Public cloud solutions have distinct characteristics that differentiate them from on-premise or private cloud deployments. Below is an explanation of the correct answers:

Multi-tenant server (A):Public cloud environments typically operate on a multi-tenant architecture, where multiple customers share the same infrastructure while maintaining data isolation. This approach optimizes resource utilization and reduces costs.

Lower total cost of ownership (C):Public cloud solutions eliminate the need for on-site hardware and software installations, reducing upfront capital expenditures and ongoing maintenance costs. This results in a lower total cost of ownership compared to traditional on-premise solutions.

Software installation on customer site (B):Public cloud solutions do not require software installation on the customer's premises, as the software is hosted and maintained by the cloud provider.

Perpetual license (D):Public cloud solutions typically operate on a subscription-based model rather than perpetual licensing, which is common in on-premise deployments.
