CompTIA A+ Core 2 (220-1002) — Question 340

Which of the following are best practices to avoid ESD-related damage when handling internal computer components? (Choose two.)

Answer options

• A. Ground oneself before touching components.
• B. Avoid exposing components to sources of RFI.
• C. Maintain cool and dry air in the work environment.
• D. Handle cards by their edges to avoid contacting ICs.
• E. Wear adequate eye protection at all times.
• F. Ensure hardware is plugged into a grounded outlet.

Correct answer: A, D

Explanation

Grounding oneself before touching components (A) helps prevent static electricity from damaging sensitive parts. Handling cards by their edges (D) ensures that you do not touch any integrated circuits directly, which could also lead to ESD damage. The other options, while important for overall safety and component care, do not specifically address ESD prevention.
