Which VPN technology has become the standard method of connecting remote endpoint devices back to the enterprise network?

1. L2TP

2. PPTP

3. IPsec

4. SSL

The correct answer is: SSL

The standard method of connecting remote endpoint devices back to the enterprise network is SSL VPN technology. This approach is favored because it operates over standard web ports (such as TCP port 443), enabling it to traverse most firewalls and NAT devices without requiring special configurations. SSL VPNs offer secure access to internal applications and resources, allowing remote users to connect easily without needing to establish a traditional VPN tunnel. This is particularly beneficial for organizations that require easy access for employees working from various locations or using different devices. Additionally, SSL VPNs can provide a richer user experience, offering features like clientless access and application-specific configurations that make them highly effective for modern enterprise environments. While the other technologies mentioned have their place, they are generally not as user-friendly or as widely adopted as SSL VPNs for remote access. For example, L2TP and PPTP are older protocols that may introduce complications with firewall traversal and security. IPsec, although robust and secure, is often more complex to configure and manage compared to SSL, especially in environments with a diverse range of devices and connectivity challenges. Thus, SSL VPN stands out as the preferred choice for remote access in contemporary network architectures.
