CompTIA Cloud+ Practice Test

Which of the following is a common feature of cloud computing that allows for resource sharing among users?

1. Scalability

2. Multi-tenancy

3. On-demand self-service

4. Measured service

The correct answer is: Multi-tenancy

The feature that allows for resource sharing among users in cloud computing is multi-tenancy. This architecture enables multiple users, or tenants, to share a single instance of a software application or infrastructure without sacrificing the ability to securely manage their individual data and configurations. Each tenant operates in a logically isolated environment, ensuring that while resources are shared to optimize efficiency and reduce costs, user data remains private and secure. Multi-tenancy is fundamental to cloud computing as it maximizes resource utilization, allowing cloud providers to serve a larger number of customers on the same infrastructure. This model is prevalent in Software as a Service (SaaS) environments, where users access shared applications over the internet. Scalability refers to the capacity to handle increased loads by adding resources, and it is essential for accommodating growth but does not specifically address user resource sharing. On-demand self-service allows users to provision computing resources as needed, enhancing convenience but not necessarily involving shared resources. Measured service refers to resource consumption tracking and billing, focusing on usage precision rather than resource sharing among users.
