Which two types of VPNs are examples of enterprise-managed remote access VPNs? (Choose two.)
- clientless SSL VPN
- client-based IPsec VPN
- IPsec VPN
- IPsec Virtual Tunnel Interface VPN
- GRE over IPsec VPN
Enterprise managed VPNs can be deployed in two configurations:
- Remote Access VPN – This VPN is created dynamically when required to establish a secure connection between a client and a VPN server. Remote access VPNs include client-based IPsec VPNs and clientless SSL VPNs.
- Site-to-site VPN – This VPN is created when interconnecting devices are preconfigured with information to establish a secure tunnel. VPN traffic is encrypted only between the interconnecting devices, and internal hosts have no knowledge that a VPN is used. Site-to-site VPNs include IPsec, GRE over IPsec, Cisco Dynamic Multipoint (DMVPN), and IPsec Virtual Tunnel Interface (VTI) VPNs.
