Which of the following is a prime advantage of having a server rack?
  1. Eliminates the need for multiple cooling fans
  2. Eliminates the need for multiple RAM modules
  3. Eliminates any worries about environmental factors
  4. Racks have low friction rails for easy access
Explanation
Answer - D - The main advantage of having a server rack is that server racks have low friction rails for easy access.

Key Takeaway: A server rack contains multiple mounting slots, called bays, each designed to hold a hardware unit secured in place with screws. Rack equipment chassis slide smoothly in and out on low-friction rails for easy access. A single rack can contain multiple servers stacked one above the other, consolidating network resources and minimizing the required floor space.
