Answer 1

The correct option is D Both (a) and (b)

VPN is a virtual private network which is an extension of private network that includes links among shared or public networks, so option a is correct. For data flow in point-to-point link, data is wrapped with header having routing information which allows traversing of shared or public transit internetwork to reach its endpoint.
