CompTIA Network+ (N10-007) — Question 190

A network technician is configuring user access to a VPN concentrator and has been advised to use a protocol that supports encryption over UDP. Which of the following protocols has the technician MOST likely configured for client use?

Answer options

• A. TFTP
• B. DTLS
• C. DNS
• D. SNMP

Correct answer: B

Explanation

DTLS (Datagram Transport Layer Security) is designed to provide encryption over UDP, making it the most suitable choice for securing VPN connections. TFTP, DNS, and SNMP do not offer encryption capabilities, which makes them inappropriate for this scenario.
