Which of the following is an example of a utility in the physical resource pool?

In the context of a physical resource pool, utilities refer to the essential infrastructure components that support the operation of IT systems. Power and cooling systems are critical for the proper functioning of servers and other hardware, ensuring they operate within safe temperature ranges and receive the necessary electrical supply.

Power systems are designed to provide uninterrupted electricity to prevent system failures or downtime. Cooling systems, on the other hand, help dissipate heat generated by hardware components, maintaining optimal operating conditions. Together, they ensure reliability and efficiency in data centers or any environment where physical resources are managed.

The other options do not represent utilities in the same way. Network cables, while important, are more about connectivity than providing essential infrastructure support. Data processing units fall under the category of computational hardware rather than utilities. Software licenses pertain to the legal permission to use certain software but do not influence the physical operational requirements necessary for running IT systems.
