En la mayoría de los exámenes ENSA PTSA, tendrás que configurar NAT para que las PCs internas salgan a Internet usando una única dirección pública.
Este es el núcleo de CCNA 3. Debes saber configurar OSPF en los routers.
Caso típico del examen hot:
Ejemplo de ACL extendida:
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).

Antes de entrar en los comandos, entiende la estructura. El examen dura aproximadamente 2 horas (dependiendo de tu instructor) y consta de 3 a 6 preguntas prácticas en Packet Tracer o hardware real.
Los temas estrella del CCNA 3 ENSA son:
Atención: El término "PTSA" sugiere que te darán una topología predefinida con errores ("broken config") que debes identificar y corregir, además de nuevas configuraciones.
El ccna 3 examen final de habilidades de ensa ptsa hot no es imposible, pero exige precisión. Aquí tienes tu plan de acción:
Recuerda: El "Hot" del examen significa que debes mantener la calma bajo presión. Usa show para verificar cada paso. No avances a la siguiente sección sin confirmar que la actual funciona.
¡Buena suerte, futuro CCNA! Que el protocolo OSPF te guíe y las ACLs no te bloqueen el camino. ccna 3 examen final de habilidades de ensa ptsa hot

In this physical mode assessment, you must place and connect hardware before any configuration occurs.
Device Placement: Correctly position Routers (R1, R2) and Switches (S1–S4) into the rack from top to bottom.
End Device Setup: Move PCs (PC-A, PC-B, PC-C) and the DNS server to their designated tables and power them on.
Cabling: Use appropriate cables (e.g., straight-through for router-to-switch and crossover for router-to-router) to match the provided topology. Part 2: Basic Device Configuration
Standard security and management settings must be applied to all networking hardware.
Global Settings: Configure hostnames, disable domain name lookups, and set a minimum password length.
Access Security: Encrypt the privileged EXEC secret and set passwords for console and VTY lines.
Interface Setup: Assign IPv4 addresses and descriptions to router interfaces (G0/0/0, G0/0/1, G0/0/2) and activate them.
Remote Management: Enable SSH version 2 with a 1024-bit RSA key and a local administrative user for secure access. Part 3: Advanced Routing & Network Services
This section focuses on the technical implementation of core ENSA concepts.
OSPFv2 Configuration: Implement single-area OSPF routing using Process ID 1 and manual Router IDs (e.g., 0.0.0.1 for R1). En la mayoría de los exámenes ENSA PTSA,
NAT Implementation: Configure Static NAT for specific servers and Dynamic NAT with PAT for internal network groups.
Access Control Lists (ACLs): Deploy various ACL types on routers and switches to manage traffic flow and enhance security.
Network Management: Set up a router with NTP as a system time source and perform backups of device configurations and IOS images to a TFTP server. Helpful Resources

CCNA 3 ENSA Final PT Skills Assessment (PTSA) focuses on advanced enterprise networking, specifically OSPFv2, NAT, and network security. This exam is typically completed in Packet Tracer’s Physical Mode
, requiring you to manually rack and cable devices before beginning configuration. Part 1: Build the Network (Physical Mode) Device Placement
: Move routers (R1, R2) and switches (S1-S4) into the main wiring closet rack from top to bottom. End Devices
: Place PC C and the DNS server on Table 1 (left side); place PC A and PC B on Table 2 (right side). Ejemplo de ACL extendida: access-list 100 deny ip 192
: Connect devices according to the provided topology, ensuring you use the correct interface types (e.g., Gig0/0/0 for router-to-switch links). Part 2: Initial Device Settings Basic Config
: Set hostnames, disable DNS lookup, and configure secret passwords for all routers and switches. IP Addressing
: Assign IPv4/IPv6 addresses to router interfaces, switch SVIs, and host PCs based on the provided addressing table. SSH Management : Configure SSH with a domain name (e.g., ccna-lab.com ), local admin user, and VTY line restrictions.

CCNA 3 ENSA (Enterprise Networking, Security, and Automation) Final PT Skills Assessment (PTSA)
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.
