CompTIA Network+ (N10-008) — Question 570

Which of the following is the most secure way to provide site-to-site connectivity?

Answer options

• A. VXLAN
• B. IKE
• C. GRE
• D. IPSec

Correct answer: D

Explanation

IPSec is the most secure option because it provides strong encryption and authentication for data packets transmitted between sites. VXLAN, GRE, and IKE, while useful for tunneling and key exchange, do not inherently offer the same level of security as IPSec does for site-to-site connections.
