Explanation

A Virtual Private Network (VPN) creates an encrypted tunnel between the remote user and the internal network, allowing secure access to database resources without exposing them directly to the internet - exactly what's needed for remote access without compromising data security.

Why the distractors are wrong:

• B (Strong passwords): Passwords protect accounts but don't provide a mechanism for secure remote access - a user could still connect over an unencrypted channel.
• C (Firewall): Firewalls restrict traffic but typically block remote access rather than enabling it securely; alone, they don't solve the remote access problem.
• D (Parameter/perimeter network / DMZ): A DMZ isolates internet-facing services, but placing a database in a DMZ actually increases exposure rather than protecting it - databases should stay behind the internal network boundary.

Memory tip: Think "VPN = Virtual Private Tunnel." When remote users need in to a private network securely, a VPN is the answer - it's the only option that both enables access and encrypts it simultaneously.
