How to use it in an answer
A model sentence
“Internet Message Access Protocol: lets you read and manage email on the server and keeps all your devices in sync.” Then apply it: IMAP keeps messages on the server.
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.
What the marking guidelines and feedback say
Know: SMTP sends/transfers mail between servers (and from client to server); POP3 downloads mail to the device (usually removing it from the server); IMAP keeps mail on the server and synchronises across devices.
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.
