CompTIA Cloud+ (CV0-003) — Question 109

A systems administrator is securing a new email system for a large corporation. The administrator wants to ensure private corporate information is not emailed to external users. Which of the following would be MOST useful to accomplish this task?

Answer options

• A. DLP
• B. EDR
• C. DNSSEC
• D. SPF

Correct answer: A

Explanation

DLP (Data Loss Prevention) is specifically designed to protect sensitive information from being sent outside the organization, making it the most suitable option. EDR (Endpoint Detection and Response) focuses on threat detection on endpoints, while DNSSEC (Domain Name System Security Extensions) and SPF (Sender Policy Framework) are related to email authentication and security but do not prevent data leaks.
