Name a key difference between public cloud and on-premises network design considerations.

• A. Public cloud abstracts physical resources and uses provider-managed security.
• B. On-premises deployments use provider-managed hardware.
• C. Public cloud requires direct hardware access by users.
• D. Public cloud abstracts physical resources and uses provider-managed security; on-premises requires direct hardware and controlled security boundaries.

Answer: (D)

Public cloud designs hide the physical hardware behind virtualization, and the provider handles most of the infrastructure security. You configure virtual networks, subnets, security groups, and identities, focusing on how resources can connect and be isolated. The underlying hardware, virtualization layer, and core security controls are managed by the provider, which is why you don’t deal with bare-metal gear directly. On the other hand, on-premises means you own and manage the actual servers, networking gear, and data center facilities. You’re responsible for procuring, deploying, patching, and securing the hardware itself, as well as defining and enforcing security boundaries through firewalls, segmentation, and access controls. So the key difference is that cloud abstracts hardware and uses provider-managed security, while on-premises requires direct hardware management and tightly controlled security boundaries. This captures how network design decisions differ between the two models.
