Which services are most likely to be configured when deploying an IaaS cloud solution?

• A. Directory services
• B. Application services
• C. Storage services
• D. Backup services

Answer: (A)

When deploying an Infrastructure as a Service (IaaS) cloud solution, configuring services that help manage and authenticate users, such as directory services, is a common practice. Directory services facilitate centralized management of identity, access, and authentication, which are critical components in an IaaS environment. They allow organizations to manage user credentials and permissions efficiently, ensuring that appropriate access controls are enforced across the cloud infrastructure.

Storage services are also a significant component of IaaS, providing scalable and flexible data storage solutions, while backup services ensure data is safely stored and can be restored in case of a loss. However, these services primarily relate to storage management rather than user management. Conversely, application services generally pertain to software deployment and functionality rather than foundational infrastructure management, making them less central to the IaaS model compared to directory services. Thus, directory services emerge as a key focus within IaaS configurations for effective user and access management.
