CompTIA Security+ (SY0-701) — Question 518

Which of the following is used to improve security and overall functionality without losing critical application data?

Answer options

• A. Reformatting
• B. Decommissioning
• C. Patching
• D. Encryption

Correct answer: C

Explanation

Patching is the correct answer because it involves applying updates to software that fix vulnerabilities and improve functionality without deleting or compromising existing data. In contrast, reformatting and decommissioning can result in loss of data, while encryption is focused on securing data rather than improving system functionality.
