The correct answer is B. Organizations do not need to make upfront capital investments in cloud security. Here's why:

Context of the Question: The question asks about the benefits of the operational expenditure (OpEx) model for cloud security.

Google Cloud Product Relevance:

The OpEx model involves paying for cloud resources and services on a pay-as-you-go basis, avoiding the need for large upfront capital expenditures (CapEx) for security hardware or software.

In the cloud, security services (such as firewalls, encryption, and monitoring tools) are provided as managed services, which organizations can subscribe to and pay for based on usage. This model allows for more flexibility and scalability in managing security needs and costs.

Why Not Other Options:

A. Organizations can deploy custom security hardware: In the cloud, most security needs are met through managed services rather than deploying custom hardware.

C. Organizations do not need to configure any security settings for cloud resources: This is incorrect, as organizations are responsible for configuring security settings for their applications and data.

D. The cloud provider guarantees security: The cloud provider guarantees the security of the infrastructure, but the customer is responsible for securing their applications, data, and access controls.
