220-1102 Question 710
Single answerProper component handling and storageA technician is replacing several failed memory modules and network cards in a small office. The new parts arrived earlier in the week and are still in their packaging. To avoid damaging the replacement components before installation, which action should the technician take?
- A
Place the components on top of the computer case until they are needed so they can acclimate to room temperature
- B
Leave the components in their antistatic bags until installation and handle them by the edges
- C
Open all packaging first and stack the components on a wooden desk to keep them organized
- D
Touch the gold connector pins before installation to verify the components are properly grounded
Show answer and explanation
Correct answer: B
Explanation
The safest and most professional approach is to keep replacement components in antistatic packaging until they are actually needed and then handle them only by the edges. This aligns with standard ESD prevention practices commonly taught for CompTIA A+ and reflected in manufacturer handling guidance for field-replaceable parts. Sensitive devices such as memory modules and expansion cards can be damaged by static discharge that may not be visible to the technician. Best practices also include using an ESD strap or mat when available, avoiding contact with chips and connector pins, and storing parts in antistatic bags or containers rather than leaving them exposed on desks or equipment.
- A. Incorrect.
Incorrect. Placing components on top of a computer case is not a recommended storage or staging method. Even if the case is metal, setting parts loosely on the chassis increases the risk of electrostatic discharge (ESD), physical damage, or contamination. Components should remain protected in proper antistatic packaging until they are ready to be installed.
- B. Correct.
Correct. Best practice is to keep sensitive components such as RAM and NICs in antistatic bags until the moment of installation and to handle them by the edges. This reduces the risk of ESD damage and prevents oils, dirt, or moisture from contaminating contacts and chips. This is the most appropriate action for proper component handling and storage.
- C. Incorrect.
Incorrect. A wooden desk may seem safer than metal or carpet, but opening all packaging in advance unnecessarily exposes the components to ESD, dust, bending, and accidental mishandling. The misconception is that any nonmetal surface is automatically safe for loose storage. In reality, antistatic packaging provides better protection until installation.
- D. Incorrect.
Incorrect. Touching the gold connector pins is poor handling practice. The pins can be contaminated by skin oils or damaged by ESD from the technician. Proper grounding is achieved through ESD precautions such as wrist straps, mats, and controlled handling practices, not by touching the contacts.
