An employee accidentally deletes critical files from a server, interrupting business operations. Which impact is most direct?

### Why this is right The stated consequence is that users cannot access files needed for business operations. That is an availability impact, regardless of whether the deletion was intentional or accidental. ### The concept Availability is about access to usable systems and data. Accidental deletion can interrupt operations and cause downtime. Integrity may also be affected indirectly if restoration introduces inconsistencies, but the scenario's immediate consequence is loss of access. A deletion does not by itself prove that information was disclosed or that an attacker changed it. ### The other options - **B. Confidentiality, because the files were deleted**: deletion concerns loss or change, not disclosure to an unauthorized person. - **C. Integrity, because every deletion proves an attacker changed the files**: deletion may affect integrity, but it does not prove an attacker was involved. - **D. Confidentiality, because the server is offline**: a server being offline prevents access, which is an availability issue. ### Remember Accidental causes can still produce security impacts; classify the effect, not the intent.
