CompTIA Security+ (SY0-701) — Question 538

Which of the following is the best way to provide secure, remote access for employees while minimizing the exposure of a company’s internal network?

Answer options

• A. VPN
• B. LDAP
• C. FTP
• D. RADIUS

Correct answer: A

Explanation

A VPN (Virtual Private Network) creates a secure connection over the internet, effectively protecting the company's internal network from unauthorized access. LDAP (Lightweight Directory Access Protocol), FTP (File Transfer Protocol), and RADIUS (Remote Authentication Dial In User Service) do not provide the same level of secure remote access and are not designed specifically for minimizing exposure to the internal network.
