What type of keyboard is required for the online exam?

• A. A USB keyboard only.
• B. A touchscreen keyboard is sufficient.
• C. A laptop keyboard must be closed when using external monitor.
• D. A laptop or external keyboard; if using a laptop with an external monitor, the laptop screen must be closed.

Answer: (D)

This question tests what input devices are allowed for the online exam and how to configure the laptop when an external monitor is used. The best choice reflects both flexibility and a specific safety/consistency rule: you can use either a laptop keyboard or an external keyboard, and if you’re using a laptop with an external monitor, you must close the laptop screen. This setup gives you the option to bring your own keyboard or rely on the laptop’s keyboard, while the lid-closure requirement ensures the built-in keyboard and the laptop’s display aren’t part of the testing setup when an external monitor is in use, keeping the test environment stable and compliant with proctoring rules. The other options are too narrow or incomplete: insisting on a USB keyboard only excludes valid wireless or built-in options, a touchscreen keyboard generally isn’t acceptable as the sole input method for a formal exam, and requiring the laptop keyboard to be closed only in the presence of an external monitor doesn’t fully capture the allowed configurations and the lid rule.
