What is the benefit of using the Cisco Easy VPN Server feature along with the Cisco software VPN client for implementing remote-access VPNs? ()A、 The Cisco Easy VPN Server feature and the Cisco software VPN client use the same GUI configuration tool to simplify remote-access VPN configurations.B、 The Cisco Easy VPN Server feature allows the Cisco software VPN client to receive its security policies from the central site VPN device. This minimizes the configuration requirements at the remote location for large remote access VPN deployments.C、 The Cisco Easy VPN Server feature and the Cisco software VPN client use hardware-based encryption to reduce the CPU overhead of the central site VPN router.D、 The Cisco Easy VPN Server feature and the Cisco software VPN client enable scalable remote-access VPNs deployment by using a thick client/thin server model where the central site VPN router can handle thousands of incoming VPN connections.
Which three statements about the Cisco Easy VPN feature are true?()A、If the VPN server is configured for Xauth, the VPN client waits for a username / password challenge.B、The Cisco Easy VPN feature only supports transform sets that provide authentication and encryption.C、The VPN client initiates aggressive mode (AM) if a pre-shared key is used for authentication during the IKE phase 1 process.D、The VPN client verifies a server username/password challenge by using a AAA authentication server that supports TACACS+ or RADIUS.E、The VPN server can only be enabled on Cisco PIX Firewalls and Cisco VPN 3000 series concentrators.F、When connecting with a VPN client,the VPN server must be configured for ISAKMP group 1,2 or 5.
部署IPSEC VPN 网络需要考虑如何同时进行Internet 访问,从缓解中心节点压力的角度考虑,建议采用分布式的Internet 访问部署,此时分支节点需要进行VPN 流量和Internet 流量的分流。
用户现在希望两个VPN的业务主机都能够访问internet,为了做到集中访问和集中控制,统一在核心节点A侧再增加一个VRF专门进行internet的访问。 已知VPN1的VRF的RT配置如下: ip vpn-instance vpn-1; vpn-target A export-extcommunity; vpn-target A import-extcommunity 已知VPN2的VRF的RT配置如下: ip vpn-instance vpn-2; vpn-target B export-extcommunity; vpn-target B import-extcommunity请写出superVPN的RT规划。以及对现有的两个VPN的RT规则的改变。(如果需要使用新的RT规则,可以使用字母C、D……代替)
