Which statement regarding SRS is true?

The correct statement regarding SRS (Site Requirements Specification) is that overhead distribution allows greater flexibility for site expansion. This means that when electrical systems and distribution infrastructure are installed overhead, it becomes much easier to modify, add, or relocate equipment as the needs of the site change. Overhead systems can accommodate new power distribution pathways and can adapt to changing layouts within a facility, such as when new equipment is introduced or when existing systems are expanded. This flexibility is particularly important in dynamic environments where technology and equipment can evolve rapidly.

In contrast, the other statements do not accurately reflect broader industry practices or definitions. For instance, while various methods exist for electromagnetic interference (EMI) suppression, claiming that SRS is the only method overlooks other effective techniques. The statement about ITE (Information Technology Equipment) sites always utilizing raised floors for cooling is not universally true, as there are many cooling solutions available. Similarly, the assertion that all sites use cross-flow cooling is inaccurate since cooling methods can vary widely based on specific site requirements and design choices. Each of these points emphasizes the importance of understanding the diverse strategies and practices employed within site requirements and management.
