Implementing Cisco Network Security (IINS, legacy) — Question 110

Referencing the CIA model, in which scenario is a hash-only function most appropriate?

Answer options

• A. securing data at rest
• B. securing wireless transmissions
• C. securing data in files
• D. securing real-time traffic

Correct answer: A

Explanation

A hash-only function is primarily used to ensure the integrity of data at rest by verifying that it has not been altered. While it can be applied to files, its best use is in securing stored data, rather than in securing transmissions or real-time traffic where additional encryption is necessary.
