Which of the following statements is true of a virtual private cloud (VPC)? A VPC does not make use of a VPN (virtual private network). A VPC can be accessed only from within an organization. A VPC can be built on public cloud infrastructure. An organization generally stores its most sensitive data on a VPC.
The Correct Answer and Explanation is:
Correct Answer: A VPC can be built on public cloud infrastructure.
A Virtual Private Cloud (VPC) refers to a logically isolated section of a public cloud that allows organizations to launch and manage resources in a virtual network. This configuration provides a high level of control over the virtual networking environment, including selection of IP address ranges, creation of subnets, and configuration of route tables and network gateways.
The defining feature of a VPC is its foundation on public cloud infrastructure. Major cloud providers like Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform offer VPC services that provide customers with the appearance of a private cloud while utilizing the scalability and availability of the public cloud. In contrast to a fully private cloud built on on-premises infrastructure, a VPC enables businesses to take advantage of public cloud benefits such as reduced capital costs and elastic computing resources.
Another important aspect of a VPC is its compatibility with Virtual Private Networks (VPNs). VPNs are frequently used to securely connect a VPC to an on-premises data center or remote office. Therefore, the statement claiming a VPC does not use a VPN is inaccurate. VPNs enhance security and enable hybrid cloud deployments, where sensitive workloads may be distributed across both public and private environments.
Regarding access, a VPC is not restricted solely to internal organizational access. It can be configured to permit or restrict access based on specific requirements. Public-facing applications such as web servers can reside in a VPC with proper security groups and firewalls, while internal resources can be kept private.
Although some sensitive data may reside within a VPC, organizations typically use more secure, specialized environments or additional encryption and access control for their most sensitive information. A VPC offers security but not to the extent of a dedicated private cloud in highly regulated sectors.
