Question

which of the following will help reduce the threat of static discharge when working on computer hardware? (select two.)
reduce the humidity in the room to around 30%.
store unused components in static shielding bags.
place your hardware on an insulating layer of 1/4 inch styrofoam.
touch the leads on the pc components with your finger to dissipate static charge.
leave the system plugged into a grounded wall outlet.
remain in physical contact with the server chassis at all times.

Explanation:

1. Store unused components in static shielding bags: Static shielding bags prevent static from affecting components by providing a conductive layer that dissipates static charges, protecting the components.
2. Remain in physical contact with the server chassis at all times: The server chassis is grounded (if the system is properly set up), so maintaining contact with it keeps you at the same potential as the chassis, preventing static discharge between you and the hardware.

Let's analyze the incorrect options:

• Reducing humidity to 30% increases static risk (higher humidity reduces static).
• Placing hardware on Styrofoam (an insulator) doesn't help with static discharge; it can even accumulate static.
• Touching leads with fingers can damage components (ESD from you to component) and doesn't dissipate static safely.
• Leaving the system plugged in (but not properly grounded or with power on) can be dangerous and doesn't help with static discharge (in fact, if the system is on, it's a different risk, and if off but plugged to a grounded outlet, the chassis is grounded, but the option of remaining in contact with chassis is better; just plugging in isn't the action to reduce static discharge directly as the main action is touching the chassis).

Answer:

• Store unused components in static shielding bags.
• Remain in physical contact with the server chassis at all times.
