Learning Objectives
What you need to know and understand
- Explain the principles of virtualisation including hypervisor types and resource abstraction
- Describe the key components of a data centre and their roles in supporting virtualisation
- Design a virtualisation environment based on given requirements and constraints
- Implement a virtualisation design using VMware technologies
- Evaluate the effectiveness of a virtualisation design against business objectives
Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for demonstrating understanding of Type 1 and Type 2 hypervisors and their use cases
- Award credit for identifying and explaining the function of servers, storage, networking, and facilities in a data centre
- Award credit for producing a design that includes logical diagrams, resource calculations, and justification of choices
- Award credit for showing step-by-step implementation of VMware ESXi and vCenter with correct configuration
- Award credit for evaluating the design against criteria such as performance, scalability, and fault tolerance
Assessment Guidance
Guidance for achieving higher grades
- 💡Use real-world examples to illustrate virtualisation principles
- 💡When designing, always start with requirements and constraints, then map to technical solutions
- 💡In implementation tasks, follow a logical order: install ESXi, configure networking, then storage, then create VMs
- 💡For evaluation, use specific metrics and compare alternatives
- 💡Practice with VMware software or simulators to gain hands-on experience
- 💡Always use correct terminology and define acronyms when first used in answers.
- 💡For calculation questions, show all working steps clearly, even if the final answer is correct, to gain method marks.
- 💡In case study questions, relate your answers to the specific scenario provided, not generic theory.
Common Mistakes
Common errors to avoid in your coursework
- Confusing Type 1 and Type 2 hypervisors or assuming all hypervisors are the same
- Overlooking the importance of storage and networking design in virtualisation
- Failing to consider business requirements and constraints when designing
- Implementing without proper planning or testing, leading to misconfiguration
- Neglecting to document the design and implementation process
- Misconception: The OSI model is the same as the TCP/IP model. Correction: The OSI model has 7 layers, while the TCP/IP model has 4 layers (or 5 in some versions). They are different conceptual frameworks.
- Misconception: Agile and Waterfall are interchangeable. Correction: Waterfall is sequential and rigid, while Agile is iterative and flexible. The choice depends on project requirements.
- Misconception: Encryption and hashing are the same. Correction: Encryption is reversible with a key, while hashing is one-way and used for integrity checks.
Revision Plan
How to revise this topic in 1–2 weeks
- 1Week 1: Focus on core systems theory - review the SDLC, OSI model, and network protocols. Create flashcards for key terms and take practice quizzes.
- 2Week 2: Dive into security and databases - study the CIA triad, encryption methods, and SQL. Practice writing queries and designing simple databases.
- 3Week 3: Explore project management - learn about PRINCE2, Agile, and earned value management. Work through case studies and calculate metrics.
- 4Week 4: Consolidate and practice - attempt past papers under timed conditions. Review examiner reports to understand common mistakes.
- 5Week 5: Focus on weak areas - revisit topics where you lost marks in practice. Use active recall and spaced repetition to reinforce memory.

Command Word Expectations (CITY & GUILDS LIMITED)
What examiners look for when using specific command words in this specification
Provide a balanced assessment of the pros and cons, then make a justified judgement. In City & Guilds exams, you must consider multiple perspectives and conclude with a reasoned decision.
Give a detailed account of how or why something happens, including underlying principles and mechanisms. Use examples to illustrate your points.
Perform mathematical computations and show all working. The final answer must include appropriate units and be rounded to a sensible degree of accuracy.

Step-by-Step Worked Solutions
Detailed solution breakdown for typical exam problems
Question: A network has a subnet mask of 255.255.255.240. How many usable host addresses are available per subnet? Show your working.
- 1.Step 1: Identify the number of bits borrowed. The subnet mask 255.255.255.240 in binary is 11111111.11111111.11111111.11110000, so 4 bits are used for the network portion in the last octet.
- 2.Step 2: Calculate the number of host bits. There are 8 bits in the last octet, so 8 - 4 = 4 host bits.
- 3.Step 3: Calculate the total number of addresses per subnet: 2^4 = 16.
- 4.Step 4: Subtract 2 for the network and broadcast addresses: 16 - 2 = 14 usable host addresses.
Question: A project has a budget of £50,000 and is expected to last 10 months. After 4 months, £25,000 has been spent and 30% of the work is complete. Calculate the Cost Performance Index (CPI) and Schedule Performance Index (SPI) and interpret the results.
- 1.Step 1: Calculate Earned Value (EV) = 30% of total budget = 0.30 * £50,000 = £15,000.
- 2.Step 2: Actual Cost (AC) = £25,000.
- 3.Step 3: Planned Value (PV) = 40% of budget (since 4 out of 10 months) = 0.40 * £50,000 = £20,000.
- 4.Step 4: CPI = EV / AC = £15,000 / £25,000 = 0.6.
- 5.Step 5: SPI = EV / PV = £15,000 / £20,000 = 0.75.
- 6.Step 6: Interpretation: CPI < 1 indicates cost overrun; SPI < 1 indicates behind schedule.
