Availability

Availability

• A. Data integrity is maintained during transfers
• B. Devices can only be accessed by administrators
• C. Networks are reduced in complexity
• D. Authorized users always have access to resources

Answer: (D)

Availability means ensuring that authorized users can access the resources they need when they need them, even in the face of failures or heavy use. In practice, that means systems are up, services respond quickly, and access is reliable for legitimate users. The option that describes authorized users always having access to resources aligns with this idea: availability is about reliable access for those who are permitted to use the resources. It emphasizes keeping services reachable and responsive for real users. Other options touch on different security goals. Data integrity during transfers relates to ensuring information isn’t altered in transit. Restricting device access to administrators involves access control and confidentiality, not whether end users can reach resources when needed. Worrying about networks being less complex speaks to manageability or efficiency, not the ongoing ability to access resources.
