CompTIA Network+ (N10-008) — Question 568

Which of the following is the most cost-effective way for a network administrator to establish a persistent, secure connection between two facilities?

Answer options

Correct answer: A

Explanation

A Site-to-site VPN is the most cost-effective solution as it utilizes existing internet infrastructure to create secure connections without the need for expensive dedicated lines. An SSH tunnel is typically used for secure remote access, not inter-facility connections, and an API gateway does not establish a direct network connection. A dedicated line, while secure, is much more costly due to the infrastructure required.
