Implementing and Operating Cisco Security Core Technologies (SCOR) — Question 262

Which technology should be used to help prevent an attacker from stealing usernames and passwords of users within an organization?

Answer options

• A. RADIUS-based REAP
• B. fingerprinting
• C. Dynamic ARP Inspection
• D. multifactor authentication

Correct answer: C

Explanation

The correct answer is C, Dynamic ARP Inspection, as it helps ensure that only valid ARP requests and responses are processed, preventing man-in-the-middle attacks that could lead to credential theft. Options A and B do not specifically address the issue of username and password theft, while D, multifactor authentication, is effective for securing accounts but does not prevent the initial theft of credentials themselves.
