Assessment criteria
Topic Overview
The City & Guilds Level 2 Diploma in ICT Systems Support is a vocational qualification designed to equip students with the practical skills and knowledge needed to provide first-line technical support in a variety of ICT environments. This diploma covers essential areas such as computer hardware, software installation, networking fundamentals, and customer service skills. Students learn to diagnose and resolve common hardware and software issues, set up and maintain computer systems, and communicate effectively with end-users. The qualification is ideal for those seeking entry-level roles in IT support, such as helpdesk technician or IT support assistant.
This diploma is structured around real-world scenarios, ensuring that students gain hands-on experience with troubleshooting, system configuration, and network connectivity. Topics include understanding the components of a computer system, installing and configuring operating systems, setting up local area networks (LANs), and applying health and safety practices. The course also emphasises the importance of data security and backup procedures. By the end of the programme, students should be confident in providing efficient and professional ICT support, making them valuable assets to any organisation's IT department.
The City & Guilds Level 2 Diploma in ICT Systems Support fits into the wider subject of Computer Science by focusing on the practical application of technology. While Computer Science often delves into theoretical concepts like algorithms and programming, this diploma bridges the gap between theory and practice. It prepares students for the demands of the workplace, where problem-solving, technical proficiency, and customer service are key. This qualification is also a stepping stone to further study, such as the Level 3 Diploma in ICT Systems Support or apprenticeships in IT support.

Assessment Guidance
Guidance for achieving higher grades
- 💡Follow installation guides step by step.
- 💡Test client connectivity thoroughly.
- 💡Use monitoring tools to check system health.
- 💡In practical assessments, always verify auto-discovery and client sign-in as a first step before tackling advanced features.
- 💡When troubleshooting, use the OCS 2007 R2 Resource Kit tools proactively—especially the Validation Wizard to check topology configuration.
- 💡For Enterprise Voice tasks, systematically define voice policies by site then apply global settings, ensuring PSTN usage records align with voice routes.
- 💡Demonstrate edge configuration by enabling external federation and testing with a known external domain to prove successful setup.
- 💡Always validate each configuration step with a real client test, such as signing in from an external network after setting up Edge Server connectivity.
- 💡During practical assessments, document each step with screenshots and explanations, as assessors award marks for clear, logical evidence of process.
- 💡For Enterprise Voice tasks, double-check your normalization rules against the provided dial plan specification to ensure compliance before testing.
- 💡Familiarize yourself with common troubleshooting tools like the OCS Logging Tool and Event Viewer; be prepared to identify errors in a broken configuration.
- 💡Familiarise yourself with the server topology and roles.
- 💡Use best practices for security and redundancy.
- 💡Follow installation steps in order.
- 💡Double-check network prerequisites.
- 💡Use troubleshooting tools like logging and monitoring.
- 💡When answering questions about troubleshooting, always follow a logical step-by-step process: identify the problem, establish a theory of probable cause, test the theory, implement a solution, verify functionality, and document findings. This structured approach gains marks.
- 💡Know the difference between hardware and software faults. In exams, clearly state whether an issue is likely hardware (e.g., beep codes, no power) or software (e.g., error messages, slow performance) and justify your reasoning.
- 💡For networking questions, memorise the OSI model layers (especially Physical, Data Link, Network, Transport, and Application) and common protocols at each layer. Use mnemonics like 'Please Do Not Throw Sausage Pizza Away' to recall the order.
Common Mistakes
Common errors to avoid in your coursework
- Misconfiguring DNS or certificate settings.
- Overlooking firewall rules for external access.
- Poor monitoring leading to undetected issues.
- Overlooking DNS SRV record requirements (_sipinternaltls and _sipfederationtls) leading to client sign-in or federation failures.
- Misconfiguring certificate subject names or not including all required service names (e.g., sip.domain.com, ocs.domain.com) causing trust errors.
- Neglecting to configure QoS (Quality of Service) settings on network hardware, resulting in poor call quality or conferencing performance under load.
- Failing to correctly plan and implement dial plans and normalization rules, causing Enterprise Voice call routing issues to external numbers.
- Assuming OCS 2007 R2 automatically updates all client-side firewall exceptions; leaving required ports blocked and preventing client communication.
- Failing to install all required prerequisites before attempting OCS installation, leading to component failures during setup.
- Misconfiguring certificate requirements for external connectivity, especially for Edge Server roles, resulting in client authentication errors.
- Confusing Enterprise Voice number normalization patterns, causing calls to fail or route incorrectly.
- Overlooking the importance of firewall port configurations for external access, blocking necessary SIP or media traffic.
- Not accounting for SQL Server collation settings when installing the backend database, which can cause issues with OCS schema deployment.
- Misconfiguring firewall settings for external access.
- Not testing voice functionality after configuration.
- Misconfiguring DNS or certificate settings for external access.
- Overlooking firewall rules for SIP traffic.
- Failing to test conferencing features after configuration.
- Misconception: 'All computer problems are caused by viruses.' Correction: Many issues are due to hardware faults, driver conflicts, or user error. Always check simple things like cables and power before assuming malware.
- Misconception: 'IP addresses are permanent and never change.' Correction: IP addresses can be dynamic (assigned by DHCP) or static. In many networks, devices receive a new IP each time they connect.
- Misconception: 'More RAM always makes a computer faster.' Correction: Adding RAM only improves performance if the system is currently limited by insufficient memory. If the CPU or storage is the bottleneck, extra RAM won't help.
