Ccna 3 Examen Final De Habilidades De Ensa Ptsa Work |top| -

The CCNA 3 ENSA Final PT Skills Assessment (PTSA) requires completing several critical network configuration tasks in Packet Tracer, ranging from physical device placement to advanced security and routing. Part 1: Physical Placement and Basic Setup

In this assessment, you must work in Physical Mode, meaning you must place devices correctly on the rack and tables before they can be configured.

Rack Placement: Place Router 1 (top), Router 2, and Switches 1–4 in descending order on the rack.

Table Placement: PC-C and the DNS server go on Table 1 (left). PC-A and PC-B go on Table 2 (right).

Connectivity: Connect devices using the correct copper straight-through or crossover cables based on the provided topology. Part 2: Core Device Configuration

Basic settings must be applied to all routers (R1, R2) and switches (S1–S4) via console connection.

Hostnames & Security: Disable domain lookups, set hostnames, and encrypt all clear-text passwords. Passwords: Secret: ciscoenpass Console: ciscoconpass Minimum Length: 10 characters.

SSH Management: Configure a domain name (e.g., ccna-lab.com), generate 1024-bit RSA keys, and set VTY lines to use local authentication and transport input ssh. Part 3: Routing and Security

OSPFv2: Configure single-area OSPF using process ID 1 or 10 as specified. Manually set router IDs (e.g., 0.0.0.1 for R1) and use network statements with inverse masks. Access Control Lists (ACLs):

Create standard ACLs to restrict VTY line access (often allowing only PC-C).

Implement extended ACLs to restrict traffic like FTP or SSH from the internet while allowing specific public services. NAT/PAT: Static NAT: Map an internal server to a public IP address.

Dynamic PAT: Create a NAT pool and use an access list (e.g., ACL 1) to allow internal LANs to share public IP addresses. Part 4: Network Management

NTP: Configure routers to synchronize time with an NTP server.

Maintenance: Back up running configurations and IOS images to a TFTP server.

Updates: Some versions require updating a switch to a newer IOS version located on the TFTP server.

For detailed step-by-step command scripts, you can refer to guides on platforms like InfraExam or ITExamAnswers.

CCNA 3: Enterprise Networking, Security, and Automation (ENSA) Skills Assessment (PTSA) Final Exam Preparation Guide

The CCNA 3 ENSA Skills Assessment, often referred to as the PTSA (Packet Tracer Skills Assessment), is the final practical hurdle in the Cisco Networking Academy v7 curriculum. This exam tests your ability to integrate complex configurations across a simulated enterprise network. Unlike the multiple-choice final, this assessment requires you to prove you can actually build, secure, and troubleshoot a modern network. Understanding the Scope of the ENSA PTSA

The PTSA is a comprehensive lab. It focuses on the transition from basic connectivity to advanced enterprise services. You are expected to demonstrate proficiency in:

Layer 2 Security: Implementing Port Security, DHCP Snooping, and DAI.

Routing Protocols: Configuring OSPFv2 (Single-Area or Multi-Area) for IPv4 and IPv6.

Redundancy: Setting up First Hop Redundancy Protocols like HSRP.

Network Management: Configuring SNMP, Syslog, and NTP for monitoring.

Automation and WAN: Implementing NAT, ACLs, and basic VPN concepts. Key Configuration Checkpoints

To succeed in the "examen final de habilidades," you should master the following configuration blocks. 1. OSPFv2 and OSPFv3 Configuration

OSPF is the backbone of the ENSA exam. You will likely need to configure a multi-area OSPF environment or a single-area setup with specific link costs.

Process ID and Router ID: Always manually assign a Router ID to ensure stability. Network Commands: Use wildcard masks for IPv4.

Passive Interfaces: Disable OSPF updates on LAN-facing interfaces to enhance security and reduce traffic.

Default Route Propagation: Use the default-information originate command on the edge router. 2. Standard and Extended IPv4 ACLs ccna 3 examen final de habilidades de ensa ptsa work

Access Control Lists are used for more than just blocking traffic; they are essential for NAT and securing management access.

Placement: Place Extended ACLs as close to the source as possible. Place Standard ACLs as close to the destination as possible.

Named vs. Numbered: Practice using Named ACLs, as they are easier to edit during the exam.

Management Plane: Apply ACLs to VTY lines to restrict SSH access to specific administrative workstations. 3. NAT for IPv4

You will almost certainly be asked to configure Dynamic NAT with Overload (PAT).

Define the Inside/Outside Interfaces: Forgetting ip nat inside or ip nat outside is a common reason for failure.

Define the Interesting Traffic: Use an ACL to permit the internal private subnets.

The Translation Command: ip nat inside source list [ACL_#] interface [Outside_Int] overload. 4. Switch Security and LAN Redundancy

The ENSA curriculum places a heavy emphasis on mitigating common attacks.

DHCP Snooping: Define trusted ports (uplinks) and untrusted ports (user access).

Port Security: Set a maximum number of MAC addresses and configure the violation mode to restrict or shutdown.

HSRP: Configure high availability for the gateway. Ensure you set the priority and preempt commands correctly on the primary router. Troubleshooting Strategy for the PTSA

The Packet Tracer environment can be unforgiving. If your "Completion" percentage isn't hitting 100%, check these three areas:

Link Local Addresses: In IPv6 OSPF, ensure you have configured Link-Local addresses (FE80::) as they are often required for neighbor adjacency scoring.

Clock Synchronization: Ensure NTP is working. If the clocks are off, Syslog and SNMP scores might not trigger.

The "Copy Run Start" Factor: Always save your configuration. While some PT versions auto-save progress, others require a manual save to register certain scoring milestones. Preparation Checklist

Review the Lab Instructions: Read the entire addressing table before typing a single command.

Verify Connectivity: Use ping and traceroute at every major step. Don't wait until the end to find a routing loop.

Check Management Access: Verify that SSH is functional and that the domain name and RSA keys are correctly generated.

Audit Security: Ensure all unused ports are shut down and assigned to a "black hole" VLAN.

To help you get ready for your specific version of the ENSA exam, I can provide more targeted help if you share a few details:

Are you working on a Multi-Area OSPF or Single-Area OSPF version? Does your lab focus more on IPv4 NAT or IPv6 Routing?

Are you having trouble with a specific scoring component (like HSRP or ACLs)?

I can provide specific command syntax or a step-by-step logic flow for any of these topics.

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. The CCNA 3 ENSA Final PT Skills Assessment

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 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
