An XYZ Corporation systems engineer, while making a sales call on the ABC Corporation headquarters, tried to access the XYZ sales demonstration folder to transfer a demonstration via FTP from an ABC conference room behind the firewall. The engineer could not reach XYZ through the remote-access VPN tunnel. From home the previous day, however, the engineer did connect to the XYZ sales demonstration folder and transferred the demonstration via IPsec over DSL.

To get the connection to work and transfer the demonstration, what should the engineer do?

A.
Change the MTU size on the IPsec client to account for the change from DSL to cable transmission.

B.
Enable the local LAN access option on the IPsec client.

C.
Enable the IPsec over TCP option on the IPsec client.

D.
Enable the clientless SSL VPN option on the PC.
