Office mode means that:
A . SecurID client assigns a routable MAC address. After the user authenticates for a tunnel, the VPN gateway assigns a routable IP address to the remote client.
B . Users authenticate with an Internet browser and use secure HTTPS connection.
C . Local ISP (Internet service Provider) assigns a non-routable IP address to the remote user.
D . Allows a security gateway to assign a remote client an IP address. After the user authenticates for a tunnel, the VPN gateway assigns a routable IP address to the remote client.
Answer: D
Explanation:
Office Mode enables a Security Gateway to assign internal IP addresses to SecureClient users. This IP address will not be exposed to the public network, but is encapsulated inside the VPN tunnel between the client and the Gateway. The IP to be used externally should be assigned to the client in the usual way by the Internet Service provider used for the Internet connection. This mode allows a Security Administrator to control which addresses are used by remote clients inside the local network and makes them part of the local network. The mechanism is based on an IKE protocol extension through which the Security Gateway can send an internal IP address to the client.
