CompTIA Security+ (SY0-501) — Question 350

A member of the human resources department received the following email message after sending an email containing benefit and tax information to a candidate:
`Your message has been quarantined for the following policy violation: external potential_PII. Please contact the IT security administrator for further details`.
Which of the following BEST describes why this message was received?

Answer options

• A. The DLP system flagged the message.
• B. The mail gateway prevented the message from being sent to personal email addresses.
• C. The company firewall blocked the recipient's IP address.
• D. The file integrity check failed for the attached files.

Correct answer: A

Explanation

The correct answer is A because the DLP (Data Loss Prevention) system is designed to detect and prevent the transmission of sensitive information, such as personally identifiable information (PII). Options B, C, and D are incorrect because they do not directly relate to the quarantine action taken due to the potential PII policy violation.
