CompTIA ITF+ (FC0-U61) — Question 308

A user received an account compromise notice from an online retailer. Two weeks later, the user received another notice stating the new compromise used the credentials from the first compromise. Which of the following password best practices MOST likely would have prevented the second compromise?

Answer options

• A. Password age
• B. Password complexity
• C. Password reuse
• D. Password length

Correct answer: C

Explanation

The correct answer is C, as password reuse directly contributed to the second compromise; using the same password across different accounts makes them vulnerable. Options A (Password age), B (Password complexity), and D (Password length) are important security measures but do not specifically address the issue of reusing passwords across multiple accounts.
