Cisco Discovery Designing and Supporting Computer Networks
This topic focuses on designing, implementing, and maintaining a prototype network infrastructure. It covers the practical skills needed to create a functional network and ensure its ongoing performance.
Assessment criteria
Topic Overview
The Pearson BTEC Level 4 Diploma in Professional Competence for IT and Telecoms Professionals is a work-based qualification designed for individuals already employed in the IT and telecoms sector. It focuses on developing and demonstrating the practical skills, knowledge, and behaviours required to perform effectively in a professional role. The diploma covers core areas such as communication, project management, problem-solving, and technical competence, aligning with industry standards like the SFIA (Skills Framework for the Information Age).
This qualification is part of the wider UK apprenticeship framework for IT and telecoms professionals, bridging the gap between foundational knowledge and advanced practice. It is assessed through a portfolio of evidence, reflective accounts, and professional discussions, rather than traditional exams. By completing this diploma, students prove they can apply theoretical concepts to real-world scenarios, making them valuable assets to employers and preparing them for higher-level roles or further study, such as a Level 5 Diploma or degree.
For students, this diploma is not just about passing assessments—it's about building a career. It requires self-directed learning, critical reflection, and the ability to gather and present evidence of competence. The qualification is structured around mandatory units (e.g., Professional Practice, Security) and optional units tailored to specific job roles, ensuring relevance to each learner's context. Success in this diploma demonstrates a commitment to professional development and a deep understanding of the IT and telecoms landscape.
Key Concepts
Core ideas you must understand for this topic
- →Competence-based assessment: Evidence is collected from real work activities, not simulated tasks. Students must map their evidence to specific learning outcomes and assessment criteria.
- →Portfolio building: A structured collection of work products (e.g., reports, emails, code snippets) and reflective accounts that demonstrate skills and knowledge. Each piece must be cross-referenced to the relevant unit.
- →Professional behaviours: The diploma assesses not just technical ability but also attitudes like teamwork, ethical practice, and commitment to continuous learning, as defined by the employer's occupational standards.
- →SFIA alignment: Many units map to SFIA levels, helping students understand their current proficiency and plan career progression. For example, a unit on 'Security' might correspond to SFIA level 4 (Enable).
- →Reflective practice: Students must critically analyse their own performance, identifying strengths, areas for improvement, and lessons learned. This is often documented in reflective accounts or professional discussions.
Learning Objectives
What you need to know and understand
- Be able to design a network infrastructure, Be able to implement a prototype network, Be able to maintain a prototype network
- Be able to design a network infrastructure, Be able to implement a prototype network, Be able to maintain a prototype network
Assessment Criteria
Key criteria assessors look for in your portfolio
- Design a network infrastructure meeting specified requirements.
- Implement a prototype network correctly.
- Maintain a prototype network to ensure reliability.

Assessment Guidance
Guidance for achieving higher grades
- 💡Use network diagrams to illustrate your design.
- 💡Follow a systematic approach to implementation.
- 💡Keep a log of maintenance activities.
- 💡Use network simulation tools for practice.
- 💡Follow a structured design methodology.
- 💡Test each component before full integration.
- 💡Tip 1: Use the STAR method (Situation, Task, Action, Result) when writing reflective accounts. This structure ensures you cover all aspects of competence and makes it easy for assessors to see how you met the criteria.
- 💡Tip 2: Keep a running log of your daily activities and challenges. This will help you identify potential evidence early and avoid scrambling at the end. Note down specific examples of problem-solving, communication, and technical work.
- 💡Tip 3: Engage with your assessor regularly. Ask for feedback on draft evidence and clarify any ambiguous criteria. They can guide you on what constitutes strong evidence and help you avoid common pitfalls.
Common Mistakes
Common errors to avoid in your coursework
- Overlooking security considerations in design.
- Incorrectly configuring network devices.
- Failing to test the prototype thoroughly.
- Overlooking scalability in design.
- Incorrect IP addressing or subnetting.
- Failing to document the network configuration.
- Misconception: The diploma is just about collecting documents. Correction: Evidence must be carefully selected and annotated to show how it meets specific criteria. Quantity does not equal quality; each piece should demonstrate clear competence.
- Misconception: You can use the same evidence for multiple units without changes. Correction: While evidence can be cross-referenced, it must be explicitly linked to each unit's learning outcomes. You may need to add context or additional reflections to show relevance.
- Misconception: Professional discussions are informal chats. Correction: These are structured, recorded assessments where you must articulate your knowledge and decision-making process. Prepare by reviewing your portfolio and anticipating questions about your role and choices.
