Which of the following is usually NOT provided redundantly in data centers?

The correct answer is B. Air flow. Data centers invest heavily in redundancy for critical systems: dual or multiple electrical feeds (often from separate utility sources plus UPS and generators), redundant cooling units (N+1 or 2N configurations), and multiple network uplinks to different providers. Air flow…

Explanation

Data centers invest heavily in redundancy for critical systems: dual or multiple electrical feeds (often from separate utility sources plus UPS and generators), redundant cooling units (N+1 or 2N configurations), and multiple network uplinks to different providers. Air flow, while managed through raised floors, hot/cold aisle containment, and directional venting, is not typically duplicated as a redundant independent system in the same way. The physical airflow paths and ductwork are not provisioned with a standby duplicate - instead, redundancy is achieved through the cooling units themselves, not the airflow delivery mechanism.
