N10-005 Question #823: Real Exam Question with Answer & Explanation

The correct answer is A: Point to Point. Remote access VPN creates an individual, dedicated tunnel between a single remote user and the VPN gateway, which is a point-to-point topology. Other topologies describe LAN physical layouts unrelated to VPN architecture.

Question

Which of the following network topologies is MOST likely used in remote access VPN?

Options

  • APoint to Point
  • BBus
  • CRing
  • DMesh

Explanation

Remote access VPN creates an individual, dedicated tunnel between a single remote user and the VPN gateway, which is a point-to-point topology. Other topologies describe LAN physical layouts unrelated to VPN architecture.

Common mistakes.

  • B. A bus topology connects all devices to a single shared medium and is a legacy LAN physical topology with no relation to VPN tunnel architecture.
  • C. A ring topology connects each device to exactly two neighbors in a closed loop, a LAN/WAN physical arrangement not applicable to remote access VPN design.
  • D. A mesh topology interconnects every node to multiple other nodes for redundancy; it is used in site-to-site WAN designs, not individual remote access VPN sessions.

Concept tested. Remote access VPN point-to-point topology
