How to use it in an answer
A model sentence
“Authorised users can access the data and system when needed; supported by backups, redundancy and protection against denial of service.” Then apply it: A backup server keeps the site available if the main one fails.
In a short answer, give the definition in your own words first, then tie it to the situation in the question. Do not copy the example above unless it fits the scenario.
Technique for the question types
- Multiple choice: Read all four options, rule out wrong ones, pick one; no penalty for guessing so never leave blank.
- Matching or table: Tick or match each statement to the right column (for example ORM v SQL, SAST v DAST).
- Fill in the blanks: Choose the right word from a list; use exact syllabus terms.
Common mistakes
- Use the term exactly as the syllabus words it, then link it to the scenario in the question; the 2025 feedback repeatedly rewards using the stimulus.
- Answer the command word: outline gives main points only, explain gives a reason or cause, discuss gives both sides.
