Assessment Requirements Overview

The clustered assessment integrates five core networking units ICTNWK424, ICTNWK429, ICTTEN417, ICTTEN419, and ICTTEN434 with the objective of evaluating a student’s ability to design, install, configure, and troubleshoot a small enterprise branch network for Gelos Enterprises.

The assessment is divided into three key parts:

  1. Case Study Scenario (Part 1) – Understanding the project’s scope, objectives, and clarifying client requirements through a role-play discussion.

  2. Network Design Document (Part 2) – Developing a comprehensive network design including topology, IP addressing, VLAN setup, NAT, ACLs, DHCP, routing, TFTP server, WAN link, and WHS considerations.

  3. Observation Checklist & Feedback (Part 3) – Evaluation of communication, design accuracy, safety awareness, and presentation effectiveness during the proposal and practical demonstrations.

Students are required to:

  • Create a detailed network design report using the given template.

  • Submit design diagrams, configuration steps, and a professional email requesting site access.

  • Present their proposed design and justify all configurations based on cost, efficiency, and security.

Guidance by the Academic Mentor

Step 1: Understanding the Scenario

The mentor began by helping the student interpret the GELOS Project Email and related scenario documents. The focus was on identifying:

  • The client’s technical requirements

  • Network scope (branch connection between offices)

  • Hardware and configuration expectations

The mentor ensured the student understood the business context and functional goals, such as enabling secure inter-office communication and remote access.

Step 2: Clarifying Requirements through Role Play

During the simulated role-play, the mentor guided the student to:

  • Greet the supervisor professionally

  • Ask relevant technical questions

  • Confirm project objectives and expected deliverables

This stage emphasized professional communication and active listening skills, aligning with workplace practices.

Step 3: Developing the Network Design Document

The mentor then assisted the student through each subsection of the design document:

  • 2.0 Introduction: Explained how to summarize project goals and client needs clearly.

  • 2.1 Network Topology: Guided in using Cisco Packet Tracer to create a clear logical diagram with appropriate device symbols, port IDs, and VLAN labels.

  • 2.2 IP Addressing Table: Demonstrated subnetting techniques and naming conventions.

  • 2.3 VLANs and Wireless: Explained VLAN segmentation for departments and wireless integration for tablets.

  • 2.4 NAT & DHCP Configuration: Taught the student to plan NAT placement for private-to-public IP translation and configure DHCP for multiple VLANs.

  • 2.6 ACLs: Discussed how to apply Access Control Lists for network security and control.

  • 2.7 TFTP Server & 2.8 WAN Link: Assisted in identifying appropriate protocols and server configuration steps for efficient backup and WAN connectivity.

  • 2.9 Security: Covered both logical (firewalls, passwords) and physical (restricted access, CCTV) controls.

  • 2.10 Routing: Explained the selection of dynamic routing protocols and passive interface setup.

  • 2.11 Network Components: Helped source component costs and justify equipment choices.

  • 2.12 WHS Section: Mentored the student on identifying workplace hazards and mitigation strategies, referencing WHS Act 2011 (NSW).

  • 2.13 Installation Plan: Showed how to build a logical step-by-step installation and testing sequence.

  • 2.14 Site Access Email: Taught professional email writing standards including timing, personnel details, and safety considerations.

  • 2.15 Backup Instructions: Guided the creation of systematic backup processes using Cisco commands and appropriate naming conventions.

Step 4: Proposal Presentation Role Play

The mentor conducted mock presentation sessions to:

  • Enhance the student’s confidence and clarity while presenting the design.

  • Reinforce the importance of explaining WHS considerations and risk mitigation.

  • Teach the articulation of budget justifications and policy compliance during feedback sessions.

Step 5: Review and Feedback

Once the document was complete, the mentor:

  • Reviewed the network design for technical accuracy and professional formatting.

  • Checked configuration logic (IP schemes, VLAN consistency, routing tables).

  • Gave feedback on areas like WHS completeness, ACL justification, and email tone.

This iterative review ensured that the student refined their submission to meet TAFE NSW standards.

Final Outcome and Learning Achievements

By the end of the mentoring process, the student had successfully:

  • Designed a functional, secure, and scalable enterprise branch network.

  • Demonstrated proficiency in:

    • IP subnetting and addressing

    • VLAN configuration

    • Routing protocol implementation

    • NAT, ACL, DHCP, and TFTP setup

    • Network documentation and proposal writing

Additionally, the student displayed strong professional communication, risk awareness, and technical presentation skills during the proposal review role play.
