If you have a specific question about a command or concept from the ENSA skills exam (e.g., “How do I configure HSRP with IPv6?” or “Why won’t my trunk form?”), I’ll be glad to explain that clearly.

The CCNA 3 ENSA Final Packet Tracer Skills Assessment (PTSA) is a comprehensive practical exam that tests your ability to build, secure, and automate an enterprise network in Physical Mode within Packet Tracer. Key Exam Features & Modules

The assessment is typically divided into five core parts, each focusing on specific networking skills:

Physical Setup & Cabling: You must place devices like routers (R1, R2) and switches (S1-S4) into a rack and connect them using the correct cables (e.g., Copper Straight-Through, Fiber) according to a provided topology.

Basic Device Configuration: This includes setting hostnames, configuring IPv4/IPv6 addresses, and securing administrative access using passwords and SSHv2.

Single-Area OSPFv2: You are required to enable OSPF routing (typically using Process ID 1), configure passive interfaces to optimize traffic, and adjust link costs to influence routing paths. Security & NAT: A major portion of the exam focuses on:

ACLs: Creating standard and extended Access Control Lists to restrict VTY access or filter specific traffic.

NAT: Configuring Static NAT for internal servers and Dynamic NAT with PAT (Overload) for general internet access.

Network Management: You may be asked to configure NTP for time synchronization and use a TFTP server to backup configuration files or upgrade IOS images. Important Physical Mode Tasks

Unlike standard logical labs, this "HOT" (Hands-On Training) exam requires specific physical interactions:

Device Placement: Moving routers and switches from the shelf to the rack in a specific order (e.g., R1 at the top, followed by R2, then switches).

End Device Setup: Placing PCs and servers on specific tables and ensuring they are powered on before configuration.

The CCNA 3 (Enterprise Networking, Security, and Automation)

(Packet Tracer Skills Assessment) is a comprehensive practical exam that tests your ability to configure and secure an enterprise network.

The review below focuses on the most likely "hot topics" and configuration tasks you will encounter in the assessment. 1. Advanced Routing: OSPFv2 (Single-Area)

This is typically the largest section of the exam. You will be expected to move beyond basic connectivity to customized operation. Activation: Enable OSPF using either the command with wildcard masks or directly on the interface. Router IDs: Manually assign 32-bit router IDs (e.g., ) to ensure stability. DR/BDR Election: Adjust interface priorities (e.g., ip ospf priority 255

) to force a specific router to become the Designated Router. Default Routes:

Configure a default static route to the ISP and propagate it using default-information originate Optimization: Passive Interfaces on LAN-facing ports to stop unnecessary routing updates. 2. Network Security & Access Control (ACLs)

The exam focuses on both standard and extended ACLs to filter traffic. Standard ACLs: Usually applied close to the destination to permit or deny specific host/network ranges. Extended ACLs: Applied close to the

to filter by protocol (TCP/UDP) or port number (e.g., HTTP/HTTPS/SSH). VTY Lines: Secure management access using an ACL applied to the access-class 3. IP Address Translation (NAT)

You will likely need to configure both static and dynamic translation for edge connectivity. Static NAT:

Mapping a single internal server (like a web server) to a public IP. Dynamic NAT with PAT:

Using an ACL to identify internal traffic and mapping it to a single public exit interface or an address pool using the 4. Device Management & Automation

Practical "hands-on" tasks often include these administrative steps: NTP Configuration:

Set one router as the system time source and others as clients. Configuration Backups: TFTP server

to back up running configurations or upgrade the Cisco IOS image. Layer 2 Security: Some versions include DHCP Snooping (trusting the port connected to the server/router) and Port Security (limiting MAC addresses). Quick Checklist for Success Key Commands to Remember OSPF Router ID router ospf [PID] router-id [ID] OSPF Priority ip ospf priority [0-255] (on interface) Propagate Default default-information originate Dynamic PAT ip nat inside source list [ACL] interface [Type] overload ACL Application ip access-group [ID] in/out

into the specific OSPFv3 (IPv6) configuration, or should we focus on the CCNA 3 - ENSA Practice PT Skills Assessment (PTSA) Answers

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).

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

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):

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.
