CompTIA Network+ (N10-008) — Question 68

A network administrator is designing a new datacenter in a different region that will need to communicate to the old datacenter with a secure connection. Which of the following access methods would provide the BEST security for this new datacenter?

Answer options

• A. Virtual network computing
• B. Secure Socket Shell
• C. In-band connection
• D. Site-to-site VPN

Correct answer: D

Explanation

A Site-to-site VPN provides a secure tunnel between two networks, ensuring that data transmitted between the new and old datacenters is encrypted and protected from unauthorized access. In contrast, Virtual network computing and Secure Socket Shell are more suited for remote access but do not provide the same level of network-wide security as a VPN. An in-band connection lacks the necessary security measures for sensitive communications between datacenters.
