CompTIA Server+ SK0-005 Practice Question
A systems administrator is preparing a standard 42U, 19-inch four-post cabinet for a new batch of identical 2U rack-mount servers. The design already reserves 6U at the top for network switches and horizontal cable managers and sets aside another 4U elsewhere in the cabinet for blank panels to maintain front-to-back airflow. Assuming no other equipment will be installed, how many of the 2U servers can the administrator install in the cabinet without exceeding its maximum usable height?
