1U stands for one unit and it is a standard unit of measurement for rack-mounted servers. It is equal to 1.75 inches (4.45 cm) in height. A 42U rack can accommodate 42 1U servers or a combination of servers with different unit sizes. Therefore, the unit size per server should be 1U if there are 19 1U servers in a 42U rack.References: (Objective 1.2)

The organization should retrieve the tapes from the cold site and test them to ensure they are properly maintained and usable during a DR scenario. A cold site is a location that has space and power for backup equipment, but no actual equipment installed or configured. The organization stores backup tapes of its servers at cold sites as a precaution in case of a disaster that affects its primary site. However, backup tapes can degrade over time due to environmental factors such as temperature, humidity, dust, or magnetic fields. Therefore, the organization should periodically retrieve the tapes from the cold site and test them on compatible equipment to verify their integrity and readability.

The per-concurrent user licensing model is a type of licensing model that restricts the number of active sessions or connections to a software application at any given time. This means that multiple users can share the same license, as long as they do not access the application simultaneously. This model is often used for applications that are accessed intermittently or for a short duration by different users, such as remote access software, web-based applications, or testing tools12.
