Question

what method is used to ensure proper ventilation in a server room?
hot and cold aisles
internal cooling systems
maintaining a steady temperature
internal fans
i want to review this question later (optional)

Explanation:

Proper ventilation in a server room is often achieved through hot - and - cold aisles. This method helps manage airflow and temperature efficiently. Internal cooling systems mainly focus on cooling components directly, maintaining a steady temperature is a goal but not a ventilation method, and internal fans are part of cooling components, not a main ventilation method for the whole room.

Answer:

Hot and cold aisles
