CompTIA A+ Core 1 (220-1101) — Question 342

Some keys on a user's laptop keyboard are sticking. Which of the following should the user use to clean the laptop keyboard?

Answer options

• A. Antistatic cloth
• B. Compressed air
• C. Cleaning wipe
• D. Soap and water

Correct answer: B

Explanation

Using compressed air is the most effective way to dislodge debris and dust that may be causing the keys to stick, making option B the correct answer. An antistatic cloth (option A) is good for wiping surfaces but won't remove debris lodged between keys. A cleaning wipe (option C) could leave moisture that might damage the keyboard, and soap and water (option D) are not suitable as they can harm electronic components.
