CompTIA Network+ (N10-009) — Question 91

Which of the following does a hash provide?

Answer options

• A. Non-repudiation
• B. Integrity
• C. Confidentiality
• D. Availability

Correct answer: B

Explanation

A hash primarily ensures data integrity by producing a fixed-size string from input data, which helps in verifying that the data has not been altered. Non-repudiation is more about proving the origin of data, confidentiality relates to keeping data secret, and availability ensures that data is accessible, which are not functions of a hash.
