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

Device Setup: Properly place and power on routers (R1, R2), switches (S1-S4), and end devices (PCs, DNS server) within the wiring closet. Router Configuration: Set Hostnames (e.g., R1, R2) and prevent domain lookups.
Secure the device with privileged EXEC secret passwords and console/VTY line passwords. ccna 3 examen final de habilidades de ensa ptsa work
Configure SSH version 2 with a 1024-bit RSA key and a local administrative user. Apply a Message of the Day (MOTD) banner.
Switch and PC Setup: Assign IPv4 addresses based on the provided addressing table. Configure Management Interfaces (SVIs) and default gateways for all switches. Part 2: Routing with Single-Area OSPFv2
OSPF Activation: Use process ID 1 and manually set Router IDs (e.g., 0.0.0.1 for R1).
Network Advertisements: Enter network statements for connected interfaces in the specified order to ensure full adjacency. Optimization:
Set the bandwidth reference for Gigabit Ethernet interfaces.
Designate a Designated Router (DR) by setting the highest interface priority on R1.
Propagate a default route to the ISP and configure passive interfaces where updates are not needed. Part 3: Security and NAT
The CCNA 3 ENSA (Enterprise Networking, Security, and Automation) Final PT Skills Assessment (PTSA) is a practical exam that requires configuring complex network services in Cisco Packet Tracer. It typically focuses on OSPFv2, NAT, ACLs, and device management. Part 1: Physical Placement and Basic Settings
Unlike many other labs, this assessment often starts in Physical Mode, where you must manually organize equipment.
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. Guía Definitiva para el CCNA 3: Examen Final
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
: Configure passive interfaces on LAN links to enhance security and efficiency. Part 4: Security and NAT

Título Sugerido: ¡Reto Superado! Dominando el Examen de Habilidades ENSA (CCNA 3) 🚀 ¡Hola a todos! 👋
Recientemente completé el Examen Final de Habilidades Prácticas (PTSA) del módulo ENSA (Enterprise Networking, Security, and Automation) de CCNA 3, y quería compartir un poco de mi experiencia y algunos consejos para quienes están en este camino.
Este examen es el "clímax" del curso, donde la teoría se encuentra con la realidad técnica. No se trata solo de saber comandos, sino de entender cómo interactúan los servicios en una red empresarial a gran escala. ¿Qué abarcó el desafío? 🛠️
Configuración Avanzada de OSPFv2: Adyacencias, áreas únicas y multiárea.
Seguridad de Red: Implementación de ACLs estándar y extendidas (IPv4 e IPv6).
Gestión de Dispositivos: Configuración de SNMP, Syslog y NTP para un monitoreo efectivo.
Automatización y Seguridad WAN: Conceptos de VPNs y optimización de tráfico. 3 Tips Clave para el PTSA: 💡
Documentación es Vida: Antes de tocar la CLI, lee bien la topología y la tabla de direccionamiento. Un error de IP al inicio arruina todo el routing.
Verificación Paso a Paso: Usa comandos show (show ip route, show ip ospf neighbor) después de cada configuración importante. No esperes al final para darte cuenta de que algo no funciona.
Cuidado con las ACL: El orden de las sentencias importa. Recuerda el "implicit deny" al final de cada lista.

Setting up initial hostnames, secure passwords, SSH (Secure Shell) access, and IPv4/IPv6 addressing for all interfaces. Routing Protocols: Configuring Single-Area OSPFv2
, which involves setting router IDs, adjusting interface priorities, and ensuring neighbor adjacencies. Network Security:
Implementing Access Control Lists (ACLs) to filter traffic and configuring NAT (Network Address Translation) to manage public/private IP traffic. Maintenance & Automation:
Performing configuration backups and IOS image updates using a TFTP server ITExamAnswers Key Technical Steps & Requirements
Here’s a structured feature breakdown of the CCNA 3 (Enterprise Networking, Security, and Automation - ENSA) Final Skills Exam (PTSA). This exam is a practical, hands-on assessment typically found in Cisco Networking Academy courses.
What is the PTSA?
The PTSA is a practical exam conducted within Cisco Packet Tracer. You are typically provided with a pre-built topology (network layout) that is partially configured or completely unconfigured. Your task is to implement specific technologies to meet the requirements of a "Customer" as outlined in the exam instructions.
The CCNA 3 curriculum shifts focus from basic routing (OSPF/EIGRP) covered in previous courses to advanced switching, redundancy, security, and management. Therefore, the PTSA heavily favors these topics.
Criterios de evaluación (100 puntos)
- VLANs configuradas correctamente: 15 pts
- Trunks y 802.1Q sin negociación: 10 pts
- SVI o router-on-a-stick y enrutamiento inter-VLAN funcional: 20 pts
- Port Security configurado y probado: 10 pts

Paso 6: NAT y DHCP (Conectividad a Internet)
Si la topología incluye un ISP simulado:
- Configura DHCP en el router cliente para entregar IPs a las PCs.
- Usa
ip nat insideen interfaces LAN, yip nat outsideen la interfaz WAN. - Define el
access-listpara el tráfico a traducir (permite redes internas). - Aplica
ip nat inside source list [ACL] interface [WAN] overload. - Prueba con
show ip nat translationsy haciendo ping a una IP externa.
1. Conoce la puntuación de cada sección
Antes de empezar, revisa el archivo de instrucciones (PDF o instrucciones incrustadas en Packet Tracer). Asigna prioridad:
- Las configuraciones que valen más puntos (por ejemplo, OSPF y HSRP suelen valer un 30% del total).
- Los aspectos de conectividad básica (ping entre redes conocidas) suelen ser requisito para que otras tareas funcionen.
Configuraciones clave (ejemplos concisos)
- VLANs y puertos de acceso (en switches S1/S2/S3):
vlan 10
name VLAN10
vlan 20
name VLAN20
interface FastEthernet0/1
switchport mode access
switchport access vlan 10
!
interface FastEthernet0/2
switchport mode access
