Dell Technologies Proven Professional – Information Storage and Management (2023) — Question 7

In a modern data center environment, which mechanism secures internal assets while allowing Internet-based access to selected resources?

Answer options

• A. Virtual private network
• B. Demilitarized zone
• C. WWN zoning
• D. Virtual local area network

Correct answer: B

Explanation

The correct answer is B, as a Demilitarized Zone (DMZ) is specifically designed to secure internal networks while providing controlled access to external users. A Virtual Private Network (A) primarily encrypts connections for remote users, WWN zoning (C) is related to storage area networks, and a Virtual Local Area Network (D) segments networks but does not inherently provide external access security.
