An administrator has configured two-factor authentication to strengthen SSL VPN access. Which additional best practice can an administrator implement?

Configuring Source IP Pools defines the IP addresses assigned to SSL VPN clients and is an operational necessity, but it does not directly enhance the security posture of the client or the connection itself.

Configuring split tunneling allows some traffic to bypass the VPN tunnel, which can reduce security by allowing client devices to access the internet directly, potentially exposing them to threats outside corporate security controls.

Configuring different SSL VPN realms helps organize and manage user access by providing different login experiences or access permissions, but it does not inherently strengthen the security of the connection or the client device's compliance.

Configuring host check enforces security compliance on client devices before they can establish an SSL VPN connection. This ensures that only devices meeting specific security criteria, such as having updated antivirus software or specific operating system patches, are granted access, significantly reducing the risk of compromise.
