A technician has been asked to decide which laptop components should be cleaned on a monthly basis as part of a maintenance routine. What are two examples of components that should be included? (Choose two.)
- exterior case
- keyboard
- CPU
- optical drive
- RAM
Explanation: Routine preventive maintenance includes the cleaning of parts that can get dirty with everyday use. Internal components are not required to be cleaned as often as external parts. Nonabrasive cleaners should be used to ensure that no damage is caused to laptop components.
