The correct answer is C. An internal cloud is a cloud that sits behind a corporate firewall. It is a private cloud that is used by a single organization. It is often used to store sensitive data or to run applications that require a high level of security.
Option A is incorrect because an internal cloud is not an overhanging threat. It is a secure way to store and access data.
Option B is incorrect because an internal cloud is not a career risk for a CIO. In fact, many CIOs are now responsible for managing their organization’s internal cloud.
Option D is incorrect because an internal cloud is not a group of knowledge workers who use a social network for water-cooler gossip. It is a private cloud that is used by a single organization.
