VPN Technologies

A company wants to deploy a VPN between its Head Quarter and more than 100 Branch Offices. It needs a solution that:

  1. Reduces deployment complexity
  2. Simplifies branch communications
  3. Provides branch-to-branch connectivity
  4. Is cost-effective
  5. Provides strong encryption

Select the best option from the choices below to recommend for implementation.

  • A MPLS
  • B IPSEC
  • C DMVPN
  • D GRE
Explanation

DMVPN combines multipoint GRE, NHRP, and IPsec to scale VPN connectivity across many branches with reduced configuration overhead. It creates direct, on-demand spoke-to-spoke IPsec tunnels for branch-to-branch communication while providing IPsec encryption, avoiding the cost and administrative burden of a large static full-mesh VPN or MPLS deployment.
