CompTIA Security+ (SY0-501) — Question 883

A user attempts to send an email to an external domain and quickly receives a bounce-back message. The user then contacts the help desk stating the message is important and needs to be delivered immediately. While digging through the email logs, a systems administrator finds the email and bounce-back details:
Your email has been rejected because it appears to contain SSN information. Sending SSN information via email to external recipients violates company policy.
Which of the following technologies successfully stopped the email from being sent?

Answer options

• A. DLP
• B. UTM
• C. WAF
• D. DEP

Correct answer: A

Explanation

The correct answer is A, DLP (Data Loss Prevention), which is designed to detect and prevent sensitive information, such as SSN data, from being sent outside the organization. The other options, UTM (Unified Threat Management), WAF (Web Application Firewall), and DEP (Data Execution Prevention), do not specifically target the prevention of sensitive data transmission like DLP does.
