[Year 12 IT Apps] Q A10

[Selina Dennis]

Hi John,

A VPN can be considered a "more secure" network-in-a-network. It "uses the
web" in that it tunnels through the same network systems/etc as everything
else. While VPNs provide a layer of security that may perhaps not be
available under a regular network connection, the true benefit of using a
VPN is to provide functionality to a community that might not otherwise be
available for them to use.

In this context, the answer that involved web conferencing (and a WAN) is
the most appropriate, most especially due to the key phrase "in real time".
I don't believe it was the best example, but it's certainly the only correct
response in the multiple choice.

Hope that helps.

Regards,

Can someone who knows more than me about this please tell me how using a VPN
is web conferencing? I accept that D is the intended answer but thought that
web conferencing used the web while VPN's did not.
