Which of the following is not an aspect of physical security that ought to be considered in the planning and design of a cloud datacenter facility?

The choice regarding the elevation of dropped ceilings is not typically considered an aspect of physical security when planning and designing a cloud datacenter facility. Physical security primarily focuses on safeguarding the facility and its contents from unauthorized access and threats, which include elements like vehicular approach and traffic control, the establishment of secure perimeters, and the implementation of fire suppression systems.

Each of these aspects plays a critical role in creating a secure environment. For example, controlling vehicular traffic helps in managing access to the facility and preventing unauthorized vehicle entry, while a secure perimeter serves as the first line of defense against unwanted intrusions. Fire suppression systems are essential for protecting the infrastructure and safeguarding data from fire damage.

On the other hand, the elevation of dropped ceilings is more related to building aesthetics, acoustics, and the hiding of infrastructure such as wiring and ductwork than it is to physical security. While it may have some indirect implications for environmental controls or maintenance, it does not directly enhance the physical security measures of a datacenter.
