Certified Ethical Hacker (CEH) Practice Question

The NIST definition lists five essential characteristics of cloud computing. Resource pooling refers to the provider's practice of dynamically assigning pooled physical and virtual resources to multiple consumers in a multi-tenant model. This shared-infrastructure approach is what enables different customers' virtual machines to run on the same hardware, creating the possibility of cross-tenant side-channel attacks. Broad network access describes ubiquitous connectivity, rapid elasticity relates to automatic scaling, and measured service concerns usage-based metering; none of these directly explain why separate customers' workloads inhabit the same physical host.
