IT sustainability focuses on reducing environmental impact and promoting energy efficiency in technology use. This is achieved through measures such as:
Using energy-efficient hardware
Implementing green data center practices
Adjusting power management settings
Extending equipment life cycles where possible
These practices lower energy consumption, reduce waste, and support corporate social responsibility goals.
Option B: Incorrect-frequent replacement of devices increases e-waste and is not sustainable.
Option C: Incorrect-expanding data centers generally increases environmental footprint.
Option D: Incorrect-using high-performance hardware for all tasks wastes energy when simpler systems would suffice.
Therefore, IT sustainability is improved by using efficient hardware and power settings.
