The CCNA 3 ENSA Final Packet Tracer Skills Assessment (PTSA) focuses on advanced enterprise networking concepts like OSPFv2, NAT, and ACLs. This guide follows the standard v7.0 curriculum flow to help you navigate the final practical requirements. Part 1: Physical Placement and Basic Settings
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.
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: ccna 3 examen final de habilidades de ensa ptsa work
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 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. The CCNA 3 ENSA Final Packet Tracer Skills
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
