An engineer is responsible for managing a private cloud environment at a software company. Company developers perform all programming in the cloud environment. There are two departments working on a h

Creating a baseline is used for performance monitoring and capacity planning, not for establishing resource isolation or access control for sensitive data.

Assigning Access Control Lists (ACLs) directly dictates which users or groups have permissions to specific resources, thereby preventing unauthorized viewing or access by other departments.

Verifying segmentation ensures that the network, compute, and storage environments for the classified product are properly isolated from other departments' resources, thus preventing unauthorized access and maintaining confidentiality.

Using thin provisioned storage is a method for optimizing storage allocation efficiency, which does not address security requirements for resource isolation or access control.

Automating patch deployments is a general security best practice for vulnerability management, but it does not directly fulfill the requirement for dedicated, isolated resources inaccessible to other departments.

While creating a tenant establishes a logical boundary, the specific technical actions to ensure isolation and access control are ACLs, segmentation verification, and secure authentication methods like PKI.

Deploying a PKI (Public Key Infrastructure) solution provides strong authentication mechanisms and encryption for communication, which is crucial for securing access to highly classified resources and preventing unauthorized viewing or tampering.
