CCNA: Cisco Certified Network Associate — Question 240

What is a function of a remote access VPN?

Answer options

• A. establishes a secure tunnel between two branch sites
• B. uses cryptographic tunneling to protect the privacy of data for multiple users simultaneously
• C. used exclusively when a user is connected to a company's internal network
• D. allows the users to access company internal network resources through a secure tunnel

Correct answer: D

Explanation

The correct answer is D because a remote access VPN specifically allows users to connect to their company’s internal resources securely over the internet. Option A refers to site-to-site VPNs, which connect branch sites rather than individual users. Option B describes a feature of VPNs but does not specifically address remote access. Option C is incorrect as remote access VPNs are used to connect users who are not on the internal network.
