Redundancy is provided by establishing multiple VPN servers. If one VPN server fails, client sessions are disconnected. However, clients can connect again by using a different VPN server. 4g LTE router To reduce the necessity to configure multiple connectoids one for each VPN server, use Network Load Balancing. However, don’t confuse redundancy with load balancing. Load balancing can be provided via round-robin Domain Name System DNS or clustering. Network load balancing, 4g LTE routera Microsoft clustering technology that spreads requests for a single IP address among several Microsoft Windows servers, can also provide load balancing in addition to scalability and redundancy. 4g LTE router If a VPN server fails, client sessions will also fail and the user will be prompted to log on again. The user’s new session will be managed by one of the other VPN servers free Cisco practice exam questions n the cluster. 4g LTE router Figure 7-7 shows Microsoft network load balancing.
