Which of the following descriptions about the functions that OpenStacki can provide is correct? ((Multiple choice)

Question

Options

• AResource allocation and scheduling
• BResource access and abstraction
• CApplication Lifecycle Management
• DSystem Administration and Maintenance

• A
  100% (23)

Explanation

All four options correctly describe functions that OpenStack provides, making this an "all of the above" scenario. OpenStack handles resource allocation and scheduling (A) through components like Nova, which schedules compute instances across physical hosts. It provides resource access and abstraction (B) by exposing hardware infrastructure-compute, storage, and networking-through unified APIs, hiding underlying physical complexity. Application lifecycle management (C) is supported via Heat (orchestration) and Murano (application catalog), enabling deployment and management of multi-component applications. System administration and maintenance (D) is covered through Horizon (dashboard), Keystone (identity), and operational tooling for managing the cloud platform itself.

Since all options are correct, there are no distractors to refute here-the question tests whether candidates know that OpenStack is a comprehensive cloud platform, not a single-purpose tool.

Memory tip: Think of OpenStack as a full-stack cloud OS - it must schedule resources, abstract hardware, manage apps, and administer itself. If a question lists broad IaaS/PaaS responsibilities, OpenStack likely covers all of them.
