CompTIA A+ 220-1101 (V14) Practice Question

Cloud providers follow a shared-responsibility model: they secure the underlying facilities and virtualization layers, but customers remain responsible for operating-system, application, identity, and data security. Therefore, relying on the provider to handle all security is not a benefit. Genuine advantages include rapid elasticity that scales resources up or down automatically, pay-as-you-go pricing that minimizes upfront capital expense, and fully managed services (such as database clusters) that reduce the need for deep in-house specialization.
