When designing a cloud data center, which of the following aspects is not necessary to ensure continuity of operations during contingency operations?

Access to clean water is crucial for cooling systems (e.g., chillers) in many data centers, directly impacting operational continuity.

A broadband data connection is absolutely critical for cloud data centers to maintain connectivity with users, other data centers, and the internet.

While battery backup (UPS) is essential for bridging short power outages until generators can start, "extended battery backup" typically implies a very long-duration battery system, which is less common for sustained disaster recovery and continuity than redundant generator systems. For contingency operations, the focus is more on primary and secondary power sources (e.g., utility + generators) and robust connectivity, not just very long battery runtimes.

Physical access to the data center is necessary for maintenance, repairs, security, and manual intervention during critical outages or contingency events that cannot be resolved remotely.
