Certified Data Privacy Solutions Engineer (CDPSE) — Question 140

A travel agency wants to introduce a new cloud application for customers to access while traveling. Which of the following would BEST help to protect the application against unauthorized access?

Answer options

• A. Block login from known malicious Internet Protocol (IP) addresses.
• B. Protect the login with a web application firewall (WAF).
• C. Restrict login to permissible destinations based on IP geolocation.
• D. Secure login with multi-factor authentication (MFA).

Correct answer: D

Explanation

The correct answer is D because multi-factor authentication (MFA) adds an additional layer of security by requiring users to provide multiple forms of verification before accessing the application. Options A, B, and C, while helpful, do not offer the same level of protection against unauthorized access as MFA does, as they primarily focus on blocking or restricting access rather than verifying user identity.
