CompTIA Server+ (SK0-005) — Question 138

A hardware technician is installing 19 1U servers in a 42-unit rack. The technician needs to allocate enough space per server for optimal air flow.

Which of the following unit sizes should be allocated per server?

Answer options

• A. 1U
• B. 2U
• C. 3U
• D. 4U

Correct answer: A

Explanation

The correct answer is 1U because each server is designed to occupy 1U of rack space, allowing for the installation of all 19 servers within the 42U rack. The other options (2U, 3U, and 4U) would not be suitable as they would reduce the number of servers that can be installed, leading to inefficient use of rack space.
