Which of the following is a UL computer media storage classification?

The correct classification for UL computer media storage is 150-4. This classification is an essential standard that applies specifically to the fire protection requirements for electronic media, including computer data storage devices. The UL 150-4 standard defines the criteria for ensuring that these media can withstand certain fire conditions, protecting the integrity of the stored data.

UL classifications are important as they help organizations determine the appropriate fire resistance of storage solutions. In this context, 150-4 indicates a specific level of fire endurance, allowing organizations to choose storage media that best suits their risk management needs.

The other classifications, while they may seem plausible, do not correspond to UL standards specifically designed for computer media storage, thereby increasing the relevance and importance of the 150-4 classification in this context.
