CompTIA Security+ (SY0-501) — Question 415

A network operations manager has added a second row of server racks in the datacenter. These racks face the opposite direction of the first row of racks.
Which of the following is the reason the manager installed the racks this way?

Answer options

• A. To lower energy consumption by sharing power outlets
• B. To create environmental hot and cold isles
• C. To eliminate the potential for electromagnetic interference
• D. To maximize fire suppression capabilities

Correct answer: B

Explanation

The correct answer is B because arranging the racks to create hot and cold aisles helps optimize cooling efficiency in the datacenter. Option A is incorrect as sharing power outlets does not directly relate to the orientation of the racks. Option C is not relevant since electromagnetic interference is not influenced by rack orientation, and option D is incorrect because rack orientation does not significantly impact fire suppression capabilities.
