para configurar, asegurar y solucionar problemas en redes empresariales complejas utilizando Packet Tracer.

A continuación, desglosamos los componentes clave y las configuraciones esenciales que suelen evaluarse en este examen. 1. Configuración de OSPFv2 de Área Única

El corazón del enrutamiento en CCNA 3 es OSPF. Deberás configurar la conectividad básica y el ajuste de parámetros:

Identificación del Router: Configuración manual del router-id.

Anuncio de Redes: Uso de comandos network con sus respectivas máscaras wildcard o configuración directa en interfaces.

Interfaces Pasivas: Evitar el envío de saludos OSPF en interfaces que dan hacia redes LAN para mejorar la seguridad.

Ajuste de Prioridades y Costos: Modificación del ancho de banda de referencia para adaptarlo a velocidades modernas (Gigabit/Ten-Gigabit) y ajuste manual del costo de interfaz. 2. Seguridad de Capa 2 y Conmutación (Switching)

El examen ENSA pone un énfasis crítico en proteger la infraestructura de acceso. Los temas recurrentes incluyen:

Implementación de VLANs y Trunks: Configuración de enlaces troncales IEEE 802.1Q y asignación de puertos a VLANs específicas. ccna 3 examen final de habilidades de ensa ptsa work

Seguridad de Puertos (Port Security): Limitación del número de direcciones MAC permitidas por puerto y definición de acciones en caso de violación (shutdown, restrict o protect).

Mitigación de ataques de Capa 2: Configuración de DHCP Snooping para prevenir servidores DHCP maliciosos y DAI (Dynamic ARP Inspection) para evitar ataques de envenenamiento de ARP.

3. Listas de Control de Acceso (ACLs) Estándar y Extendidas

Las ACLs son la herramienta principal para filtrar el tráfico en el PTSA. Es probable que se te pida:

ACLs Extendidas IPv4: Filtrar tráfico basado en origen, destino, protocolo y número de puerto (por ejemplo, permitir solo HTTP/HTTPS hacia un servidor específico).

ACLs de IPv6: Implementación de filtrado similar para redes de próxima generación.

Ubicación de ACLs: Aplicar las listas "lo más cerca posible del origen" (para extendidas) o "lo más cerca posible del destino" (para estándar). 4. NAT y Automatización de Red

Para garantizar la conectividad a Internet y la eficiencia operativa:

NAT Dinámico con Sobrecarga (PAT): Configuración de una lista de acceso para identificar el tráfico interno y su traducción a una única dirección IP pública.

Conceptos de Automatización: Aunque el PTSA es principalmente de configuración manual en Packet Tracer, es vital entender cómo herramientas como REST API, JSON y lenguajes como Python interactúan con dispositivos mediante controladores (Cisco DNA Center). 5. Gestión y Monitorización Finalmente, la salud de la red debe ser supervisada:

SNMP y Syslog: Configuración de dispositivos para enviar registros de eventos a un servidor centralizado.

NTP (Network Time Protocol): Asegurar que todos los dispositivos tengan la hora sincronizada para que los logs sean coherentes cronológicamente.

SSH: Deshabilitar Telnet y configurar acceso remoto seguro mediante el uso de nombres de dominio y generación de llaves RSA. Consejos para el Éxito en el PTSA

Lea los requisitos minuciosamente: A menudo, un error en la máscara wildcard o un nombre de VLAN mal escrito (sensible a mayúsculas) puede invalidar toda la sección.

Verificación constante: Utilice comandos como show ip ospf neighbor, show ip interface brief y show running-config después de cada paso importante.

Gestión del tiempo: Packet Tracer puede ser lento al converger; use el botón de "Fast Forward Time" para acelerar procesos de STP y OSPF.

¿Necesitas ayuda con algún comando de configuración específico de OSPF o de seguridad de puertos para tu práctica?

3. Divide y vencerás: La regla de los 4 pasos

Para cada dispositivo, aplica:

  1. Configuración básica (hostname, banners, contraseñas, encripción de contraseñas, logging synchronous, exec-timeout)
  2. Capacidad de capa 3 (IP en interfaces, estado "up/up", rutas)
  3. Servicios y seguridad (ACLs, SSH, DHCP, HSRP)
  4. Verificación (show ip route, show standby brief, show access-lists, ping extendido)

Mastering the CCNA 3 PTSA Final: A Comprehensive Guide to Skills Assessment Success

The CCNA 3 ENSA (Enterprise Networking, Security, and Automation) Final PT Skills Assessment (PTSA) is a hands-on practical exam conducted entirely in Packet Tracer's Physical Mode. Unlike standard logical topology labs, you must physically place devices on racks and cable them manually before beginning configurations. Core Assessment Objectives

The exam typically follows a multi-part structure designed to test your ability to build, secure, and maintain a medium-sized enterprise network:

Physical Setup: You are tasked with placing routers (R1, R2) and switches (S1-S4) into specific rack slots and arranging PCs and servers on designated worktables.

Initial Configuration: This includes setting up IPv4 addresses for hosts, configuring basic router/switch settings (hostnames, banners, passwords), and enabling secure remote access via SSH/VTY.

Routing & Optimization (OSPFv2): A major portion of the work involves activating Single-Area OSPFv2 using process IDs, setting router IDs, and adjusting OSPF operations, such as modifying auto-cost and configuring passive interfaces. Network Security (ACLs & NAT):

NAT: Implementing static NAT for internal servers and dynamic PAT for LAN hosts.

ACLs: Creating and applying standard and extended Access Control Lists to restrict VTY access and manage network traffic.

Device Management: You must back up running configurations to a TFTP server and perform an IOS software update/upgrade using a provided image file. Preparation Resources

For a detailed walkthrough of these steps, you can refer to comprehensive guides and practice materials from ITExamAnswers and InfraExam. ENSA Final Skills Exam PTSA

CCNA 3 ENSA Final PT Skills Assessment (PTSA) requires you to build, configure, and secure a network topology in Packet Tracer's physical mode. The primary objective is to demonstrate proficiency in OSPFv2 routing, NAT, and Access Control Lists (ACLs) to ensure secure enterprise-level connectivity. Part 1: Physical Topology Setup The assessment often begins in the Physical Mode

of Packet Tracer, requiring you to organize the wiring closet. Device Placement

: Move routers (R1, R2) and switches (S1, S2, S3, S4) from the shelf to the rack in the specified top-to-bottom order. End Devices

: Place PC A and PC B on the right table (Table 2), and PC C and the DNS Server on the left table (Table 1).

: Ensure all devices are powered on. In physical mode, you may need to manually click power buttons or connect to the power distribution unit.

: Connect the devices according to the network topology provided in your specific exam variant. Part 2: Basic Configuration and SSH

You must configure management security and standard interface settings. Global Settings

: Set hostnames, disable DNS lookup, and configure encrypted passwords. SSH Management Set the domain name (e.g., ccna-lab.com Create a local user (e.g., Username: admin Secret: admin1pass Generate a 1024-bit RSA key and enable SSH version 2.

Configure VTY lines to use the local database and only permit SSH. Interface Addressing

: Assign IPv4 addresses and descriptions to router interfaces (G0/0/0, G0/0/1, G0/0/2) and switch SVI (VLAN 1). Part 3: Single-Area OSPFv2 Routing

Configure the routing protocol to enable communication between different network segments. Activation router ospf 1 on R1 and R2. Router IDs : Manually set IDs (e.g., for R1 and Network Statements : Add the connected networks using wildcard masks (e.g., network 192.168.1.0 0.0.0.255 area 0 Optimization Network Configuration : Candidates will be required to

: Configure passive interfaces on LAN links to enhance security and efficiency. Part 4: Security and NAT

This section secures the network and manages external traffic.

CCNA 3 ENSA Packet Tracer Skills Assessment (PTSA) is the final practical hurdle where you transition from a student to a network architect. In this simulation, you aren't just clicking buttons; you are the lead technician tasked with stabilizing and securing a branch office network. The Story: The "First Day" Crisis

Imagine it is your first day at a new company. You arrive to find the networking closet in chaos. Your mission is to bring order to this digital frontier across five critical stages: The Physical Foundation

: You start in "Physical Mode," where you must literally place , and four switches (

) into the equipment rack. You organize the cables, ensuring PC A and PC B are on their correct desks and the DNS server is properly seated. Securing the Gateways : Once powered on, you lock down the devices. You configure

for secure remote management, set up local administrative users, and ensure the domain name ccna-ptsa.com

is active so no unauthorized person can tamper with your new setup. Mapping the Paths : To make sure data knows where to go, you activate Single-Area OSPFv2

. You assign Router IDs and customize the protocol so that R1 and R2 can "talk" to each other and share the best routes across the office. Guardians of the Perimeter : Now for the "Security" in ENSA. You configure Access Control Lists (ACLs)

to block suspicious traffic while allowing legitimate users through. You then set up (Network Address Translation) and

so that multiple devices inside the office can share a single public IP to reach the internet. The Safety Net

: Before heading home, you perform a critical backup. You use a TFTP server to save your working configuration and even upgrade the IOS software

on a router to ensure the network is running the latest, most secure version of Cisco's "brain". CCNA3 v7 – ENSA Hands On Skills Exam Answers - InfraExam
