• security
• scalability
• cost savings
• compatibility
  

  Answers Explanation & Hints: A benefit of VPNs is scalability because organizations can use the Internet and easily add new users without adding significant infrastructure. Security is provided by using encryption and authentication protocols to protect data. Another benefit is compatibility because VPNs can be implemented across a wide variety of WAN connections. Organizations also benefit from cost savings because VPNs reduce connectivity costs while simultaneously increasing remote connection bandwidth.
