CompTIA Network+ (N10-009) — Question 77

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 encryption and authentication for the data being transmitted between sites, ensuring confidentiality and integrity. In contrast, GRE does not provide security features on its own, while VXLAN and IKE are not primarily focused on site-to-site security.
