Which of the following has infrastructure security managed and owned by the vendor?

The correct answer is: C. public

A public cloud is a type of cloud computing that provides infrastructure and services to the general public over the Internet. The infrastructure is owned and managed by a cloud provider, such as Amazon Web Services (AWS), Microsoft Azure, or Google Cloud Platform.

In a public cloud, the customer does not have any control over the underlying infrastructure. The cloud provider is responsible for security, availability, and performance.

Public clouds are often used by businesses that need to scale quickly or that do not have the resources to manage their own infrastructure.

Here is a brief explanation of each option:

• Hybrid cloud is a combination of public and private clouds. The customer has control over some of the infrastructure, but the cloud provider is responsible for the rest. Hybrid clouds are often used by businesses that need to balance the cost and flexibility of public clouds with the security and control of private clouds.
• Private/community cloud is a cloud that is owned and operated by a single organization or a group of organizations. The cloud is not available to the general public. Private/community clouds are often used by businesses that need to protect sensitive data or that have specific requirements for security and compliance.
• None of the mentioned is not a valid option.
