CompTIA A+ Core 1 (220-1101) — Question 28

Which of the following is a method that can be used to securely connect a remote user's laptop to a corporate server?

Answer options

• A. WAN
• B. VPN
• C. SSL
• D. DHCP

Correct answer: B

Explanation

A VPN (Virtual Private Network) creates a secure tunnel for data transmission between the remote laptop and the corporate server, ensuring confidentiality and integrity. WAN (Wide Area Network) is a type of network connection but does not inherently provide security. SSL (Secure Sockets Layer) is a protocol for securing communications, but it does not connect devices directly. DHCP (Dynamic Host Configuration Protocol) is used for assigning IP addresses and does not provide secure connections.
