Question
A network administrator is planning to host a company application in the cloud, making the application available for all internal and third-party users. Which of the following concepts describes this arrangement?
- A. Multitenancy Correct
- B. VPC
- C. NFV
- D. SaaS
Explanation
Multitenancy means a single cloud-hosted instance of an application or infrastructure serves several separate groups of users (tenants), here the company's internal users and its third-party users, while keeping their data and access logically isolated. SaaS describes a service model in which a provider delivers a finished application to customers; the administrator here is hosting the company's own application rather than consuming a provider's software. A VPC is an isolated virtual network segment in a public cloud, and NFV replaces dedicated network appliances with virtualized functions; neither describes sharing one application among different user groups.
